Odd and unique member of the waxbill family. Males are yellow and olive-green with a black head; females are olive-green. Both sexes have a pink bill. Males vary geographically in how yellow or olive-green their back is, how much orange they show below, and whether or not they have a yellow collar. Found in and around montane forest, usually in pairs or small groups. Quiet and inconspicuous bird. The call is a sharp “tsik.” Males have a similar pattern to some weavers but are separated by their pink bill. Also similar to orioles, but much smaller.
