Distribution: Afrotropical. SENEGAMBIA, SIERRA LEONE, and GHANA east to ETHIOPIA and south to ANGOLA, northern NAMIBIA, northern BOTSWANA, and northern SOUTH AFRICA. more....

Subspecies: Monotypic.

Taxonomy: May represent an early offshoot of the Eurasian Sparrowhawk (Accipiter nisus group which has become adapted to dry country, and its morphological differences (longer wings, shorter tail and tarsi) may be adaptations related to the habitat differences (Snow 1978).

Movements: Partial migrant and also engages in movements in response to rainfall changes (Bildstein 2006). Movements are poorly understood and complex. It is inexplicably absent seasonally from certain areas, but not in a consistent pattern from one locality to the next. Probably a breeding migrant only to western and eastern Africa and generally resident in the southern portions of its range in southern Africa. more.....

Habitat and Habits: Occurs in savannas and tall deciduous woodlands, including exotic tree plantations (especially in South Africa). Found commonly at the interface between bushveld (savanna) and the highveld grassland in the former Transvaal (Tarboton 1990). Unobtrusive and perches high up on the edge of tall woodland. more....

Food and Feeding Behavior: Feeds mainly on small birds, which it usually captures after fast pursuits. Mostly hunts from an exposed or concealed perch, but also soars at times and stoops at prey, a behavior that Allan and Hustler (1984) described as falcon-like. more....

Breeding: Breeding was recorded from September-January in the Southern Africa Bird Atlas Project, occurring slightly earlier in Zimbabwe than in the former Transvaal (Allan 1997). The small stick nest is placed high in the crown of a large tree. Nesting in patches of tall alien trees, especially gray poplars, has probably greatly expanded its breeding range. This species is displaced from tree plantations by the Black Sparrowhawk. The nest is built by both sexes. The clutch size is usually 3-4 eggs (rarely 2-5). Only the female incubates, and the male provides her with food. more....

Conservation: Rather uncommon in the more northern portions of its range, but widespread and common in many portions of southern Africa. Categorized globally as a species of "Least Concern" by BirdLife International. more....
