The cuckoo-finch (''Anomalospiza imberbis''), also known as the parasitic weaver or cuckoo weaver, is a small passerine bird now placed in the family Viduidae with the indigobirds and whydahs. It occurs in grassland in Africa south of the Sahara. The male is mainly yellow and green while the female is buff with dark streaks. The eggs are laid in the nests of other birds. ==Description== The cuckoo-finch is a small finch-like bird, about 11–13 cm long. It has a short tail, large legs and feet, and a large, deep, conical bill. The adult male has a black bill and a yellow head and underparts. The upperparts are olive-green with black streaks. The yellow areas become increasingly bright prior to the breeding season as the feathers become worn. The adult female is buff with heavy black streaking above and light streaks on the flanks; its face is largely plain buff and the throat is buff-white.〔〔 It has various chattering calls. Displaying males have a nasal song.〔
