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.
Procellariids are also vulnerable to general marine pollution, as well as oil spills. Some species, such as the Barau's petrel, the Newell's shearwater or the Cory's shearwater, which nest high up on large developed islands are victims of light pollution. [98] Chicks that are fledging are attracted to streetlights and are unable to reach the sea.
