Palmnut Vulture (Gypohierax angolensis)



The Palmnut Vulture is a vulture and monotypical to the Gypohierax genus. As a vulture it comes across as rather smallish, sized only between 57-65 in length and a wingspan of only 133-155.


Acutally, size is noth the only thing making this vulture the odd one out. The reason for being special simply is its diet. This vulture mostly feeds on the fruits of the palm oil tree and only to a much lesser degree on fish, crabs and amphibians. Though it does not feed on carcases or carrion as the larger vultures usually do.

In Sub-Saharan Africa: Senegal and Gambia (Senegambia) to south Mali, central Nigera and southernmost Chad, from Sudan southwards to Angola, Zambia, Mozambique; extreme northeastern South Africa (Zululand); east Kenya and northeast Tanzania, Pemba and Zanzibar.


Movements: Always moves to rich food grounds, otherwise adults are sedentary. Immature are nomadic


Habitat: Forests, tall woodland, mixed forest, cultivation of oil and raffia palms; streams, rivers, lakes, oil-palm plantations. Requires waterside natural forests to breed. Also in wooded savannah without direct access to water. Does not approach larger settlements but allows humans to approach closely. Up to sealevels of 1,500 m.


Behaviour: Mostly feeding directly from palm oil trees, otherwise search flights to find food.
