From The Independent in Britain:
Darwin finch could disappear from Galapagos islands
The Galapagos islands could be about to witness the first disappearance of a species in the 170 years since Charles Darwin’s historic visit, after scientists warned that the mangrove finch has been driven to the brink of extinction.
Despite occupying just one square kilometre of mangrove forest, their habitat is under threat from the arrival of humans. …
The finch is an elusive bird and Darwin himself never saw it during his survey.
Today it survives in just two patches of mangrove forest on the north-east coast of the largest island in the chain, Isobela.

July 2010: The first stage of attempts to translocate mangrove finch is underway. The critically endangered species – a member of Charles Darwin’s finch group of the tanager family – currently survives in two small patches of mangrove on the west of Galapagos island of Isabela., with a small remant population of about five birds in the South East of the island: here.
