Zosterops is a genus of birds containing the typical white-eyes. They are traditionally placed in the white-eye family, Zosteropidae, which, however, is now considered part of the Timaliidae .
This genus has the highest number of species among the white-eyes by far. They occur in the Afrotropic ecoregion, the Indomalaya zone, and the Australasia ecozone. Typical white-eyes can reach a length between 8 and 15 cm. Their most characteristic feature is the conspicuous white-feather ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue.
