Akun eagle-owl

The Akun eagle-owl is a species of owl native to the African tropical rainforest, specifically found in countries bordering the Gulf of Guinea. It is distinguished by its relatively small size for an eagle-owl, predominantly dark to reddish-brown plumage with white markings, and a diet that primarily consists of insects.

About Akun eagle-owl

The Akun eagle-owl (Ketupa leucosticta) is a species of owl belonging to the Strigidae family, native to the tropical rainforests of Africa. Formally described in 1855 by Gustav Hartlaub from a specimen collected in Ghana, its specific epithet, 'leucostictus,' derives from Ancient Greek meaning 'white-speckled.' It is now classified within the genus Ketupa.

Description and Appearance

This owl is considered one of the smaller eagle-owls, measuring between 40–46 cm in length. Males typically weigh between 486–536 g, while females are slightly heavier, ranging from 524–607 g. Its plumage is predominantly dark to reddish-brown on the head and upperparts, with dusky brown bars on the wings and back, and distinctive white markings on the shoulders. A notable feature is the presence of two large, dark brown ear tufts, each marked with white spots. The eyes are pale yellow. The upper breast exhibits a light reddish-brown color with dark barring, contrasting with the white lower breast, belly, and vent, which are marked with reddish-brown vermiculations and prominent blackish spots. Juvenile owls are distinguished by a whitish head and body, accompanied by reddish-brown barring and brown wings and tail.

Distribution and Habitat

The Akun eagle-owl has a fragmented geographic range that spans several West African countries bordering the Gulf of Guinea. Its distribution extends from Guinea eastward to Cameroon and southward to Angola, with extensions inland into the southern Central African Republic, Congo, and the northern parts of the Democratic Republic of Congo. The species primarily inhabits lowland primary and secondary rainforests. It shows a preference for areas around forest edges and clearings, as well as the banks of rivers and forested river islands.

Behavior and Ecology

Like most owls, the Akun eagle-owl is a nocturnal species, emerging from its daytime roost at dusk to hunt. A unique characteristic for an eagle-owl is its diet, which appears to consist almost exclusively of insects. Its relatively small feet and a weaker bill suggest adaptations for this specialized prey, preventing it from tackling larger animals. Its main food sources include beetles, cicadas, and locusts, which it captures either by gleaning them from foliage or by intercepting them in flight. Prey is typically brought back to a perch, held in the feet, and then torn into smaller pieces with the bill.

Details regarding the breeding biology of the Akun eagle-owl are limited. However, in West Africa, egg-laying seems to occur between November and January. Young owlets have been recorded in nests in Liberia from February to April, indicating a potential breeding period. In common with some other eagle-owls, the Akun eagle-owl constructs its nest on the ground. The typical call is a low, accelerating, clucking rattle, and it can produce an unusual quacking sound when alarmed.
