Prigogine's Greenbul Chlorocichla prigoginei

A large, richly colored greenbul, yellow-olive on the back and yellow below, with a gray patch on the face, a white chin, and a red eye. A very poorly known species of the eastern Democratic Republic of Congo, found locally in gallery forest and other forest patches within savanna. Usually in groups. More colorful than other greenbuls that overlap in range. Similar in appearance to Joyful Greenbul, but distinguished by the gray on the face and the white on the chin. Voice unknown, though seemingly less vocal than Joyful Greenbul.
