On an April day in 1953, renowned American ornithologist, author, and illustrator Roger Tory Peterson met his British friend James Fisher, an authority on seabirds, in Newfoundland. There they began a strenuous and thrilling hundred-day field trip around the edge of the continent. Part travelogue, part epic natural adventure, their richly illustrated record is "the superlatively good product of ideal circumstances" (Chicago Sunday Tribune).
