First on the list is Hawaii's Akikiki or Kaua'i creeper, a type of native honeycreeper. Nearly all of Hawaii's endemic birds have been decimated by introduced species. But it's the mosquito — accidentally introduced to the islands in the early 1800s by European colonizers — that has most damaged the Akikiki by spreading avian malaria. The last safe haven for the birds lies in the high-altitude, cool mountains of Kauaʻi — a place too cool for mosquitoes to thrive. Global warming is on track to take away this safe place.
