Pink-footed shearwater description

KingdomAnimalia
PhylumChordata
ClassAves
OrderProcellariiformes
FamilyProcellariidae
GenusPuffinus (1)

Members of the shearwater genus cruise the oceans, gliding so low that they appear to shear the water surface. The wings are long and slender, usually used for gliding rather than flapping flight. The pink-footed shearwater is dully coloured, being mostly brown and white, but with pale pink feet and legs that give this species its name. The head and upperparts are brown, fading to white on the underside, with mottled sides and underwings. Both paler and darker individuals of the species have been seen (2).

Pink-footed shearwater biology

Arriving at the breeding colonies in November and December, the pink-footed shearwater lays one white egg in a burrow between December and January. Both parents share the incubation duties, foraging in between shifts (2). After 48 – 56 days the egg hatches (3), and the chick will rapidly learn to fly, before leaving the breeding site in April or May (2).

Feeding out to sea, the pink-footed shearwater dives, plunges and picks food from the surface. It takes sardines, anchovies, squid and occasionally crustaceans (2) (3).

Pink-footed shearwater range

Spending much of its time over the east Pacific Ocean, the pink-footed shearwater breeds on just three islands; Robinson Crusoe and Santa Clara in the Juan Fernández Islands, and Isla Mocha off the central Chilean coast. It spends the winter season off the western coast of North America, and has also been seen off the coast of Argentina, and around Australia and New Zealand (2).

Pink-footed shearwater habitat

A pelagic species, the pink-footed shearwater comes to land to breed, preferring to burrow into soil amongst scattered vegetation on the Juan Fernández Islands, but nesting on mountain ridges in a forest habitat (2).

Pink-footed shearwater status

The pink-footed shearwater is classified as Vulnerable (VU D2) on the IUCN Red List 2004 (1) and is listed on Appendix I of the Convention on Migratory Species (CMS or Bonn Convention) (4).

IUCN Red List species status – Vulnerable

Pink-footed shearwater threats

The biggest threat to this species is poor breeding success following loss of eggs and chicks to rats, cats, coatis, and dogs, as well as to local people. Goats and rabbits are responsible for over-grazing that leads to soil erosion and the loss of suitable nesting burrows. Like many seabirds, this species is also threatened by the fishing industry, as it becomes entangled in fishing gear across its range. Pollution may also be a threat (2).

Pink-footed shearwater conservation

In 1935 the Juan Fernández Islands were designated as a National Park, but were only protected from 1967. In 1977 they were upgraded to become a Biosphere Reserve, and they have now been nominated for inclusion in the list of World Heritage Sites. The breeding site on Isla Mocha is in a guarded national reserve which has had a management plan since 1998. The government of Chile has worked to improve the habitat of the shearwater since 1997. Collecting chicks is illegal, but enforcement is weak, and further efforts are necessary. The removal of introduced mammals has been proposed (2).

Glossary

Crustacea
Diverse group of arthropods (a phylum of animals with jointed limbs and a hard chitinous exoskeleton) characterised by the possession of two pairs of antennae, one pair of mandibles (parts of the mouthparts used for handling and processing food) and two pairs of maxillae (appendages used in eating, which are located behind the mandibles). Includes crabs, lobsters, shrimps, slaters, woodlice and barnacles.
Genus
A category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
Pelagic
Inhabiting the open oceans.
