An advertisement for General Telephone and Electronics by which a narrator describes the work of Sylvania Lighting while a rapid succession of shots play displaying various ways the products are used.
New York Zoological Society, National Film Board of Canada
Summary:
In their routes of migration, birds "mock the man-made lines by which nations separate themselves," as the narrator states in this film intended to foster goodwill between the nations of the Americas. Two boys, Richie in the North and Ricardo in the South, both feel ownership of the barn swallows that reside in their respective homes at opposite ends of migratory routes. Aerial photography follows Canada geese migrating from northern Quebec to the Chesapeake Bay. Technically advanced high speed photography reveals the beating wings of the ruby-throated hummingbird. The bird banding and migratory data-collecting work of the U.S. Fish and Wildlife Service is explained. Animated maps of the hemisphere illustrate some of the long-distance bird migration patterns between North and South America.
