Northern Goshawk

The Eurasian goshawk, the form listed as northern goshawk, is a medium-large raptor with short broad wings and a long tail. Adults are blue-grey or brownish-grey above with a white eyebrow stripe and a barred underside. Females are much larger than males, 58 to 69cm against 46 to 63cm. It is now treated as separate from the American goshawk (Wikipedia, general species account).

It is widespread across temperate Eurasia from Europe to Japan, including the Himalaya in India and Nepal, in deciduous and coniferous forest and sometimes urban parks. It is an opportunistic predator, taking pigeons, crows, grouse and squirrels, and is highly territorial, with nesting pairs defending home ranges of 600 to 4,000 hectares. Most birds are residents, though northern birds move south in winter (Wikipedia, general species account).
