No other birds have as wide a distribution as the Procellariiformes. They are found in Antarctica as well as Greenland and in every ocean across the globe.
Tubular nostrils are common to every procellariiform (member of the order Procellariiformes). In the albatross, the nostrils stick out from both sides of the bill. In the other three families, the nostrils sit at the base of the upper bill. Procellariiforms differ from other birds in that they have a highly developed sense of smell, which helps them locate food and breeding sites. Procellariiforms…
Tubenosed seabirds are found mostly on islands with few land-based predators. Those that nest on the mainland do so primarily in deserts or mountainsides, where there are fewer predators. Because the larger birds need strong winds to help them get airborne, breeding sites must be windswept. This makes the sub-Antarctic islands perfect for breeding. Unless they are breeding, these birds spend their…
Larger seabirds such as the albatross eat mostly squid, though they snack on other seabirds and carrion, dead, rotting flesh, as well. They eat the carcasses of seals and whales while the smaller seabirds eat the leftover scraps. Only the larger seabirds look for food on land. All Procellariiformes take advantage of the behavior of whales, dolphins, sharks, and tuna. When these predators push scho…
Procellariiforms live in groups, even when breeding. Although their flocks often contain numerous species, fights occur frequently, with the larger species forcing out those smaller birds. Unless competing for food, most procellariiforms are silent on the water. However, when nesting on land, they communicate with shrieks and calls. These seabirds breed slowly, laying just one egg each season. The…
Because of their ocean habitat, procellariiforms have a long history of interaction with fishermen and seafarers. These birds help fishermen locate fish and other marine life. In addition, their archaeological remains have been found around the world. Today, only the shearwater species is eaten, as are the eggs of the petrel. Humans also use the feathers of the albatross in the hat-making industry…
Twenty-three of the 108 species are threatened with extinction. One species, the Guadalupe storm-petrel, has become extinct since 1600. The primary threat is the introduction of predators to the breeding islands. Prior to 1991, drift-net fishing was allowed. This is a type of fishing in which large nets were cast onto the waters and then hauled in. Although drift-nets efficiently caught large numb…
