 Albatross - Wikipedia, the free encyclopedia
Numbers of albatrosses have declined in the past due to harvesting for feathers, but today the albatrosses are threatened by introduced species such as rats and feral cats that attack eggs, chicks and nesting adults, pollution, and long-line fishing.
All albatrosses range in the southern hemisphere except for the four North Pacific albatrosses, of which three occur exclusively in the North Pacific, from Hawaii to Japan, California and Alaska; and one, the Waved Albatross, breeds on the equator in the Galapagos Islands and feeds off the coast of South America.
Albatrosses are colonial, usually nesting on isolated islands; where colonies are on larger landmasses they are found on exposed headlands with good approaches from the sea in several directions, like the colony on the Otago Peninsula in Dunedin, New Zealand.

 Albatross, South Georgia  -  Travel Photos by Galen R Frysinger, Sheboygan, Wisconsin
Albatrosses are among the most spectacular gliders of all birds, able to stay aloft in windy weather for hours without ever flapping their extremely long, narrow wings.
The growth of the young albatross is very slow, especially in the larger species; it attains flight plumage in 3 to 10 months, then spends the next 5 to 10 years at sea, passing through several pre-adult plumages before coming to land to mate.
Seamen once held albatrosses in considerable awe; they held that killing an albatross would bring bad luck, a superstition reflected in Samuel Taylor Coleridge's poem “The Rime of the Ancient Mariner.” In spite of this superstition, the birds were often taken on baited hooks by sailors for meat.

Albatrosses are predatory and they bring food to their young in the nest, so it is not a surprise that they have a small clutch size.

The Black-footed Albatross (Diomedia nigripes) is one of two species of Albatross that nests annually in the Hawaiian Islands, and one of three that occur regularly in the North Pacific (the other species being Laysan and Short-tailed Albatrosses).
Most Laysan Albatrosses manage to find their way back to the island on which they were born, with only a few birds travelling to other areas; these "lost" birds however, may be the colonisers of new breeding grounds, helping the species to spread to other island-chains.
Laysan Albatrosses do not exhibit strong territorial behaviour and will only make bobbing and lunging motions to show where their nest site is, however once the chicks have hatched Black-footed Albatross may approach them and attack them quite ferociously, resulting in bloody patches on the necks of juveniles.

 Laysan Island
In some ways Laysan Island is the most fascinating and in some ways the most unfortunate of all the tiny dots of land in the "little end of Hawaii." In former days it supported the largest albatross rookery of the entire chain.
Laysan is located 790 sea miles to the northwest of Honolulu, in latitude 25 degrees 42' 14" North, longitude 171 degrees 44' 04" West of Greenwich.
Thus, when a party of Japanese poachers landed on Laysan and Lisianski in the spring of 1909, they were promptly arrested by the revenue cutter Thetis and taken to Honolulu for trial.

Historically the population of Laysan Albatross has been very large, with many millions of birds present, however after suffering heavy losses through hunting, military development and accidental losses at sea through long-line fishing, the population is currently estimated at about 2.5 million.
Laysan Albatross do not start breeding until they are eight or nine years old, with males starting a year earlier than females.
All Laysan Albatross are protected on land in the Hawaiian Islands and off continental America, with most colonies situated on islands with restricted access and so these populations should be safe from most influences except unusual or severe weather.

 LONGEVITY OF THE LAYSAN ALBATROSS, DIOMEDEA IMMUTABILIS
In their entirety, and without any further theoretical extensions, the data on the Laysan showed a minimum percent survival of adults to various minimum ages as follows: 13% to 20 years, 24% to 25 years, 9% to 30 years, 2% to 35 years, 7% to 38 years, and 3% to 40 or more years.
In summary, we may generalize that observed longevity in the Laysan Albatross is in the general order of 13% to 20 years, and, summing the data of Table 2 into a single sample of 742 albatrosses, we obtain the percentages indicated (Table 3) for birds 30 or more years of age.
For a long period the only definite information on the length of life among albatrosses was the classical example of the Black- browed Albatross (D. melaophris), which lived among the gannets of the Faeroe Islands for some 34 years (Murphy, 1936' 511).

 PCBs, DDE, DDT, and TCDD-EQ in Two Species of Albatross on Sand Island, Midway Atoll, North Pacific Ocean - ...
The Laysan albatross diet consists primarily of ommastrephid squid (68% of the diet); the remainder of the diet consists of approximately 9% fish, 9% crustaceans, and 4% coelenterates [7].
For Laysan albatross adults, total concentrations of PCBs and DDE were greatest in the spring of 1993, whereas the fall 1992 sample period had less total PCBs than the other periods (Table 2).
In 1969, concentrations of PCBs and DDE in visceral fat of Laysan albatrosses were 22.3 mg/kg and 13.7 mg/kg, respectively; whereas visceral fat of fl-footed albatrosses contained a mean concentration of 15.3 (7.5-21.3) mg/kg and 15.3 (5.1-22.7) mg/kg of PCBs and DDE, respectively.
