Quelea

Quelea () is a genus of small passerinebirds that belongs to the weaver family Ploceidae, confined to Africa. These are small-sized, sparrow- or finch-like gregarious birds, with bills adapted to eating seeds. Queleas may be nomadic over vast ranges; the red-billed quelea is said to be the most numerous wild bird species in the world and is a major pest to small-grain cereal crops in much of sub-Saharan Africa.
