San Cristóbal I, in Galapagos.

The last sight record was in the 1980s: surveys in 1998 failed to find it#R#R. Habitat loss caused by alien invasive plants, resulting in a loss of food supply, appears to be a major reason for its demise, although mosquito-borne avian disease may have been a contributory factor#R.
