Habits: The Great Grey Owl is most active at nights, but also at dusk and just before dawn; sometimes active during the day in breeding season.
Hunting & Food: The Great Grey Owl hunts mainly during early morning and late afternoon, especially during winter, but will also hunt during other daylight hours and at night. Although a very large Owl, small rodents are their primary prey (80 to 90% of diet) with voles being the most important food in Alaska, Canada, and Oregon. Pocket gophers are the most important food in California. Other mammals taken include rats, mice, shrews, squirrels, rabbits, chipmunks, moles, and weasels. Birds are rarely captured.
