| Hypergerus atriceps (Lesson, 1831) |
The Oriole Warbler, Hypergerus atriceps, is a small warbler, the only member of the genus Hypergerus. This bird is a resident breeder in west Africa from southern Senegal to Cameroon and north Zaire.
This skulking passerine is typically found in dense thickets usually near water. Oriole Warbler builds a large untidy nest suspended from palm leaves.
These 20 cm long warblers have a long tail, strong legs and a long black bill. Adults are light olive above, yellow below and have a black hood. The species' name refers to their resemblance to the unrelated but similarly black and yellow orioles. The sexes are similar, but juveniles are duller.
Like most warblers, the Oriole Warbler is insectivorous. The song is a loud whistled duetted toooo-ooo-eee-oooo, oooo-ooo-eee-oooo.
