Vintage Edition of The Sibley Guide to Bird Life & Behavior is a book by David Allen Sibley that shows readers “how birds live and what they do." It is different from most field-identification guides that birdwatchers carry around; rather than help identify birds, it helps watchers gain a deeper understanding of the birds they have already identified. Instead of concentrating on individual species, the book summarizes information for families of birds, presenting "broad patterns" to help readers interpret what they see." The guide includes nearly 800 of Sibley's paintings. Excellent condition, minor signs of wear on the paperback cover, but the book is in fantastic shape.
