Habitat preferences among weaver species vary as much as their appearance and behavior. Most prefer open spaces, like grassland with or without scattered trees. The red-billed buffalo-weaver prefers savanna with acacia or baobab trees in east Africa, but is even more partial to areas disturbed by natural forces, such as wild animal herds, or human activities. Some species prefer living close to villages, probably for protection from predators that naturally fear humankind. If the people of the village abandon it, the weavers will desert their nest.

Many weaver species change habitats in the breeding season. The thick-billed weaver, during its breeding season, lives in spreads of grasses, reeds, and papyrus in marshes and rivers. During nonbreeding periods of the year, the species returns to tropical forest.
