Ostriches are amazing birds. To begin with, they are one of the few birds that cannot fly. Even their anatomy is unusual, since the ostrich has no wishbone. Dr. Zim explains the unique bone structure of the ostrich and many other striking facts about this large bird, which can weigh up to 350 pounds! You'll learn about the ostriches' relatives—the extinct moas, the tiny kiwis of New Zealand, plus cassowaries, emus, rheas and more. Did you know that ostriches have two toes, rheas have three and kiwis four? Dr. Herbert Zim was a naturalist, author and educator. He wrote or edited more than 100 books on science and nature study, which are prized for their accuracy and  engaging material. Illustrated by Russell Francis Peterson.
