Fieldwork

Most of my field work is concentrated in the western United States, including Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming. I also have done field work in Canada (British Columbia, Newfoundland, Ontario, Quebec), Guatemala, Paraguay, and the Dominican Republic.

Recent field work has focused on collecting samples of Steller's Jays and Gray Jays for phylogeographic studies, recording and collecting Spotted Towhees and Sagebrush/Bell's Sparrows for comparison of song and genetic variation, and resurveying historical sites in California for the Grinnell Resurvey Project (view map of project survey areas). This project celebrates the centennial anniversary (1908-2008) of the Museum of Vertebrate Zoology. Specimen-based resurveys are focused on transects in the Lassen region, southern Sierra Nevada region, and western deserts
