Little sparrowhawk description

Aptly named for its tiny size, the little sparrowhawk is also readily distinguished by the two white spots on the upperside of its central tail feathers, which contrast with the dark upperparts, and by a white bar on the rump ^{(2) (3) (5)}. The male has dark grey upperparts, a white throat, and white underparts with fine reddish-brown barring, while the female is larger and dark brown above, with broader brown bars below ^{(2) (3)}. The eye and cere are yellow, the beak black, and the long legs and feet are yellow. Individuals have a variable amount of reddish-brown on the flanks, which is more notable in males ⁽³⁾. The juvenile is browner than the adults, and has large, round spots on the underparts, as well as a slightly paler cere ^{(2) (3)}.

The little sparrowhawk is quite a secretive bird, often overlooked or confused with other, similar hawks, particularly the similar but darker red-thighed sparrowhawk (Accipiter erythropus) and the African goshawk (Accipiter tachiro), which is larger, with stouter legs and toes, and has a dark rump and grey cere. The adult male African goshawk shares the little sparrowhawk’s white tail spots, but lacks the latter’s pale rump ^{(2) (3) (5) (6)}. The calls of the little sparrowhawk include a high-pitched kek-kek-kek-kek, given by the male, and a softer kew-kew-kew, given by the female ⁽⁵⁾.

Also known as

African little sparrowhawk.

French

Epervier minule.

Little sparrowhawk biology

This small hawk flies with a fast, swerving flight and is quick and agile in the air, taking most prey on the wing after short dashes from cover. The diet consists mainly of small birds, although some bats, lizards and insects are also taken ^{(2) (3)}. Some prey is pursued to the ground ⁽²⁾.

The breeding season of the little sparrowhawk varies with location, ranging from March to April in north-eastern Africa, to October to November in western Kenya ⁽²⁾, and September to February in southern Africa ⁽⁶⁾. The nest is small, and built from a platform of sticks, often well hidden in a high fork of a tree and lined with fine twigs and green leaves ^{(2) (3)}. Clutch size ranges from 1 to 3 eggs (usually 2), which hatch after an incubation period of 31 to 32 days, the young fledging at 25 to 27 days old ^{(2) (8)}.

Little sparrowhawk range

The little sparrowhawk is widespread in eastern, central and southern Africa, from southern Sudan and Ethiopia, south to South Africa, and west to Angola and Namibia ^{(2) (3) (6) (7)}.

Little sparrowhawk habitat

This species inhabits patches of woodland and forest, typically along rivers or in valleys. It also uses exotic tree plantations, which has allowed it to colonise drier, more open savanna areas ^{(2) (3) (5) (6)}.

Little sparrowhawk status

Classified as Least Concern (LC) on the IUCN Red List ⁽¹⁾ and listed on Appendix II of CITES ⁽⁴⁾.

Little sparrowhawk threats

The little sparrowhawk has a large range and is still relatively common, even in small patches of habitat and in wooded urban habitats. It has also adapted to exotic plantations, allowing it to expand its range, and is not currently considered at risk of extinction ^{(2) (6) (7)}. It may potentially be vulnerable to contamination by pesticide residues, which may accumulate in its prey ⁽⁶⁾, but this is not currently known to be a threat ⁽²⁾.

Little sparrowhawk conservation

The little sparrowhawk is listed on Appendix II of the Convention on International Trade in Endangered Species (CITES), meaning that any international trade in the species should be carefully monitored ⁽⁴⁾. However, there are no other specific conservation measures currently in place for this widespread bird of prey.
