Newell's shearwater or Hawaiian shearwater (ʻaʻo), (Puffinus newelli) is a seabird in the family Procellariidae. It belongs to a confusing group of shearwaters which are difficult to identify and whose classification is controversial. It was formerly treated as a subspecies of the Manx shearwater (Puffinus puffinus) and is now often placed in Townsend's shearwater (Puffinus auricularis). This shearwater is the only seabird endemic to the Hawaiian Islands. Its Hawaiian name "ʻaʻo" comes from the sound of its call. Native Hawaiians regarded the ʻaʻo's haunting song as an omen of death.
