Hawaiian honeycreepers are a group of small, passerine birds endemic to Hawaiʻi. They are closely related to the rosefinches in the genus Carpodacus, but many species have evolved features unlike those present in any other finch.
Why is the Hawaiian honeycreeper important?
Honeycreepers are unique to Hawai’i and have a special place in the heart of Hawaiians and ecologists alike. In native Hawaiian culture, the birds are considered spiritual guides for families; their feathers are symbols of power. For ecologists, honeycreepers are an impressive example of adaptive radiation.
Why is the honeycreeper endangered?
The honeycreepers are threatened by recently introduced predation, competition, parasitism, degradation of habitat, and infectious disease including mosquito-borne avian malaria. One of the consequences of the invasive birds is the introduction of avian malaria.
What does a honeycreeper look like?

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

Where is the Hawaiian honeycreeper located?
Geographic range: Apapanes are found in ohia lehua rainforests (forests that contain ohia lehua trees) of Hawaii. They commonly range in forested areas over 3,300 feet (1,000 meters) in elevation on Hawaii, Oahu, and Kauai. They are vary rare or extinct on Lanai and Molokai.

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.
