Understory protection is a harvesting approach that seeks to protect understory conifers during hardwood harvesting in mixedwood forests. While understory protection harvesting has been implemented for over a decade in Alberta, there has been no study of its ecological value to birds. We surveyed...

Chickadee behavioural response to varying threat levels of heterospecific and conspecific calls
DownloadFall 2015
Chickadees produce many vocalizations, including the chick-a-dee call that 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...

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...
