Subspecies P. n. brachypterus (see Taxonomy below) should be separated with care from the Spectacled Weaver where both occur (eastern Nigeria and western Cameroon). The Black-necked Weaver shows more olive and less yellow on the head (especially the crown area in females) and a thicker bill.

Distribution

Widely distributed in sub-Saharan Africa:
Western Africa: Senegambia, Senegal, The Gambia, Guinea-Bissau, Guinea, Mali, Sierra Leone, Liberia, Ivory Coast, Burkina Faso, Ghana, Togo, Benin, Nigeria, Niger, Cameroon, Central African Republic, Equatorial Guinea, Gabon, Democratic Republic of Congo, Angola
Eastern Africa: South Sudan, Ethiopia, Somalia, Kenya, Uganda, Rwanda, Burundi, Tanzania
African Islands: Gulf of Guinea Islands, Bioko (Fernando Po)

Taxonomy

Subspecies brachypterus is sometimes called "Spectacled Weaver" but that name is now usually restricted to Ploceus ocularis. It may be elevated as "Olive-naped Weaver" (e.g. [3])

Open areas with trees, including forest edges and savanna woodland.

Behaviour

Breeding

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, suspended from a branch in a tree. Two to three eggs are laid.

Diet

The diet includes insects and vegetable matter.

Vocalisation

Call: wheezing dew-dew-twee.
