  Albatrosses are among the most fascinating of all gliders, able to stay aloft in inclement weather for hours without flapping their extremely long and narrow wings. In calm air, the albatross has trouble maintaining its strong body in the air and prefers to rest on the surface of the water. Like other oceanic birds.

albatross food

 Albatross gets its food from the sea, such as fish and squid, and it has the ability to drink salt water. Although albatrosses usually subsist by hunting squid, they are also seen escorting ships to feed on their litter.

 

Reproduction and life cycle

Albatrosses come ashore only to breed. This activity occurs in colonies usually established on islands of the distant ocean, where groups and pairs exhibit mating behavior that includes displaying wing stretching and beak fencing accompanied by loud moaning sounds. A single large white egg, laid on the ground or in a stacked nest, is incubated by the religious spouses in turn taking care of the nest. The growth of the young albatross is very slow, especially in the larger species; Flight feathers grow within 3 to 10 months, then spend 5 to 10 years at sea, passing through several feathers before coming on land to mate. Albatrosses are long-lived and may have an average lifespan of around 50 years.

 

Threats

The sailors once caught the albatross in great awe; They held that killing an albatross would bring bad luck, a superstition reflected in Samuel Taylor Coleridge's poem "The Frost of the Old Navigator". Despite this myth, sailors often took birds on baited hooks for meat. At one time, professional hunters raided albatross breeding areas. North Pacific species were slaughtered in large numbers for their feathers, which were used in the hat trade and as mold for swans.

 

 Some types of albatross

The black-browed albatross, with a wingspan of about 230 cm (7.5 ft), wanders offshore in the North Atlantic. She has a dark eye line that gives her a frowning look.

The black-footed albatross, one of three species from the North Pacific, has a wingspan of about 200 cm (6.5 ft) and is largely dark brown. It is located in the tropical Pacific islands and roams widely throughout the North Pacific Ocean.

Lysian albatross, which has a wingspan of about 200 cm, has a white body and dark upper wing surfaces. Its distribution is almost the same as that of a black-footed albatross.

The royal albatross, which has a wingspan of about 315 cm (about 10 feet), is largely white with black outer wing surfaces. It breeds on islands near New Zealand and near the southern tip of South America.

The marbled albatross has a wingspan of about 215 centimeters (7 feet). They nest on islands in the southern oceans.

The wandering albatross also has the largest wingspan of any living bird - it can reach more than 340 cm (11 ft). It is basically like a royal albatross. It nests on islands near the Antarctic Circle and on some islands in the South Atlantic, and in the non-breeding season it roams the southern oceans north to about 30°S.
