- Pterodroma macroptera
Identification
Length 40-41cm. Wingspan 97cm
Large, dark and long-winged gadfly-petrel that can resemble the darker shearwaters.
Adult: almost entirely blackish-brown with an indistinct greyish patch around the bill-base and underwing with silvery flash across coverts. Iris brown, bill all black, short and stout, legs black.
Juvenile: as adult but with more distinct grey face patch.
Distribution
Widespread in the Southern Oceans.
Breeds on Tristan da Cunha and Gough Island, on Crozet, Marion, Prince Edward and Keruelen Islands, perhaps also Amsterdam Island. Also breeds on islands off the south coast of Western Australia between Eclipse Island near Albany to Cape Arid and particularly on the Recherche Archipelago.
In New Zealand breeds on many offshore islands and at a few sites in the north of the mainland of North Island. Adults are sedentary but juveniles disperse widely and occur mainly between 30°S and 50°S in the southern Atlantic and Indian Oceans and the south Pacific east to about Pitcairn Island. Fairly common off southern African coasts reaching 10°S off the west and 19°S off the east. Common off the south coast of Western Australia, also occurring off Victoria, presumably from New Zealand breeding range.
Has been recorded near Cape Horn.
Taxonomy
Subspecies
- P. m. macroptera:
- Breeds and ranges islands and seas in southern oceans, from Tristan da Cunha to Australia
- P. m. gouldi: (Grey-faced): grey face patch extending to sides of face and chin and thus very similar to juvenile nominate
- Breeds on islands off North Island (New Zealand) and south-western Australia
Habitat
Breeds on islands or remote headlands, otherwise at sea. Shy at sea and rarely follows ships.
Behaviour
Flight
Swift and powerful, hurried with high sweeping arcs. Distinguished from darker shearwaters by bull-necked and head-down appearance and also short, thick bill. Also resembles Kerguelen Petrel P. brevirostris but larger and browner.
Diet
Squid and crustaceans with some fish.
Breeding
Breeds February to November in a burrow or under a rock or vegetation, singly or in loose colonies. Eggs: 1, white (66 x 47mm) laid in May, hatch in mid-July-August and young fledge by November.
