Pink-footed Shearwater

Identification

The pink-footed shearwater is a large seabird measuring 48 cm in length with a wingspan of 109 cm. It has distinctive sooty-brown upperparts contrasting with white underparts, and most notably, a pale pink bill with a dark tip and pink legs. The species is polymorphic, occurring in both darker- and lighter-phase populations. Its plumage is characteristically dull with little colour variation, which helps distinguish it from similar species such as the black-vented shearwater. Male pink-footed shearwaters are on average larger than females, though morphological features such as bill size, tail length, and body size can also vary between breeding colonies, likely reflecting adaptations to local environmental conditions and food availability.

Range & Habitat

The pink-footed shearwater is a pelagic species found throughout the Pacific Ocean. It predominantly nests on offshore islands off Chile, notably on Mocha Island, where it breeds in burrows on forested slopes as a colonial nester. After raising its young, the species undertakes a remarkable transequatorial migration, moving toward subarctic waters of the Pacific. During the warmer months of the year, it is fairly common well off the West Coast of the United States, making it accessible to observers in North American waters during this period.

Behaviour & Diet

Pink-footed shearwaters are colonial nesters that breed in burrows on forested slopes. They are not particularly vocal birds but may produce a distinctive horse-like whinny when feeding. The species is an impressive long-distance migrant, traveling vast distances between its Southern Hemisphere breeding grounds and subarctic feeding areas. Their diet consists mainly of fish, squid, and crustaceans, which they pursue while at sea. The species is closely related to the flesh-footed shearwater, with which it forms a superspecies group, though recent genetic studies have found very little difference between the two taxa.

Best Time & Places to See It

The best opportunity to observe pink-footed shearwaters for most nature travellers and photographers is along the West Coast of the United States during the warmer months, when the species is fairly common in offshore waters following its transequatorial migration from Chilean breeding grounds. Those visiting Chile itself may encounter the species near its breeding colonies on offshore islands such as Mocha Island, though access to these remote sites may be limited. The species' long-distance pelagic habits mean that dedicated seabird watching trips offshore offer the most reliable viewing opportunities.

Photography Tips

Photographing pink-footed shearwaters presents the typical challenges of seabird photography at sea. Their characteristic pale pink bill with dark tip and pink legs are diagnostic field marks worth capturing in clear detail to aid identification and distinguish them from similar shearwater species. The contrast between sooty-brown upperparts and white underparts provides good compositional potential when birds are visible in flight or resting on the water. Given that these are pelagic birds found well offshore, successful photography will require boat-based seabird watching trips, where stable positioning and patience are essential for obtaining quality images of these dynamic ocean dwellers.
