Description
Description
The pink-footed shearwater (Ardenna creatopus) is a species of seabird. The bird is 48 cm in length, with a 109-cm 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. These are large shearwaters which are among those that could be separated in the genus Ardenna. 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.
Size
41 - 81 cm
Feeding Habits
Pink-footed Shearwater primarily consume fish, squid, and crustaceans, foraging by diving into the ocean, often coordinating with other seabirds. They exhibit unique preferences for certain prey during breeding season, adapting their diet as needed.
Habitat
Pink-footed Shearwater predominantly inhabits marine environments, thriving in the nutrient-rich zones of the eastern Pacific, particularly within the pelagic realm over continental shelves where the Humboldt and California Current Systems prevail. For breeding, pink-footed Shearwater selects island locales off the central coast of Chile, where it nests colonially. The nesting sites vary, ranging from open areas to forested terrains, often situated on rugged slopes.
Nest Behavior
Pink-footed Shearwater's nesting season begins in late Southern Hemisphere spring, with eggs generally laid in early December, and involves nocturnal activity, duets, and mutual preening between mates.
Nest Characteristics
Pink-footed Shearwater nests in long underground burrows with sparse linings, commonly found on secluded islands off the coast of Chile.
