Abstract
Nearly 70 percent of Hawaii's native bird species are found nowhere else on Earth, and many of these species are declining or in danger of extinction. Although the Hawaiian Islands were once home to a remarkable diversity of waterfowl, only three species remain-the Hawaiian Goose (Nene), Laysan Duck, and Hawaiian Duck (Koloa maoli)-all Federally endangered. The Koloa maoli is the only Hawaiian bird threatened by 'genetic extinction' from hybridization with an invasive species-feral Mallard ducks. U.S. Geological Survey (USGS) biologists in Hawaii are working to find the causes of bird endangerment and ways to prevent extinction of the Koloa maoli and other threatened birds.
