Justification of Red List category
This species is listed as Critically Endangered because it is estimated to have an extremely small population that is inferred to be in decline owing to the interacting threats of human-driven habitat loss, habitat damage caused by cyclones, invasive species and non-target mortality caused by hunters. There is now an urgent need for intensive conservation actions to halt the species's perilous slide towards extinction.
