text: The black-chested snake eagle (Circaetus pectoralis) is similar in overall colouring (despite its name it is brown on the chest and the back, being no darker than the adult martial eagle) to martial eagles but is markedly smaller, with a relatively more prominent, rounded head with large eyes, plain, spotless abdomen, bare and whitish legs.
