Widely distributed in Africa south of the Sahara in woodland, forest, alien plantations and wooded urban areas. Makes its presence known in an area by taking early morning flights high above the ground and emitting its clicking call (like two stones hit together at 2-3 second intervals). Preys mainly on birds (up to the size of francolins and domestic chickens and including nestlings) but also on small mammals (bats, squirrels, mice) and lizards. More rarely feeds on snakes, frogs, earthworms and insects.

Distribution and habitat

Occurs from Ethiopia and Eritrea, south through Kenya, Uganda, Tanzania, southern DRC, Zambia, Malawi and Angola to South Africa. In southern Africa, it is scarce to locally common in north-eastern Namibia (including the Caprivi Strip), Zimbabwe, Mozambique and South Africa. It generally favours forest, suburban areas and stands of alien trees, such as Acacia in the Western Cape.

Distribution of African goshawk in southern Africa, based on statistical smoothing of the records from first SA Bird Atlas Project (© Animal Demography unit, University of Cape Town; smoothing by Birgit Erni and Francesca Little). Colours range from dark blue (most common) through to yellow (least common). See here for the latest distribution from the SABAP2.  

Predators and parasites

Movements and migrations

Resident and largely sedentary, although juveniles disperse from their parents territory when they become fully independent.

Food 

It mainly eats birds, supplemented with mammals and lizards, doing most of its hunting from perches concealed by dense vegetation so that it can ambush its prey. Pairs rarely hunt cooperatively at large aggregations of animals, such as bat roosts. The following food items have been recorded in its diet:

Breeding

  • Monogamous, territorial solitary nester, performing a courtship display in which either the male, female or both of them together fly in an undulated flight while calling loudly, sometimes finishing with a steep dive.
  • The nest is built mainly by the female, consisting of a stick platform thickly lined with green leaves, such as pine needles, lichen and mistletoe. It is typically placed on a branch away from the main trunk of a tree, especially if it has dense foliage, although it may also build it on top of an old Hadeda ibis nest, sometimes taking over the nest of a Little sparrowhawk instead of build its own. It has been recorded to nest in the following trees:
    • indigenous trees
      • Acacia
        • A. tortilis (Umbrella thorn)
        • A. nigrescens (Knob-thorn)
        • A. polyacantha (White-stem thorn)
        • A. robusta (River thorn)
      • Combretum imberbe (Leadwood)
      • Kirkia acuminata (White kirkia)
      • Faidherbia albida (Ana-tree)
      • Breonadia salicina (Matumi)
      • Syzygium cordatum (Waterberry)
      • Syzygium guineense (Pointed-leaf waterberry)
      • Diospyros mespiliformis (Jackal-berry)
      • Newtonia hildebrnadtii (Sandveld newtonia)
      • Ficus (figs)
      • Euphorbia cooperi (Bushveld candelabra euphorbia)
    • alien trees
      • Eucalyptus
      • Pinus (pines)
      • Jacaranda acutifolia (Jacaranda)
  • Egg-laying season is from July-December, peaking from September-November.
  • It lays 1-3 eggs, which are incubated mainly or solely by the female for about 35-37 days, while the male feeds her regularly at the nest.
  • The chicks are fed by both parents, leaving the nest after about 30-35 days but remaining in the nest tree vicinity for another six weeks or so. The young become fully independent roughly 1-3 months after fledgling.

Threats

Not threatened, although in Zimbabwe it is threatened by pesticide contamination, while in the Eastern Cape its range has decreased to habitat loss.
