Dr. Seuss books have been enjoyed by kids for decades- I remember reading and reciting them years ago. What makes them so fun? You can't help but repeat the rhymes, over and over again. Plus, the illustrations are just simply delightful. This is part of the Dr. Seuss Cat in the Hat Learning Series for pre-schoolers and toddlers who are a bit too young for the bigger books. This book introduces children to birds.
