Get it!
Great book! Possibly a little too large to take conveniently to the field but it has all the good points of the earlier Peterson guide with improvements. Maps on the page with the birds is one that makes a difference. Over the years, as a casual birder I began to realize that birding is not static, names and ranges change and the only way to keep up is to update your reference library.
This is a great update, and upgrade, of a previous classic that celebrates the joy that birding brings to our lives.
