About These Birds
Vulturine Guineafowl
The world's largest guineafowl (~1.3 kg) of family Numididae, with a bare blue head, chestnut nape, and brilliant cobalt-blue breast streaked with white. Inhabits dry bushland and thornscrub in northeastern Africa from Somalia to Tanzania. Forages in large coordinated flocks for seeds, berries, and invertebrates. Least Concern; a striking bird of the semi-arid Horn of Africa.
Black Guineafowl
A medium-sized guineafowl (~700 g) of family Numididae, with entirely black plumage and a bare red head and neck. Inhabits lowland rainforest understory in the Congo Basin of central Africa. Forages in small flocks on the forest floor for insects, seeds, and small invertebrates. Least Concern; associated with primary forest but broadly distributed across the Congo rainforest.
