With Mom feeding him insects and nectar, Ruby T. Hummingbird is soon able to beat his wings and fly—up, down, backward, and forward—and forage for himself. But don't be fooled! This elegant creature can turn into a fierce fighter if another hummingbird tries to feed on his flower—or his hummingbird feeder. A second test of his strength comes when he migrates to a warmer climate in the fall and a cooler climate in the spring. Children will love poring over the bright, highly detailed illustrations and pondering ideas about nature. The book includes a glossary and further information in the back of the book. Both art and text have been vetted for accuracy by an expert. Don't miss the other books in The Nature Diary Series! Each one explores the life cycle of an animal in dated journal entries, showing young readers how they grow and change through the seasons— and offering a few laughs, too!
