The bronze mannikin or bronze munia (Spermestes cucullata) is a small passerine (i.e. perching) bird of the Afrotropics. This very social estrildid finch is an uncommon to locally abundant bird in much of Africa south of the Sahara Desert, where it is resident, nomadic or irruptive in mesic savanna or forest margin habitats. It has an estimated global extent of occurrence of 8,100,000 km2. It is the smallest and most widespread of four munia species on the African mainland, the other being black-and-white, red-backed and magpie mannikin. It co-occurs with the Madagascar mannikin on the Comoro Islands, and was introduced to Puerto Rico. Especially in the West Africa, it is considered a pest in grain and rice fields. It is locally trapped for the pet bird trade.
The bronze mannikin is one of the smallest munia species, measuring 9–10 cm in length and weighing 7–12 grams. The adult is a compact bird with a short black tail, and stubby black and pale grey (not distinctly bluish) mandibles. It is black to brownish black on the head, chin, throat and center of the chest, with some purple-green iridescence on the face and sides of the breast. It has greyish brown upper parts and white underparts with irregular barring on the flanks and rump. A small green iridescent patch is present on the outer scapular feathers, besides, especially in the western race, the sides of the lower breast. Wing coverts and remiges are bordered in a paler or warmer tone. The sexes are similar. Immature birds are dun brown above with buff head and underpart plumage. They moult into full adult plumage by age six months, when the males also begin to sing and exhibit breeding behaviour. The race S. c. scutata has barred rather than bronzy green plumage at the junction of the lower breast and flanks. Rump and upper tail feathers only finely barred and almost uniformly dark. These characters are however somewhat variable and unpredictable.
