The African Goshawk is a relatively large African hawk, the largest next to the Black Hawk. Its plumage is very variable, even within a single subspecies, with variations mainly in the background colour and the extension and colour of the bars on the lower parts. This species displays the pronounced sexual dimorphism found in Accipiter. The female is a third bigger than the male.
Typically, the adult male has steel-grey upperparts and finely barred underparts in grey-brown, reddish-brown and even bright red against a white or reddish background. Its eyes are yellow, the cere on its beak is not bright yellow as in other hawks, but yellow-green, yellowish or even grey-green. The tail is dark grey with some distant pale grey bars and sometimes white in the centre. The legs are yellow. Some males have russet or red flanks, with no stripes.
The female has dark brown upperparts and its underparts are heavily barred in brown against a white background. Its cere is the same as the male's.
The immature bird resembles the female, but its underside, instead of being barred, is heavily speckled with brown on a pale background, and the eyes are brown.
There is a melanistic, entirely dark form of this species with pale bars on the upper tail and in flight contrasts between its pale primary remiges and dark coverts.
The race pembaensis is smaller, pale grey above and reddish or rosy-red underneath.

Voice song and cries

Autour tachiro
adult

The call is a sharp tchouit that resembles the sound of a kiss, and is emitted most often during aerial courtship displays.

Habitat

The African Goshawk frequents all types of forested habitats, deciduous or evergreen forests, up to 3,000 meters in altitude, riparian woodlands, wooded savanna, mangrove, and plantations.

Behaviour character trait

Autour tachiro
♂ adult

The African Goshawk, like other hawks, hunts by waiting and hiding in dense vegetation. It often stays still throughout the day, preferring to hunt at dawn and sunset. It can hunt by circling above the canopy, and even by making short pursuits through the undergrowth. At the time of the mating display, it performs long circular flights at a high altitude above the forest it occupies.

Dietfeeding habits

Autour tachiro
♀ adult

The African Goshawk primarily feeds on small birds that it captures in the air and at the nest, as well as on bats and rodents. It can also hunt small reptiles, squirrels, frogs, and invertebrates.

Reproduction nesting

♀ juvenile

The nest is a well-hidden platform of twigs in the canopy. Clutch usually consists of two or three eggs, incubated for 30 to 35 days. The chicks are covered in white down and leave the nest after about 5 weeks.

Geographic range

Autour tachiro
immature

The African Goshawk is present in East Africa, from Southern Somalia and Uganda to the north, down to the Cape in the south, along the coast. At the latitude of Mozambique, its range expands westward to cover the entirety of Zambia and Zimbabwe, a large part of Angola and the south of the Democratic Republic of Congo.

The African Goshawk, which knows how to adapt to any forest environment, including secondary forests and plantations, is one of the most common hawks in African forests. Therefore, the species, which does not seem to be affected by pesticides, is not currently facing global threats. However, an acceleration of deforestation would of course represent a real threat.
