The Harrier Hawk, African Harrier Hawk or Gymnogene (Polyboroides typus) is a bird of prey that is related to the harriers. The only other member of the genus is the allopatric Madagascar Harrier Hawk.
The Harrier Hawk is a medium-sized raptor that is about 60-66cm in length.
The upperparts, head and breast are pale grey. The belly is white with fine dark barring. The broad wings are pale grey with a black trailing edge fringed with a narrow white line. The tail is black with a single broad white band. There is a bare facial patch of variable colour.
Males and females look alike, but young birds have pale brown instead grey, and dark brown replacing black.
Breeding / Nesting
It breeds in most of Africa south of the Sahara.
Its habitat is woodland preferably with palm trees and often near water. It builds a stick nest in the fork of a tree or the crown of a palm tree.
The clutch is one to three eggs.
Diet / Feeding
The Harrier Hawk is omnivorous, eating the fruit of the Oil Palm as well as hunting vertebrates.
A comparable leg-structure and behavior can be found in the Neotropical Crane Hawk; a case of convergent evolution.
