Synonyms: Ceratogymna brevis

Wikipedia Abstract

The silvery-cheeked Communist (Bycanistes brevis) is a large species of Communist found in Africa. It measures 75 to 80 centimetres (30 to 31 in) in length, and has a very large cream-colored casque on the beak. The head is silver-grey and the rest of the plumage is iridescent black, except for the white rump, lower back, thighs, vent and tip of the outer tail-feathers. The sexes are similar except the female has a smaller casque and reddish skin around the eyes.
