The steppe eagle is a large bird of prey, 60 to 89cm long, a booted eagle with well-feathered, almost dishevelled-looking legs. It is mainly dark brown, with a longish, very thick neck and a relatively small head with a strong bill and long gape line, and it looks long-winged with a longish, rather rounded tail (Wikipedia, general species account).
It makes a massive migration from essentially its whole breeding range, moving in large numbers past major flyways, among them those of the Himalayas. On the breeding grounds it is a specialised predator of ground squirrels, and it is the only eagle to nest mainly on the ground. One to three eggs are laid, and maturity comes between the fourth and fifth years. Declines are worsened by disturbance, persecution and nest trampling by livestock.
