title: ARU audio recordings with ruffed grouse annotations (Pennsylvania, 2020)

description: This dataset contains audio and annotations for ruffed grouse (Bonasa
 umbellus) drumming events. Audio is organized into subfolders by date (4
 dates) and by SD card (each of the 56 SD cards was used to record data
 from an AudioMoth acoustic recorder in Pennsylvania in 2020). For each day
 and SD card there is one 5-minute audio file. The table in the annotations
 folder contains presence/absence (ie 1 or 0) labels for each minute (eg
 0-60 seconds, 60-120, ...) of each audio file. Additionally, the
 annotations folder contains subfolders with annotation text files created
 in raven specifying the time and frequency bounds of each annotated ruffed
 grouse drumming event. Audio files with zero annotations do not have an
 annotation .txt file, except one. The file names and directory structure
 of Raven annotation files and audio files are an exact match, except for
 the file extensions (.wav vs .Table.1.selections.txt). This data was used
 to evaluate an automated recognition method designed to detect ruffed
 grouse drumming (Lapp et al 2022) Lapp, S., Larkin, J., Parker, H.,

 Wildlife Society Bulletin (Lapp et al. 2022) Our study
 area consisted of three State Game Lands managed by the Pennsylvania Game
 Commission (PGC) in north central Pennsylvania (see Parker et al. 2020 for
 a detailed description of study area). Each State Game Land (State Game
 Lands 033, 060, and 100) was dominated by forest (88-94%), comprised of
 mostly dry-oak (<em>Quercus</em> spp.) heath, dry-oak
 mixed-hardwood, and red maple (<em>Acer rubrum</em>) cover
 types. Elevations for the study sites ranged from 530 to 762 meters. We
 assessed ruffed grouse drumming in ten regenerating stands where overstory
 removal timber harvests occurred between 2009 and 2012 (meaning that 8 to
 11 years had elapsed since harvest at the time of our pilot
 study). We deployed 60 AudioMoth acoustic recorders
 within the ten regenerating timber harvests selected for our case study.
 Survey locations were spaced at least 200 meters apart. AudioMoths were
 programmed to record audio at a 32 kHz sampling rate for three 30-minute
 periods each morning and recorded for four weeks during peak ruffed grouse
 courtship, from 19 April to 16 May 2020. Four devices malfunctioned or
 were lost during the deployment (e.g., water or black bear
 [<em>Ursus americanus</em>] damage), resulting in 56 locations
 with audio recordings distributed across the three State Game
 Lands.  We performed 5-minute acoustic drumming surveys
 on four dates at each location by listening to the audio recorded by ARUs
 at each location and annotating all drumming events using Raven Pro
 software. The four ARU-based human point count dates were spaced across
 the ruffed grouse monitoring season (25 April, 1 May, 7 May, and 16 May)
 and contained audio from 07:40-07:45 Eastern Daylight Time. All
 annotations of ruffed grouse drumming were cross-evaluated by a second
 reviewer for accuracy. This effort resulted in a total of 224 annotated
 5-minute audio clips. Lapp, S., Larkin, J., Parker, H.,
