Differs in habits from B. vulgaris, in that t is more a bird of the open, rocky country, and does not frequent woodlands. Its cry is the same but deeper and more melancholy in tone. It feeds on lemmings, and other small mammals, frogs, lizards, even insects, and also on young birds. Its nest is either in a tree standing in the open, placed on the ground, or on a cliff or rock, and is constructed of sticks lined with grass, and 3 to 4, sometimes 5 eggs are deposited, usually in May or June, but in a year when lemming were very numerous, fresh eggs were taken in Norway as late as the 9th September. These re¬semble the eggs of B. vulgaris, but are often more richly coloured, and measure about 2.25 by 1.75.
