| Ploceus nigricollis (Vieillot, 1805) |
The Black-necked Weaver (Ploceus nigricollis) is a resident breeding bird species in much of tropical Africa from Senegal and northern Angola east to southern Sudan and Tanzania.
This weaver occurs in forests, especially in wet habitats. It builds a large coarsely woven nest made of grass and creepers with a 15cm 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.
The Black-necked Weaver is a stocky 16cm bird with a strong conical bill. The adult male of the northern race has olive upperparts and wings, and yellow underparts and head. It has a black eyemask and bib, and a pale yellow iris. The non-breeding male has a yellow head with an olive crown, grey upperparts and whitish. The wings remain yellow and black.
The adult female also has olive upperparts and wings, and yellow underparts and head. It has a black eyemask but no bib.
The southern race found from Nigeria eastwards has a quite different appearance, with almost black upperparts and tail.
The Black-necked Weaver feeds on insects and vegetable matter. The calls of this bird include a wheezing dew-dew-twee .
