Wahlberg’s eagle is a plain, medium-sized bird of prey with the distinction of probably being the most common eagle in Africa (2) (4). Although usually dark brown, its plumage can vary a great deal, with some morphs being almost pure white in appearance (5) (6). In flight, this eagle can be readily identified with its long, straight-edged wings and long square tail, likened to one narrow and one wide plank crossing at right angles (5) (6) (7). The head has a slight crest and the legs are entirely feathered, a feature common to all true eagles (6) (7). Immature Wahlberg’s eagles are identical in appearance to the adults (7).
In accordance with a large geographical distribution, Wahlberg’s eagle occurs in a wide range of habitats from woodland to areas of cultivation (5)
Wahlberg’s eagle is a migratory species with many birds moving southwards from north of the equator to breed during the summer months (4) (7). The courtship flights are noisy but relatively brief and rarely involve more than the male and female circling each other. Nests are fairly small and are constructed in the canopy of a tall tree such as a baobab, acacia or eucalyptus. Normally just a single egg is laid which is incubated for around 45 days before hatching.
Hunting on the wing, Wahlberg’s eagle takes a varied diet of reptiles, small to medium sized birds and small mammals in roughly equal proportions (2) (7). In some areas it will occasionally catch other animals such as amphibians and insects and is known to steal food from the long-crested eagle (2).
There are no known conservation measures currently in place for Wahlberg’s eagle.
The Smithsonian Institution's Monitoring and Assessment of Biodiversity Programme and Shell are working together to increase understanding of biodiversity and energy resource development in Gabon. |
