The black-necked weaver (Ploceus nigricollis) is a resident breeding bird species in much of tropical Africa from Senegal and northern Angola, South Sudan and Tanzania. The adult male has a black eyemask and bib, olive upperparts and wings, and yellow underparts and head. The Black-necked Weaver was formally described by Louis Jean Pierre Vieillot, a French ornithologist. This species had been collected by Jean Perrein, a French naturalist, who travelled in Africa and on other continents. Vieillot was interested in the habits of living birds, but Perrein did not provide any field notes for the Black-necked Weaver, as he had done for the Crested Malimbe. Vieillot also gave a French name to this species – Le Tisserin a gorge noire (meaning Weaver with a black throat). It builds a large coarsely woven nest made of grass and creepers with a 15-20 cm downward facing entrance tunnel hanging from the globular egg chamber. The nest is suspended from a branch in a tree and 2-3 eggs are laid. It nests in pairs but forms small flocks when not breeding.
