https://en.wikipedia.org/wiki/African_golden_oriole

Typical Old World oriole with mostly yellow plumage and a red bill. Note the small black mask around the eye and the black wing that is heavily edged in yellow. Male is brighter yellow than female. Found in thick woodland and some forests. Song is a series of liquid whistles. Common call is an upslurred mew. Similar to Eurasian Golden Oriole, but the wing feathers have yellow edging, and the black face mask extends well behind the eye.
