The steppe eagle is a large bird of prey, 60–89cm long and mainly dark brown, with a longish but very thick neck, a relatively small head with a strong bill and long gape-line, long wings, a longish rounded tail and markedly well-feathered legs. It is a specialised predator of ground squirrels on the breeding ground, also taking other small mammals and prey when squirrels are scarce (Wikipedia, general species account).
It is the only eagle to nest primarily on the ground, usually laying one to three eggs, with one or two young fledging in successful nests. It undertakes a massive migration from essentially its entire breeding range, moving en masse past major flyways such as those of the Middle East, the Red Sea and the Himalayas (Wikipedia, general species account).
