The Great grey owl (Strix nebulosa) is is one of the largest owls in the world, and the largest to live in the northern hemisphere. The name "nebulosa" is derived from the Latin "Nebulosus", meaning misty or foggy. It has fluffy plumage, long wings and tail, and a large head. It flies close to the ground, usually less than 6 metres up, except when flying to a nest. The Great Grey Owl is most active at nights, but also at dusk and just before dawn. Great Grey Owls inhabit a range of forested habitats in northern Europe, Asia, and North America.
