Until 2004 the Cackling Goose was considered a small race of the Canada Goose. Based on differences in size, voice, habitat, timing of migration, and genetics, the American Ornithologist Union Committee on Classification and Nomenclature designated the Cackling Goose as a separate species. The breeding range is restricted to northwestern Alaska and northern Canada, and it typically migrates to California and the Midwest for the winter. There have been an increasing number of non-breeding season records for the Cackling Goose east of the Mississippi, including in Tennessee.
Description: Cackling Geese look identical to Canada Geese except that they are smaller, nearly the size of a Mallard, and have a proportionately smaller bill. Both species have a black head and neck marked with a contrasting white "chinstrap." The back is brown, the chest and belly are pale, and the tail is black with a white rump band. Males and females are similar in size and appearance.
Weight: 3.5 lbs
