Justification of Red List category
This species's future hold on its mainland range is precarious, with a complex array of threats causing rapid declines resulting in local extinctions. Its situation may be unique in that the species remains numerous on a very large number of islands. Whilst population declines have slowed to an extent over the last ten years, the species is projected to undergo rapid population declines over the next decade based on extrapolation from historic trends, the absence of any change in the threatening processes, and the impact of climate change. It is therefore considered Vulnerable.
