Murphy's petrel (Pterodroma ultima) is a species of seabird and a member of the gadfly petrels. The bird is 38–41 cm length, with a 97 cm wingspan, and weighs about 360 g. [2] [3] Its plumage is all dark sooty-grey, except for a pale chin, and pinkish legs; [2] it does not exhibit sexual dimorphism. [4] It was described by Robert Cushman Murphy in 1949, which is the source of the species' common name.
Murphy's petrels take unusually long feeding trips during incubation. [4]
Very little is known about this species of petrel. It occurs in the South Pacific, nesting on rocky islets and cliffs off tropical oceanic islands in the Austral, Tuamotu, and Pitcairn groups. [1] It was not until the 1980s that it was determined that these petrels might be regular visitors far offshore of the west coast of North America. [5] It has been recorded off the coast of the Hawaiian Islands and well off the Pacific Coast of the United States and in the southern Gulf of Alaska. [6] Most reports of Murphy's petrels are over 64 km offshore [5] and the species reportedly has one of the greatest foraging ranges of any breeding seabird [7]
Procellariiformes is an order of seabirds that comprises four families: the albatrosses, the petrels and shearwaters, and two families of storm petrels. Formerly called Tubinares and still called tubenoses in English, procellariiforms are often referred to collectively as the petrels, a term that has been applied to all members of the order, or more commonly all the families except the albatrosses. They are almost exclusively pelagic, and have a cosmopolitan distribution across the world's oceans, with the highest diversity being around New Zealand.
The gadfly petrels or Pterodroma are a genus of about 35 species of petrels, part of the seabird order Procellariiformes. The gadfly petrels are named for their speedy weaving flight, as if evading gadflies (horseflies). The flight action is also reflected in the name Pterodroma, from Ancient Greek pteron, "wing" and dromos, "runner".
The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters. This family is part of the bird order Procellariiformes, which also includes the albatrosses and the storm petrels.
The black-capped petrel, also known as the diablotín, is a small seabird native to the West Indies in the genus Pterodroma. It is a long-winged petrel with a grey-brown back and wings, with a white nape and rump. Underparts are mainly white apart from a black cap and some dark underwing markings. It picks food items such as squid from the ocean surface.
The white-faced storm petrel, also known as white-faced petrel or frigate petrel is a small seabird of the austral storm petrel family Hydrobatidae (Oceanitidae). It is the only member of the monotypic genus Pelagodroma. It is widely distributed across the southern hemisphere, especially around the coastal and open ocean waters of southern Australia and New Zealand
The providence petrel is a large and heavy build gadfly petrel that nests in two locations in the Tasman Sea: Lord Howe Island and Philip Island.
The Galápagos petrel is one of the six endemic seabirds of the Galápagos. Its scientific name derives from Ancient Greek: Pterodroma originates from pteron and dromos, meaning "wing" and "runner", and phaeopygia comes from phaios and pugios, meaning "dusky" and "rump". Members of Pterodroma genus are also called the gadfly petrels because their erratic twisting and turning in flight resemble that of gadflies.
The Trindade petrel, also known as the Round island petrel, is a species of seabird and a member of the gadfly petrels. The bird is 35–39 cm (14–15 in) in size, with an 88–102 cm (35–40 in) wingspan.
The mottled petrel or kōrure is a species of seabird and a member of the gadfly petrels. It usually attains 33 to 35 cm (13–14 in) in length with a 74 to 82 cm (29–32 in) wingspan.
Cook's petrel, or the tītī or blue-footed petrel, is a Procellariform seabird. It is a member of the gadfly petrels and part of the subgenus Cookilaria Bonaparte, 1856, which includes the very similar Stejneger's petrel.
Stejneger's petrel is a species of seabird and a member of the gadfly petrels. The bird is 26–31 cm in size, with a 53–66 cm wingspan.
Buller's shearwater is a Pacific species of seabird in the family Procellariidae; it is also known as the grey-backed shearwater or New Zealand shearwater. A member of the black-billed wedge-tailed Thyellodroma group, among the larger shearwaters of the genus Ardenna, it forms a superspecies with the wedge-tailed shearwater.
The black storm petrel is a small seabird of the storm petrel family Hydrobatidae. It is 23 cm in length, with a wingspan of 46–51 cm.
The least storm petrel is a small seabird of the storm petrel family Hydrobatidae. It is 13–15 cm in length, with a wingspan of 32 cm. It is the smallest member of the order Procellariiformes. It was formerly defined in the genus Oceanodroma before that genus was synonymized with Hydrobates.
The Bonin petrel or nunulu is a seabird in the family Procellariidae. It is a small gadfly petrel that is found in the northwest Pacific Ocean. Its secretive habits, remote breeding colonies and limited range have resulted in few studies and many aspects of the species' biology are poorly known.
The white-necked petrel, also known as the white-naped petrel, is a species of seabird in the family Procellariidae. During the non-breeding season it occurs throughout a large part of the Pacific, but it is only known to breed on Macauley Island in New Zealand's Kermadec Islands and the Australian territory of Norfolk Island and Phillip Island. It formerly bred on Raoul Island, but has now been extirpated from this locality due to predation by rats and cats. Reports of breeding on Merelava, Vanuatu, are more likely to be the very similar Vanuatu petrel, P. occulta, which some consider to be a subspecies of the white-necked petrel. The IUCN rating as vulnerable is for the "combined" species.
The Juan Fernández petrel is a species of seabird in the family Procellariidae. It nests on a single island off the coast of Chile, in the Juan Fernández Archipelago. It was previously classified as a subspecies of the white-necked petrel, which is found in tropical waters of the Pacific and Indian Oceans.
Pycroft's petrel is a species of seabird in the petrel and shearwater family Procellariidae.
The Herald petrel is a species of seabird and a member of the gadfly petrels. Its range includes the south Pacific Ocean and Indian Ocean.
