Justification of Red List category
This species has undergone rapid declines in the past, mainly through predation by introduced cats. While other threats continue to locally cause the loss and degradation of habitat within the small breeding range, the population has been showing signs of recovery since the eradication of cats from the principal breeding island. For these reasons, the species is listed as Near Threatened.
