The perception, structure, and function of female song in the black-capped chickadee (Poecile atricapillus)
DownloadFall 2021
The black-capped chickadee (Poecile atricapillus) is a non-migratory songbird found throughout North America who communicates primarily through its numerous vocalizations, each with various functions. The vocalizations of the black-capped chickadee can be divided into calls and songs. Calls serve...

The Neural Encoding of Heterospecific Vocalizations in the Avian Pallium: An Ethological Approach
DownloadFall 2011
Songbirds (order Passeriformes, suborder Oscines) have captured the attention of scientists and non-scientists alike with their vocal signals. The black-capped chickadee (genus Poecile) uses its namesake call, chick-a-dee, to convey a variety of information. In Chapter 2 and 3, I examine the...

Anthropogenic noise is increasingly widespread as human development continues. Noise can negatively affect humans and wildlife, but the most deleterious effects are incurred by species that rely on vocal communication for mating, territory defence, and other vital functions. Songbirds are...

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...

Perception and communication of predator threat in the black-capped chickadee (Poecile atricapillus)
DownloadFall 2019
The black-capped chickadee (Poecile atricapillus) is a type of North American songbird that produces multiple vocalizations, including their namesake chick-a-dee call. This call is used as a mobbing call to recruit and coordinate conspecifics in the presence of a predator. These parids perceive...

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...

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...

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...

Bioacoustic analyses of the chick-a-dee call of the Mexican chickadee (Poecile sclateri) and the boreal chickadee (Poecile hudsonica)
DownloadFall 2009
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...

Spring 2020
Black-capped chickadees (Poecile atricapillus) are a species of North American songbirds commonly studied for their unique vocalizations. The two most studied vocalizations are their fee-bee song, used for mating and territory defense, and their name-sake chick-a-dee call, which has multiple...
