Weavers belong to the Ploceidae family. They are members of an Old World group, but some have been introduced into North America. They are birds of the sub-Saharan desert in Africa. They are related to Old World Sparrows. They have thick bills for eating seeds. During the breeding season, some males are brightly colored while the females are muted in color. They get their name from weaving plant material into elaborate, covered nests.
