Migration
Migratory in northern latitudes, although some owls may stay throughout the winter.
Habitat
Long-eared owls are most often observed in hedgerows, woody draws, and juniper thickets, although they do occur within the forest edge. They are predominantly open-country hunters; however, they are seldom seen because of their nocturnal habits.
Food Habits
Depends heavily on small rodents.
Reproductive Characteristics
Begins nesting in March or April; nests in a stick nest built by other raptors, magpies, crows, or ravens. Clutch size three to six. Incubation about 26 days. Young fledge at 30 to 40 days (FWP). Nests from late April into June. Young just out of nest as late as July.
