Great Grey Owl

Strix nebulosa

The Great Grey Owl is the tallest owl in North America, with a massive rounded head, piercing yellow eyes, and concentric grey facial discs. Despite its imposing size, much of its bulk is fluffy feathers — it weighs less than a Great Horned Owl. It hunts rodents by sound alone, plunging through deep snow in boreal forests across the Northern Hemisphere.
