In 1941, there were only 21 whooping cranes left; but thanks to 40 years' worth of effort by scores of scientists and naturalists, this endangered American species has made a dramatic comeback. The struggle and success are captured here in an engaging text and 50 vivid photos. Patent focuses on birds in refugees in Texas and Idaho and on the captive breeding program in Maryland; she also describes the cranes' life in the wild. While some of the material here is so condensed that the transitions can be over-abrupt, the story itself is fascinating; Patent conveys the enthusiasm, ingenuity, and scholarship of the people who contributed to preserving a unique and lovely species.
