This page is intended to
only be an introduction to endangered sea birds of our world. The species
presented below are by no means the only ones in danger. Links at the bottom of the page
will take you to some of the best resource sites out there for more in-depth
information. The best sites to start with are marked with a star
Many species of sea birds, including the delicate Roseate Tern shown above, are disappearing and endangered for a variety of reasons, including breeding site disturbance, disease, habitat loss and pollution. And most of these have man as the source. An additional grave threat to albatross and petrel species worldwide is longline fisheries. The list of species that are threatened or endangered is long, and growing daily. Some of the more well known oceanic birds that now face extinction are various albatrosses, petrels, terns, eiders, sea eagles, penguins and pelicans.
"Albatrosses, the most
spectacular breed of bird known, are fast dying out, it has been reported within
the last few years that up to 1,000,000 albatrosses are killed per year mainly
by being caught on fishermen’s long lines, though some countries, e.g. South
Africa, are trying to prevent this. The worst sufferer is the black-browed
albatross from the Falkland Islands whose feeding grounds coincide with
long-line fishing grounds where a thousand albatrosses a day have been reported
killed. Large numbers are killed by New Zealand Tuna-fishing boats as well as
long liners. Japanese tuna longliners fishing under license in New Zealand
waters were counted as killing an average of 904 per year between 1988-89
(Journal of Applied Ecology, 40:4,678).Birdlife International reports 2 species
as being critically endangered, 3 endangered and 12 species as vulnerable. We
can expect that as usual really stringent protection will be brought in when
they are extinct. We seem hell bent on creating a pretty dull world for
ourselves!
Petrels are small (5-6") pelagic birds that only come ashore to
breed. Tireless fliers by day, at night they rest on the water. Many petrels fly
over the water skinning so closely that they give the appearance of walking on
water. Effortless fliers, Petrels are capable of incredible transequatorial
migrations, with some species flying from the Gulf of Alaska to nesting sites
far into the Southern Hemisphere. Endangered petrel include the following
species: Magenta Petrel, Fiji Petrel, Reunion Petrel, Chathams Islands Petrel,
Barau's Petrel, Beck's Petrel, Jamaica Petrel, Zino's Petrel, Galapagos Petrel,
Bermuda Petrel, Black-capped Petrel, Hawaiian Dark Rumped Petrel, Heinroth's
Shearwater, Newell Townsend's Shearwater and Hutton's Shearwater. Terns are slim and graceful birds, quite similar to gulls and below to the same family, Laridae. Terns have long, gray wings and webbed feet and are usually smaller than gulls and have sharp-pointed bills and forked tails. They are much quicker than gulls and can hover gracefully, always flying with their bills pointed down at right angles to the water. Because of their small webbed feet, terns cannot swim well and are seldom in the water longer than it takes to catchs ome food. Endangered species include the Roseate Tern, Least Tern and California Least Tern Eiders are sea ducks found across the artic and subartic zones of the northern hemisphere. There are only four species in the world, and all breed in Alaska. the common, king and spectacled eiders are among the largest ducks found in North America, while the smaller stellar's eider is one of the most unique member of the duck family. Both the spectacled and stellar's eiders are endangered. Eiders have the physical characteristics of diving ducks, and typically the males have bold plumage pattersn of black and white, while the females are muted black, grey and brown. The ducks have commerical importance and their fluffy underlayer of feathers known as down, or eider down, is an excellent insulator and is collected from nests on "eider farms" in Iceland and Scandinavia and marketed in sleeping bags and comforters.
