Justification of Red List category
This species has experienced rapid declines in some parts of its range, and is projected to decline substantially by 2100 as a result of climate change and the resultant increased prevalance of avian malaria. The newly-introduced tree disease known as Rapid 'Öhi'a Death may also cause declines. Overall, a population reduction of 30-49% is suspected to occur over the next ten years and so the species is listed as Vulnerable.
