threatened procellariids world conservation
Procellariids live on oceans throughout the world, in the Northern and Southern Hemispheres.
Procellariids live almost exclusively on the ocean, coming to shore only to breed.
These nocturnal, active at night, birds eat squid, plankton, and marine life that has been discarded from fishing vessels. Giant petrels also eat seal and penguin carcasses.
Procellariid eggs and meat are eaten by people in a number of cultures, including Eskimos and Europeans. Every year several thousand chicks are harvested for their feathers, fat, flesh, oil, and down in New Zealand and Tasmania.
Some procellariid populations are thriving, but others are among the most threatened birds in the world. Forty-seven procellariids are on the World Conservation Union's (IUCN) List of Threatened Species. All are Threatened, facing a high to extremely high risk of extinction, or Near Threatened, in danger of becoming threatened. These species are considered threatened because of habitat deterioration as well as introduced, brought in by humans, predators.

Procellariids excel at flying, with equal ability to flap as well as soar, which makes finding and catching food easy. Shearwaters are named for their tendency to glide just over the water's surface. Like other Procellariiformes, procellariids vomit their smelly stomach oil onto enemies. This defense mechanism is used against predators during breeding season and against humans who get too c…
Physical characteristics: Manx shearwaters weigh anywhere from 12.3 to 20.3 ounces (350 to 575 grams) and are 11.8 to 15 inches (30 to 38 centimeters) long. Their wingspan is 29.9 to 35 inches (76 to 89 centimeters). The upper body is black with white underneath. Geographic range: Manx shearwaters breed mostly on the coastal cliffs around the North Atlantic Ocean, with a large population in Britai…
Physical characteristics: One of the larger shearwaters, the northern fulmar is about 18 inches (46 centimeters) long, with a wingspan of 40.2 to 44.1 inches (102 to 112 centimeters). Northern fulmars resemble gulls, with gray upper bodies and white heads. However, their wings are broader, and the neck is thicker. Their bill is yellow.
