Chickadees produce many vocalizations, including chick-a-dee calls which they use as a mobbing call in the presence of predators. Previous research has shown that chickadees produce more D notes in their mobbing calls in response to high-threat predators compared to low-threat predators, and may...

Canada’s boreal forest is the breeding ground for some 288 species of resident and migratory birds. Approximately 65% of the species that are currently of highest conservation priority in the boreal region are associated with wetlands and riparian areas. Although estimates vary with scale and...

The Canadian boreal forest is vital breeding habitat for North American songbirds. Extensive anthropogenic disturbances within this biome are therefore of conservation concern. Using unharvested stands as controls, I examined the effects of variable retention management (VRM) relative to...

Discrimination of musical intervals by humans and chickadees: Cue salience modulated by timbre
DownloadFall 2013
Musical consonance/dissonance, roughly defined by its characteristic stability/instability, has been shown to be a relatively salient feature of sound. The extent to which the salience of this property varies as a function of timbre, a property that distinguishes two sounds of the same pitch and...

Animals must assess the risk of mortality due to starvation or predation when making foraging decisions. This decision-making can be guided by cues from the environment, conspecifics, heterospecifics, or by predators themselves. Information theory predicts that high certainty cues should be...

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...
