An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi
An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi
Theses and Dissertations
The investigator attempted to predict the vocal learning propensity from either family pedigree or early vocal babbling (subsong). Pedigree trees suggest the possibility that vocal learning ability may depend on family. We failed to predict vocal learning propensity from subsong, but suggested that subsong may influence vocal learning outcome.

How The Egg Rolls: A Morphological Analysis Of Egg Shape In The Context Of Displacement Dynamics, Ian R. Hays
Theses and Dissertations
Very little is known about how morphology effects the motion, stability and the resulting viability of avian eggs. The limited research that exists focuses on the pyriform or ‘pointed’ egg shapes found in the Alcidea family. This unusual shell form is thought to suppress displacement and prevents egg loss on the cliffside nesting habitat of the Uria genera. Unfortunately, these studies never isolated or quantify the specific morphological features (elongation, asymmetry and conicality) of these pyriform eggs, which limits their applicability to other taxa and hampers a robust proof of concept. We isolated each feature as a variable, produced models …
Slave To The Rhythm: Variation In The Acoustic Signaling Of Picoides Woodpeckers, Alex Baer
Slave To The Rhythm: Variation In The Acoustic Signaling Of Picoides Woodpeckers, Alex Baer
Theses and Dissertations
We explored rhythmic variation in acoustic signals by geography across four species of Picoides woodpeckers. We hypothesized that there would be an effect of geographic location on the cadence of drums and rattle-type calls. No significant effect was observed. However, drum cadence was observed to significantly impact conspecific recognition in playbacks.
