About albatross

Albatross are legendary birds for many reasons in Samuel Coleridge's poem, "The Rime of the Ancient Mariner," a sailor has to wear an albatross around his neck as punishment for killing the bird. According to seafaring legends, albatross are the souls of lost sailors and should not be killed. However, as reported by James Cook, sailors regularly killed and ate albatross.

Albatross are remarkable fliers who travel thousands of miles on wind currents without ever flapping their wings. They do this by angling their 6-foot wings to adjust for wind currents and varying air speeds above the water.

Nineteen of 21 species of albatross are threatened with extinction, according to the International Union for the Conservation of Nature. Present threats to the birds include lead poisoning of chicks on Midway from lead paint used in previous decades; longline fishing, where the birds are inadvertently hooked and drowned, though conservation groups have banded with fishermen and dramatically lowered the number of deaths from this cause; and pollution, especially from garbage floating on the ocean.

The birds ingest large amounts of marine debris by some estimates 5 tons of plastic are unknowingly fed to albatross chicks each year by their parents. Although the plastic may not kill the chicks directly, it reduces their food intake, which leads to dehydration and most likely lessens their chance of survival. In addition, albatross are threatened by invasive species such as rats and wild cats, which prey on chicks, nesting adults and eggs. Albatross evolved on islands where land mammals were absent, so have no defenses against them.
