Useful and harmful birds: V. Duvanov

The world of birds inhabiting our planet is huge and diverse. Over 600 types of these amazing creatures are nesting in Russia alone. They more often than other living creatures attract our attention to themselves: someone with an unusual plumage, someone in a voice, and someone with their rapid or hungry flight in the sky. And I want to know what kind of bird it is, it is useful or harm. The question of the benefits and dangers of birds gives rise to many controversy, since birds can be both useful and harmful throughout the year. It is usually believed that if the bird is predatory, it means harmful. Is it really so? After all, we sometimes forget that birds take the most direct part in the biological processes taking place on Earth. This publication will allow the reader to get to know the world of birds better and, possibly, get answers to questions of interest to him.
