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 un ique bone structure of the ostrich and many other striking facts about this large bird, which can weigh up to 350 pounds! The ostrich has many relatives-the extinct moas, the tiny kiwis of New Zealand, plus cassowaries, emus, rheas, and more. Did you know that ostriches h ave two toes, rheas have three, and kiwis four? Dr. Herbert Zim was a naturalist, author, and educator. His books are prized for their accuracy and engaging material. Show more
