The Seychelles white-eye (''Zosterops modestus'') is a rare warbler-like perching bird from the family of white-eyes (Zosteropidae). It is endemic to the Seychelles. ==Description== This ten to eleven centimetre long bird has a plumage with olive grey upperparts and dull coloured underparts. It is further characterized by a white narrow eye-ring, a rather long dark grey tail and a small sharp bill. Its diet consists of insect larvaes, locusts, and grasshoppers as well as berries and seeds. The breeding season is from September to April and a clutch of two to seven eggs is laid into a cup-shaped nest. The incubation time is thirteen to fifteen days and the young are fully fledged after eleven to sixteen days. After that the parents are looking after them another two months. Its melodious and complex song consists of nasal tones. Due to its ecology and foraging in the canopy of high trees it is difficult to observe. The existence of an amazingly complex cooperative breeding system was discovered among Seychelles white-eyes. It is apparently unique among all species of white-eyes and appears as a very peculiar social breeding organisation among birds in general. Within the same breeding territory, the individual composition of nesting groups constantly changes, often involving birds that sometimes also contribute to nests in other territories.
