　　Crows are much noisier than other birds．Very often a large number of crows will get together on one house and talk．Sometimes they talk together, and sometimes they do it by turns likes humans．It is easy to tell from crow's sounds whether they are happy or angry．Perhaps crows talk a lot because they are friendly birds．A pair of crows will live together all their lives, and if one them dies, the other becomes very sad and quiet for the rest of its life and sometimes it dies, too．
