The Laysan Albatross and Black-footed Albatross are two of the 3 species of
albatross that occur in Alaskan waters. Albatrosses are by far the largest seabirds found
in Alaska, but are small compared to many other albatrosses. Laysan, Black-footed, and
Short-tailed Albatross have a wingspan of almost two meters, which is half that of the
largest albatrosses. Albatrosses do not nest in Alaska but they migrate here each year
after having bred in such far away places as the Northwestern Hawaiian Islands and
Torishima Island in Japan. On these remote uninhabited islands, albatrosses nest in huge,
dense colonies. Nearly all of the 400,000 breeding pairs of Laysan Albatross and 50,000
pairs of Black-footed Albatross nest in the Northwestern Hawaiian Islands. The Latin
family name for albatrosses is Diomedeidae, which comes from the name of the Greek
hero of the Trojan War, Diomedes. The Greek gods exiled Diomedes to an isolated island and
turned all of his companions into large, white birds resembling swans.

Albatrosses are truly at home soaring over the open ocean. Since the first humans
encountered albatrosses at sea, they have marveled at their mastery of the ocean despite
the harshest North Pacific storms. They travel great distances in search of food by riding
currents of air that flow just above the surface of the water. With their long, narrow,
pointed wings stiffly outstretched they soar effortlessly up and over the peaks of the
highest waves only to plunge gracefully into the next valley, all with only the twist of
the tail or tilt of the head, and only the occasional wingbeat. When albatross return to
their breeding colonies, they are not quite as graceful. They approach the island at high
speed, pulling up only at the last moment, often times skidding to a stop on their chests.
These "crash" landings combined with their strange and elaborate courtship
dances, and their lack of fear of people has resulted in them being called "gooney
birds" and aho-dori or "fool birds" in Japanese. Anyone who has closely
observed these majestic birds on land or watched them at sea, knows how unfair these names
are.
Today, most of the breeding sites of North Pacific albatrosses have been preserved and
it is illegal to intentially kill albatross. However many Laysan and Black-footed
albatross are killed every year as a result of human activities. Long-line fishing is one
of the causes, but this problem may be small compared to others. When albatross see small
pieces of plastic floating on the surface of the water they will often mistake them for
food and eat them. This plastic builds up inside the bird and can eventually prevent the
bird from feeding properly. Breeding colonies are often covered in plastic debris and
piles of plastic mark where birds have died and their bodies have decomposed. There is
also concern for the levels of some toxic pollutants in the bodies of albatrosses.
