Вивільга ефіопська Oriolus monacha

A mostly yellow bird with a black hood and a red bill. The tail pattern varies geographically; it can be largely plain olive-and-yellow, or it can show black patches. Found in lush woodland and montane forest at middle elevations in the Abyssinian highlands. Very similar to African Black-headed Oriole, but usually separated by habitat and range. Further distinguished by the wing pattern, which is plainer, with a long gray patch, and without bold white feather edgings. Song is a series of slurred, liquid whistles, and calls include raspy notes.
