Black-chested Snake Eagle
Circaetus pectoralis
The main identifying character of this bird is its dark brown-black head and chest, to which it owes its name. It is distinguished from the short-toed and Beaudouin's snake eagles by its uniform white lower underparts, in contrast to the darkly blotched belly of the short-toed snake eagle and narrowly barred lower underparts of the Beaudouin's. In flight, the dark head and chest contrast with the lower underparts and underwings, which are both white except for three narrow black terminal bars on the underwings. The sexes are alike in plumage, although the female is appreciably larger.

They can be recognised in the field by their predominantly white underside, the upper parts being greyish brown. The chin, throat and upper breast are a pale, earthy brown. The tail has 3 or 4 bars. Additional indications are an owl-like rounded head, brightly yellow eyes and lightly barred under wing.
