Project Description

Animal Name: African Harrier Hawk
Scientific Name: Polyboroides typus

Habitat: It generally prefers savanna woodland, such as Acacia, miombo (Brachystegia) and mixed-species woodland, as well as forest edges, wooded cliffs, ravines and other rocky habitats, tall trees along drainage lines, Eucalyptus plantations and tall trees in gardens.

Distribution: Occurs across much of sub-Saharan Africa; in southern Africa it is locally common in Zimbabwe, Mozambique, northern and eastern Botswana, northern Namibia (including the Caprivi Strip) and eastern and southern South Africa.

Diet: It mainly eats birds and their eggs, reptiles and small mammals, using a wide variety of foraging techniques. It specialises in using its long legs to extract food from crevices and cavities, such as in the tree canopy or the ground, often stealing eggs and chicks from weaver nests, or the more easily accessible nests of other birds (without entrance tunnels). It also hunts by soaring high in the sky and rapidly descending once it has spotted prey, sometimes scavenging for roadkills and raiding nests in suburban gardens.

Reproduction:

Usually a monogamous, highly territorial solitary nester, although three adults were once recorded at one nest.
The nest is built by both sexes in about 30 days, consisting of a platform about 75 cm wide and 20 cm deep, made of sticks and thickly lined with green leaves. It is typically placed in the upper branches of a tree, in a cave or between the base of a bush and a cliff; it also uses the nests of other birds, such as Black Sparrowhawk and Martial Eagle.
Egg-laying season is from August-December, peaking from September-November.
It lays 1-3 eggs which are mainly incubated by the female for about 35-36 days, while the male provides food to her at the nest.
The chicks are fed by the male and brooded constantly by the female for the first week of their lives, after which she remains near the nest to protect them. The older chick sometimes kills its younger sibling, even if it is fully fed and supervised by an adult. The young leave the nest at about 45-55 days old, remaining partially dependent on their parents for at least another 10 days.
