EspañolWHITE-EYE
(Redirected from Zosteropidae)
:''For the fish species known as the white-eye, see White-eye (fish).''
The 'white-eyes' are small passerine birds native to tropical and sub-tropical Africa, southern Asia and Australasia. They also inhabit most of the islands in the Indian and Pacific Oceans (though not Far Polynesia). Many white-eye species are endemic to single islands, and the brown-backed species only occur on islands, but some have a very wide distribution. The Silvereye, ''Zosterops lateralis'', naturally colonised New Zealand, where it is known as the "Wax-eye" or ''Tauhau'' ("stranger"), from 1855.
__TOC__
The birds of this group are mostly of undistinguished appearance, the plumage above being generally either some dull color like greenish olive, but some species have a white or bright yellow throat, breast or lower parts, and several have buff flanks. But as indicated by their scientific name, derived from the Ancient Greek for girdle-eye, around the eyes of many species is a conspicuous white ring. They have rounded wings and strong legs. The size ranges up to 15cm (6 inches) in length.
All the species of white-eyes are sociable, forming large flocks which only separate on the approach of the breeding season. They build tree nests and lay 2-4 unspotted pale blue eggs. Though mainly insectivorous, they eat nectar and fruits of various kinds. The Silvereye can be a problem in Australian vineyards, through piercing the grape allowing infection or insect damage to follow.
The white-eyes were long considered a distinct family 'Zosteropidae' because they are rather homogenous in morphology and ecology, leading top little adaptive radiation and divergence.
The genus ''Apalopteron'', formerly placed in the Meliphagidae, was transferred to the white-eyes on genetic evidence. It differs much in appearance from the typical white-eyes, ''Zosterops'', but is approached by some Micronesian taxa; its color pattern is fairly unique save the imperfect white eye-ring.
In 2003, Alice Cibois published the results of her study of mtDNA cytochrome ''b'' and 12S/16S rRNA sequence data. According to her results, the white-eyes were likely to form a clade also containing the Yuhinas, which were until then placed with the Old World babblers, a large "wastebin" family. Previous molecular studies (e.g. Sibley & Ahlquist 1990, Barker ''et al.'' 2002) had together with the morphological evidence tentatively placed white-eyes as the Timaliidae's closest relatives already. But some questions remained, mainly because the white-eyes are all very similar birds in habitus and habits, while the Old World babblers are very diverse (because, as we now know, the group as formerly defined was polyphyletic).
Combined with the yuhinas (and possibly other Timaliidae), the limits of the white-eye clade to the "true" Old World babblers becomes indistinct. Therefore, the current (early 2007) opinion weighs towards merging the group into the Timaliidae, perhaps as a subfamily ("Zosteropinae"). Few white-eyes have been thoroughly studied with the new results in mind, however, and almost all of these are from ''Zosterops'' which even at this point appears over-lumped. Also, many "Old World babblers" remain of unresolved relationships. Whether there can be a clear delimitation of a white-eye subfamily or even a young or emerging family is a question that requires a more comprehensive study of both this group and Timaliidae to resolve.(Jønsson & Fjeldså 2006)
For example, a revision of the yuhinas and the genus ''Stachyris'' (Cibois ''et al.'' 2002), based on the same genes as Cibois (2003), revealed that the Philippine species placed in the latter genus by some were actually yuhinas. However, when the review by Jønsson & Fjeldså (2006) was published, no study had tried to propose a phylogeny for the newly-defined yuhinas including the white-eyes. Therefore, Jønsson & Fjeldså (2006) give a rather misleading phylogeny for the group. It appears as if the yuhinas are polyphyletic, with the White-collared Yuhina being closer to the ancestor of the ''Zosterops'' white-eyes than to other yuhinas including the species moved from ''Stachyris'' (Cibois ''et al.'' 2002).
