About Laysan Duck
Kauaʻi fossil material has been compared provisionally with Anas laysanensis. The comparison does not establish that the fossil belongs to the living species.
Kauaʻi evidence
A Hawaiʻi-level record is available, but the species needs a documented Kauaʻi observation before local ecological conclusions are drawn. Makauwahi reports Anas cf. laysanensis; cf. marks a provisional resemblance. The currently accepted species name is retained for the broader species account, but Kauaʻi fossil identity is not certain.
