Well known for their V-shaped migrating flocks and rich, sonorous honking, Canada Geese are among the most familiar of North America's waterfowl. There were formely 11 geographical races recognized, but the smaller races have recently been established as a separate species, called the Cackling Goose (B. hutchinsonii). The larger races, ranging in size from the "Giant Canada Goose" of the northern prairies to the much smaller "Lesser," remain part of the Canada Goose complex. The most abundant race is the one that nests south of Hudson Bay, which numbers well over a million. Like other geese, these birds are chiefly grazers, feeding on stubble fields and eating marsh vegetation. Increasingly tolerant of humans, some Canadas even nest in city parks and suburbs. They are especially noticeable in late summer and early fall, when they form molting flocks on golf courses and large lawns; at such times, they have come to be regarded as pests.
