The West African chestnut-and-black weaver (Ploceus castaneofuscus) males have a black plumage with chestnut patches on their back and belly. Females are brownish-olive. They breed in colonies, with males defending territories and building nests, often mixed with other weaver species like the Village Weaver. The males weave intricate, oval nests using strips of palm leaves or grass, with the nest having a rough exterior and an entrance below.
