Sun-loving robins like open-air houses. Homebody house sparrows prefer a roof over their heads. Friendly purple martins love to live together in sky castles. Just like people, birds need a space to call their own. The nine birdhouses featured in this book require only basic woodworking skills and easy-to-find or recycled materials. Illustrated step-by-step instructions will help kids -- and parents -- turn their backyards into regular bird havens!-- Provided by publisher.
