-====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.
