This is a medium-sized bulbul, actually exactly as large as the (very) Common bulbul (18 cm). It occurs sparingly and is limited to East Africa. In mountain areas between 1,350-3,300 m, such as Mount Kenya, however, it is not uncommon and not so difficult to see (or photograph). In the picture, we see most of the typical features: the green underside, the gray head with a broken, white eye ring. However, the black 'crown', which has given it its name in Swedish not clearly distinguishable. The species subsits on fruits, flowers, spiders, beetles and other insects. (The classification in relation to the subspecies and other closely related species is unusually tricky...)
