Indian birds

A bird is an animal belonging to the class of vertebrates, warm-blooded and feather-covered. The birds have wings and legs, and have a head with a beak without teeth. They are generally suitable for flying but some species, such as the ostrich, can not fly. They lay eggs to reproduce. There are about 10,000 species of birds. A bird can be domestic or wild. It is an oviparous animal. The ostrich is also the largest bird in the world and the largest egg in the world. The little bird is the fledgling.
Archeopteryx, a lost bird, is the oldest known bird. Several fossils have been found. Birds are part of a larger group, the dinosaurs, a

group that includes birds and many fossil species that have disappeared. Dinosaurs such as velociraptors, or oviraptors, are the closest relatives of birds. This means that in reality the dinosaurs have not all disappeared since the birds are still dinosaurs, even if they are very transformed dinosaurs (the birds in their current form have also appeared well before the disappearance of the other dinosaurs ).

Food
The diet depends on the environment and the species:
• Raptors feed on small animals and rodents
• grain-eating birds feed on seed sets,
• Insectivorous birds feed on insects such as worms,
• Birds wading frogs or small rodents, but the flamingo filters the water with its beak.
• Waterfowl feed on algae or particles in the mud.
• Some birds are scavengers, which means that they feed on dead animals.
• Hummingbirds or hummingbirds feed by absorbing the nectar of flowers with their long, thin beaks.
The high metabolism of birds forces them to consume large amounts of energy. Some birds such as thrushes consume 40% of their weight. Swallows consume 100%, and hummingbirds 200%. But there are many kinds of animals that eat many things.
