Welcome to the World of Otters

These are the latest titles in this popular series that introduces children to North American wildlife through color photographs and fascinating text. Young readers will be enchanted by America`s smallest bird, the fearless hummingbird. Its resting heart rate is an astonishing 480 beats per minute and, unlike any other bird, it can fly backwards.

This book reveals their origins, their complex family systems, and how they live together off the land.
