Remote camera traps are often applied to large mammal conservation and management programs because they are cost-effective, allow for repeat surveys, and can be deployed for long time periods. Additionally, statistical advancements in calculating population metrics, such as density, from camera...
An investigation of sex differences in acoustic features of the chick-a-dee call of black-capped chickadees (Poecile atricapillus)Download
The chick-a-dee call of the black-capped chickadee (Poecile atricapillus) is composed of four main note types (A, B, C, and D) that occur in a fixed order. Sex differences have been identified in a number of black-capped chickadee vocalizations (including tseet calls and fee-bee songs) and in the...
Bioacoustic analyses of the chick-a-dee call of the Mexican chickadee (Poecile sclateri) and the boreal chickadee (Poecile hudsonica)Download
To understand the communicative functions of any vocalization it is important to first classify, describe, and measure the elements of that vocalization. Mexican (Poecile sclateri) and boreal (P. hudsonica) chickadees both produce a name-sake chick-a-dee call. Here, the note types present in...
Information contained within a simple acoustic signal: The fee-bee song of the black-capped chickadee (Poecile atricapillus)Download
Black-capped chickadees (Poecile atricapillus) are a common North American songbird that produce numerous types of vocalizations with various functions. The vocal repertoire of black-capped chickadees have been the focus of numerous vocal production and perception studies. Black-capped chickadees...
Pre-processing spectrogram parameters improve the accuracy of bioacoustic classification using convolutional neural networksDownload
A variety of automated classification approaches have been developed to extract species detection information from large bioacoustic datasets. Convolutional neural networks (CNNs) are an image classification technique that can be operated on the spectrogram of an audio recording. Using CNNs for...
For male breeding songbirds, song rate varies throughout the breeding season and tends to be correlated with breeding-cycle stages. Although these patterns have been well documented, to our knowledge, this relationship has not been used to predict a bird’s breeding status through acoustic...
Predictive Mapping of Yellow Rail (Coturnicops noveboracensis) Density and Abundance in the Western Boreal Forest via Ground and Satellite Remote SensorsDownload
The Yellow Rail (Coturnicops noveboracensis) is a small, secretive, wetland bird, which is apparently rare throughout most of its range. Almost nothing is known about its abundance and density in the wetlands of the western boreal forest. Emerging technologies have enabled us to effectively...
