Earthflight - Season 1 Episode 1 North America

Take off in a ‘snowstorm’ of geese and glide under San Francisco’s Golden Gate Bridge with pelicans. This is the world on the wing – a world with secrets known only to the birds. The countdown to Earthflight’s epic adventure begins in the Gulf of Mexico as five million snow geese prepare to fly the entire length of North America. Each spring, these families of geese head north on a gruelling 3,000-mile journey to the Arctic to breed.
