Annobón white-eye

The Annobón white-eye, Zosterops griseovirescens, is a small songbird in the family Zosteropidae, the white-eyes. It is endemic to the island of Annobón, part of Equatorial Guinea in the Gulf of Guinea, and lives nowhere else. The bird reaches about 12 centimetres in length, with wings up to 6.2 centimetres and a tail up to 2.1 centimetres long. Its natural habitats are subtropical or tropical moist lowland forest and plantations. Its entire distribution area covers only about 17 square kilometres, which is why its conservation status mattered: the IUCN listed it as vulnerable until 2021, when it updated the status to least concern. The species was treated in Otto Finsch work on the Zosteropidae of 1901, and a survey of the birds of the island, then called Pagalu, was published in Malimbus in 1990 by M. J. S. Harrison. The Wikipedia article is short, so this entry records only what it supports and leaves diet, behaviour and breeding as open questions for deeper sources.
