About Harlequin Duck
Harlequin Duck (Histrionicus histrionicus) appears in the wider Hawaiian bird catalog, but the Bishop Museum's 2017 island checklist has no Kauaʻi occurrence code for it. An island-specific record is needed before claiming local presence.
Kauaʻi evidence
A Hawaiʻi-level record is available, but the species needs a documented Kauaʻi observation before local ecological conclusions are drawn.

Habitat and ecology
- Habitats
- Wetlands · Taro fields · Ponds · Estuaries · Coastal habitat
- Food and resource needs
- For Kauaʻi, Harlequin Duck has no standing local food dependency until an occurrence is validated. If recorded, attach the observation to transient access to aquatic vegetation, seeds, algae, submerged plant material, aquatic invertebrates, mollusks, crustaceans, small fish, or planktonic prey according to foraging type.
- Reproduction
- Breeding on Kauaʻi is not established; seasonal resting and foraging habitat may be relevant.

- Shelter and structure within wetlands, taro fields, ponds.
Threats and conservation
- Threats
- Wetland condition, avian disease, survey detectability, and rare-record review are the relevant open questions
- Conservation actions
- Document date, place, observer, habitat, and supporting media · Confirm identification and Kauaʻi occurrence before local conservation use
- Monitoring
- Document date, place, observer, habitat, behavior, and supporting media for any Kauaʻi observation.
