Where and how do birds live? Where do you fly to winter and when do you return to your native land? What are they "talking about," how are they watching and what are they seeing? How many live and why die? What do they eat and how do they raise their offspring? All these and many other questions are answered by the book of the famous ornithologist N.A. Gladkov. The whole book is imbued with the author's love for his native nature, concern for the protection and rational use of its riches.
