Nesillas aldabrana (Aldabra brush warbler)

The Aldabra brush warbler (Nesillas aldabrana) is unique to the raised coral atoll of Aldabra, western Indian Ocean, where it was discovered in dense scrub habitat at the western end of Ile Malabar as recently as 1967.

Species detail

The auther studied a small population of about six individuals here over two years in the mid 1970s, but found no evidence of the species elsewhere on the atoll. The last living individual was seen in 1983, since when intensive searches have failed to re-discover the species and it is now presumed to be extinct.
