Asfall approaches, the birds of summer vanish from our yards and woodlands. Have you ever wondered where they go in winter? How they know when it is time to leave? And how they find their way to winterhomes and back again without a compass or a map?Through her clear and well-researched text, naturalist Carol Lerner explores the migratory patterns of our American birds. She captures the birds' beautiful colors and markings in her vibrant, realistic paintings. Budding birders can compare these images to the flocks they spot in the sky, while more experienced ornithologists will also enjoy studying the colorful maps that show the summer and winter ranges of these migrants.On the Wing will help anyone's interest in bird-watching take flight.
