An endangered Hawaiian duck, the Koloa Maoli, died on Kauai from avian influenza, confirmed by the National Veterinary Services Laboratories. The bird was found sick in the Hanalei Wildlife Refuge last November 2025 and died within a day despite treatment. The bird flu was likely spread by migratory waterfowl, which commonly carry the virus, as reported by KHON2.
The Hawaii Department of Health and the Department of Agriculture and Biosecurity are monitoring public health, poultry farms, and wild birds. They are investigating to understand and limit the spread of the virus, especially during migratory bird season. The public is advised not to handle wild waterfowl and shorebirds, which can carry avian diseases, according to KITV.
State officials are advising people to avoid sick or dead birds, especially waterfowl and shorebirds, to reduce the risk of infection. If handling is necessary, gloves and safety precautions should be used. The Department of Health and the Department of Agriculture and Biosafety have provided phone numbers and guidelines for reporting sick wildlife, livestock, or unusual animal illnesses.
