What to read after Birds?

The Wonderful World of Animals series focuses on the common characteristics of the major animal families. Its goal is to give children a broader understanding of similarities between animals that seem very different from each other at first glance, such as horses and cats. Basic concepts in biology and physiology are presented to help children recognize similar traits and features of animals of the same family. This excellent series is a complement to the more typical wildlife series whose volumes focus on single animals.

Birds come in all colors, shapes, and sizes, from tiny bee hummingbirds no bigger than a man's thumb to huge ostriches nearly 10 feet (3 meters) tall. However, all birds have four common characteristics: they lay eggs and have beaks, feathers, and wings (although not all of them can fly).
