This study is designed to evaluate the foraging behavior and colony connectivity of Caspian terns (Hydroprogne caspia) nesting on Goose Island in Potholes Reservoir, with particular emphasis on predation by terns from this colony on ESA-listed juvenile salmonids (Oncorhynchus spp.) from the upper Columbia River.
