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 ([1][2]).

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.[3]

Systematics

A review of new DNA sequence data (Jønsson & Fjeldså 2006) suggests the genus might not be monophyletic. Few species have been researched, however, with the highest density of sampled taxa being from Micronesia. There, it appears, a more distinct eastern lineage and a western one closer to East Asian species occur. The relationships of the former to the Rukia white-eyes need investigation.
