Gerygone, the gerygones or peep-warblers, is a genus of bird in the Acanthizidae family. The genus ranges from Southeast Asia through New Guinea and Australia to New Zealand and the Chatham Islands. Most of the species are found in Australia and New Guinea; only one, the golden-bellied gerygone, has managed to cross Wallace's Line and colonise as far as Thailand, Malaysia and the Philippines. Their songs are described as "simple but delightful", many descending in pitch, and some species are excellent mimics. "Gerygone" means "born of sound" (Magrath 2003).
