 The cameras of Jacques Perrin fly with migratory birds: geese, storks, cranes. The film begins with spring in North America and the migration to the Arctic; the flight is a community event for each species. Once in the Arctic, it s family time: courtship, nests, eggs, fledglings, and first flight. Chicks must soon fly south. Bad weather, hunters, and pollution take their toll. Then, the cameras go south of the Equator; Antarctica is the summer destination. The search for food, good weather, and a place to hatch young takes this annual cycle of stamina across continents and oceans. There is a spare narration and a few titles; for the most part it s visual, a bird s eye view.
