The soft-plumaged petrel (Pterodroma mollis) is a species of seabird in the family Procellariidae.

Contents

Distribution

It breeds on islands in the Southern Hemisphere, nesting on Tristan da Cunha, Gough Island, the Prince Edward Islands, Crozet Islands, Macquarie Island, and on the Antipodes Islands of New Zealand. Small numbers breed in the Maatsuyker Island Group of southern Tasmania. It disperses outside the breeding season, reaching eastern South America north to Brazil, southern Africa and Australia. It has occurred as a vagrant in Israel, Norway and Jordan.

Taxonomy

Fea's petrel (P. feae), Desertas petrel (P. desertae) and Zino's petrel (P. madeira) of the North Atlantic were formerly treated as subspecies of this bird.

Description

The soft-plumaged petrel is a medium-sized petrel. Its plumage is dark grey and white, and its wings are narrow and with a pointed tail distinct in flight. It has a dark grey head with prominent white feathers on the cheeks and throat. There is a white speckling on forehead along with a prominent dark eye patch. Its underside is mostly white, which turned dark grey at underwings. The bill is black and about 25–32 mm long and has a sharp hook. Its legs are pink with black on the outer webs and toes. There is also the dark morph, which is another variation of the petrel. [2]

Both sexes are noisy, making medium-pitched moans and shrill squeaks.

<span class="mw-page-title-main">Fea's petrel</span> Species of bird

The Fea's petrel is a small seabird in the gadfly petrel genus, Pterodroma. It was previously considered to be a subspecies of the soft-plumaged petrel, but they are actually not closely related at all. However, P. feae is very closely related to Zino's petrel and Desertas petrel, two other species recently split from P. mollis. The gadfly petrels are named for their speedy weaving flight, as if evading horseflies. The flight action is also reflected in the genus name Pterodroma, from Ancient Greek pteron, "wing" and dromos, " runner". This species is named after the Italian zoologist Leonardo Fea (1852-1903).

<span class="mw-page-title-main">Zino's petrel</span> Small seabird in the gadfly petrel genus

Zino's petrel or the freira, is a species of small seabird in the gadfly petrel genus, endemic to the island of Madeira. This long-winged petrel has a grey back and wings, with a dark "W" marking across the wings, and a grey upper tail. The undersides of the wings are blackish apart from a triangle of white at the front edge near the body, and the belly is white with grey flanks. It is very similar in appearance to the slightly larger Fea's petrel, and separating these two Macaronesian species at sea is very challenging. It was formerly considered to be a subspecies of the soft-plumaged petrel, P. mollis, but they are not closely related, and Zino's was raised to the status of a species because of differences in morphology, calls, breeding behaviour and mitochondrial DNA. It is one of Europe's most endangered seabirds, with breeding areas restricted to a few ledges high in the central mountains of Madeira.

<span class="mw-page-title-main">White-necked petrel</span> Species of bird

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. 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.
