All aspects of the natural history of Caspian Terns are of interest to me but I am particularly concerned with questions related to movement, diet, and distribution of this cosmopolitan species. My primary field work has been focused in western North America especially in the Columbia River Estuary at what is currently the world's largest colony of this species. I have done small amounts of Caspian Tern field work in Mexico, Australia, New Zealand, and South Africa and hope to continue collecting observations throughout the geographic range and for the entire life cycle. In developing techniques to identify Caspian Tern bill loads I have become more generally interested in species that carry prey in their bill and the utility of the technique for both applied and theoretical work.
