Social behavior, boldness, and learning in jays

For my PhD dissertation I color-banded populations of wild Mexican jays (Aphelocoma wollweberi), a communal cooperative species, and the relatively asocial California scrub-jay (A. californica) to study the relationship between social behavior, boldness and learning.  I used a puzzle box task to compare species ability to individually and socially learn. I also used two different assays to measure boldness, and I conducted focal follows to quantify social network structure of each species.

The distinct social environment of the two species was related to interesting differences in learning and boldness.  See the published results here. See videos of this work here.

Behavioral ecology of a species with a rapidly expanding range

As a postdoctoral researcher, I currently study great-tailed grackles (Quiscalus mexicanus) in Tempe, AZ.  Endemic to Central America, grackles expanded their range into AZ ~85 years ago.  As part of The Grackle Project, led by Corina Logan, I've created experiments to measure individual variation in boldness and exploration, space use behavior, and learning. Ultimately, we will compare these behaviors in grackles from populations across the current range to determine which characteristics enable species to invade new areas.
