The Harrier Hawk is omnivorous, eating the fruit of the Oil Palm as well as hunting vertebrates.

Its ability to climb, using wings as well as feet, and its long double-jointed legs, enable this bird to raid the hole nests of barbets and woodhoopoes for fledglings.

A comparable leg-structure and behavior can be found in the Neotropical Crane Hawk; a case of convergent evolution.


Calls / Vocalizations

The call is a whistled sueee-sueee-sueee.
