Bioacoustic analyses of the chick-a-dee call of the Mexican chickadee (Poecile sclateri) and the boreal chickadee (Poecile hudsonica)Download
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...
A re-examination of ZENK expression following hetero- and conspecific playback in the zebra finch auditory forebrainDownload
Zebra finches (Taeniopygia guttata) are one of the most sexually dimorphic songbirds used as model species, not only in appearance but also in vocal production; while males produce both calls and songs, the females only produce calls. This dimorphism in the zebra finch provides a means to...
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...
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...
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...
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...
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...
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...
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...
