Book excerpt: This is the authorized guide to the Maine Birding Trail, which opens in 2009. The book features more than 260 sites in Maine and includes bonus material on Campobello and Grand Manan islands. Unlike most guides, which emphasize species identification, this book highlights the sites themselves. Bird enthusiasts will count on it to lead them to the best birding locations in Maine and to list the species they will most likely find at each destination.
