Japanese White-eye, Zosterops japonicus
Native to east Asia, these little birds were introduced to Hawaii in 1929 to aid in insect control, and have since become the most
common landbirds in the islands. I photographed this one in Haena, Kauai, an island on which they are especially abundant,
with a population estimated at more than 250,000. They clearly belong in the ornithological category technically known as
"really, really cute," but they threaten the fragile native forest species of the islands by diseases they brought from the Asian
mainland and by competition for food.
