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.

Food and resource needs

For Kauaʻi, Red-necked Grebe 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.
