形态与习性
The Christmas shearwater or ʻaoʻū (Puffinus nativitatis) is a medium-sized shearwater of the tropical Central Pacific. It is a poorly known species due to its remote nesting habits, and it has not been extensively studied at sea either. It is one member of a very ancient lineage of the small Puffinus species. Its only close living relative is the Galápagos shearwater (P. subalaris).
