Branta sp. ‘Kaua’i’

Medium Kauai Nene (Branta sp.)
The Medium Kauai Nene is known only from the subfossil remains of one individual that were recovered from the deposits of the Makawehi Dunes on the island of Kaua’i, Hawaiian Islands.

This form was more robust than the likewise extinct form known from O’ahu. [1]
