Small island species, confined to limited terrain, are always vulnerable, particularly to invasive species, burgeoning human populations, and new diseases. On Hawaii, climate change intersects with these three factors to imperil its unique birds, including six species of honeycreeper.
The small, often brightly coloured honeycreepers tend to survive at higher altitudes where their forest habitat is less likely to be destroyed by humans. Higher elevations are also cooler, and less attractive to mosquitoes, which were first carried to Hawaii in the 19th century, long after the birds had evolved there. Outbreaks of mosquito-borne diseases such as avian malaria and avian pox began soon afterwards.
