Author: Fedor Ivchenko I think you must have already seen flying birds under the ceiling of some metro stations in Moscow. It is usually small pigeons or sparrows. But there is a big and a very old bird living in the Moscow underground. It is many millions years old. However, not many people know about it, even though they can see it every day! The bird is silently observing people all the time and follow them and trains with its haughty eyes. You will ask me: who is that bird???
