Philippine eagle  (Pithecophaga jefferyi)

The Philippine eagle is the world's largest eagle, and one of the most threatened raptors. The sexes are similar in appearance, possessing a creamy white belly and underwing, whilst the upperparts are a rich chocolate-brown, with a paler edge (4). The long feathers of the head and nape form a distinctive, shaggy crest and are creamy-buff in colour with black streaks (5). Chicks have white down, and juveniles are similar in appearance to adults but have white margins to the feathers on the back and upperwing (6). The heavy legs are yellow with large, powerful claws (5), and the large, deep bill is a bluish-grey (6).
