Resident Canada goose (Branta canadensis) and human populations in North America are increasing rapidly. Consequently, human-goose conflicts also are increasing. A potential approach to manage Canada goose populations is the use of orally delivered reproductive inhibitors. Nicarbazin, when ingested daily, is a reproductive inhibitor that has the potential to reduce the hatchability of Canada goose eggs. To successfully employ reproductive inhibition, managers must understand the behavior of local Canada goose populations, primarily springtime movements, nesting, and habitat use to develop effective methods for delivering necessary doses. We monitored movement, habitat use, and nesting of 51 resident Canada geese, all adult females, at Bay Beach Wildlife Sanctuary (BBWS), Green Bay, Wisconsin, during 2001 and 2002.
