This species is listed as Critically Endangered owing to an ongoing range contraction caused by excessive predation by introduced mice. Mouse predation has forced this species out of coastal areas into sub-optimal upland habitat and is causing the population to decline. Urgent conservation intervention, which would also benefit the island's breeding seabirds, is needed to reverse this decline.
