it is physically very similar to the other species of rock - rat , and differs mainly in skull characteristics . its habitat consists of rainforest and vine thickets in rocky sandstone gorges and escarpments .
although current threats are unknown it is thought that grazing by stock and feral herbivores may have contributed to the decline of the central rock - rat . feral predators ( cats and foxes ) could have a negative effect on the small , dispersed populations of the species . fire may have a limiting effect on the spread of the central rock - rat by limiting the availability of suitable habitat .
many arid zone mammals undergo large fluctuations in the size of their populations , usually associated with variations in rainfall . it is not unreasonable to assume that this is true for the central rock - rat .

the black rat is a complex pest , defined as one that influences the environment in both harmful and beneficial ways . in many cases , after the black rat is introduced into a new area , the population size of some native species declines or goes extinct . this is because the black rat is a good generalist with a wide dietary
trampling and grazing of sensitive vegetation by feral herbivores may also cause a decline in the habitat and abundance of carpentarian rock - rats .
the specific origin of the black rat is uncertain due to the rat ' s disappearance and reintroduction . evidence such as dna and bone fragments also suggests that rats did not originally come from europe , but migrated from southeast asia .

despite the central rock - rat having been described over 100 years ago , almost nothing is known about its life history or ecology . captive animals have bred and have had litters of 3 , 2 , 2 , 2 , 1 , 1 and 4 ( karen brisbane pers . comm . ) juveniles have been captured in the wild in june . dietary analysis performed on scats has shown the central rock - rat to be primarily granivorous with leaf , fern sporangia and insects being taken in smaller quantities ( jefferys 1998 ) .
the west macdonnell range national park has a fire management strategy in place to protect areas that contain rare plant species . this fire management strategy will help to protect the presumed refugia of the central rock - rat which generally correspond to areas containing rare plant assemblages .

, has been extirpated from many micro - habitats of australia . in the absence of a vector , the diversity of truffle species would be expected to decline . in a study in new south wales , australia it was found that although the bush rat consumes a diversity of truffle species , the black rat consumes as much of the diverse fungi as the natives and is an effective vector for spore dispersal . since the black rat now occupies many of the micro - habitats that were previously inhabited by the bush rat , the black rat plays an important ecological role in the dispersal of fungal spores . by eradicating the black rat populations in australia , the diversity of fungi would decline , potentially doing more harm than good .

poison control methods are effective in reducing rat populations to nonthreatening sizes , but rat populations often rebound to normal size within months . besides their highly adaptive foraging behavior and fast reproduction , the exact mechanisms for their rebound is unclear and are still being studied .
. the black rat shows preference for snails with larger shells ( greater than 10mm ) , and this led to a great decline in the population of snails with larger shells . a lack of prey refuges makes it more difficult for the snail to avoid the rat .

a fire management strategy developed to protect the rare plants , fire sensitive plant communities and fire shadow areas in the macdonnell ranges will be implemented to protect central rock - rat refugia . a fire management strategy such as this will not only protect central rock - rat habitat , it will also afford protection to other rare and fire sensitive plant communities and species which inhabit them e . g . common brushtail possums . any off - park fire management will require the permission of the landowner . the bushfires council of the northern territory will be available to facilitate off - park burning if this is required .

the black rat serves as prey to cats and owls in domestic settings . in less urban settings , rats are preyed upon by weasels , foxes , and coyotes . these predators have little effect on the control of the black rat population because black rats are agile and fast climbers . in addition to agility , the black rat also makes use of its keen sense of hearing to detect danger and quickly evade mammalian and avian predators .
until the 1996 capture , the central rock - rat had not been seen since 1960 when a single specimen was caught raiding a stockman ' s tuckerbox near mt liebig , . since that time several species - specific searches in the former locations and general fauna surveys had been conducted in the west macdonnell ranges without success .

based on the results of our village interview survey , 12 areas where local villagers have previously trapped the laotian rock rat were selected for targeted field surveys using cage traps and box traps . after taking morphological characters , all live - trapped animals were released back into the wild at the place where they were trapped . study of laotian rock rat habitat was carried out in the same 12 areas using transect survey and plot survey techniques . plots of 10 x 10 m were used for inventory of all trees with height more than 3m , plots of 4 x 4 m for inventory of bush trees of height from 0 . 5 m to 3 m , and plots of 1 x 1 m for inventory of herbs and tree seedlings less than 0 . 5 m high .
population modelling indicates that the population is highly sensitive to the frequency of hot , late dry - season fires , and these fires could lead to the rat’s extinction within 100 years .
found in south eastern , and west central colorado usually at elevations below 6000 feet . rat snakes prefer the grasslands , and lightly wooded forests , sometimes found on ranches and farmland .

pnkb np is located along the eastern slope of the great annamite range which has a wetter climate . the forest habitat of pnkb np is characterized by dense moist evergreen forest with different types such as evergreen forest on limestone above 700 m asl , montane evergreen forest on hills above 700 m asl , evergreen forest on limestone under 700 m asl , evergreen forest on hills under 700 m asl , degraded evergreen forest on hills , tree and scrub savanna on limestone , tree and scrub savanna on hills , agricultural land , and plantations and other land uses ( le et al . 2012 ) . however , the loatian rock rat was found only in evergreen forest on limestone karst under 400 m asl . these data indicate that the laotian rock rat has a very narrow habitat preference which is restricted only to limestone karst covered by evergreen forest , semi - evergreen forest , and mixed deciduous forests .
the reproductive biology of the red - necked wallaby is typical of the patterns found in the brush wallabies . the gestation period is about 30 d and oestrus is post - partum . pouch life is 9 months . breeding is aseasonal on the mainland but seasonal in the tasmanian sub - species .
in an effort to bridge this critical knowledge gap , the scientists have urged others to start conducting robust studies into city rat behavior and movement patterns . to gain access to rat - infested homes and businesses , the scientists recommended “incentivizing” property owners so they’re more willing to open their properties for study . local authorities could , for instance , provide discounts for pest extermination services in return for access , they said .
the captive breeding population will be maintained at the alice springs desert park . asdp staff will negotiate with other institutions interested in breeding central rock - rats , and will liaise with these institutions . data collected from the captive population will add to our knowledge of the biology of the species as well as producing sufficient central rock - rats to allow for a reintroduction if this is deemed necessary . captive animals may go on display at the alice springs desert park as part of the public education programme .
great plains rat snakes are primarily nocturnal , active on the ground but will climb , they like to stay close to permanent water sources . females are thought to lay eggs in july and hatch 2 months later .
despite its name , the black rat exhibits several colour forms . it is usually black to light brown in colour with a lighter underside . in the 1920s in england , several variations were bred and shown alongside domesticated
very secretive snake , hardest snake in colorado to find . rock flipping near drainages , walking around after spring rains may produce . very squirmy , may try to poke you with the tail , doesn ' t hurt adaptation most likely used to confuse predators .
the red - necked wallaby shows pronounced sexual dimorphism with males larger ( ranging from 15 - 27 kg to female ' s 11 - 16 kg ) and move heavily muscled in the fore - arms than females . the back is grey - fawn grading to a bright rufous raiment on the neck and the rump . the undersides are white through to pale grey . light cheek and hip stripes are visible but indistinct . red - necked wallabies are of similar size to swamp wallabies but their rufous raiments are distinctive . eastern grey kangaroos do not have a cheek stripe and are grey through to chocolate with no reddish highlights .
it is a terrestrial snake . the rat snake can grow up to 11 feet in length . colours varied due to different climatic conditions and change in habitats . the rat snake has black tear marks just below the labial . they have numerous cross bars near the tail . it is voracious feeder of rats and mice and frogs . their size and colour are similar to the cobras . rat snakes are found wherever rats and frogs / toads are prevalent . so , of course , they are often found in rice fields and in human habitation . the colour varies from jet black in the hills to yellowish or brown . the female lays about 8 to 16 eggs and the young start their diet on frogs .

and a preference for complex habitats ; this causes strong competition for resources among small animals . this has led to the black rat completely displacing many native species in madagascar , the galapagos , and the florida keys . in a study by stokes
jenkins et al . ( 2005 ) , vongsa ( 2010 ) , and khotpathoom ( 2011 ) reported that in spite of several forest habitat types occurring in phou hin poun nbca ( semi - evergreen forest , vine - bamboo forest , dry deciduous forest , mixed deciduous forest and wetlands ) , the laotian rock rat was found only in limestone holes and in the vicinity of limestone caves at elevations from 263 to 734 m asl . the slopes surrounding karsts formations are covered with both evergreen trees and deciduous trees with little ground vegetation .
prolonged licking of the mouth of one individual by another has so far been reported for two species of rock - wallaby and the red kangaroo . it may occur in other macropodids . it is suggested that the primary function of lip - licking is the transfer of saliva to the fore - stomach of the licker so as to maintain water content of digesta at a sufficient level for efficient digestive fermentation . lip - licking may be a useful behavioural indicator that water intake from milk , vegetation or drinking water is inadequate . the occurrence of the behaviour outside the mother–young relationship is indicative of the high level of cooperation that has evolved in petrogale assimilis .
home range refers to the area in which an animal travels and spends most of its time . it is thought that male and female rats have similar sized home ranges during the winter , but male rats increase the size of their home range during the breeding season . along with differing between rats of different gender , home range also differs depending on the type of forest in which the black rat inhabits . for example , home ranges in the southern beech forests of the south island , new zealand appear to be much larger than the non - beech forests of the north island . due to the limited number of rats that are studied in home range studies , the estimated sizes of rat home ranges in different rat demographic groups are inconclusive .
this is particularly concerning as northern australia has a human population density of one person per ten square kilometres . it also has extensive and largely natural vegetation cover . the red fox , responsible for much of the mammal decline further south , is absent from the area . currently we think the declines are a combination of changing fire frequencies , grazing , and cat predation .
harmless . keeled scales . three yellow body stripes , those on each side of body situated on second and third scale rows ( counting from belly up ) ; pattern of black spots on a red background between the stripes on the back . belly is white , greenish or gray , with a row of small dark spots along edges . young look like miniature adults .
the red - necked wallaby occupies a wide range of habitats but does not travel far from some form of dense cover like tall tussock grasses , shrubs and the shrubby understorey of woodland and forest . however , they range out into clear pasture and grassland from this cover to forage . along the east coast of australia , it is present in a broad gradient of habitat and shares this generalist characteristic with the swamp wallaby . the two species are largely separated by the former ' s preference for the ecotone between dense and open vegetation and the latter ' s preference for dense vegetation . the red - necked wallaby frequently shares habitat with the larger eastern grey kangaroo but a study in victoria showed that the two species rarely associate while foraging .

but as lead author michael parsons warned , city - dwellers can’t afford to indulge their ignorance about their rat neighbors any longer . as city populations continue to balloon worldwide , rodent - related risks and diseases are anticipated to go up and up in the coming decades .
research shows that in new south wales , the black rat prefers to inhabit lower leaf litter of forest habitat . there is also an apparent correlation between the canopy height and logs and the presence of black rats . this correlation may be a result of the distribution of the abundance of prey as well as available refuges for rats to avoid predators . as found in north head , new south wales , there is positive correlation between rat abundance , leaf litter cover , canopy height , and litter depth . all other habitat variables showed little to no correlation .
a typical adult black rat is 12 . 75 to 18 . 25 cm ( 5 . 02–7 . 19 in ) long , including a 6 . 5 to 10 cm ( 2 . 6–3 . 9 in ) tail , and weighs 110 to 340 g ( 4–12 oz ) .
natural history : this species is diurnal , active during the day , and is very alert and fast moving . they seek shelter in rock outcrops , small mammal burrows , as well as in trees and shrubs . they lay 3 - 12 eggs , between the months of june and july , usually in an abandoned rodent burrow incubation is between 44 - 58 days .
ringneck snakes coil their tail and display the red coloration as a defense mechanism to ward off predators , also feigning death . very secretive nocturnal species rarely seen during the day . ringnecks have rear enlarged teeth with mild venom , little threat to humans . breeding occurs in the spring laying eggs under rocks or logs in loose soil early summer , hatching august or september . flipping rocks in spring seems to be a productive method of finding ringnecks .
is a medium sized rat with relatively large ears and a tail that is nearly always longer than the body . individuals weigh between 70 and 300 g , and are between 16 and 22 cm in head and body length and a tail length of 19 cm or longer . males are longer and heavier than are females .

the red - necked wallaby expresses a matrilineal relationship in the females but is not particularly gregarious . thus the female kin may be well spaced out even though they share a home range . even so mothers and their sub - adult sons and daughters and adult female relatives are frequent associates . individuals resting in cover are usually on their own but small groups may form in open foraging habitat . these aggregations are typically much smaller than those of sympatric whiptail wallabies or eastern grey kangaroos .

habitat modification is believed to be one of the most significant threats to this vulnerable marsupial , with habitat clearance , exotic plant invasion , changed fire regimes , exotic herbivore grazing , and residential and tourist developments , all impacting and altering the brush - tailed wallaby’s habitat ( 2 ) . predation by introduced red foxes ( vulpes vulpes ) is also considered to be one of the major reasons behind these declines , as these agile predators can reach the wallaby’s once inaccessible refuges ( 2 ) .
the lesson we can learn from the red - necked wallaby and one which seems to be shared with a number of other macropod species living in the more predictable temperate and tropical climates , is that populations move to an equilibrium with their resources and self - regulate . when these populations are perturbed by lethal control measures the brakes are released from reproduction and recruitment may accelerate . likewise if resources are improved with fertilisers and irrigation / watering , the accelerator may be depressed for a time before a new equilibrium is reached .

species impact : implicated in decline of native fauna in hawaii ( atkinson 1977 ) , though amarasekare ( 1994 ) found no evidence that this species is an important predator on honeycreepers on western mauna kea . rat control reduced predation on dark - rumped petrel on maui ( buxbaum 1973 ) . implicated as a contributor in the decline of the ancient murrelet and other burrow - nesting seabirds ( see bertram and nagorsen 1995 ) .
to secure populations in the wild it is necessary to reduce or eliminate the threatening processes . although fire is implicated in the decline of the species there may be other factors that have also contributed . it has been suggested that horses and cattle may have had a detrimental effect on central rock - rats . predation by cats and foxes may also have had an effect , however , the density of these predators seems to be very low in the ranges . this study will attempt to determine potential threatening processes .
once one of the most widespread of the rock wallabies , this bushy - tailed species has been greatly reduced in both numbers and range ( 3 ) . in the nineteenth and early twentieth centuries , this species was valued for its skin , as well as being thought of as an agricultural pest , and as a result hundreds of thousands were killed ( 3 ) . today , numerous threats continue to impact populations , including predation , competition , exotic plant invasion , habitat modification , fire , drought and disease ( 2 ) .
this species was once widespread throughout britain until the brown rat was introduced ( 4 ) . it originates from asia , and today is widely distributed around the globe ( 4 ) . it has been restricted to largely transient populations in southwark , london and avonmouth since 1884 , and has undergone a drastic decline in range since the 1950s ( 4 ) . it also persists on lundy island in the bristol channel and the shaint islands in the outer hebrides ( 4 ) .
when black rat populations are presented with a wide diversity of foods , they eat only a small sample of each of the available foods . this allows them to monitor the quality of foods that are present year round , such as leaves , as well as seasonal foods , such as herbs and insects . this method of operating on a set of foraging standards ultimately determines the final composition of their meals . also , by sampling the available food in an area , the rats maintain a dynamic food supply , balance their nutrient intake , and avoid intoxication by secondary compounds .

according to mike griffin ( pers . comm . ) , all a . chrysophilus in namibia could be a . ineptus if recent research on karyotypes is confirmed .
justification : listed as least concern in view of its wide distribution , presumed large population , and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category .
this species is found from southern kenya to northern south africa , and eastwards to namibia and southern angola . it is found on plains and high plateau , but it is not found in montane areas .
the population density of this species is variable , it can be locally abundant .
this is typically a savanna species , but it is also found in cropland and secondary forests .
there are no major threats to this species . however , as this species relies on ground cover , overgrazing and imprudent fire management could cause local declines and should be avoided .
they occur in kruger national park ( north of the olifants river ) and kgalagadi transfrontier park .
this errata assessment has been created because the map was accidentally left out of the version published previously .

critically endangered b1ab ( iii ) + 2ab ( iii ) ver 3 . 1
listed as critically endangered because its extent of occurrence is less than 100 km² and its area of occupancy is probably less than 10 km² , all individuals are in a single location , and there is continuing decline in the extent and quality of its habitat . surveys by government agencies have not revealed the presence of this species in other adjacent localities ( molur
. 2005 ) . recent surveys located the species in 2013 to 2014 in the shervaroy hills ( kumar 2015 ) .
there is no population information available for this species , though it is presumed the population size is very small , because in a recent survey only 12 adults were recorded during four months of survey between september and december 2014 ( kumar 2015 ) .
it is a nocturnal and fossorial species , which occurs in tropical dry deciduous scrub forest , where it is seen in rocky areas ( molur et al . 2005 ) . in a recent survey , populations of c . elvira were found in rocky habitat living in rocky clifts and the gaps between rocks , which were surrounded by sparse grass , herbs and tall trees ( kumar 2015 ) .
2005 ) . the mining and dumping of debris in the foothills of small hillocks in the reserve forest boundary might cause severe damage to the habitat , as well as uncontrolled grazing in the rocky areas which might also have a negative impact on the habitat ( brawin kumar pers . comms . ,
monadjem , a . , taylor , p . j . , denys , c . and cotterill , f . p . d . 2015 . rodents of sub - saharan africa - a biogeographic and taxonomic synthesis . de gruyter , berlin / munich / boston .
aethomys , chromosomal , morphological and molecular evidence support the recognition of micaelamys as a distinct genus ( baker et al . 1988 , russo 2003 , chimimba 2005 , lecompte et al . 2008 ) . micaelamys namaquensis can be can be distinguished from m . granti on morphological and chromosomal grounds ( visser and robinson 1986 , 1987 ; chimimba et al . 1999 ) . in m . namaquensis the tail is relatively longer , the ventral pelage is often pure white , and there are only three pairs of nipples ; whereas , in m . granti , the ventral pelage is never pure white ( usually grey or greyish ) , and there are five pairs of nipples ( monadjem et al . 2015 ) .
justification : listed as least concern in view of its wide distribution , tolerance of a broad range of habitats , presumed large population , and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category .
this species is generally found south of the caprivi strip throughout most of the southern cone of africa , excluding southern parts of mozambique .
in northern parts of the range ( namibia ) , it is only found areas of shifting sand , otherwise it is found in most habitat types . this species shelters in rocky crevices , hollow trees or in burrows constructed under logs or dense shrubs . nests of this species have been found in trees up to 2 metres . it is a nocturnal and communal species . it is a human commensal , and is found houses and huts .
there are no conservation measures in place ; it is not known if the species is present in any protected areas .
this amended version of the 2016 assessment reflects the taxonomic change in the species name . the range map was accidentally left out of the previous published version of this assessment and that omission is also corrected in this amended version .
the range of this species covers at least all of northern coastal angola , including the cabinda enclave , and the adjacent escarpment zone , extending southwards to the vicinity of lobito ( hanha estate ) . it is also known to occur east of latitude 17°e , in the cassange lowland . this species is probably distributed throughout northwestern angola as it is largely associated with savannas interspersed with forest .
this species inhabits savannas , and also savanna interspersed with forest . it is not known if the species can persist in disturbed or modified habitats .
the population size and abundance of this species is not well known . the species was thought to be extinct ( no records between 1960 and 1996 ) , and was subsequently rediscovered in fourteen sites in 1996 - 2001 , with subsequent disappearance from most of these sites ( e . g . nano 2008 ; edwards 2013a ; dickman et al . 2014 ) . records since 2001 are restricted to a few sites , and the size of these subpopulations is unknown but probably very small ( mcdonald et al . 2013 , 2015a 2015b ; woinarski et al . 2014 ) . woinarski et al . ( 2014 ) considered that the population size was < 1 , 000 mature individuals , albeit with low reliability .
threats are not well resolved . recent evidence has shown predation by feral cats ( mcdonald et al . 2013 ) . other threats may include predation by dogs or foxes ; inappropriate fire regimes ; and habitat degradation due to weeds ( woinarski et al . 2014 ) .
most or the remaining known occurrences are within conservation reserves . the species is listed as threatened under australian legislation and on appendix i of cites . nonetheless , the species is probably undergoing ongoing decline because threats are not effectively managed . more information is required on distribution , population size and threats . formerly - held captive breeding populations have now been abandoned . intensive threat management and reintroductions will be needed for conservation security .

with brownish upperparts that feature distinct pale mottling , and pale underparts with dark scalloping , the western bristlebird is a distinctive inhabitant of the heathlands of south - western australia .
the western bristlebird lays two dull - white , spotted eggs in a large domed nest of sedges , rushes and sticks .
the frequency of burning these habitats determines the structure of the component vegetation . the western bristlebird has been recorded in areas :

the western bristlebird occurs in six subpopulations . the largest subpopulation occurs between two peoples bay and the waychinicup river , and is estimated to contain 1000 birds ( garnett & crowley 2000 ) . the maximum population of the western bristlebird in the fitzgerald river national park is estimated at 300 birds ( higgins & peter 2002 ) . the subpopulation of the western bristlebird in two peoples bay nature reserve has apparently been increasing . up to 60 pairs were present in 1970 , 86 pairs were recorded there in a partial census in 1976 , the population was estimated at about 100 pairs in 1983 and 245 pairs in 1991 ( cale & burbidge 1993 ; smith 1987 ) .

the diet of the western bristlebird consists of invertebrates and seeds . known food items include the seeds of anarthria scabra , daviesia spp . and acacia spp . , as well as earthworms , snails and insects such as ants and beetles and their larvae ( buller 1945 ; chapman 1999 ; milligan 1902a ; smith 1987 ) . the western bristlebird forages on or close to the ground , probing leaf - litter or pecking the ground , or gleaning items from the foliage of plants ( smith 1987 ) .

though the overall population of the western bristlebird has declined since the late 19th and early 20th centuries ( mcnee 1986 ; smith 1977 , 1987 ) , the population is considered to be stable ( garnett & crowley 2000 ) or increasing ( chapman 1999 ) . the population of the western bristlebird at two peoples bay nature reserve has increased since 1973 , and it is considered that this has been due to the management policy of excluding fire from the area ( orr et al . 1995 ; smith 1985 , 1987 ) .

the western bristlebird is unlikely to be confused with any other species within its range . however , the noisy scrub - bird has generally similar coloration and also skulks , but is readily identifiable by its barred upperparts and lack of scalloping on its underparts , and their calls are very different .

the distribution of the western bristlebird is fragmented , with populations in fitzgerald national park separated from those in the hassell beach / waychinicup national park / two peoples bay nature reserve area ( barrett et al . 2003 ; higgins & peter 2002 ; mcnee 1986 ) . the distance between these areas is about 120 km and , although the intervening area has been extensively surveyed , no western bristlebirds have been recorded , despite the habitat being apparently suitable for the species ( gilfillan et al . 2007 ) .

the former distribution of the western bristlebird is poorly known . the first specimen was collected in 1839 near perth ( mcnee 1986 ; serventy 1948 ; whittell 1941 ) , but has not been seen there since . the species was certainly at king george sound and near wilsons inlet ( mcnee 1986 ) . fossil remains are known from near augusta ( baird 1991 ) .
the western bristlebird has declined in the western part of its original range ( higgins & peter 2002 ; mcnee 1986 ; smith 1987 ) . it previously occurred near albany , at wilson inlet and king george sound between the late 1860s and 1912 ( glauert 1945 ; serventy 1948 ; smith 1987 ; whitley 1971 ; whittell 1936 ) . it was reported at beaufort inlet in april 1976 and october 1977 ( blakers et al . 1984 ; mcnee 1986 ) , but has not been seen there since ( mcnee 1986 ) .

two mitigation approaches have been adopted for the western bristlebird : translocation of bristlebirds ; and fire management strategies in concert with long - term population monitoring ( burbidge 2003 ; danks 2004 ) . however , the translocated population near walpole does not seem to have survived . it is unknown whether this was due to the fires that burnt the area in the autumn of 2001 or other factors .
the western bristlebird can survive ( or escape from ) a fire , provided there is adequate unburnt vegetation nearby ( burbidge 2003 ; garnett & crowley 2000 ; mcnee 1986 ) . after a fire unburnt swampy vegetation dominated by sedges and thickets may be important as a refuge habitat ( smith 1987 ) and western bristlebirds have been recorded setting up new home ranges in the nearest available unburnt habitat ( burbidge 2003 ; gilfillan et al . 2007 ) . in moist areas , vegetation may be colonised as soon as 23 years after burning ( burbidge 2003 ) .

coastal sw western australia between two peoples bay and waychinicup , and in fitzgerald river national park . small translocated population near walpole ( w of albany ) may now be extinct .
the western bristlebird occurs in three distinct locations : fitzgerald river national park , hassell ( cheynes ) beach / waychinicup national park / two peoples nature reserve , and a translocated population near walpole , though this last population may no longer occur there ( barrett et al . 2003 ; gilfillan et al . 2007 ; mcnee 1986 ) . there is also a record of two western bristlebirds at kundip nature reserve from december 2003 ( buchanan 2004 ; napier 2004 ) , but it is unknown whether this record represents a permanent subpopulation or was a record of vagrant or dispersing birds ( gilfillan et al . 2007 ) .

fire the main threat to the western bristlebird is extensive , or frequent , fire . fires at intervals of less than 510 years may lead to its local extinction ( smith 1987 ) . the optimum fire frequency for the species is unknown , however , the maximum fire frequency to maintain viable populations of the western bristlebird is not less than 20 years ( burbidge 2003 ) . severe or large scale fires have the potential to destroy all suitable habitat , including refuges ( gilfillan et al . 2007 ; mcnee 1986 ; smith 1977 , 1987 ) . fire frequency greater than every 510 years will lead to the extinction of a population , but what happens to its heath habitat in the absence of fire for 50 or more years is unknown . some areas of heath around mt . gardner have not been burnt for at least 45 years and the density of birds in these areas is less than in areas burnt 20 years ago ( smith 1987 )

being a ‘skulking’ species , western bristlebirds are seldom seen but often heard , as they are often difficult to see , generally staying concealed among the dense vegetation of coastal heathlands . their song is a distinctive , melodious whistle .
western bristlebirds inhabit inhabit coastal heathlands with a diverse range of dense , low - growing shrubs . they occur in areas that have not been burnt for some years , but the time between burning and reoccupation varies between different sites .
in the absence of fire at two peoples bay , home - ranges have remained stable over the last 30 years ( burbidge 2003 , 2007 , pers . comm . ) . here , the home - range of pairs of western bristlebirds , determined by mapping locations of singing birds , was estimated at 6 . 5 ha ( range 68 ha ) , with pairs spending at least 60 % of their time in a core area of 13 ha ( smith 1987 ) . one radio - tracked western bristlebird , at two peoples bay , had a home - range of 6 ha , and another had a home - range of 21 ha ( murphy 1994 ) . in the fitzgerald river national park , population densities of western bristlebirds have been estimated at 0 . 1 birds / ha ( smith & moore 1977 ) , and 0 . 3 birds / ha at two peoples bay ( higgins & peter 2002 ) . near mt gardner , at two peoples bay , 12 pairs were recorded in an area of about 80 ha ( smith 1987 ) .
western bristlebirds forage on or close to the ground , taking mainly invertebrates , including worms , snails and insect and their larvae , as well as seeds . they constantly peck at the ground , using the bill to probe beneath the leaf litter or sweep fallen leaves aside .

a small population of western bristlebirds was translocated to near walpole , western australia ( burbidge 2003 ; garnett & crowley 2000 ) . eight birds were translocated in 1999 with a further seven being added in 2000 . a number of birds persisted after a fire in 2001 , with at least five heard calling in 2002 , but only one bird was heard calling between 2003 and 2005 , and none has been heard since 2005 ( burbidge 2003 ; gilfillan et al . 2007 ) . further translocations may be considered in the future , but need careful consideration as the success of this first translocation is uncertain ( gilfillan et al . 2007 ) .
eight western bristlebirds were translocated from two peoples bay nature reserve to near walpole , west of albany , in the spring of 1999 , and another seven were translocated in the spring of 2000 . although the area was burnt in a bushfire in the autumn of 2001 , at least seven birds persisted into the winter of 2001 ( burbidge 2003 ) , but there is no evidence of persistence since mid - 2005 ( gilfillan et al . 2007 ) .

2010 ) , estimated to comprise c . 1 , 000 mature individuals ( garnett
2011 ) . the density of birds is greater in the manypeaks - waychinicup areas than in the fitzgerald river national park , but reasons for this are unknown . the albany to mt manypeaks area population declined from c . 500 pairs in 2001 to 200–315 pairs in 2005 and 2006 , largely as a result of wildfires , although the cause for the decline in some areas is unclear . the fitzgerald river national park subpopulation numbered c . 125 pairs in 2005 ( burbidge
in 2005 , the known breeding population was estimated at 300 - 450 pairs , probably equating to a total of 1 , 000 mature individuals ( a . burbidge
at the turn of the century , the species was considered to be stable ; however , a series of fires in the two peoples bay - mt manypeaks area between december 2000 and december 2004 impacted the local population ( a . burbidge in litt . 2007 ) . numbers of calling males were reduced from about 500 in 2001 to 200 in 2005 , with similar numbers recorded in 2006 . thus , overall , the population is estimated to have declined over the last three generations .
it is terrestrial and sedentary with a preference for dense , low heaths . in two peoples bay , it occurs in dense , closed heath 1 - 1 . 5 m high . near waychinicup river and in the fitzgerald river national park , it is found mainly in closed heath 0 . 5 m high , sometimes with scattered patches of mallee eucalypts . unburnt swampy vegetation , predominantly sedges and thickets , may be important refuges after fires . at two peoples bay , it can reoccupy heaths less than 3 years after fire , although breeding may not occur until later . it may not reoccupy heaths in drier areas until 11 - 14 years after fire . it was found in heaths 5 - 12 years after fire from boulder hill to east of waychinicup river , and 14 - 28 years after fire in the northern part of fitzgerald river national park .
it is particularly vulnerable to habitat destruction and alteration . wildfire is the principal threat , particularly large - scale wildfires , the incidence and extent of which have been increasing in recent years , despite increased skills , capacity and effort to stop them . fires at less than 5 - 10 year intervals may lead to local extinctions , and such fires are almost certainly the main cause of its historical range contraction . at the other end of the scale , some coastal heath ( at least at two peoples bay ) remains suitable habitat for at least 50 years after fire , although the carrying capacity may be reduced with time . a series of fires in the two peoples bay - mt manypeaks area between december 2000 and december 2004 impacted the local population of this species ( a . burbidge
. numbers of calling males were reduced from about 500 in 2001 to 200 in 2005 ( a . burbidge
. while most of this decline was clearly attributable to large - scale wildfires , some of the decline was most likely due to other , unknown factors ( a . burbidge
2009 ) . clearance for grazing and agriculture caused historical range contractions , but is no longer considered a threat as almost all bristlebirds now occur in protected areas .
surveys have been completed over the range of the species , and populations are protected from fire as much as possible , particularly in association with the other threatened taxa of the two peoples bay - manypeaks area . in 1999 - 2000 and 2007 , 18 birds were translocated to a site west of albany , but the translocation appears to have been unsuccessful and there was no evidence of breeding ( garnett

a site just north of the fitzgerald river national park ( mcnee 1986 ) .
surveys have revealed their presence at 14 different sites in and near fitzgerald river national park ( gilfillan 2007 ) .
the species was not known from areas east of albany until 1945 , when it was discovered at two peoples bay ( buller 1945 ) ; it was subsequently recorded at waychinicup river ( ford 1963 ) , and in fitzgerald river national park in 1976 ( smith & moore 1977 ) .
the populations identified as being important for the species ' long - term survival are those located in the fitzgerald national park and in the area between hassell beach and two peoples nature reserve , including waychinicup national park ( cale & burbidge 1993 ; chapman & newbey 1990 ; garnett & crowley 2000 ; gilfillan et al . 2007 ; mcnee 1986 ; orr et al . 1995 ) .
it also occurs in areas last burnt at least 50 years previously , but at a lower population density than it does in less mature vegetation ( smith 1987 ) .
recovery of its habitat after fire may take longer in relatively dry areas such as fitzgerald river national park than in moist areas such as two peoples bay ( mcnee 1986 ) .
, all of which are listed as threatened taxa under australian or state government legislation ( garnett & crowley 2000 ; mcnee 1986 ; orr et al . 1995 ) .
nothing is known of the role of each sex in nest building , incubation or feeding the nestlings ( smith 1987 ) .
the species is usually detected only by its vocalisations , usually between may and october . it has distinctive calls , which are most intense at dawn and , to a lesser extent , at dusk ( mcnee 1986 ; smith 1987 ; whittell 1936 ) . the song bouts are short and infrequent and large numbers of observations are needed to build up an adequate picture of the area used by the species . there are two song types and three call notes . the most frequently given song is a highly variable melodious whistle of five to eight notes ( smith 1987 ) .
smith ( 1987 ) provides details of many aspects of the species ' biology .
mcnee ( 1986 ) provides information about a comprehensive survey conducted in 1985 , including the composition and structure of suitable vegetation at various sites .
burbidge ( 2003 ) published the results of a study on the effects of bushfires on the species .

automatic vetting based on the ala & apos ; s & apos ; assertions & apos ; whereby observations were assessed as inappropriate for modelling ( ie . & apos ; zero _ coordinates & apos ; , & apos ; invalid scientific name & apos ; ) ;
determining if the observations fell within expert - derived range polygons . these polygons were supplied by birdlife australia to represent , for each species , its core breeding habitat , non - breeding , historic , irruptive , or invasive ranges . records that fall outside these ranges were marked as inappropriate for modelling ; and
human - derived classification of records after previous two assessments . through the edgar project ( urltoken ) , users were able to map all species observations and comment on the suitability of records for distribution modelling . this included records deemed inappropriate by other means .
every 6 months the occurrence record download file is updated to reflect recent vetting by experts . in the data download , sensitive records have been obfuscated by truncating the lat / long to two decimal places . obfuscated records will be indicated in the data file . access to the accurate data will need to be arranged with the original data owners - contact the ala for more information .
the resulting downloadable file of occurrence records reflects which records are suitable for species distribution modelling .

the advanced search popout allows you to build / refine complex queries all in a single tabbed popout . from within the advanced search you can construct boolean searches and apply one or more filter categories to your search .
note that there is no defined order to the tabs in the advanced search and you can apply the filters in any order you choose . where there are multiple options for a filter category e . g . ( subjects ) the options & record counts displayed are based on your query . each time you switch tabs the available filter options and record counts are updated to reflect any changes on the previous tab .
as you build / refine your search in the advanced search popout , you can review the entire search and the number of results which will be returned by selecting the ‘review’ tab . the tab also allows you to modify your search by removing filters .
the query constructor provides a way of searching for records using multiple search term combinations and boolean operators .
the advanced queries created using the query constructor are comprised of rows . each row consists of a field , condition operator and a value . the value tells the search what to look for , the field tells the search where to look , and the condition operator tells the search whether a record should ‘contain’ or ‘exclude’ the value .
multiple search terms entered into a single condition value are treated by the search as being separated by the boolean operator and .
the search terms are treated as case insensitive e . g . ‘rain’ is the same as ‘rain’ .
exact phrases can also be entered into condition values by using quotes
e . g .
ice sheets
the ? symbol can be used to perform a single character wildcard search . e . g . organi ? ations .
the * symbol can be used to perform multiple character wildcard search . e . g . extend *
note : wildcard characters can be applied to single search terms , but not to search phrases .
the query constructor supports the use of the boolean operators ‘and’ & ‘or’ between query rows . the operators are applied at the search level , meaning all query rows are separated by the same boolean value . changing the boolean value between two query rows will change the value between all query rows .
here we will step through constructing an advanced query where we would like to find all the records which contain ‘rain’ in the title , and ‘flood’ and ‘weather’ in the description .
open the advanced search popout and ensure you are on the ‘search terms’ tab . two query rows should be displayed by default .
in the empty value field in the 1st query row enter the search term ‘rain’ .
in the empty value field in the 2nd query row enter the search term ‘flood’ .
in the empty value field in the 3rd query row enter the search term ‘weather’ .
the subject tab allows you to refine your search by selecting subjects which have been used to describe data records . the default subject vocabulary in research data australia , and the one which is used consistently by data providers , is the anzsrc field of research . other supported subject vocabularies are also available and can be selected by using the drop down displayed at the top of the tab ( note that these can take a little while to load ) .
subject vocabularies are displayed as browsable hierarchical trees . subject literals displayed as green links can be clicked to display or hide child subjects .
subjects can be added or removed from your search by using the checkbox displayed with each subject literal . multiple subjects can be selected within a single subject vocabulary and also across vocabularies .
the number of records with a subject will be displayed at the end of each subject literal e . g ‘economics ( 30 ) ’ . note that because the relationships between records and subjects are many to many , the counts displayed with the subjects will not necessarily match the count of records returned by your search . for example you may see 3 subjects all showing a ( 1 ) beside them . this could resolve to a single record containing all 3 of the subjects . where no records exist with a subject value a ( 0 ) will be displayed with the literal .
the data provider tab allows you to limit your search to records published to research data australia by specific providers . the number of records available from providers will be displayed at the end of each provider literal e . g ‘bond university ( 25 ) ’ .
data providers can be added or removed from your search by using the checkbox displayed with each data provider literal .
the access tab allows you to limit your search to records with specific access types . data records in research data australia fall into one of four access types :
data that is accessible and reusable , providing certain conditions are met ( e . g . free registration is required )
data access is limited in some way ( e . g . only available to a particular group of users or at a specific physical location )
the number of records available in each access type will be displayed at the end of the access literal e . g ‘open ( 23 ) ’ .
access types can be added or removed from your search by using the checkbox displayed with each access literal .
