Third possible case of Highly Pathogenic Avian Influenza detected in Hawaiʻi

Hawaiʻi’s first detection of H5N1 occurred in November 2024 in a backyard flock on Oʻahu, followed by a hybrid duck found on Oʻahu’s North Shore. This year, two additional cases have been confirmed in migratory Koloa Māpu ducks—one on Oʻahu and one on Maui. This Kauaʻi detection is the first potential case in a native bird, likely introduced through infected migratory waterfowl.
