Birds - a class of warm-blooded egg-laying vertebrates, whose members are characterized by the fact that their body is covered with feathers and forelimbs modified into organs of flight - the wings (species that do not fly, have underdeveloped wings). Initially, the body structure is adapted to the flight of birds, although now there are many kinds of flightless birds. Another distinguishing feature is the presence of birds beak.
For today in the world there are more than 9792 different species, including the territory of Russia - 657 nesting species, but only in the country noted 789 species, including 125 species nesting which is not shown, and 7 of extinct species, making them the most diverse a group of four-legged superclass. Birds inhabit all ecosystems of the globe, from the Arctic to the Antarctic. The science that studies birds is called ornithology.
Birds are well-isolated group of warm-blooded vertebrates.
One of the most characteristic features of Representatives which is the covering of feathers that protects the body from adverse changes in temperature and plays an important role during the flight. The ability to fly is a major feature of birds (no such ability in some modern birds - a secondary phenomenon). All birds lay eggs. Upper limbs have taken the form of wings, and the birds are usually able to fly, although there are exceptions - the owls, penguins, and a number of island endemics in the course of evolution, have lost the ability to fly. Birds have a special structure of the respiratory and digestive system, which is closely linked to their ability to fly. Some birds, especially crows and parrots, have the ability to learn quickly.
Many species of birds make regular long flights from one region of the Earth to another, and even more nomadic, constantly moving over short distances within the range. Birds are social animals, communicating with each other using a visual and audible signals and perform a public action - such as communal nesting, joint hunting and protection from predators. For most typical "social monogamy" - pairs are formed on at least one or a few breeding seasons, some groups of birds for life. Among the forms of marriage are also found polygyny (when the male cohabits with several females), and in rare cases, polyandry (one female and several males). Typically, the eggs are laid in a nest and incubates both members of a couple. Most of the birds for a long time caring for the offspring after birth.
