The Hawaiian Petrel, or 'Ua'u, is an endangered gadfly petrel endemic to the Hawaiian Islands. It is a nocturnal breeder in remote mountain areas.
Where to spot
Breeds on the high-altitude slopes of Maui, Kauai, and Hawaii (Big Island). Forages widely in the central and eastern Pacific Ocean, reaching as far as Alaska and the Aleutians.
How to spot
Look for its dark grey-brown upperparts, white underparts, and dark underwing. Its flight is powerful and arcing. Best observed from boats during pelagic tours around the Hawaiian Islands, or very rarely from land at night near breeding sites.
When to spot
Breeding occurs from March to October. Can be observed at sea during these months around Hawaii. Nocturnal at colonies.

The 'Ua'u is named for its distinctive, eerie nocturnal call, which sounds like 'oo-AH-oo', echoing across the Hawaiian volcanic slopes where it nests.
