With Paul Johnsgard, we follow the annual migration of the sandhill cranes from the American Southwest to their Alaskan mating grounds and then home again. It is a flight unaltered in nearly ten million years. By presenting various cycles of the migration in four time periods from 1860 to 1980, Johnsgard, a prominent naturalist, is able to show how man's encroachments have imperiled the flocks. In each section there is interaction between a child and an adult brought about by some ritual event in the migration of the cranes. The story is enriched by the author's exquisite illustrations, by Zuni prayers, and by Eskimo and Pueblo legends.
