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.
ʻAʻo (Newell's shearwater, Puffinus newelli) is a medium-sized shearwater measuring 12–14 in (30–36 cm) with a wing span of 30–35 in (76–89 cm). It has a glossy black back and white belly and a black bill that is sharply hooked at the tip.
Many shearwaters are long-distance migrants, perhaps most spectacularly sooty shearwaters, which cover distances in excess of 14,000 km (8,700 mi) from their breeding colonies on the Falkland Islands (52°S 60°W) to as far as 70° north latitude in the North Atlantic Ocean off northern Norway, and around New Zealand to as far as 60° north latitude in the North Pacific Ocean off Alaska.

The wings of all species are long and stiff. In some species of shearwater the wings are used to power the birds underwater while diving for prey. Their heavier wing loadings, in comparison with surface-feeding procellariids, allow these shearwaters to achieve considerable depths (below 70 m (230 ft) in the case of the short-tailed shearwater ...
Puffinus is a genus of seabirds in the order Procellariiformes that contains about 20 small to medium-sized shearwaters.Two other shearwater genera are named: Calonectris, which comprises three or four large shearwaters, and Ardenna with another seven species (formerly often included within Puffinus).

The Manx shearwater (Puffinus puffinus) is a medium-sized shearwater in the seabird family Procellariidae.
