ニシオオノスリ Buteo rufinus

A large, long-winged buzzard which may recall a small eagle in size. Variable plumage with three color morphs. All have obvious dark carpal patches at the wrist of the wing. Juveniles lack the adult’s prominent black trailing edge to the wings. Often hunts from a prominent perch, or sits on the ground and scans for prey. A species of open steppe and desert country, sometimes in more wooded areas but always near big open spaces. Compare with similar Common and Upland Buzzards, as well as Rough-legged Hawk; note long-winged structure, size, and wings held in “V” in soaring flight.
