Golden eagle

The golden eagle (Aquila chrysaetos) is a large accipitrid raptor, 66–102 cm in body length with a 180–234 cm wingspan; females average about 5.1 kg against roughly 3.6 kg in males, and the hind claw reaches 4.5–6.3 cm. Dark brown plumage bears golden lanceolate nape and crown feathers. It breeds across temperate and boreal Eurasia, North America and parts of North Africa, some 140 million square kilometres, nesting on cliffs and tall trees to 4,000 m. Hares, marmots, squirrels and birds are taken, as is carrion. The IUCN lists it Least Concern.
