Justification of Red List category
This species was previously classified as Near Threatened as, although it has a single, small population, it was not thought to be declining. It is now
thought to be experiencing a continuing decline owing to declines in habitat quality, and probable decreases in survival and breeding success, as caused by human activities and other
problematic species, and it has therefore been uplisted to Vulnerable.
