Distribution / Range

The Crested Serpent Eagle can be found in a large geographical region from South Asia, including Pakistan, India, and Sri Lanka, to Southeast Asia, extending to southern China and Indonesia.

Description

The Crested Serpent Eaglesis a medium-large raptor at about 55–75 cm in length. Adults have dark brown upperparts and head and have a hooded appearance at rest. The underparts and underwing coverts are pale brown.

In soaring flight, the broad wings are held in a shallow V. The tail and underside of the flight feathers are black with broad white bars.

When perched, they appear large-headed and owl-like due to the shape of the face and positioning of the eyes. They do not have feathers on their legs.

Sexes are visually similar, but young birds have a whitish head, underparts, and underwing, the latter showing darker barring.
