Distribution. Europe to Western Siberia, Asia Minor and Palestine. In Winter South to Northern Africa and into the North-Western Himalayas.

Nidification. In Europe the Goshawk builds its own nest high up on trees, adding to it every year so that it eventually becomes an immense affair. It is built entirely of sticks, some small and some very large and is lined and edged with smaller twigs. The eggs, two to four in number, rarely five, are white or bluish-white, very rarely faintly marked with blotches of pale reddish. One hundred eggs average 58.0 x 45.2 mm. (Witherby). The breeding-season is April and May but D. Meinertzhagen took fresh eggs as late as the middle of June in Finland.

Habits. The Goshawk is a bird of forests and well-wooded districts, of powerful flight and great courage. It feeds on hares, rabbits, squirrels, game-birds of all kinds, as well as on rats, mice and small birds. It watches for its game from a fixed perch, whence it launches forth on its prey. Its call is a loud squeal or scream and it also has a short quick note which Hartert syllabifies as " gyak, gyak, gyak."
