Abyssinian Long-eared Owl - Asio abyssinicus

Also known as African Long-eared Owl

Introduction: The Abyssinian Long-eared Owl is a medium-sized owl with long wings and prominent dark ear-tufts.

[For help with terms used in the description, see parts of an owl. For general characteristics common to most owl species, see owl physiology.]

Description: The facial disc is tawny-brown, with a blackish-brown rim. Eyes are orange-yellow. The cere is greyish-brown, and the bill is blackish. Ear-tufts are dark, and set close to the centre of the forehead.
Upperparts are dark golden-brown, mottled tawny. The outer webs of the scapulars are whitish, forming an indistinct row across the shoulder. Flight feathers are distinctly barred light and dark. The tail is greyish-brown, with broad dark bars.
Underparts are mottled and broadly streaked tawny and dark brown on the upper breast. The rest of the underparts are tawny with distinct shaft-streaks and cross-bars, dividing the the large buffish-white parts of the feathers into square blocks, giving a checkered effect.
Tarsi and toes are feathered, and the claws are blackish-horn.

Size: Length 40-44cm. Wing length 309-360mm. Tail length 182-190mm. Weight 245-500g. Females are slightly larger than males.

Habits: The Abyssinian Long-eared Owl is a nocturnal bird, roosting during the daytime usually on a branch close to a tree trunk, or sometimes in groves of giant heath. Sometimes several owls may roost together.

Voice: The song of the male is a deep, drawn-out, disyllabic "who-woohm", rising slight in pitch and repeated at intervals of several seconds The female has a similar, but slightly higher-pitched and softer song. Barking notes are uttered when alarmed. A high squeal may be a begging call.

Hunting & Food: Feeds mostly on small mammals, but also other small vertebrates and insects. Hunts often on the wing, sometimes hovering over potential prey before snatching them. Also hunts from a perch.

Breeding: The Abyssinian Long-eared Owl is territorial. Males claim their territory by singing. Normally breeds in stick nests of larger birds. The breeding biology of this bird is little studied, but probably similar to the Long-eared Owl.

Habitat: Giant heath, open grassland and moorland with groups of trees, forested areas in highlands, humid forested valleys and gorges in high mountains from about 2800-2900m.

Distribution: Ethiopian Highlands, Mt. Kenya, Ruwenzori Mountains, western Uganda, south to eastern Zaire.
