Generally considered extinct.
The species was only discovered in 1967, but the last individual from the tiny population studied in the 1970s was seen in 1983. Since then, detailed searches, notably in 1986 and 2003-4, have failed to rediscover the species.
Various potential causes for its disappearance have been discussed, but it seems most likely to have been due to introduced black rats Rattus rattus, which heavily depredate the nests of most Aldabra songbirds.
Two specimens and one nest with three eggs exist in the collections of the Natural History Museum, U.K.
