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".
Red-billed quelea during flooding. It needs shrubs, reeds or trees to nest and roost. Red-billed queleas migrate seasonally over long distances in anticipation of the availability of their main natural food source, seeds of annual grasses. The presence of these grass seeds is the result of the beginning of rains weeks earlier, and the rainfall varies in a seasonal geographic pattern. The temporarily wet areas do not form a single zone that periodically moves back and forth across the entirety of Sub-Saharan Africa, but rather consist of five or six regions, within which the wet areas "move" or "jump".
