Their debut calendar surveys the astounding variety of North American birds, spotlighting a new species every month in a clean, modern spread that is amplified by crisp, colorful illustrations--like a taxonomy of Warblers, including the Golden-cheeked, the Blackburnian, and the Orange-crowned. With fascinating facts throughout: Did you know that hummingbirds' wings move in a figure-8 pattern, and can reach a speed of 34 mph in flight?
