- Ploceus nigricollis
Identification
16cm
Male (northern race)
- Olive upperparts and wings
- Yellow underparts and head
- Black eyemask and bib
- Pale yellow iris
- Strong conical bill
Non-breeding male
- Yellow head
- Olive crown
- Grey upperparts and whitish
- Yellow and black wings.
Female
- Olive upperparts and wings
- Yellow underparts and head
- Black eyemask but no bib
Subspecies brachypterus (from western Cameroon west to the Gambia) and po (Bioko) have olive-green backs. The nominate subspecies (from Cameroon east and south) is black-backed.
Similar Species
The green-backed subspecies (see Taxonomy below) should be separated with care from the Spectacled Weaver where both occur (eastern Nigeria and western Cameroon). This species shows more olive and less yellow on the head (especially the crown area in females) and a thicker bill.
