Birds are a group of endothermic vertebrates constituting the class Aves. They are characterized by feathers, toothless beaked jaws, the laying of the hard-shell eggs and other specifications. Plumage

also varies widely, and in many species, the male is brightly coloured for courtship display whereas the female is drab.

Each bird has its own specialties and difference in its structure. Some are small and some are big in their size. Feathers are the defining characters of Aves, found on every living species of bird and no other class of animals. All birds have wings, although not all birds fly.

Birds live in diverse habitats like Mountains, Deserts, Forests, near the bodies of water, Tundras, etc. Some birds migrate during the changes in weather, others do not leave their living place ever.
The migration of these birds took thousands of kilometers long. Many bird's bones are hollow, so they could be lightweight. Birds have feathers that help them fly. The long flight feathers on the wings and tail help birds to balance and steer.
