The song of birds is one of the most wonderful sounds. Probably the best singer is the nightingale. Sometimes when we are out in the country, we hear birds making some sounds and we may think they are telling one another something. The fact is that birds have their own language, just as many other animals do but their language is different from people`s language. We use words and people must know these words, they should learn them. Birds don`t learn their language.They are able to sing, "to talk" because they can make sounds and noises. It is an instinct with them. Let`s take a chick from its parents so that it can`t hear the sounds they make. When the chick grows up, it will still be able to make the same sounds as its parents. But birds can`t learn "other languages". Some birds like parrots, crows, jackdaws are talented imitators. They imitate the speech of people and other animals. A lot of birds can learn other birds` songs. For example, if a canary grows up with a nightingale, it can learn to sing like a nightingale. But this imitation is not a real language. Birds do not talk as we do.
