Executive Summary 

This report is submitted as partial fulfillment of the terms of the Strategic Environmental Research and Development Program (SERDP)-funded project CS-1083. The purpose of this research is to assess the effects of military training noise on the endangered 

Red-cockaded Woodpecker (RCW) and to develop assessment methodology. The results of 

this research will provide a scientific basis for RCW management protocols, and will partially satisfy requirements of a 1996 U.S. Fish and Wildlife Service (USFWS) biological 

opinion that requires the Army to assess effects of implementing the 1996 “Management 

Guidelines for the RCW on Army Installations.” These new guidelines significantly reduce restrictions on training for military installations on which RCWs are present. 

These installations include Fort Stewart, GA; Fort Bragg, NC; Fort Benning, GA; Fort 

Polk, LA; Fort Gordon, GA; Fort Jackson, SC; Camp Lajeune, NC; Eglin Air Force Base 

(AFB), FL; and Camp Blanding, FL. This research is being conducted jointly by the U.S. 

Army Construction Engineering Research Laboratory (CERL), an element of the U.S. 

Army Engineer Research and Development Center (ERDC); Fort Stewart, and the U.S. 

Army Forces Command (FORSCOM). The project was developed by CERL in coordination with FORSCOM, the USFWS RCW Recovery Coordinator and Region 4 office, the 

Fort Stewart Director of Training, the Fort Stewart Department of Public Works (DPW) 

Fish and Wildlife Branch, and the Army Threatened and Endangered Species (TES) User 

Group. 

During this second year of the study, we experimentally tested RCW response to controlled military training noise events under realistic conditions, namely .50-caliber blank 

fire and artillery simulators. We measured both proximate response behavior and nesting success, while continuing to measure baseline behavioral data from undisturbed 

sites. Measured levels of experimental noise did not affect RCW nesting success or productivity. RCW flush response was shown to increase as stimulus distance decreased, 

regardless of stimulus type. Woodpeckers returned to their nests relatively quickly after 

being flushed. Noise levels within RCW nest cavities were substantially louder than levels recorded at the base of the tree. It is important to note that the data collected to this 

point are sufficient to confirm statistical power to make strong conclusions or to establish 

reliable noise dose-response relationships or thresholds. The data collected to this point 

are sufficient to confirm that the project technical approach is appropriate and that the 

research objectives will be achieved.

1 Introduction 

Background 

The Endangered Species Act requires that all Federal agencies carry out programs to conserve threatened and endangered species (TES) and to evaluate the 

impacts of Federal activities on listed species (Scott et al. 1994). TES management on military installations, particularly that involving the Red-cockaded 

Woodpecker (RCW), has raised questions about the interaction between Army 

training and the conservation of Red-cockaded Woodpeckers on military lands. 

The goal of RCW management on Fort Stewart is to recover the population while 

eliminating conflicts with the training mission by eliminating the need for training restrictions (Fort Stewart Endangered Species Management Planning 

[ESMP] Team 1998). A brief summary of legal requirements is presented in Appendix A. Because noise management has traditionally focused on minimizing 

human annoyance, loud activities have often been relocated to sparsely populated areas where wildlife resides. This has led to increased interactions between military activity and wildlife (Holland 1991). Increasing importance has 

been placed on determining the extent of noise impacts on wildlife (Bowles 1995), 

especially threatened and endangered species (Delaney et al. 1999; Pater et al. 

1999). 

The Red-cockaded Woodpecker (Picoides borealis) is an endangered species that 

inhabits mature, open pine forests of the southeastern United States (Figure 1; 

Jackson 1994). Historically, RCW populations were distributed throughout the 

South from eastern Texas to the Atlantic coast, and north to New Jersey (Jackson 1987). The distribution has been reduced with the extirpation of RCWs from 

New Jersey (Lawrence 1867), Missouri (Cunningham 1946 as cited in Jackson 

1987), and most recently Maryland (Devlin et al. 1980). The majority of RCWs 

are currently restricted to public lands, namely National Forests, military installations, and National Wildlife Refuges (Jackson 1978, Lennartz et al. 1983). 

Military installations, in particular, are gaining recognition as a valuable resource in the recovery of TES (Jordan et al. 1995). It has been estimated that 

nearly a quarter of the remaining RCWs are located on nine military installations in the southeast (Costa 1992), which includes the Fort Stewart population. 

Such a close association has led to increased conflicts between TES conservation 
10 CERL TR 00-13 

requirements and the military’s mission of maintaining a high degree of combat 

readiness (Jordan et al. 1995). 

Figure 1. Adult Red-cockaded Woodpecker 

delivering prey to the nest. 

In 1984 the Army initially established a 200-ft (61-m) buffer zone around all 

RCW cavity trees to protect nesting habitat and identify RCW management 

units. In 1996, the Department of the Army (DA) issued revised guidelines for 

the management of RCWs on military lands, to reduce training restrictions, and 

increase adaptive management of the RCW and its habitat. These guidelines are 

scheduled to go in to effect by early 2000. Under the revised guidelines, certain 

transient military activities are permitted within 50 ft (15 m) of RCW cavity 

trees. These include: (1) military vehicle and personnel travel, including armor; 

(2) .50-caliber machine gun blank fire and 7.62-mm blank fire and below; (3) artillery/hand grenade simulators and Hoffman type devices; (4) hand digging of 

hasty individual fighting positions; (5) use of smoke grenades and star cluster/parachute flares; and (6) smoke and haze operation (see Hayden 1997 for a 

more detailed description of past and current Army guidelines for RCWs). A 

1996 USFWS biological opinion requires the Army to assess effects due to implementing the 1996 guidelines (Jordan et al. 1997). The current project will 

provide an important aspect of this required assessment. 
CERL TR 00-13 11 

The Fort Stewart Fish and Wildlife Directorate prepared an Endangered Species 

Management Plan (Fort Stewart ESMP Team 1998) for the installation that detailed changes under these revised guidelines: (1) consideration will be given 

jointly to training mission requirements and RCW biological requirements when 

implementing ESMP; (2) reduction in off-limit area for thru-cluster maneuver 

traffic around cluster trees from 200 ft (61 m) to 50 ft (15 m); and (3) the types of 

training activities allowed within RCW clusters will be expanded. 

Objectives 

The primary research objective of this multiyear study is to determine the impact of certain types of training noise on the endangered Red-cockaded Woodpecker. This will require that we develop dose-response threshold relationships 

for quantifying RCW responses to noise levels and stimulus distances, and relate 

these to nesting success. A second objective is to develop and disseminate costeffective techniques for documenting the effects of training noise on TES populations. These techniques include the capability to characterize noise stimuli, to 

document behavioral responses, and to determine resulting population effects 

due to military noise. Achieving these objectives will provide a means to manage 

impact on both military training capability and TES, and will provide a factual 

basis for mitigation and management protocols and guidelines. This research 

directly addresses the #1 Army Conservation Pillar User Requirement, which is 

concerned with impacts of military operations on threatened and endangered 

species. The results of this research will partially satisfy requirements of the 

1996 USFWS biological opinion (Jordan et al. 1997) that requires the Army to 

assess effects due to implementing the 1996 “Management Guidelines for the 

RCW on Army Installations.”

Approach 

Chapter 3 presents details of the technical approach used in this research. The 

chapter includes discussions of the study area, cluster selection, impact measures, response protocols, nesting success, video surveillance, sound instrumentation and recording, sound metrics, and statistical analysis. 

Scope 

All aspects of the research plan were reviewed and approved by the USFWS and 

Fort Stewart before monitoring activity began. Results from this research apply 
12 CERL TR 00-13 

directly to Fort Stewart, but may also be applicable to other installations in the 

southeastern United States where RCWs are exposed to similar noise. This 

study will use population data collected at Fort Stewart and other installations 

under a Forces Command (FORSCOM) program. Specific evaluation of impact of 

maneuver training activities is being conducted under a separate coordinated 

research effort. Training noise sources examined during this study include artillery simulators, .50-caliber blank fire, large-caliber live fire, small-arms live fire, 

grenade simulators, and helicopter flights. RCW response to other military activity, such as vehicle noise associated with maneuver training, aircraft overflights, and Multiple Launch Rocket System (MLRS) fire, will be documented 

opportunistically, but is not of high priority in this study. 

Mode of Technology Transfer 

Products of this research will be provided directly to the Military Services for use 

during consultation with the USFWS and for development of management protocols. This aspect of the transition plan will directly help to alleviate impacts on 

military training capability and will provide information to the military that will 

guide effective management of impacts on endangered species populations. 

Other technology transfer methods will include technical papers and journal articles and TES and noise workshops. The information will also be disseminated 

through the Environmental Noise Program Office of the U.S. Army Center for 

Health Promotion and Preventive Medicine, the Army TES User Group, and the 

U.S. Air Force (USAF) International Bibliography on Noise (IBON). Other forums for dissemination include the North Atlantic Treaty Organization (NATO) 

Committee for Challenges to Modern Society (CCMS) subcommittees for noise 

effects, the International Committee on the Biological Effects of Noise (ICBEN), 

the Acoustical Society of America Animal Bioacoustics technical committee, and 

the Department of Defense (DoD) Committee on Environmental Noise. 
CERL TR 00-13 13 

2 Literature Review 

Noise disturbance studies have often been anecdotal and fail to quantitatively 

measure either the stimulus or the behavioral response related to the animal’s 

fitness. Predictive models for the relationship between disturbance dosage and 

quantifiable effects are even more scarce (Awbrey and Bowles 1990; Grubb and 

King 1991; Grubb and Bowerman 1997). Although many types of human disturbance have been reported as affecting birds (Fyfe and Olendorff 1976), very little 

research has addressed the effects of human activity on woodpeckers, especially 

the endangered Red-cockaded Woodpecker (Charbonneau et al. 1983; Jackson 

1983; Beaty 1986; Jackson and Parris 1995; The Nature Conservancy [TNC] 

1996; Pater et al. 1999). 

Few researchers have directly compared differences in bird responsiveness between aerial and ground-based disturbances (Bowles et al. 1990). Studies that 

have examined the effects of aircraft activity on nesting birds (e.g., Platt 1977; 

Windsor 1977; Ellis 1981; Anderson et al. 1989) have often noted a slight but 

nonsignificant decrease in nesting success and productivity for disturbed versus 

undisturbed nests. Anderson et al. (1989) noted a slight decline in the nesting 

success of experimental Red-tailed Hawk (Buteo jamaicensis) nests versus control nests (80 percent experimental versus 86 percent control success) after helicopter disturbances. 

In contrast, ground-based disturbances appear to have a greater effect than aerial disturbances on the nesting success of some bird species. In their classification tree model of Bald Eagle (Haliaeetus leucocephalus) responses to various anthropogenic disturbances, Grubb and King (1991) determined that Bald Eagles 

in Arizona showed the highest response frequency and severity of response toward ground-based disturbances, followed by aquatic, and lastly by aerial disturbances. Delaney et al. (1999) reported similar findings for Mexican Spotted 

Owl (Strix occidentalis lucida) response to military helicopter activity and chain 

saws, observing that chain saws elicited a greater flush response rate than helicopters at comparable distances and noise levels.

A bird’s behavior during the nesting season is an important determinant of its 

ultimate nesting success or failure (Hohman 1986). Various bird species have 

been reported to abandon their nests after being exposed to ground-based and 
14 CERL TR 00-13 

aerial disturbances. White and Thurow (1985) reported that approximately 30 

percent of Ferruginous Hawks (Buteo regalis) abandoned their nests after being 

exposed to various ground-based disturbances, but there were no controls for 

comparison. Anderson et al. (1989) reported that 2 of 29 Red-tailed Hawk nests 

were abandoned after being flushed by helicopter flights, compared with 0 of 12 

control nests. Ellis et al. (1991) found only 1 of 19 Prairie Falcon (Falco mexicanus) nests were abandoned when exposed to frequent low-altitude jet flights 

during the nesting season (no control sites used). Platt (1977) reported similar 

rates with only 1 of 11 Gyrfalcon (F. rusticolus) nests failing (reportedly due to 

snow damage), compared with 0 of 12 control nests. Of the 6 Peregrine Falcon 

(F. Peregrinus) nests exposed to helicopter flights, only 1 was abandoned (also 

apparently due to inclement weather) compared with 0 of 3 control sites (Windsor 1977). 

Birds may be more susceptible to disturbance-caused nest abandonment early in 

the nesting season, possibly because parents have less energy invested in the 

nesting process (Knight and Temple 1986). Some animals appear reluctant to 

leave the nest later in the nesting season (Anderson et al. 1989; Ellis et al. 1991; 

Delaney et al. 1999). Steenhof and Kochert (1982) reported that Golden Eagles 

(Aquila chrysaetos) and Red-tailed Hawks exposed to human intrusions during 

early incubation had significantly lower nesting success than individuals exposed later in the season (45 percent success for Golden Eagles and 57 percent 

for Red-tailed Hawks within experimental groups versus 71 percent and 74 percent success with control groups, respectively). Although reactions of adult birds 

at the nest can influence hatching rates and fledgling success (Windsor 1977), 

flush behavior of adult birds from the nest is poorly quantified (Fraser et al. 

1985; Holthuijzen et al. 1990; Delaney et al. 1999). In the few studies that have 

examined bird responses to specific disturbance types (e.g., aircraft approach distance), flush rates were higher if birds were naive (i.e., not previously exposed; 

Platt 1977). Some birds are more reluctant to flush off the nest during incubation and early nestling phases than later in the season (Grubb and Bowerman 

1997; Delaney et al. 1999). Animal responsiveness has been shown to increase 

as the nesting season progresses (Grubb and Bowerman 1997). Delaney et al. 

(1999) found that Mexican Spotted Owls were more responsive to helicopters 

later in the reproductive cycle, which suggests that adult defensive behavior may 

decrease as the young mature. In contrast, Holthuijzen et al. (1990) found Prairie Falcon responsiveness to nearby blasting activity decreased as the nesting 

season progressed. 

Few studies have documented the threshold distance that causes birds to flush 

in response to noise disturbance events. In those studies that reported stimulus 

distance, it was rare for birds to flush when the stimulus distance was greater 
CERL TR 00-13 15 

than 60 m (Carrier and Melquist 1976; Edwards et al. 1979; Craig and Craig 

1984; Delaney et al. 1999). Similar findings were reported by Carrier and 

Melquist (1976) for Osprey (Pandion haliaetus), and Ellis (1981) for Peregrine 

Falcons. Many disturbance study reports imply that animal response increases 

with decreasing stimulus distance (Platt 1977; Grubb and King 1991; McGarigal 

et al. 1991; Stalmaster and Kaiser 1997), though only a few studies have experimentally tested this relationship (Delaney et al. 1999; Pater et al. 1999). 

Delaney et al. (1999) found that the proportion of owls flushing in response to a 

disturbance was strongly and negatively related to stimulus distance and positively related to noise level. Pater et al. (1999) found similar results when they 

experimentally exposed Red-cockaded Woodpeckers to military training noise. 

Even fewer examples are available for noise response thresholds. Snyder et al. 

(1978) reported that Snail Kites (Rostrhamus sociabilis) did not flush even when 

noise levels were up to 105 decibels, A-weighted (dBA) from commercial jet traffic. This result was qualified by the fact that test birds were living near airports 

and may have habituated to the noise. Edwards et al. (1979) found a doseresponse relationship for flush responses of several species of gallinaceous birds 

when approach distances were between 30 and 60 m and noise levels approximated 95 dBA. Delaney et al. (1999) reported that Mexican Spotted Owls did not 

flush during the nesting season when the sound exposure level (SEL) for helicopters was ≤ 92 dBA and the Equivalent Average Sound Level (LEQ) for chain saws 

was ≤ 46 dBA. Noise response thresholds were fairly comparable with data from 

the nonnesting season (SEL of 92 dBA for helicopters and LEQ of 51 dBA for 

chain saws). 

Distance has been described as the most commonly used surrogate for noise disturbance in the literature on animal response to noise, and has been proposed to 

be the best representative for quantifying the relationship between stimulus and 

response measures (Awbrey and Bowles 1990). The reason appears to be that 

distance is more conveniently implemented into management practices (i.e., establishing buffer zones) than other variables. However, use of a properly measured noise level as the stimulus measure facilitates broader application of response results, in particular to sources of similar aural character but different 

acoustic power emission.

3 Technical Approach 

Null Hypotheses 

Data collection, summary, and statistical analyses to assess and characterize 

military training noise in RCW clusters, and to evaluate the relationship between noise levels and RCW demographic data, are based on the following formal null hypotheses: 

• Ho: There is no difference in the nesting success, productivity, or nesting 

behavior between disturbed and undisturbed RCW nest sites. 

• Ho: There is no relationship between stimulus distance or noise level and 

RCW response behavior. 

• Ho: There is no difference in RCW response between types of training activities. 

Study Area 

Fort Stewart is located in southeast Georgia (Figure 2), within Liberty, Long, 

Bryon, Tattnall, and Evans counties, and is the largest Army Installation east of 

the Mississippi River. Physiographically, this area lies within the Atlantic 

Coastal Flatwoods Province, within a humid, semi-tropical latitude, and averages 50 in. (127 cm) of rain per year. The average temperature in January is 62 

°F (44 °C) with a relative humidity of 70 percent, while July averages 91 °F (32 

°C) with a relative humidity of 76 percent. Approximately 66 percent of the 

112,745 ha of the installation are terrestrial and cover three main forest types: 

upland pine stands composed primarily of longleaf (Pinus palustris), loblolly (P. 

taeda), and slash pine (P. elliottii); mixed pine-hardwood sites; and hardwood 

stands. The remaining habitats include various wetland types and open water 

(Fort Stewart ESMP Team 1998). 

The primary mission of Fort Stewart is training and operational readiness of the 

3rd Infantry Division (Mech.) and other nondivision units. The 3rd Infantry Division (previously the 24th) was activated in 1975 and redesignated as a mechanized division in 1979 (Hayden 1997). Training activities are conducted yearround at Fort Stewart to maintain a combat ready fighting force. The installa-
CERL TR 00-13 17 

tion also supports training of regional National Guard and Reserve units, as well 

as joint training exercises with troops from other installations and DoD 

Branches (Fort Stewart ESMP Team 1998). 

Figure 2. Location of Fort Stewart within the state of 

Georgia.

Fort Stewart contains a variety of impact and firing areas (Figure 3). The central feature of the installation is the Artillery Impact Area (AIA; about 5,200 ha), 

which is surrounded by dozens of artillery firing points varying in distance from 

a few hundred meters to thousands of meters from the impact area. On the 

western border of the AIA is the Red Cloud Multipurpose Range Complex 

(MPRC) containing eight separate ranges. Just south of the AIA is the Explosive 

Ordnance Disposal Area (EOD), the Demolition Area (DEMO), and the Small 

Arms Impact Area (13 live-fire ranges, about 2,300 ha). To the east and northeast of the AIA are the Calfax and Luzon Ranges, and three smaller Aerial Gunnery Ranges (AGRs). There are also seven drop zones located throughout the 

installation (Hayden 1997). 

Sample Cluster Selection 

There are 294 known RCW clusters distributed across Fort Stewart (Figure 3). 

None are known to be in the AIA because this area has not been surveyed due to 

safety concerns. Of the approximately 165 reproductively active (mated pair 

present) RCW clusters in 1999, we chose 48 sample clusters for experimentation 

during the second field season. This was a substantial increase over 1998 for 
18 CERL TR 00-13 

which we were able to collect experimental data at only four sample clusters (Pater et al. 1999). We intend to use these same clusters insofar as practical 

throughout this multiyear study. We classified clusters according to type and 

level of training noise, based on the number, distance, and noise levels of stimulus events that each cluster typically receives. Three types of sample sites were 

chosen: passive disturbed, undisturbed, and experimental. “Passive disturbed”

sites were those sites that received potentially significant noise disturbance as 

part of normal training operations; we had no direct control over time, number, 

or level of noise events at these sites. Noise types include large-caliber live fire, 

small arms live fire, grenade and artillery simulators, and helicopter flights. We 

attempted to choose sites that received predominantly one type of noise, but this 

was sometimes impossible if we were to also use the highest noise level clusters. 

“Undisturbed” or “low disturbance” sites (the two terms are equivalent and are 

used interchangeably in this report) are sites where noise levels were judged 

likely to be consistently low or absent for all of the noise types. At these sites we 

observed behavior and measured success as a baseline for judging impact at disturbed sites. It is likely that at least some level of military noise of some type 

can be perceived at every RCW cluster on Fort Stewart. Our criterion for low 

disturbance is noise levels at or near ambient noise levels. At “experimental”

sites we exposed birds to either artillery simulators (Figure 4) or .50-caliber 

blank fire (Figure 5) under controlled conditions at distances of 15.2, 30.5, 61, 

Figure 3. Locations of training areas and RCW clusters on Fort Stewart. 
CERL TR 00-13 19 

76.2, 91.5, 122, and 244 m from the nest tree (Appendix B, Tables B1 and B2). 

Not all distances were tested for each noise source because bird response dictated which distances would be used for developing a distance-response threshold. The experimental sites were chosen from among cluster sites that had low 

to moderately low disturbance levels. This implies that birds at these sites were 

not habituated to the noise stimulus. Sample size was limited by the number of 

clusters that fit each of the foregoing selection protocol criteria and by available 

field observation resources. 

Impact Measures 

Selection of noise impact criteria is a critical issue. For humans the response 

criterion is typically annoyance. For domesticated species the issue may be 

damage to individual animals or impacts on profits. For TES, the ultimate concern is long-term survival of the species. The challenge is to develop a relatively 

short-term procedure for inferring impact on long-term survival. The conceptual 

approach used in this study is depicted in Figure 6. First, proximate responses 

to the noise stimulus are measured. A proximate response is the direct and immediate response of the animal to the stimulus; for example a behavioral (e.g., 

flight) or a physiological (e.g., change in heart rate) response. This tracks with 

the first regulatory decision criterion of the Endangered Species Act (ESA), that 

is, whether the action or activity “may affect” the species. Next, we examine 

whether the stimulus that elicited the proximate response affects “individual fitness,” which is typically evaluated in terms of adult and juvenile mortality or 

Figure 5. Artillery simulator blast. Figure 4. .50-caliber machine gun. 
20 CERL TR 00-13 

reduced nesting success. Mortality and nesting success are established by field 

monitoring of many individuals throughout the nesting season. This level of effect tracks with the next decision criterion of the ESA, namely whether the action or activity is “likely to jeopardize the continued existence” of the species. 

Population effects will be inferred from measures of individual fitness by application of population viability analysis (PVA) models. Current applications of 

PVA do not capture the temporal and spatial variability of training events, and 

thus cannot model the resulting effects on endangered species’ demographic parameters. Researchers at the Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC/CERL) currently are developing PVA modeling approaches capable of capturing training effects in predictive 

population models. This is a shared effort under this project and a related 

ERDC/CERL research effort to evaluate effects of maneuver training (vehicles 

and troops) on RCWs. 

In summary, the research paradigm is that proximate effects can be linked to 

individual fitness, which in turn can be linked to population effects. As a specific 

example, consider that a bird might flush from a nest (a proximate response) in 

response to a noise event. It is possible that this could lead to failure of the nest, 

especially if the noise and flush response occurred repeatedly. Monitoring is required to determine nesting success of disturbed and undisturbed nests. A population model is required to determine if such failure of some percentage of nests 

has an effect on survival of the population.

Behavior and Proximate Response Measurement Protocols 

We documented woodpecker behavior at low and high noise disturbance nest 

sites by direct observation (camouflaged blinds more than 30 m from the nest) 

and through video surveillance. We divided the nesting cycle into three stages: 

incubation (eggs present 0 to 11 days), brooding (small chicks attended by adults: 

days 12 through 22), and nestling (larger chicks typically unattended in nest: 

day 23 until fledging). A “data session” consisted of behavioral observations of at 

least one adult RCW, typically for 1 hour or longer. At disturbed sites we attempted to observe behavior for some period of time before and after each noise 

event. This was sometimes not possible at passive disturbed sites because noise 

events were so frequent that we could not document undisturbed behavior for 

extended periods of time. 

To evaluate RCW baseline behavior and responses to military training activities, 

we measured several parameters: 

1. Alert — RCW moves to the cavity mouth, head movements, orient to noise 

source; 

2. Flush from nest — RCW departs from the nest in response to the stimulus, and 

remains away from the nest for a measured period of time; 

3. Recovery time — length of time an adult is away from the nest after being 

flushed; 

4. Nest attentiveness — proportion of time that the adults spend on the nest 

through the nesting season (calculated for diurnal, 24-hour periods, and for each 

nesting phase); 

5. Prey deliveries — number and rate of prey deliveries to the nest; 

6. Trips — number and duration of times the attending adult left the nest. 

RCW behavior categories 4 through 6 will be presented in a future report after 

the data have been fully analyzed. 

Demographic and Nesting Success Data 

RCW demographic data (population size, growth, density, and distribution) were 

collected in accordance with established protocols used by the Fish and Wildlife 

Branch DPW on Fort Stewart. Demographic data included the following parameters for each cluster: 
22 CERL TR 00-13 

1. Cluster occupancy — cluster occupied by one or more RCWs. Most individuals 

are identified by unique leg band combinations (provides a measure of population 

size, growth, and stability); 

2. Mated status — presence of both an adult male and an adult female RCW; 

3. Active nest — at least one egg was laid; 

4. Nesting success — at least one fledgling was produced (provides a measure of the 

proportion of RCW clusters that are reproductively successful); 

5. Nesting productivity — number of young fledged per nest (provides a measure of 

fecundity); 

6. Number of eggs produced; 

7. Number of nestlings hatched; 

8. Group size — (provides a possible measure of territory quality and availability). 

These data enable several trends to be detected: 

1. Reproductive loss — mortality rate of eggs, nestlings, and fledglings during nesting; 

2. Annual nest reoccupancy rates — provides a potential measure of RCW response 

to disturbance. Sites with heavy disturbance levels may be abandoned in subsequent years in favor of other sites further from specific disturbances; 

3. Site tenacity — turnover rate of adult and helper RCWs within a cluster site 

across years; 

4. Nesting success rates at disturbed and undisturbed sites; 

5. Mean number of young fledged at disturbed and undisturbed sites; 

6. Mean clutch and brood size at disturbed and undisturbed sites; 

7. Reproductive potential — total number of young that could be produced if all 

eggs and nestlings survived to fledge successfully. 

Most of the demographic data for Red-cockaded Woodpecker clusters was collected by DPW Fish and Wildlife personnel from Fort Stewart. Each active (at 

least one RCW present) cluster was initially visited to determine the cluster occupancy. Adult RCWs were banded to determine group size and affiliation using 

methods similar to Walters et al. (1988). A 25 percent random sample of all RCW 

clusters were then monitored approximately every 7 to 9 days to record clutch 

and brood size. Nestlings were uniquely color banded approximately 5 to 10 

days after hatching. Clusters were visited 20 to 25 days after nestlings were 

banded to determine the number and sex of fledglings (Walters et al. 1988). The 

25 percent sample included many of our sample clusters. We augmented the 

DPW Fish and Wildlife sample by monitoring demographic data (particularly the 

number of young fledged) for additional cluster sites to provide more complete 

coverage of our sample clusters. 
CERL TR 00-13 23 

Video Surveillance 

Video cameras are being used as a means to record RCW behavior over prolonged 

periods, to reduce costs, and to avoid potentially disruptive effects of human 

presence. The camera systems can also be used to document response in areas 

that cannot be safely monitored (e.g., downrange from firing positions). Cameras 

were attached to tree trunks with adjustable, jointed angle-brackets and screws. 

Cameras were mounted at the same level or slightly above nest height in the 

nearest practical tree and at least 5 m from the nest tree so as not to disturb incubating woodpeckers. Power and coaxial cables were covered with camouflaged 

cloth and were attached to a 10.5-cm, DC (direct current) monitor and battery so 

camera placement could be directed from the base of the camera tree. At least 

two people are required for camera placement: a climber to position the camera 

and a person on the ground to check the video signal and placement. Then, a 

trunk line is attached at the base of the tree (covered by a camouflaged 1.2-cm 

diameter hose for protection against rodents), allowing the power/recording station to be placed 60 m from the tree to minimize potential disturbance to the 

woodpeckers. We put the recorder, twin batteries, and all connectors inside a 

weatherproof bin concealed under a camouflaged tarpaulin. Freshly recharged 

batteries are used for each set of recordings. We used charge-coupled device 

(CCD) video-board cameras (both black and white and color) to document RCW 

behavior at 8 nest sites during the 1999 nesting season. The solid state, 12-volt, 

flexible circuit-board black and white cameras were equipped with 12.0-mm 

lenses, while the color cameras had 75-mm lenses. The cameras provide a minimum of 380 lines of resolution and have a minimum sensitivity of 0.45 Lux. 

Black and white cameras are mounted in waterproof heavy-gauge plastic switch 

boxes with transparent covers (12.9 x 6.7 x 4.1 cm) which, except for the lens and 

LED (light-emitting diode) area, are painted black. Color cameras were housed 

in metal weatherproof containers. Two ports are threaded into the protective 

housing: one for the power supply and the second for the video signal (Delaney, 

Grubb, and Garcelon 1998). Panasonic Model AG-1070DC Professional/ Industrial VHS video recorders, connected to cameras via coaxial cable (RG-59), provided approximately 24 hours of coverage per tape. These 12-volt, DC-powered 

recorders were designed for surveillance applications. Cameras and video recorders are powered by two 12-volt, 33.0-amp-hour, Power-Sonic Model PS-12330 

sealed rechargeable batteries connected in parallel (a 24-hour taping would draw 

a single battery below operational limits). These “gel-cell” type batteries (weighing 11.3 kg each) reduce the risk of battery damage, and eliminate the potential 

for spillage during backpack transport. 
24 CERL TR 00-13 

Sound Instrumentation and Recording 

Sony TCD-D7, Digital Audio Tape (DAT) recorders were used to continuously record all noise events, along with the exact time and date. We attached Bruel & 

Kjaer (B&K) Type 4149 1.3-cm Condenser Microphones with 7.5-cm wind screens 

to B&K Model 2639 Preamplifiers, mounting the microphone on a 1-m stick, and 

placing the unit directly under a woodpecker’s nest about 1-m from the tree 

trunk. The power supply and DAT recorder were also placed at the base of the 

nest tree in a small camouflaged container. A 1.0-kHz, 94-dB calibration signal 

(20 micropascals reference) from a B&K Type 4250 Sound Level Calibrating System was recorded before and after each noise event recording. This signal provides a reference for sound levels and spectra when data are later analyzed using 

a B&K Type 2144 Frequency Analyzer. All noise data were analyzed at ERDC/ 

CERL. In addition to recording noise levels at the base of the nest tree, we also 

recorded noise levels within nest cavities during the postnesting season and at 

nonnesting sites. 

Sound Metrics 

Noise is defined as sound that is undesirable or constitutes an unwarranted disturbance, and can alter behavior or normal functioning (ANSI S1.1-1994). The 

types of military noise that are within the scope of this study vary widely in instantaneous transient amplitude, duration, spectral energy content, and suddenness of onset. Appropriate noise metrics and frequency weighting are essential 

to adequately quantify noise impact for each type of noise. Noise metrics are 

chosen to measure the noise dose in a way that meaningfully correlates with subject response. Frequency weighting is an algorithm of frequency-dependent attenuation that simulates the hearing sensitivity and range of the study subjects. 

Frequency weighting discriminates against sound that, while easily measured, is 

not heard by the study subjects. The current project requires specialized metrics 

and techniques to meaningfully measure noise impacts on animals. Our paradigm is to measure noise events in terms of unweighted one-third-octave-band 

levels, apply frequency weighting to the resultant spectra, and calculated appropriate overall metrics. 

Only noise that is audible to the study species should be accounted for in the 

metric used to quantify noise level. Frequency weighting designed for humans 

may not be appropriate for animal species. The commonly used “A” frequency 

weighting (ANSI S1.4-1983) attenuates noise energy according to human hearing 

range and sensitivity. For human response to blast noise, “C” frequency weighting is often applied to received blast noise signals, rather than “A” weighting 
CERL TR 00-13 25 

which is more representative of human hearing response (ANSI S1.4-1983). This 

is done to retain low frequency energy that, while not heard by humans, causes a 

secondary rattle in buildings which does evoke response (ANSI S12.4-1986). 

This is not appropriate for wildlife. An audiogram, which describes hearing 

range and sensitivity, provides guidance regarding appropriate frequency 

weighting for the species of interest and also aids in interpretation of noise response data. Figure 7 shows a composite average audiogram of seven orders of 

birds, with an approximate representation of a human audiogram and the “A”

weighting curve included for comparison. The differences are substantial. The 

“owl” audiogram further illustrates how audiograms can vary among species. 

We searched the literature and consulted several leading experts on bird hearing 

without finding an audiogram for the RCW or for any species in RCW’s order, 

Piciformes. Thus, as part of this project we will obtain an audiogram that will be 

used to develop a frequency weighting function that is appropriate for woodpeckers. Information on the current RCW audiogram work can be found in Pater et 

al. (1999). It is well-established (ANSI S12.40-1990; S12.9-1996; S12.17-1996; 

Homans 1974; NAS 1977, 1981; Rice 1983; Rice et al. 1986; Schomer et al. 1994) 

that the appropriate metric for blast noise is SEL, which is essentially the time 

integral of the square of the acoustic pressure. We measured blast noise as unweighted 1/3-octave band SEL, to which frequency weighting appropriate for the 

RCW will be applied (when available from the audiogram portion of this study, 

described in Appendix B) to obtain appropriately weighted overall levels. The 

same metric and procedure was also used with small arms noise (Buchta 1990; 

Hede and Bullen 1982; Hoffman et al. 1985; Luz 1982; Sorenson and Magnusson 

1979; Vos 1995). Two metrics, the SEL and the maximum 1-second equivalent 

average (LEQ) level, were used for helicopter noise, airplane noise, and vehicle 

pass-by noise, since both are meaningful in terms of correlation with response 

(Environmental Protection Agency [EPA] 1974, 1982; Federal Interagency Committee on Urban Noise [FICUN] 1980; Fidell et al. 1991; Schomer 1994; Schultz 

1978; U.S. Code of Federal Regulations 1980). Ambient noise was measured as 

LEQ for various appropriate time periods (EPA 1982). In all cases, the noise signals were recorded on digital audio tapes and preserved for possible further 

analysis.

Statistical Data Analysis 

We used SPSS 8.0 for Windows (SPSS Inc. 1998) to perform all descriptive statistics; for example, one-way ANOVA for comparing the mean number of eggs, nestlings, and young fledged between the first through third nesting attempts. Independent sample t-tests were used to compare nest productivity data between 

experimental and control sites. Whenever appropriate, multiple observations at 

single nests were averaged before inferential tests were performed so that the 

sample sizes are the number of nests examined. We used a one-tailed Fisher 

Exact Test to assess 2x2 contingency tables for variability in nesting success between disturbed and undisturbed nest sites (Zar 1984). Alpha levels of 0.05 will 

be required to reject a null hypothesis for all tests. Means ± standard error (SE) 

are presented throughout this document.

4 Results 

Initiation Dates for each Nesting Phase 

The first woodpecker clutches were initiated on approximately 13 April through 

16 May, while secondary clutches (clusters that renested after initial nest failure) were initiated on 3 May through 14 June. Third clutches were initiated on 

16 May through 23. Eggs from initial nesting attempts hatched on approximately 23 April through 26 May, while nests from second nesting attempts 

hatched on 13 May through 24 June. Third nesting attempts hatched on approximately 5 June through 3 July. We observed young fledging from initial 

nesting attempts on 22 May through 21 June, and from 8 June through 20 July 

for fledglings from secondary nesting attempts. Third nesting attempts fledged 

on approximately 21 June through 9 July. 

Overall Population Dynamics 

Of the 198 potential breeding pairs on Fort Stewart, 165 nested during the 1999 

nesting season (83.3 percent). This was a 20 percent increase over the number of 

potential breeding pairs (165) and a 17 percent increase in the number of clusters that nested (141) on Fort Stewart in 1998. Of the clusters that nested, 86.1 

percent fledged young successfully. Thirty-three of the 47 clusters that initially 

failed to nest were found renesting within the following 2 weeks, with 72.7 percent of these sites successfully fledging young. Clusters that renested were 

found to be as successful (Fisher Exact Test, P = 0.15; 72.7 percent for sites that 

renested versus 70.2 percent for initial nesting attempts) and productive as sites 

that nested only once. We observed no statistically significant difference in 

number of eggs (F2,200 = 0.98, P = 0.38), nestlings (F2,202 = 0.64, P = 0.53), or the 

number of young fledged (F2,199 = 1.20, P = 0.30) between sites that renested and 

those that nested only once. We then pooled these data to determine mean rates 

for the overall population. Mean clutch size for RCW nests was 2.75 ± 0.07 

eggs/nest; mean brood size was 2.22 ± 0.07 nestlings/nest; and the number of 

young fledged was 1.76 ± 0.08 young/occupied nest (2.04 ± 0.07 young/successful 

nest). Occupied nests include sites that are successful as well as sites that are 

not. Successful nests include only those sites that are successful in fledging 

young. Approximately 290 young fledged from RCW nest sites during 1999, with 
28 CERL TR 00-13 

53.0 percent of those young being male. There was a 35.9 percent decline in the 

reproductive potential of RCW nests from the incubation phase to the nestling 

phase (P < 0.001). The decline was not as dramatic from the nestling phase to 

the fledgling phase (16.9 percent), but was still significant (P = 0.04). Overall, 

we observed a significant decline of 53.2 percent in the reproductive potential 

from incubation through the fledgling phase (F2,492 = 61.8, P < 0.001). Of the 23 

clusters that failed to produce young during 1999, it appears as if at least one 

site failed due to nest predation by a rat snake (Elaphe obsoleta), while a second 

nest may have been lost to southern flying squirrels (Glaucomys volans). In another case, a rat snake was taken by Fort Stewart Fish and Wildlife personnel 

from a cluster that had produced a second clutch. The snake later passed identification bands for the young of that cluster confirming that it had consumed the 

nestlings. Two other sites had partial brood loss due to flooding of the nest cavity. 

Sample Cluster Population Dynamics 

As was the case for the population as a whole, the project sample clusters that 

renested after initial nest failure were as successful and productive as sites that 

nested only once. Therefore, data were pooled before determining overall sample 

group fitness rates. Disturbed and undisturbed nest sites did not differ significantly in the number of eggs (F1,72 = 1.65, P = 0.20), number of nestlings (F1,72 = 

3.52, P = 0.07), or number of young fledged (F1,72 = 3.09, P = 0.08). Forty-two of 

the 48 disturbed RCW nest sites were successful in producing an average of 3.47 

± 0.16 eggs/nest, 2.27 ± 0.16 nestlings/nest, and 1.84 ± 0.16 young/occupied nest 

(2.14 ± 0.14 young/successful nest), while 23 of 25 undisturbed sites were successful in producing an average of 3.56 ± 0.31 eggs/nest, 2.28 ± 0.17 nestling/nest, and 1.80 ± 0.17 young/occupied nest (1.96 ± 0.15 young/successful 

nest). The number of disturbed sites that successfully nested was not significantly different from undisturbed sites (Fisher Exact Test, P > 0.05). For disturbed sites, 8 of the 48 nesting attempts were second attempts. One disturbed 

site produced and successfully fledged a second clutch, though experimental testing was only done during the first clutch. For undisturbed sites, 8 of 25 nesting 

attempts were second attempts. The number of disturbed cluster sites that renested was not significantly different from undisturbed sites (Fisher Exact Test, 

P > 0.05). One undisturbed site attempted to nest for a third time, but did not 

successfully fledge young. We found no difference in the reproductive success 

(Fisher Exact Test, P > 0.05) or productivity (F1,47 = 2.49, P = 0.12) for RCW cluster sites exposed with artillery simulator blast noise versus sites that received 

.50-caliber blank fire.

Noise and Response Monitoring Summary 

During the 1999 field season we documented RCW response to experimental 

noise from controlled artillery simulators and .50-caliber blank fire. Passive 

noise from large-caliber live fire (25-mm M2A2 Bradley Fighting Vehicles, 120-

mm M1A1-Tanks, and 155-mm M109 Howitzers), grenade simulators, smallarms live fire (5.56 mm M-16 and Saw, 7.62-mm, and .50-caliber machine guns), 

and military helicopters was recorded as it occurred. Passive noise was monitored during all nesting phases, while experimental tests were performed only 

during the incubation and early portions of the brooding phase when adults were 

present at the nest for extended periods of time. 

We made noise measurements and behavioral response observations at a total of 

48 experimental and 14 passive sample clusters (9 of the 14 passive sample clusters were also used in experimental testing). Detailed results are described below and are presented in the data tables and figures in Appendices B, C, and D. 

The tables of Appendix B present summaries of the noise level measurements 

and RCW responses. A typical spectrum for the most prevalent noise sources is 

presented in Appendix C. Appendix D presents noise level summaries for each 

noise stimulus type and detailed noise measurements in terms of one-thirdoctave-band SEL levels. These are the data to which future adjustments for cavity resonance and woodpecker frequency weighting will be applied to obtain single-number overall noise levels. We also made behavioral observations at a total 

of 25 undisturbed sample clusters for the purpose of obtaining a baseline against 

which to judge proximate response at the disturbed clusters. 

Passive Monitoring 

We recorded 691 passive noise events in 34 data sessions at 14 RCW clusters 

during the 1999 nesting season. Small-arms live fire events (M-16 rifles) were 

recorded most frequently, followed by large-caliber live fire events (greater than 

20 mm in diameter), helicopters, and grenade simulators. Multiple noise events 

and stimulus types were usually recorded during each data session. Stimulus 

type, frequency, and noise level varied for each cluster and are shown in the tables of Appendix B.

Experimental Testing 

We conducted 105 experimental tests at 48 cluster sites (24 for each noise type) 

during the 1999 nesting season (Tables B1 and B2, Appendix B). 
30 CERL TR 00-13 

Noise Measurement Testing 

In addition to recording noise levels at the base of active RCW nest sites, we also 

measured noise levels in nest cavities before or after the nesting season. Both 

natural and artificial cavities were tested in 1999. Nest cavities were found to 

act as sound resonators, emphasizing the 125 to 250-Hz portion of the frequency 

band, and varying by individual tree. In the examples presented in Figures C1 

and C2 (Appendix C), artillery simulators and .50-caliber blank fire events had 

maximum spectral noise levels 13 and 13.1 dB louder, respectively, inside the 

nest cavity compared with recordings for the same events measured at the base 

of the nest tree. 

Distance and Noise Level Thresholds for Response

Experimental Tests 

Artillery Simulators 

As stimulus distance decreased, RCWs flush frequency increased (Figure 8), regardless of stimulus type (Tables B1 and B2). RCWs did not flush when artillery 

simulator blasts were > 244 m away from nest sites and SEL noise levels < 84 

dBA (89 dB, unweighted). Only one flush response was documented at a distance of 122 m. RCWs returned to their nests on average within 4.6 minutes after being flushed, while returning no later than 10 minutes overall (Figure 9). 

Data collection during the 2000 field season will emphasize the distance between 

122 and 244 m to better develop the distance and noise thresholds for RCW response, as well as replicate those distances tested during the 1999 season. 

.50-Caliber Blank Fire 

Similarly, we only recorded one flush response due to .50-caliber blank fire at 

122 m. We attempted to test RCW response to .50-caliber blank fire at distances 

> 122 m, but due to weather and other logistical constraints we were not able to 

develop a distance-response threshold for the cluster that flushed at 122 m. 

Data collection during the 2000 field season will emphasize this distance. Blank 

fire testing consistently elicited higher response rates than artillery simulators 

at similar distances (Figure 8). At distances < 122 m, .50-caliber blank fire elicited a significantly greater flush response (49.1 percent) than comparably distance artillery simulators (31.3 percent; Fisher’s Exact Test: P < 0.05, Appendix 

B: Tables B1 and B2). 
CERL TR 00-13 31 

Figure 8. RCW flush frequency by stimulus type and distance. 

RCWs flushed only once when .50-caliber blanks were fired at distances of 122 m 

from nest sites and did not flush when SEL noise levels were < 72 dBA (82 dB, 

unweighted). Ambient sound levels were substantially lower than experimental 

noise events during all tests. On average, RCWs returned to their nests within 

6.3 minutes after being flushed (within 12 minutes overall; Figure 9). Data collection during the 2000 field season will emphasize areas greater than 122 m to 

develop the distance and noise thresholds for RCW response, as well as replicate 

those distances tested during the 1999 season.

Passive Events 

Small-Caliber Live Fire 

There was only one RCW nest site, cluster 103, that received small-caliber live 

fire noise at distances less than 400 m. Noise levels at cluster 103 were louder 

than other clusters due to supersonic bullet noise (“sonic boom”) and ricocheting 

bullets from an M-16 range (Small Arms — Golf) hitting trees in close proximity 

to the nest tree. The two other clusters monitored for passive noise in the Small 

Arms Impact Area (clusters 3 and 25) were between ranges and much further

downrange than cluster 103 and therefore received lower noise levels. These 

sites were monitored remotely during firing periods via video camera and audio 

recording equipment. 

RCWs did not appear to flush in response to small-caliber noise at cluster 103, 

but their flight activities may have been influenced. On 3 separate days, over a 

6-day period, RCWs were only observed arriving and departing from the nest 

during inactive periods at the range (Figures 10 through 12). Data points for 

Figures 10 through 12 represent individual bullet noise events or groups of muzzle blast events that were separated in time from other shots. Red lines represent times when RCWs returned to the nest and blue lines represent times that 

birds departed the nest. Noise levels from bullet “sonic booms” and ricocheting 

bullets were substantially louder than rifle muzzle noise coming from the range 

(Figure 13). Further analysis will reveal whether the “bullet noise” is due to 

sonic booms and/or bullets impacting trees. When we compared the frequency 

spectra for muzzle blast noise versus bullet noise we found that most of the noise 

energy for muzzle blast noise occurred at 630 Hz, while the bullet noise occurred 

at higher frequency levels, around 1600 to 2000 Hz. Bullet noise is identified on 

Figures 10 through 12 by the similarities between the unweighted and “A”

weighted noise levels, and account for all data points above 78 dB. “A” weighted 

noise levels were very close to their corresponding unweighted noise levels. Bullet noise reached levels 30 dB louder than muzzle blast noise within the 1600 to 

2000 Hz range and around 15 dB louder when peak levels for both noise events 

were compared (Figure 13). Bullet noise represented 15.6 percent (102 noise 

events, Table B3) of the noise events that were documented at cluster 103. Cluster 103 successfully fledged two young in 1999. 

Overall, RCWs did not flush when small-arms live fire was more than 400 m 

from active nest sites and SEL noise levels were < 77 dBA (79 dB, unweighted; 

Appendix B, Table B3). Small-arms live fire events < 100 m did not represent 

shots from rifles themselves, but were from bullet noise. We were not able to determine the exact distances that bullets were hitting surrounding trees, but due 
CERL TR 00-13 33 

to the received noise levels and the fact that we have seen bullets lodged in 

nearby trees, distances appear to be relatively close. Rifle noise from Small 

Arms — Golf M-16 range was approximately 430 m from the nest. We did not 

locate any other active RCW nest sites < 400 m from any small arms ranges to 

which we had access for testing purposes.

Grenade Simulators 

RCWs flushed once during eight grenade simulator blasts recorded during passive noise events. This flush event occurred during a realistic training maneuver 

when a grenade simulator was detonated approximately 100 m from the nest 

(Figure C3, Appendix C). A bird was observed returning to the nest within 8 

minutes after the flush had occurred (this site was successful in fledging one 

young). Overall, RCWs did not flush when grenade simulators were detonated >

200 m from nest sites and SEL noise levels were < 84 dBA (91 dB, unweighted; 
36 CERL TR 00-13 
CERL TR 00-13 37 

Appendix B, Table B4). We did not record any grenade simulators < 100 m or 

between 100 and 200 m and therefore could not test for response within those 

ranges. 

Helicopters

RCWs did not flush when military helicopters were > 100 m from nest sites and 

SEL noise levels were < 88 dBA (104 dB, unweighted; Appendix B, Table B5). 

Due to the low probability of encountering helicopters, we were unable to test for 

RCW response at distances < 100 m. 

Large-Caliber Live Fire 

Large-caliber live fire events on Fort Stewart were dramatically reduced from 

numbers documented in 1998, therefore our ability to record RCW responses to 

such passive noise events was also limited. The 1999 field season data show that

RCWs did not flush when large-caliber guns were fired at distances > 700 m 

from nest sites and SEL noise levels were < 85 dBA (103 dB, unweighted; Appendix B, Table B6). We did not record any large-caliber gun fire < 700 m from 

any active RCW nest site, therefore, we could not test for response within that 

range.

5 Discussion 

Nesting Success 

The preliminary findings, based on 1999 experimental testing data, suggest that 

measured levels of training noise did not affect RCW nesting success or productivity. We believe the small but nonsignificant decrease in reproductive success 

between disturbed (N = 48) and undisturbed (N = 25) sites was attributable to 

natural attrition inherent in the larger disturbed sample. Through further investigation over the next year we will be able to make more definitive conclusions regarding RCW fitness as a function of training noise. 

Flush Response and Related Behaviors 

Flush Response 

The proportion of Red-cockaded Woodpeckers that flushed in response to experimental training noise was negatively related to stimulus distance. The doseresponse relationship for RCWs based on flush frequency with distance and 

noise level indicated that .50-caliber blank fire elicited a greater response than 

artillery stimulators. RCWs apparently perceive artillery simulators as less 

threatening than .50-caliber blank fire because of their shorter duration (total 

event duration), minimal visibility, and lessened association with human activity. 

It is possible that disturbances in closer proximity to an RCW’s location may also 

be more visible and therefore elicit a greater response than a disturbance farther 

away, regardless of noise level. It is important to consider all aspects of a stimuli 

when examining an animal’s response to a disturbance. Although season and 

nesting phase influence avian response to disturbance (Thiessen 1957; Knight 

and Temple 1986; Delaney et al. 1999), habituation, prior experience, and animal 

temperament are important factors that should be taken into account (Hart 

1985; Manci et al. 1988). 

RCWs flushed infrequently in response to passive military training noise during 

the 1999 nesting season. Most of the passive noise events that we recorded were 

distant and had relatively low noise levels. Woodpeckers returned to their nests 

relatively quickly after being flushed. Return times by RCWs were comparable 
CERL TR 00-13 39 

with times reported for bird species in other noise disturbance studies (Awbrey 

and Bowles 1990; Holthuijzen et al. 1990), and were comparable with 1998 RCW 

response data (Pater et al. 1999). The amount of time that an attending adult is 

away from the nest has important consequences when we consider the role that 

nest predation and nest competition has on this species. There are a number of 

species that are capable of usurping nesting cavities from the RCW. Both redbellied woodpeckers (Melanerpes carlinus) and red-headed woodpeckers (Melanerpes erythrocephalus) have been shown to remove and eat eggs, usually in the 

process of usurping the cavity from the RCW. Southern flying squirrels (Glaucomys volans) have also been documented to eat eggs or young when competing 

with RCWs for nest cavities (Jackson 1994). 

Nesting Behaviors 

Through audio and video surveillance it appears that noise from Small Arms —

Golf may have influenced RCW behavior at cluster 103 during the 1999 nesting 

season. RCWs were not observed arriving or departing from the nest during the 

nestling phase when the range was firing, only during inactive periods. It is possible that small arms fire from the range is influencing the timing, frequency, 

and duration of RCW flights from the nest. Noise levels for that range were 

louder than other comparably distant ranges due to the orientation of the rifles 

and because of bullet noise from sonic booms and ricocheting bullets. We are 

currently analyzing the remainder of the video data to determine if nest attentiveness, trip frequency, timing, and duration, or the number of prey deliveries 

are influenced by experimental or passive training activities on Fort Stewart. 

We did not observe any nest abandonment relative to camera use. Birds were 

observed using camera trees for foraging and perch sites when coming and going 

from the nest tree. 

Distance and Sound Thresholds 

Despite the aggressive nature of our testing regime (i.e., close proximity and repeated exposure), RCW behavioral responses were minimal when experimental 

stimuli were > 122 m away. We did not observe RCWs flushing from the nest 

when noise stimuli were > 244 m away. Stimulus distances > 122 m will be 

tested in more detail during the 2000 field season for the development of more 

definitive distance and sound thresholds based on RCW response parameters. A 

similar pattern was present during passive disturbances. We observed no flush 

responses by RCWs when passive stimuli were > 200 m away. Due to the varied 

nature and location of maneuver training activities on Fort Stewart, it is highly 
40 CERL TR 00-13 

unlikely that woodpeckers would receive as much disturbance activity during the 

nesting season within any year as the experimentally disturbed RCW sites received during this year’s study. 

An examination of the data presented in Appendices B and D reveals a wide 

range of received noise levels at a given distance. One reason is that different 

types of noise sources of course have different acoustic emissive power. For a 

given noise source, received noise level also depends on differences in propagation conditions, a result of differences in atmospheric wind and temperature 

structure. It is well known that at distances of several kilometers, received noise 

level can vary by as much as 20 dB above and below the mean due to changes in 

meteorological conditions (Embleton 1982; Li et al. 1994; Larsson and Israelsson 

1991; Pater 1981; Piercy et al. 1977; White and Gilbert 1989; White et al. 1993). 

Differences in received noise level can also be due to orientation of the weapon 

relative to the receiver. Many weapons exhibit substantial directivity; some as 

much as 15 dB louder downrange (Pater 1981; Pater et al. (DRAFT); Schomer et 

al. 1976a and 1976b [Vol I and II]; Schomer et al. 1979; Schomer et al. 1981; 

Schomer 1982; Schomer 1984; Schomer and Goebel 1985; Schomer 1986a, 1986b; 

Walther 1972). Some other important factors that should be taken into account 

are the orientation of the nest cavity relative to the noise source and any barriers 

between the noise source and the birds position. 

Noise Measurement Test 

Noise levels within RCW nest cavities were substantially louder than noise levels recorded at the base of the nest tree. Due to differences in cavity and weapon 

orientation, presence or absence of barriers, and weapon directivity, we were not 

able to extrapolate noise levels recorded at the base of the tree to received levels 

within RCW nest cavities. Noise measurements will therefore have to be taken 

inside each nest cavity before or after the nesting season for each noise source to 

determine the noise levels that birds may actually be experiencing. We will investigate this in more detail in 2000. We will also continue testing for differences between artificial and natural cavities during the 2000 field season. Data 

comparing natural and artificial cavities are currently being analyzed to determine if there is a variation in the resonant frequency of the nest trees and if 

there are any differences in the noise level or duration of the noise event from 

comparably distant stimulus events.

6 Plans and Conclusions 

Plans 

The results of the second year of this project have shown that the basic technical 

approach is appropriate and effective. The primary need is for more data, which 

we will collect during the 2000 field season by replicating the research protocol 

from 1999. In particular, we will obtain more data for experimental manipulations and passive disturbance events, such as small arms blanks, artillery, and 

helicopters. We will search for reproductively active clusters that are located in 

areas that will fill in the blanks in the data in terms of stimulus distance and 

noise level. 

The matter of cavity resonance effect on the noise level perceived by the RCWs 

will continue to be investigated. We cannot measure noise levels in the cavity 

being used by an endangered species during the nesting season; therefore, we 

will make cavity measurements during pre- and post-nesting periods. The investigation of woodpecker hearing is beginning to return useful results; the current 

effort will be continued. An expanded effort may be appropriate. 

One aspect of the technical approach that has not yet been executed is to use 

available noise models and training activity data to calculate noise dose for each 

cluster, and to examine these data for correlation with nesting success data. 

Fort Stewart installed the updated version of the Range Facility Management 

Support System (RFMSS) early in 1998. This system includes detailed data regarding training activity. These data will be used in 2000 to examine said correlation. 

Conclusions 

During the second year of this study of the impacts of training noise on the RCW, 

we observed and documented experimental training noise events and the resulting RCW responses under realistic conditions. We measured both proximate response behavior and nesting success. We also observed RCW behavior and nesting success at clusters where noise stimuli were absent or minimal (near or 

below ambient sound levels), to provide an undisturbed behavior baseline 
42 CERL TR 00-13 

against which to judge response and impact. No significant difference in nesting 

success was found between experimentally disturbed and relatively undisturbed 

nest sites. The second year data are limited in number and statistical power and 

are not sufficient to make strong conclusions or to establish reliable noise doseresponse relations or thresholds. The results are however sufficient to confirm 

that the project technical approach is appropriate and needs only minor revision, 

and that the project objectives will be achieved.

Appendix A: Significant Legal 

Requirements 

The Endangered Species Act (ESA) requires Federal agencies to carry out programs for the conservation of threatened and endangered species. Agencies are 

further required to ensure that their actions do not jeopardize the continued existence of listed species or result in the destruction or adverse modification of the 

critical habitat of these species. These requirements fall under provisions of Section 7 of the Act, which also requires agencies to conduct biological assessments 

to evaluate the impacts of their activities on listed species. This assessment 

serves as the primary basis for coordination with the U.S. Fish and Wildlife Service which, in turn, issues a biological opinion and specific endangered species 

management recommendations. Implementation of these recommendations can 

place constraints on execution of the military mission. To avoid possible penalties resulting from findings of “take” due to harassment or harm resulting from 

exposure to military-related noise, a capability is needed to evaluate and monitor 

the impact of noise on both behavior and breeding success of affected species. 

Under the ESA it is the responsibility of the land owner, not of the U.S. Fish and 

Wildlife Service, to evaluate effects of land use activities on threatened and 

endangered species. 

The ESA prohibits take of endangered species, where “take” means to harass, 

harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to 

engage in any such conduct. Within the definition of take, the term “harm” has 

been subject to significant judicial scrutiny. “Harm” is clearly an act that actually kills or injures wildlife, but it may also include actions that significantly impair essential behavioral patterns, including breeding, feeding, or sheltering. 

The National Environmental Policy Act (NEPA) requires Federal agencies to assess the impact of planned activities on the environment and to make the assessment available to the general public. The decision making procedures are 

documented by either an Environmental Assessment (EA) or an Environmental 

Impact Statement (EIS). Noise and threatened and endangered species are often 

important issues in these documents, particularly as reviewers place a stronger 

emphasis on cumulative effects of activities.

13. ABSTRACT (Maximum 200 words)

It is estimated that nearly a quarter of the remaining Red-cockaded Woodpecker (RCW) population resides on military 

installations in the southeastern United States. Such a close association has raised questions about the interaction between 

training and the conservation of Red-cockaded Woodpeckers on military land. Increased importance has been placed on 

determining how noise affects these species. This report presents second year results of a multiyear study to determine the 

effects of certain kinds of training noise on the endangered Red-cockaded Woodpecker. 

Preliminary data suggest that: measured levels of experimental noise from .50-caliber blank fire and artillery simulators did 

not affect RCW nesting success or productivity; Red-cockaded Woodpecker flush frequency increased as stimulus distance 

decreased, regardless of stimulus type; woodpeckers returned to their nests relatively quickly after being flushed; and noise 

levels in Red-cockaded Woodpecker nest cavities were substantially louder than levels recorded at the base of the nest tree.
