Over 50 species of honeycreeper once lived in Hawai’i, but now only 17 species remain after battling against invasive species and habitat loss. Today, even those survivors are threatened further by avian malaria. To stop the disease, conservationists use innovative techniques to suppress the population of the invasive mosquitoes that spread it.

Millions of years ago, a single rosefinch species arrived on the Hawai’ian islands and evolved into over 50 species of honeycreepers — a phenomenon known as adaptive radiation.

Hawaiian honeycreepers are a group of songbirds endemic to the Hawaiian islands, all descended from a single species that arrived from the mainland six to seven million years ago. They are considered a dramatic example of adaptive radiation, a phenomenon in which a single species rapidly diversifies into many different ones. At one point, there were more than 50 different honeycreeper species on the islands, each sporting its own unique coloration, beak shape, and diets. 

When a single ancestor species rapidly evolves into many different, specialized species, this is known as adaptive radiation.

Hawai’i is home to a broad, beautiful array of birds species found only on its islands—like the stunningly diverse honeycreepers, many on the border of extinction. Now, a local team is removing invasive predators, restoring habitats, and battling mosquito-borne diseases to protect honeycreepers from their latest threat: avian malaria.

In addition to the impact of avian malaria, Hawai’i’s endangered honeycreepers are threatened by habitat loss and invasive predators — two problems that harm native bird populations everywhere, likely in your own back yard. Whether you’re looking to help Hawai’i’s birds, or if you’re hoping to make a difference to protect birds locally, the solutions […]
