The Aldabrabuschsänger ( Nesillas aldabrana, mistakenly Nesillas aldabranus ), sometimes referred to as Aldabra brush warbler, a presumably extinct Singvogelart from the family of reed warbler -like is ( Acrocephalidae ).

The Aldabrabuschsänger reached a length of 13 cm and a wing length of 6.3 cm. The tail length was 8.6 cm and weight 19.5 grams. The skull and the top were lively brown. Rump and upper tail-coverts were more cinnamon. The sides of the head were gray brown. The gray- white eye-streak was over clearly marked. The wings were dark brown with light tan feather edges. The long graduated tail consisted of twelve feathers. He was tan - brown in color. The bottom was gray-white.

Discovery and extinction

The Aldabrabuschsänger was not discovered until the end of 1967 on the Aldabraatoll ( a part of the Seychelles) in the Indian Ocean. The British ornithologist Robert Prys - Jones of the Natural History Museum in London was a male, a female and a nest with three eggs. Young birds has never been proven, however.

Until the mid- 1970s, further searches were unsuccessful after the bird, as it Prys -Jones succeeded in the end of 1975, six additional copies, all of them to find, to ring and photograph males.

The species was endemic in a 10-hectare coastal strip at the western end of the island Malabar. A single male was seen in 1983. In 1985 he was described in the literature as the rarest and in its most restricted distribution of birds in the world. Despite an intensive search had in 1986, the extinction to be confirmed, and since 1994 the bird is officially on the list of extinct bird species in the IUCN. Rats, cats and imported goat had apparently contributed to the extinction of the species.
