The Cackling Goose (Branta hutchinsii) is a species of goose that looks very similar to the Canada Goose (Branta canadensis). Both species share the characteristic black head and neck with a white cheek patch, but Cackling Geese nest in the arctic and tend to be much smaller in size than are Canada Geese. Recent studies have shown that Cackling Geese overlap little with Canada Geese in size and distribution, and are genetically quite distinct, and therefore constitute a separate species..
