Oropéndola alinegra Oriolus nigripennis

A large oriole found primarily in secondary and submontane forests. Has a golden yellow body, a black head and throat, a red bill, and red eyes. The wings have uniform black primary flight feathers and some black edging on the secondary flight feathers. The tail is black with yellow feather tips. Easily confused with the co-occurring Western Black-headed Oriole, but note Black-winged Oriole’s solid black primary flight feathers and darker black tail. Voice is a varied series of whistles and liquid “tlee-o-yup!” calls.
