This is a still evolving taxonomic class that may or may not include the genera Procellaria and Bulweria.This list includes them both.

With so many different species, it is no wonder that there are endless fun facts about these birds. Shearwaters (Procellariidae) The Shearwaters (The Procellariidae) are the largest and most diverse group of Petrels. These two species can at times be seen in very large numbers, even from shore in Newfoundland in summer and early fall. Each species incubates their egg or eggs for different periods of time. Consequently, different species fledge at different rates as well. How many Shearwaters are there today? For example, in this week’s other family, the Shearwaters and Petrels, take a look at the Sooty Shearwater (page 234), another pelagic species that is common off both the Atlantic and Pacific coasts of North America. This depends on the species and where its breeding grounds are located. The Wedge-tailed Shearwater is the largest of the tropical shearwaters. There are many types of auks, but with their compact bodies all are well adapted to northern seas and colder waters. Taken altogether the worldwide Shearwater population numbers in the millions. The species most likely to be seen are Great and Sooty Shearwater. Many declines ar Pick a species that is near you, or one that looks striking, or one that has a strange name, and explore. Unlike many marine birds, albatrosses also walk well on land. They are strictly marine, many coming ashore to breed in burrows, then only under the cover of darkness, although one of the most widespread, the fulmar, nests on open ledges. There are many small petrels, as well as larger species, and many other kinds of shearwaters worldwide. Here's a list of Albatross species. Shearwaters are drab, slender-billed birds that range from 35 to 65 cm (14 to 26 inches) in length. In total there are 22 species in the albatross family, of which 17 are Globally Threatened according to BirdLife on behalf of the IUCN Red List. The name […] There are 22 albatross species in the world, all of which are part of the Diomedeidae bird family. 02 of 12. Shearwaters are medium-sized long-winged seabirds.There are more than 30 species of shearwaters, a few larger ones in the genus Calonectris and many smaller species in the genus Puffinus.The Procellaria petrels and Bulweria were believed to belong to this group, but are only distantly related based on more recent studies, while the Pseudobulweria and Lugensa "petrels" are more closely related.

There are two colour morphs of the species, dark and pale; the pale morphs predominate in the North Pacific, the dark morph (genetic mutation) elsewhere. Do Shearwaters have any natural predators? There are many small petrels, as well as larger species, and many other kinds of shearwaters worldwide. Typical shearwaters are classified in the genus Puffinus, which has approximately 20 species. "And if they’re not reproducing, the numbers will continue to plummet." “One minute there are 30,000 birds flying around in a colony, and the next thing you know, they’re down to 10,000," s ays Peter Barrand, president of BirdLife Warrnambool. Auk . ‘While there are few wild animals in Iceland, there is abundant bird life - ducks, geese and, among the many sea-birds I spotted, petrels, puffins, tern, gannets, skuas and shearwaters.’ ‘Next stop was at Collieston for a spot of lunch and some sea watching, following encouraging reports of big movements of petrels and shearwaters.’ However, both morphs exist in all populations, and bear no relation to sex or breeding condition.

However some individual species face extinction with numbers only in the low tens of thousands. There are simply too many different species of these birds to generalize their breeding habits.

The 66 or so species (the taxonomy of both Prions and Gadfly petrels is uncertain) can be divided into four subgroups: Fulmars (7 species), Prions (about 6 species), Gadfly Petrels (about 30 species) and true Shearwaters (23 species). This is a list of birds that belong to the shearwater group, of the family Procellariidae and the order Procellariiformes.. Raine points to an area he calls Nesh Corner, "nesh" for Newell's shearwaters because so many downed birds have been found there. In addition to regular species like Black-footed Albatross and Fork-tailed Storm-Petrel, our trips feature seasonal species such as Laysan Albatross, Flesh-footed, Short-tailed, and Buller’s Shearwaters, and South Polar Skua among many other offshore species. There have been many times when rafts of 20,000 Sooties and similar numbers of Greats have been reported. Seabirds, particularly member of the albatross family, are becoming increasingly threatened and at a faster rate globally than all other species-groups of birds; they face a wide variety of threats.
