The Cackling Goose looks like a miniature version of the widespread Canada Goose, with which it was once combined as a single species. The two are almost identical in plumage, but Cackling Geese are more delicate, with stubbier bills, steeper foreheads, shorter necks (strikingly apparent in flying birds), and usually more rounded heads. Their calls are higher in pitch than those of Canada Geese. Like their larger relatives, Cackling Geese forage in marshes and fields in large flocks, often mixed with other goose species.
