Home range and foraging habitat of American Crows, Corvus brachyrhynchos, in a waterfowl breeding area in Manitoba

Abstract

American Crows were studied from April to July in 1986 and 1987 in southwestern Manitoba. Home ranges averaged 2.6 km. Foraging flights from the nest averaged 382 m; flights longer than 700 m were infrequent. American Crows used habitats for foraging in proportion to their occurrence within home ranges, but large individual variation existed. American Crows avoided tall vegetation while foraging, and seldom encountered duck nests.
