On Madagascar, vangas were traditionally believed to be a small family of shrike-like birds. Recent research suggests that several Madagascan taxa most similar in appearance and habits (and formerly considered to be) Old World warblers, Old World flycatchers or Old World babblers may be vangas. Yamagishi "et al." found in 2001 that "Newtonia" appeared to belong with the vangas rather than the warblers and also that "Tylas" was a vanga and not a bulbul. It also appears that Ward's flycatcher and Crossley's babbler belong with the vangas.
