Paragraph on "The birds - Man's best friends"

There are many birds on the earth. Most of them we see around around us. They live in nature and help us in many ways. So we can say that the birds are our friends. All the birds have peculiar shape. They live in nests made on the trees or in the trees. They get food from the trees, plants, fields and forests. But they help us much. The insects are in the field. They are harmful to the crops. These birds kill the insects and save our crops. You hate the crow. But do you know what is its food ? The crow eats dirty things and cleans the nature. How do you feel when the cuckoo sings ? Do you know that peacock is an enemy of snake ? It is our National Bird. The pigeons carry the message. The cock crows early in the morning and we get up. Thus we can say that the birds are our best friends. Shall we be kind towards our these friends ?
