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.

There are 3 subspecies[1]:

  • P. n. brachypterus: (Olive-naped Weaver)
  • P. n. nigricollis:
  • P. n. melanoxanthus:

Race P. n. brachypterus sometimes called "Spectacled Weaver" but that name is now usually restricted to Ploceus ocularis. HBW Alive splits P. n. brachypterus into a separate species called Olive-naped Weaver[3]

Habitat

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