Habitat
Forests with openings, ranging from mostly coniferous in the north to beach in south. Quite often in areas near birch or alder swamps. In central Europe only in mountains .
Behaviour
Breeding
They nest in hollow tree trunks. The 2-4 eggs are incubated for 27-34 days. The young leave the nest after about four weeks, but will not fly until about six weeks old. The attending parent has been known to attack humans approaching too closely.
Diet
Mostly active at dawn and dusk with some activity at night; in northern areas also active at day during time of feeding of young. The diet constitutes mainly rodents, supplemented with medium-sized birds such as Jays, Hazel Grouse, and Woodpigeon as needed.
