View article: Insights into detection probability of forest bird surveys from comparison of in-person and passive acoustic monitoring point counts
Insights into detection probability of forest bird surveys from comparison of in-person and passive acoustic monitoring point counts Open
Historically, research and monitoring of bird populations has been conducted with in-person point counts; however, passive acoustic monitoring (PAM) recordings transcribed by experts (“PAM point counts”) are rapidly replacing in-person sur…

Contributions of environmental conditions and sound characteristics to differences in perceptibility: Recommendations for passive acoustic monitoring Open
Passive acoustic monitoring is increasingly used in ecological research to study a wide variety of taxa; however, properly accounting for perceptibility, a component of detection probability, has been challenging because sound attenuation …

Pacific Northwest birds have shifted their abundances upslope in response to 30 years of warming temperatures Open
Mountain species are predicted to respond to warming temperatures by moving to higher elevations that remain relatively cool. Species can track warming by shifting their entire distributions upwards (the “escalator to extinction” hypothesi…

Audio data compression affects acoustic indices and reduces detections of birds by human listening and automated recognisers Open
Increasing popularity in passive acoustic monitoring and the ease with which researchers can accumulate large quantities of acoustic data has resulted in challenges for audio recording storage, archiving, and management. Reductions in file…

Quantifying Firebrand Production and Transport Using the Acoustic Analysis of In-Fire Cameras Open
Firebrand travel and ignition of spot fires is a major concern in the Wildland-Urban Interface and in wildfire operations overall. Firebrands allow for the efficient breaching across fuel-free barriers such as roads, rivers and constructed…

Automated classification of avian vocal activity using acoustic indices in regional and heterogeneous datasets Open
Acoustic indices combined with clustering and classification approaches have been increasingly used to automate identification of the presence of vocalizing taxa or acoustic events of interest. While most studies using this approach standa…

Modeling the occurrence of the Yellow Rail (Coturnicops noveboracensis) in the context of ongoing resource development in the oil sands region of Alberta Open
Hedley, R. W., L. J. T. McLeod, D. A. Yip, D. Farr, P. Knaga, K. Drake, and E. Bayne. 2020. Modeling the occurrence of the Yellow Rail (Coturnicops noveboracensis) in the context of ongoing resource development in the oil sands region of A…
View article: Sound level measurements from audio recordings provide objective distance estimates for distance sampling wildlife populations
Sound level measurements from audio recordings provide objective distance estimates for distance sampling wildlife populations Open
Distance sampling is widely used to estimate animal population densities by accounting for imperfect detection of individuals with increasing distance from an observer. Distance sampling assumes that distances are measured without error; h…

Sound attenuation in forest and roadside environments: Implications for avian point-count surveys Open
Point counts are one of the most common ways of collecting data to determine the relative abundance of birds. Many studies and monitoring programs, including the North American Breeding Bird Survey, use relative differences in counts of bi…

Experimentally derived detection distances from audio recordings and human observers enable integrated analysis of point count data Open
Point counts are one of the most commonly used methods for assessing bird abundance. Autonomous recording units (ARUs) are increasingly being used as a replacement for human-based point counts. Previous studies have compared the relative b…
