The last individual in the wild of this species died in 1987 following catastrophic declines owing to predation by the introduced brown tree-snake. A captive population survives in a snake-proof enclosure, and it breeds well in captivity. It remains classified as Extinct in the Wild until an introduced population becomes firmly established.
