Pacific Black Brant geese are a species of international attention because of their importance to subsistence and sport hunters throughout North America. They are recognized by the U.S. Fish and Wildlife Service as a focal species because of their wide geographic range of breeding and wintering. Research on Black Brant has focused on studies of movement, site fidelity, behavior, and habitat assessment during breeding and non-breeding (winter and migration) periods in California and Alaska to inform population trends and management actions. This project has amassed a large, multi-year data base of individual observations by season that is being used to show how survival probability varies with individual state and how climate may influence breeding and wintering in high latitude areas.
