Shearwater bird

The common, or Manx, shearwater (P. puffinus), whose length is 30 to 37 cm (about 12 to 15 inches), is a large species that breeds on several islands on both sides of the North Atlantic.

Why are they called shearwaters?

The name “Shearwater” comes from the birds' flight style of shearing across the fronts of waves with their wings held stiff. A study on Sooty Shearwaters found that they migrate in the range of 64,000 km in a single year, which gives them the longest migration ever recorded electronically of any animal on Earth.

Is a shearwater a mutton bird?

Shearwaters earned their name by their ability to cut - or shear - the water with their wings, although until recently they were known as 'muttonbirds'. This name was given to them by early European settlers, who killed the birds for food and found that their flesh tasted like mutton.

Where do shearwater birds migrate?

Short-tailed Shearwaters migrate north in April each year to the Arctic region, where they spend the northern hemisphere summer. They travel in flocks, and return to southern Australia to breed on islands and promontories off the Australian coast.

Can a shearwater fly?

One of the most widespread and numerous of all pelagic seabirds, the Sooty Shearwater is an unassuming, dark brown bird with silvery flashes in the underwing. With stiff wingbeats they fly low over the ocean ("shearing" the water), using wind power to glide long distances.

Is a shearwater a puffin?

The Manx shearwater (Puffinus puffinus) is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century.

What does a shearwater eat?

They feed on fish, squid, and similar oceanic food. Some will follow fishing boats to take scraps, commonly the sooty shearwater; these species also commonly follow whales to feed on fish disturbed by them. Their primary feeding technique is diving, with some species diving to depths of 70 m (230 ft).

What is the difference between a petrel and a shearwater?

Petrels in the UK are small, oceanic birds, which fly low over the sea, except for the larger fulmar. Shearwaters are larger, long-winged, flying over vast areas of sea by using winds and air currents over the waves.

Is a shearwater a petrel?

Shearwaters are members of the Petrel family and have long, pointed wings that they use to “shear” gracefully over the surface of the water while looking for schools of fish, plankton, or marine invertebrates upon which they feed.

Do dolphins and shearwater birds work together?

The seabird–dolphin associations were mainly observed during dusky dolphin surface feeding. Shearwaters and kelp gulls were mainly observed in flocks that were associated with dolphins, while Magellanic penguins and cormorants were mainly observed without dolphins.

What are mutton birds called?

The Muttonbird or Short-tailed Shearwater, Puffinus tenuirostris, only breeds in Australia and is probably Australia's most abundant seabird. It is a circum-Pacific migrant ranging to the Antarctic Circle in the breeding season and to the far North Pacific Ocean in the non-breeding season.

What is another name for mutton birds?

Muttonbird, Atrina zelandica Also known as the sooty shearwater or titi, the New Zealand muttonbird is Puffinus griseus and belongs to the order of sea birds known as petrels. As a name, “muttonbird” appears to have originated among early European settlers in Australasia and is said to refer to the taste of the flesh.

Why are shearwaters endangered?

Serious population declines are attributed to degraded island habitat, depredation by introduced land predators, light pollution, and collisions with power lines. It is estimated that the Newell's shearwater's population has been declining at rates far exceeding 50 percent over the species' last three generations.

Do shearwaters mate for life?

Shearwaters mate for life, and return to the same burrow each year to lay eggs and raise their chicks. They go on a long migration journey (sometimes over 30,000 km) not touching land until they arrive home to breed. When they need to rest, they form floating rafts of birds at sea.

How fast do shearwaters fly?

They have a short tail with blackish brown feathers and are often seen skimming along the ocean's surface at high speeds. With their long wing span and narrow wings, they can fly as fast as 85 km an hour!

Can shearwaters swim?

Newell's shearwaters feed mainly by plunging into the water in order to swallow prey. They can swim underwater, probably down to 10 meters below the surface.

Which sea bird can not fly?

Penguin. No list of flightless birds would be complete without the penguin. All 18 species of penguin are unable to fly, and are in fact better built for swimming and diving, which they spend the majority of their time doing.

Do shearwaters migrate?

'Austral' or southern breeders, Great Shearwaters (Ardenna gravis) migrate from breeding islands far to the south in the Atlantic before traveling to the Northern Atlantic to feed. This trip is 6,000 miles each way and, if they're lucky, Great Shearwaters will complete this round trip every year for a 60-year lifetime.

What are the 4 types of puffins?

Puffins are a group of marine birds distinguished by black, dark grey, or black and white, plumage and a vibrantly colored beak. The four puffins are the Tufted Puffin, the Horned Puffin, the Atlantic Puffin, and the Rhinoceros Auklet. They are members of the Alcidae family, more commonly known as the auks.

Can you touch a puffin?

They are friendly and curious animals, but they are still wild animals. Touching of the puffins feathers can remove the protectant oil they need to keep their feathers watertight while swimming. So even though they are adorable and cuddly keep from touching them and just enjoy the view.
