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...
Animal cognition and animal personality: Individual differences in exploratory behaviour, learning, vocal output, and hormonal response in an avian modelDownload
The foremost goal of this thesis is to integrate the study of animal cognition with the field of animal personality. In the early 20th century, Pavlov integrated these fields by describing an interaction between associative learning and dogs that exhibited different behavioural types. Since...
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...
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...
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...
Pitch perception in vocal learners: Fundamental shared components of pitch processing and biological relevanceDownload
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.Download
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,...
