Procellariiformes-shaped head (procellariiformes) in animal taxonomy is a Aves orders, including 4 families, 93 species. Most of the heads of the birds is a long narrow wings, short tail feathers of seabirds. They generally fly and hunt on the sea, many on the land only when feeding. All the world's climate regions form the purpose of marine birds have Procellariiformes.
Procellariiformes bird beak-shaped head straight long, in the end under the hook to form a phase. Their mouth is a multi-block parallel to the narrow horny composition. There are two tubes in the mouth, Procellariiformes birds use them to shape the purpose of excluding them into the drink to drink salt water. Some birds can Procellariiformes purpose of this two-shaped tube in an oil spray, using this method they can to fight back a few meters away the attackers.
Procellariiformes purpose of bird-shaped feet are webbed, toes after degradation or completely disappear. The purpose of many birds, Procellariiformes shaped almost can not walk on land, some only at night on the landing.
The purpose of all Procellariiformes-shaped birds to fish, squid, jellyfish and other marine animals for a living.
Procellariiformes form a large group of birds, the purpose of the hatchery, in general they do nest on the ground.
Procellariiformes purpose of bird-shaped, large sea birds. A powerful hooked beak, covered by a number of horny pieces; nose tubular, also known as tube-nosed type. Liang Chi long, sharp, good flight, almost all day long flying sea. Was convex or square tail end of the caudate. Webbed toe with the former, very small hind toe, or does not exist. Far on the island nesting ground or Yanya. As of late chicks.

There are 4 families of this project, China has 3 sections:
procellariidae - Procellariiformes Division
diomedeidae - Albatross Section
hydrobatidae - Haiyan Branch
pelecanoididae - pelican Yan Division
Common species are short-tailed albatross and petrel Heicha tail.
Procellariiformes-shaped head called tube-nosed type, is the real oceanic birds to adapt to fly in the vast ocean, a total of 3 to 4 families. Procellariiformes Passeriformes a wide range of very different size of its membership, which includes the largest of seabirds, including the smallest of seabirds.
Albatross Branch (diomedeidae): large Procellariiformes classes, fin extremely long, some species such as the wandering albatross is the largest wingspan of birds. Albatross adapt to ocean life extreme, life most of the time spent in the ocean, only to return the land during the breeding season. Albatross is an outstanding flight home over the SST in the ocean surf, you can not beat its wings a few hours. There are 13 species of albatross 2, China 1 3 species.
Procellariiformes Branch (procellariidae): mostly medium Procellariiformes class, about 13 genera and 55 species of seabirds and gulls tend to be the largest
Families, a very wide distribution, are distributed from the Arctic to the Antarctic, and in the temperature of the tropical South Pacific region in particular, most types.刊 COLLECTED PAPERS, storm petrels, similar and larger size, longer wings. China has a 4 to 5 is 7 ~ 9.
Haiyan Branch (hydrobatidae): small Procellariiformes class, is the smallest of marine birds, short rounded wings, flight
Wings when the high frequency is known to not be afraid of the stormy sea. In fact, the purpose of Procellariiformes-shaped birds are a master of using air, often flying through wind power. Swallow about 20 species of 8 genera most species in the Pacific, Atlantic type less, there is no distribution of the northern Indian Ocean. China has 2 genera and 4 species.
Pelican Yan Branch (pelecanoididae): small Procellariiformes class, also known as latent Procellariiformes, combines the characteristics of penguins and petrels, as
Penguins swimming as the water with wings flying ability was not lost. Pelican Yan is only distributed in the southern hemisphere, focusing on the subantarctic region, an extension to the Peruvian coast, a total of 1 genus and 4 species. Pelican is sometimes included in Procellariiformes Yan Branch Division. |
