The 'ua'u, or Hawaiian petrel (Pterodroma sandwichensis), is a federally endangered native seabird. The habitat suitability model (which does not incorporate spatial information on anthropogenic threats to the species) predicts approximately 74 km2 of Kauai, mostly in the interior of the island, as being potentially suitable with predicted probability > 0.7 for Hawaiian petrel terrestrial activity, and about 35 km2 with predicted probability > 0.9. The Hawaiian petrel is a large, nocturnal petrel endemic to Hawaii, where it nests on the islands of Maui, Hawaii, Lanai, and Kauai, and possibly on Molokai, the sea stacks off of Kahoolawe, and Lehua Islet.
