The Chestnut and Black Weaver is native to West Africa, from Sierra Leone to Nigeria.
The male is black with chestnut plumage on his back and belly. They were previously classed as a subspecies
of the wholly black Vieillot's Black Weaver but have recently been split out as a separate species.
Like most other weaver birds, the male constructs a suspended woven-grass nest to attract a female.
Like other weavers, the female has more sparrow-like cryptic brown plumage, including a brown rather than black head.
