About Oriolus brachyrynchus Swainson, 1837
The western oriole (scientific name Oriolus brachyrynchus Swainson, 1837) measures 21 centimetres (8.3 in) in length, and weighs 42 to 57 g (1.5 to 2.0 oz). For adult individuals, the upperparts are yellow-olive, the area from the head to upper breast is black, and a small white patch sits on the outer edge of the wings. The beak is brownish pink, the underparts are yellow, and the black tail feathers have broad yellow tips. Juvenile western orioles have olive upperparts and an olive-colored head, with yellow streaking on the throat, a dusky beak, and a black-streaked breast. This species produces a range of fluty vocalizations, including uoo-uoo, uoo-dleeo, tioolioo, whee-whooliu, whoolioo, and too-too-tuloo. These vocalizations normally feature detached notes, and are lower pitched than the calls of the black-winged oriole (Oriolus nigripennis). The western oriole also emits a harsh whit-cheeew-cheeew call. The western oriole is native to African tropical rainforest, specifically found in the rainforests of Sierra Leone, Guinea, Liberia, Ivory Coast, Benin, and Ghana. It occurs either alone or in pairs in the canopies of lowland primary forests, secondary forests, forest clearings with shrubs, and forest edges.
