Justification of Red List category
This species is classified as Vulnerable on the basis of a small estimated population which is suspected to be declining. It is judged to have distinct subpopulations, some totalling more than 250 birds. If subpopulations are found to be smaller or, conversely, that movement of birds between them means that all birds are in a single population, the species would warrant uplisting to Endangered.

Population size: 250-999

Population trend: Decreasing
