Hab. Northern Europe and Asia, as far north as Northern Lapland and Kamchatka ; wandering south in winter to North Germany ; of very rare occurrence in Great Britain ; of accidental occurrence in Western Alaska.
Frequents open places in the woods and plains where trees are scattered about, and in the mountains it is found up to the birch region. It hunts by daylight as well as in the evening, and bright sunshine does not appear to incommode it. Its flight is very Hawk-like and swift, and the bird is by no means shy or even wary. Its food consists of lemmings, mice, &c., and birds even as large as a Willow Grouse, It nests in a hollow tree or in the boxes placed by the natives for the Ducks to lay in, and in May deposits on the bare wood 6 to 8 or even 10 pure white roundish eggs closely resembling those of the Short┬Čeared Owl, but usually smaller, which measure about 1.52 by 1.13. At its nesting-place this owl is very bold and daring and will often swoop down on and strike any one who attempts to rob its nest. Its cry much resembles that of the Kestrel.
