Query: At Last! Something that actually contributes to the Field!

Call me cynical but in the last twenty years I have seen field guide publishers recylce the same old info over and over again, just adding a new tabulature or color photos. The text is minimal and always leaves me wanting more.Not so with this book! Mark and Eleanor have created something that goes well beyond any field guide currently on the market concerning birds! This stuff is new and never before seen except for experienced birders in the field. It is easy to use, fun to use and it will help anyone learn more about birds, their habits and sign. The photography is stunning as well.I cannot over-recommend this book. Go get it, now!Ricardo Sierra
