Steppe Eagle (Aquila nipalensis)

[order] Falconiformes | [family] Accipitridae | [latin] Aquila nipalensis | [UK] Steppe Eagle | [FR] Aigle des steppes | [DE] Steppenadler | [ES] Aguila nipalense | [IT] Aquila delle steppe | [NL] Steppearend



Characteristics
Size and form close to Imperial Eagle but bill smaller, while shape of extended wing differs in shorter inner primaries and hence more bulging secondaries. Plumage basically dark brown, somewhat paler below especially on throat; flight and tail feathers normally grey and barred overall unlike Imperial Eagle. Lacks pale nape, but often pale patch on back and on bases of primaries. Yellow gape extends backwards to point below all of eye. Juvenile noticeably paler than adult, with upper wing and tail base patterns recalling Imperial Eagle, Lesser Spotted Eagle and Spotted Eagle but distinguished from all by striking whitish band on largest under wing-coverts (prominent until 2nd or 3rd year).
Although powerful, shares flight attitudes and action, often somewhat ragged look, and piratical behaviour with Tawny Eagle. Separation from Imperial Eagle incompletely studied but tail pattern may also be helpful, apparently always evenly barred in Steppe Eagle but with broad black terminal band at least on adult Imperial Eagle.
