Let me answer this question the best way that i can. Can we really get so many words to explain what a bird is, but we can incooperate everything. A bird is an animal that is vertebrate, it lays eggs, has wings and webbed feet. Birds are known to fly, and others are on land. We also have birds that are domestic and otherrs are known to be wild. If i can explain the different types, we have chikens, peacocks, geese, ducks, ostrich and so on. They are eaten and they all lay eggs. We all know that ostrich eggs are the largest of them all. The birds of the air are of many types, we have the eagle that is the master up there and very dangerous. We have crows, owls, bats, the small singing birds, doves they are quite a number, and a good site to behold.
