Honeycreeper populations have decreased as much as 98 percent over the past 15 years.

Why are honeycreepers only found on the Hawaiian Islands?

Higher elevations are also cooler, and therefore less conducive to mosquitoes and the diseases they carry. Native Hawaiian birds — particularly the honeycreepers — tend to be highly susceptible to avian malaria, which arrived on the islands only in recent history, long after the birds had evolved there.
