The great gray owl

The Great Grey Owl is large grey owl with dense, fluffy plumage, long wings and tail, and a large head with no ear-tufts. The species name nebulosa is derived from the Latin Nebulosus, meaning misty or foggy. This Owl is the provincial bird emblem of Manitoba, Canada.

Size: Length 61-84cm. Wing length 387-483mm. Wingspan up to 152cm. Tail length 285-347mm. Weight 790-1454g. Females are larger and heavier than males.

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.
