- Ploceus nigricollis
Includes: Olive-naped Weaver
Identification
15–17 cm (6-6¾ in)
Male (nominate race)
- Blackish upperparts and wings
- Yellow underparts
- Head golden with chestnut wash
- Black eyemask and bib
- Pale yellow iris
- Strong conical bill
Female (nominate race)
- Blackish crown, upperparts and wings
- Yellow underparts and eyebrow
- Black eye-stripe but no bib
Both males and females of subspecies brachypterus (from western Cameroon west to the Gambia) have olive-green backs.
Similar Species
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])
Subspecies
Clements recognises the following subspecies [1]:
- P. n. brachypterus: "Olive-naped Weaver" Senegal to Nigeria and western Cameroon; winters in Bioko
- P. n. nigricollis: Eastern Cameroon south to northern Angola and southern Democratic Republic of the Congo, east to extreme southern South Sudan, Uganda, western Kenya, and northwestern Tanzania
- P. n. melanoxanthus: Southern Ethiopia to eastern Kenya and eastern Tanzania
Habitat
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.
