How far do shearwaters travel?

Many shearwaters are long-distance migrants, perhaps most spectacularly sooty shearwaters, which cover distances in excess of 14,000 km (8,700 mi) from their breeding colony on the Falkland Islands (52°S 60°W) to as far as 70° north latitude in the North Atlantic Ocean off northern Norway.

What type of flight do shearwater have?

They are most common in temperate and cold waters. These tubenose birds fly with stiff wings, and use a shearing flight technique to move across wave fronts with the minimum of active flight. Some small species, such as the Manx shearwater, are cruciform in flight, with their long wings held directly out from their bodies.

What is a Shearwater’s habitat?

Despite having so many different species, the vast majority of Shearwaters share a habitat. Most species spend the greater part of their time on the open ocean, not even straying close to shore unless they are breeding. When the breeding season rolls around, their preferred habitat varies from species to species.

How many eggs does a Shearwater lay?

They nest in burrows and often give eerie contact calls on their night-time visits. They lay a single white egg. The chicks of some species, notably short-tailed and sooty shearwaters, are subject to harvesting from their nest burrows for food, a practice known as muttonbirding, in Australia and New Zealand.

How far do shearwaters travel each year?

Sooty Shearwaters travel an incredible distance each year, logging as much as 40,000 miles as they travel their circular route from their breeding colonies in the Falkland Islands in the spring to Arctic waters to feed throughout the summer, and back down to the breeding grounds in the fall.

Can a Shearwater walk on land?

Shearwaters can appear awkward and cumbersome when walking on land. Manx shearwaters nest in burrows and therefore prefer cliff slopes that have large stretches of turf. The Manx Shearwater feeds on small fish, particularly herring, sprat and sardines.

How many eggs can a bird lay at once?

Long-lived birds, such as many seabirds, may lay only a single egg, while some gamebirds and rails can lay clutches of twenty or more. Instances of egg-laying by multiple females in the same nest can lead to apparently larger clutch sizes in some groups, e.g. waterfowl and ostrich.

The electronic tags recorded birds diving to depths as great as 68 meters (225 feet) to capture their prey. Average dive depth was about 14 meters (46 feet). Sooty shearwater fly 65,000 km (39,000 miles) in a roundtrip journey each year. It is the longest recorded animal migration.

How far do sooty shearwaters fly?

Sooty shearwater fly 65,000 km (39,000 miles) in a roundtrip journey each year. It is the longest recorded animal migration. Contrary to previous assumptions, sooty shearwaters do not make a big pan-Pacific sweep to cover all of the feeding areas in the Northern Hemisphere.

What kind of birds can walk on water?

Ducks, geese, swans, gulls, and many seabirds and shorebirds have webbed feet (toes connected with flexible skin) that help them swim. Petrels can almost “walk” on water by pattering with their webbed feet while flapping their wings. Waterfowl use their feet as water-breaks when they fly down to land on water.
