Oceanodroma matsudairae

Oceanodroma matsudairae, Matsudaira’s Storm Petrel, Petrelbadai Matsudairae


Matsudaira’s Storm Petrel (Oceanodroma matsudairae) is a species of seabird in the Hydrobatidae family.

It breeds solely in the Volcano Islands in the north-west Pacific Ocean, and winters in the Indian Ocean. Its status is insufficiently known.

Oceanodroma monorhis

Swinhoe’s Storm Petrel (Oceanodroma monorhis), also known as Swinhoe’s Petrel, is a small, all-brown seabird of the storm petrel family Hydrobatidae.

It breeds on islands in the northwest Pacific off China, Japan and Korea. It nests in colonies close to the sea in rock crevices and lays a single white egg. It spends the rest of the year at sea, ranging into the Indian Ocean and Arabian Sea.

Pelagodroma marina

Pelagodroma marina, White-faced Storm Petrel, Petrelbadai Muka-putih


The White-faced Storm Petrel breeds on remote islands in the south Atlantic, such as Tristan da Cunha and also Australia and New Zealand. There are north Atlantic colonies on the Cape Verde Islands, Canary Islands and Savage Islands. It nests in colonies close to the sea in rock crevices and lays a single white egg. It spends the rest of the year at sea.

The White-faced Storm Petrel is 19–21 cm in length with a 41–44 cm wingspan. It has a pale brown to grey back, rump and wings with black flight feathers. It is white below, unlike other north Atlantic petrels, and has a white face with a black eye mask like a phalarope. Its plumage makes it one of the easier petrels to identify at sea.

The White-faced Storm Petrel is strictly pelagic outside the breeding season, and this, together with its often-remote breeding sites, makes this petrel a difficult bird to see from land. Only in severe storms might this species be pushed into headlands. There have been a handful of western Europe records from France, the United Kingdom and the Netherlands.

This storm petrel is strictly nocturnal at the breeding sites to avoid predation by gulls and skuas, and will even avoid coming to land on clear moonlit nights. Like most petrels, its walking ability is limited to a short shuffle to the burrow.

It has a direct gliding flight and will patter on the water surface as it picks planktonic food items from the ocean surface. It is highly gregarious, but does not follow ships.

Widespread throughout its large range, the White-faced Storm Petrel is evaluated as Least Concern on the IUCN Red List of Threatened Species.

Pterodroma baraui

Barau’s Petrel, Pterodroma baraui is a medium sized gadfly petrel from the family Procellariidae. Its main breeding site is the island of Réunion in the Indian Ocean.


Oceanites-oceanicus, Wilson’s Storm Petrel, Petrel badai Coklat


Wilson’s Storm Petrel (Oceanites oceanicus), also known as Wilson’s Petrel, is a small seabird of the storm petrel family. It is one of the most abundant bird species in the world and has a circumpolar distribution mainly in the seas of the southern hemisphere but extending northwards during the summer of the northern hemisphere. The world population has been estimated to be more than 50 million pairs.[2] The name commemorates the Scottish-American ornithologist Alexander Wilson.

The Flesh-footed Shearwater, Puffinus carneipes, is a small shearwater. Its plumage is black. It has pale pinkish feet, and a pale bill with a black tip. Together with the equally light-billed Pink-footed Shearwater, it forms the Hemipuffinus group, a superspecies which may or may not have an Atlantic relative in the Great Shearwater (Austin, 1996; Austin et al., 2004). These are large shearwaters which are among those that could be separated in the genus Ardenna (Penhallurick & Wink, 2004).

It breeds in colonies, and has two main breeding areas: one in the South West Pacific Ocean includes Lord Howe Island (20,000 to 40,000 pairs) and northern New Zealand (50,000 to 100,000 pairs); the other is along the coast of Western Australia from Cape Leeuwin to the Recherche Archipelago. Another 600 pairs breed on St Paul Island in the Indian Ocean, as well in the Astola Island of Pakistan in the Arabian Sea. It occurs as a summer visitor in the North Pacific Ocean as far north as British Columbia. Flesh-footed shearwaters have been sighted in the Central-North Pacific, above the main Hawaiian Islands as well.

Calonectris leucomelas

Calonectris leucomelas, Streaked Shearwater, Pengguntinglaut Belang


The Streaked Shearwater, Calonectris leucomelas is a species of seabird. The bird is 48 cm (19 in) in size, with a 122 cm (48 in) wingspan.

This species is pelagic, but also occurs in inshore waters. It occurs in the Pacific Ocean, nesting in Japan and many of its offshore islands. After breeding, the Streaked Shearwater migrates toward southern Australia. It has been reported well off the west coast of the United States and from the Southern coast of India.[1]

The Streaked Shearwater feeds mainly on fish and squid. It follows fishing boats, attracted to anchovy crawls off Japan.

Streaked Shearwater uses burrows to nest in. It prefers forested hills.

This bird is abundant and widespread, however some mortality occurs through becoming entangled in fishing nets, and from some predation by cats and rats. In addition, it is harvested by some traditional endemic human cultures.

Bulweria fallax

Bulweria fallax, Jouanin’s Petrel, Petrel Hindia


The gadfly petrels are seabirds in the bird order Procellariiformes. These medium to large petrels feed on food items picked from the ocean surface.

The short, sturdy bills of the Pterodroma species in this group, about 35 altogether, are adapted for soft prey taken at the surface; they have twisted intestines for digesting marine animals which have unusual biochemistries.

Their complex wing and face marking are probably for interspecific recognition.

These birds nest in colonies on islands and are pelagic when not breeding. One white egg is laid usually in a burrow or on open ground. They are nocturnal at the breeding colonies.

Pachyptila desolata

Pachyptila desolata, Antarctic Prion, Petrel Antartika


The Antarctic Prion is a member of the Pachyptila genus, and along with the Blue Petrel makes up the Prions. They in turn are members of the Procellariidae family, and the Procellariiformes order. The prions are small and typically eat just zooplankton;[2] however as a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the Prion are on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights.[3] Finally, they also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose
