content: I was waiting for this book to come out for a while and I got one of the first copies that came out. I am hugely disapointed. Ofcourse, the pictures are great and there are large paragraphs on physical description and plumage, but unbelievably, there are no range maps and the descriptions of habits, behavior and migration patterns are almost like footnotes after a page long dictionary like description of plumage. I compare this book to the similar princeton guide to north american sparrows, which has incredible descriptions of behavior and great rangemaps, and I call this book a massive disapointment. So if you want a page long summary of physical description, buy this book, otherwise save your money.
