Polemaetus bellicosus
Nairobi National Park, Kenya. Oct. 2016.
From Wikipedia: The martial eagle is a very large eagle, with an average length of 78–96 cm. The adult's plumage consists of dark grey-brown coloration on the upperparts, head and upper chest, with slightly lighter edging to these feathers. The body underparts are white with blackish-brown spotting. The underwing coverts are brown, with pale flight feathers being streaked with black. The female is usually larger and more spotted than the male. Martial eagles have a short erectile crest, which is often not prominent.
