Influence of forestry and conspecific attraction on habitat use and reproductive activity of the Canada warbler (Cardellina canadensis) in the western boreal forest: Implications for critical habitat identification
DownloadSpring 2017
Recovery strategies for species at risk are legally mandated in Canada and the Government of Canada must identify which habitat is important for a species and which activities result in its destruction. The Canada Warbler (Cardellina canadensis) has been designated as a threatened species in...

Information contained within a simple acoustic signal: The fee-bee song of the black-capped chickadee (Poecile atricapillus)
DownloadFall 2015
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...

Investigating the value of incorporating behavioural measures in a discriminant function developed for sex assignment in black-capped chickadees (Poecile atricapillus)
DownloadFall 2021
Black-capped chickadees (Poecile atricapillus) are a sexually monomorphic species that typically require molecular assays or observation of sex-specific behaviours in the breeding season for accurate sex assignment. We developed a discriminant function in a central Albertan chickadee population...

Urbanization is viewed as a major threat to global biodiversity because of its role in the loss and fragmentation of low-lying, productive habitats associated with coastal plains and river valleys. My study examines the effects of urbanization on the movements and distribution of songbirds in...

Category perception, as Herrnstein (1990) defined it, is a powerful and pervasive cognitive ability possessed by every species in which it has been adequately tested. We have studied category perception of vocal communication signals in songbirds for over 20 years. Our first studies provided us...

We report myiasis by Lucilia silvarum with an overall prevalence of 0.9% in amphibian populations in boreal Alberta. In the period 1998–1999, we documented L. silvarum infestations in wild populations of wood frog (Rana sylvatica), boreal chorus frog (Pseudacris maculata), boreal toad (Bufo...

Pitch perception in vocal learners: Fundamental shared components of pitch processing and biological relevance
DownloadSpring 2013
Pitch perception is important in both music and language perception in humans. Vocal learners, including humans, share the property of learning their vocalizations from a tutor when young. Similar behavioural and neural mechanisms underlying vocal production among different species of vocal...

Pitch perception is not unitary: Evidence for the perception of pitch chroma in black-capped chickadees.
DownloadFall 2015
Pitch perception is mediated by two attributes: pitch height and pitch chroma. These two attributes can be pitted against one another during an octave equivalence task in order to clarify the dominant perceptual mechanism. Pitch chroma mediates the perceptual phenomenon of octave equivalence,...

Pre-processing spectrogram parameters improve the accuracy of bioacoustic classification using convolutional neural networks
Download2021-06-01
Knight, Elly C., Hernandez, Sergio Poo, Bayne, Erin, Bulitko, Vadim, Tucker, Benjamin V.
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...
