The pink-footed shearwater (Ardenna creatopus) is a species of seabird. The bird is 48 cm (19 in) in length, with a 109 cm (43 in) wingspan. It is polymorphic, having both darker- and lighter-phase populations. Together with the equally light-billed flesh-footed shearwater, it forms the Hemipuffinus group, a superspecies that may or may not have an Atlantic relative in the great shearwater.[2][3] These are large shearwaters which are among those that could be separated in the genus Ardenna.[4]

This species is pelagic, occurring in the Pacific Ocean. It predominantly nests on offshore islands off Chile, i.e. Mocha Island. It is a transequatorial migrant, moving toward subarctic waters of the Pacific after raising its young. It is fairly common well off the West Coast of the United States during the country's warmer months.

The pink-footed shearwater feeds on mainly fish, squid, and crustaceans.

This bird nests in burrows, preferring forested slopes. It is a colonial nester.

Numbers of this shearwater have been reduced due to predation by introduced species, such as rats and cats. Some loss of birds also occurs from becoming entangled in fishing gear. The pink-footed shearwater is one of the species to which the Agreement on the Conservation of Albatrosses and Petrels applies.[5]
