Black-chested snake eagle
The black-chested snake eagle (Circaetus pectoralis) is a large African bird of prey in the family Accipitridae. It resembles other snake eagles and was formerly considered conspecific with the short-toed and Beaudouin's snake eagles, to which it is closely related. As well as feeding on snakes, which may be swallowed while still alive, it feeds on lizards, small mammals, frogs and insects. It typically perches in an elevated position ready to swoop silently to capture its prey, before returning to its perch to eat.
