Snowy owls originating from the Arctic tundra are migrating south to winter in regions of the Great Lakes and Midwest plains, according to migratory bird biologists with the U.S. Fish and Wildlife Service.
The species' rare southerly migration may be the result of a decline in its forage base and a productive breeding season. The snowy owl migration began in October and birds are expected to remain in portions of the United States until late winter/early spring.
Unlike many owls, snowy owls thrive in open grasslands, nest on the ground and hunt mainly during the day. They feed on small mammals, waterfowl, birds and fish. Their coloring, large size, unique hunting behavior and remote habitat distinguish them from other owl species.
