The crow is an ordinary bird.It is about twenty inches long and black all over.Crows are dirty because they live on old bad food.Crows eat a lot of waste food.In this way they are more useful to us than any birds.They clean up the dirty things in our streets.Crows are always hungry.They look for food all day long,and in the evening you can see them in large numbers flying back to their nests in the trees.They sleep there at night.
Crows are much noisier than other birds.Very often a large number of crows will get together on the house and talk.Sometimes they talk together,and do it by turns like human beings.It is easy to tell from crow’s sounds whether they are friendly birds.A pair of crows will live together all their lives,and if one of them dies,the other becomes very sad and quiet for the rest of its life and sometimes it dies,too.
