Ayres's hawk-eagle Range |
Ayres's hawk-eagle (Hieraaetus ayresii), also referred to as Ayres' eagle,[2] is a medium-sized bird of prey in the family Accipitridae. It is native to African woodlands. Its name honors South African ornithologist Thomas Ayres.[3]
Description and Behavior
This relatively small eagle has a total length of 46 to 55 cm (18 to 22 in).[2] It usually weighs 685 to 1,045 g (1 lb 8.2 oz to 2 lb 4.9 oz); but may exceed 1,262 g (2 lb 12.5 oz). The female is larger and heavier than the male.[4] In one study, the wingspan of two individuals averaged 124 cm (49 in).[5] Ayres's hawk-eagle has a long, barred tail and relatively narrow wings. The adult plumage is predominantly black/brown, with heavily streaked white underparts; in some individuals, the underparts are much paler. Adults typically have a pronounced white shoulder where the leading edge of the wing meets the body (the carpal joint). The immature is drab and paler.
The Ayres's hawk-eagle hunts small mammals like rabbits and mice.
Distribution and Habitat
Ayres' eagle is an uncommon resident of non-arid Sub-Saharan Africa, and a non-breeding summer migrant to the far south of its range (South Africa; southern Zimbabwe, Mozambique).[2][6] It appears to prefer dense woodland and forest edges.[4]
Although an uncommon bird throughout its range, it is classified as Least Concern (LC) by the IUCN, due to its large range and its numbers - while small - appearing stable at the present time.
