ABSTRACT
The lesser snow goose (Anser caerulescens caerulescens) is a sexually monomorphic species. Two color phases, blue and white, occur and interbreed freely. Nesting takes place during summer (May to August) in discrete colonies of variable size throughout the North American and eastern Siberian high arctic and along the Hudson Bay coast. Because pair bonds last through the breeding season, captures of mated birds on the nesting grounds are interdependent events. Flocks from different colonies intermix during migration and overwintering (October to April). Geese from colonies of the Hudson Bay drainage area migrate along the Mississippi and central flyways and winter along the Gulf Coast of Texas and Louisiana.
