In the tradition of Peterson's ABC of Birds follows Peterson's Numbers, the most recent delightful book for little bird watchers from author and designer Rudy Hoglund. Charmingly illustrated with paintings by Roger Tory Peterson, legendary bird authority and artist, this book will not only help young children learn their colors, but also foster interest in birds and nature.

Teaching children the importance of their part in the natural world has always been paramount in the career of Dr. Peterson. He provided leadership in the founding of the Roger Tory Peterson Institute of Natural History, whose primary mission is to provide educational programs to schools throughout the nation.

Recognizing birds as part of a child's life is a fun way to become acquainted with nature. We hope you enjoy Roger Tory Peterson's Numbers.
