Long-eared Owl

Open encyclopedia reference

The long-eared owl (Asio otus), also known as the northern long-eared owl or informally as the lesser horned owl or cat owl, is a medium-sized typical owl with an extensive range. The genus name, Asio, is Latin for "horned owl", and the specific epithet, otus, is derived from Greek and refers to a small eared owl. It breeds in Europe and the Palearctic, as well as in North America. This owl prefers semi-open habitats, particularly woodland edge, as they to roost and nest within dense stands of wood but prefer to hunt over open ground. The long-eared owl primarily hunts small rodents, especially voles, but during population cycles of their regular prey, or in arid, insular, or urbanized habitats, it takes diverse prey including birds and insects. The long-eared owl utilizes nests built by other animals, in particular by corvids. Breeding success in this species is correlated with prey populations and predation risks. Unlike many owls, long-eared owls are not strongly territorial or sedentary. They are partially migratory or nomadic.
