[edit] Taxonomy

There are five subspecies, with variation in size, colour of the underparts, and the pattern on the underparts and tail.

• Accipiter tachiro tachiro is found in South Africa, Swaziland and Mozambique south of the Limpopo
• A. t. sparsimfasciatus is from north-eastern Namibia, the extreme north and north-east of Botswana, Zimbabwe, Democratic Republic of Congo, Angola, Somalia, Tanzania and Mozambique north of the Limpopo
• A. t. unduliventer is from Eritrea and Ethiopia
• A. t. croizati is endemic to Ethiopia
• A. t. pembaensis is endemic to Tanzania

[edit] Habitat

Forest, plantations, and closed riverine woodland.

[edit] Behaviour

The African Goshawk is usually inconspicuous, but its presence is often betrayed by its call which is often given when circling high above the forest, but is also given by birds perched in the canopy of large trees.

[edit] Diet

Prey comprises mainly birds (usually bulbul size or smaller), but includes small mammals. Hunting is usually done using a quick dash from a perch in cover, and birds are caught both in flight and on the ground.
