Book about birds photography

Visiting EMPiK recently I came across very interesting book (unfortunately in polish) called "Fotografujemy ptaki" written by the most famous polish birds photographers - Klosowscy brothers. I bought this book immediately and read it over the weekend. It's really nice and interesting considering not only perfect bird pictures, but also description of birds, technology required to get good results, methods of bird photography and even law aspects of bird's nest and similar things. I'm surprised that this book sprung into existence, because it's complicated and touchy topic. Publication is very smart and present very intelligent and balanced approach to the subject. You can learn a lot and get knowledge from the most experienced polish bird photographers. Congratulations!!!
