Vangidae or vangas, is a genus of little-known small to medium-sized passerines restricted to Madagascar and the Comoros. There are about 22 species, depending on taxonomy. Most species are shrike-like, arboreal forest birds, feeding on reptiles, frogs and insects. Several other Madagascan birds more similar to Old World warblers, Old World babblers or Old World flycatchers are now often placed in this family. Vangas differ greatly in bill shape and have a variety of foraging methods. Their stick nests are built in trees. They do not migrate.
