About Hooded Merganser

Hooded Merganser (Lophodytes cucullatus) is recorded as a vagrant on Kauaʻi in the Bishop Museum's 2017 island checklist. This is a documented island occurrence, not a claim of an individual sighting in 2026.

Kauaʻi evidence

Bishop Museum island checklist (version 2, 2017) lists Kauaʻi status V: vagrant. See original island table. A Hawaiʻi-level record is available, but the species needs a documented Kauaʻi observation before local ecological conclusions are drawn.
