Theoriole warbler (Hypergerus atriceps) is a large warbler in the familyCisticolidae, and theonly member of thegenusHypergerus. Thisbird is a resident breeder in westAfrica from southernSenegal toCameroon.
This skulkingpasserine is typically found in dense thickets usually near water. The oriole warbler builds a large untidynest suspended frompalm leaves.
These 20-cm long warblers have a long tail, strong legs and a long blackbill. At a weight of around 30 g (1.1 oz) the oriole warbler may be the largest of the species-richCisticolidae family.[2] 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 yelloworioles. The sexes are similar, but juveniles are duller.
Like most warblers, the oriole warbler isinsectivorous. Thesong is a loud whistledduettedtoooo-ooo-eee-oooo, oooo-ooo-eee-oooo. The male always leads the duet[3] and the female answers, though this is done in a manner that is temporally rather loose.[4]
