Red-billed quelea bird "Moineau a bec rouge du Senegal" in French and "Passer senegalensis erythrorynchos" in Latin, both meaning "red-billed Senegalese sparrow". Also in 1766, George Edwards illustrated the species in colour, based on a live male specimen owned by a Mrs Clayton in Surrey. He called it the "Brazilian sparrow", despite being unsure whether it came from Brazil or Angola. In 1850, Ludwig Reichenbach thought the species was not a true bunting, but rather a weaver, and created the genus name "Quelea", as well as the new combination "Q. quelea". The white-faced morph was described as a separate species, "Q. russii".
