Parrot Free Screensaver. Photos video summary. Bird screensaver. This free of charge screensaver contains many images of Bird. Birds (class Aves) are bipedal, warm-blooded, vertebrate animals that lay down eggs. There are about 10, 000 living types, which makes them the most many tetrapod vertebrates. They live in ecosystems around the world, from the particular Arctic to the Antarctic. Birds range in dimension through the 5 cm (2 in) Bee Hummingbird in order to the second . 7 mirielle (9 ft) Ostrich. Contemporary birds are characterised simply by feathers, a beak along with no teeth, the putting of hard-shelled eggs, the high metabolic rate, the four-chambered heart, and the lightweight but strong bones. All birds have forelimbs modified as wings and most can fly, with some exceptions including ratites, penguins, and a number of diverse endemic island species. Birds also have unique digestive and respiratory systems that are highly adapted for flight. Many species are of economic importance, mostly as sources of food acquired through hunting or farming. Some species, particularly songbirds and parrots, are popular as pets. Many species undertake long distance annual migrations, and many more perform shorter irregular movements. Birds are social; they communicate using visual signals and through calls and songs, and participate in social behaviours including cooperative breeding and hunting, flocking, and mobbing of predators.
