Flyways: the untold journey of migratory shorebirds

Shorebirds fly thousands of miles each year along ancient and largely unknown migratory routes called Flyways. Species travel from feeding grounds in the southern hemisphere to breeding grounds in the Arctic regions and back again, flying up to nine days non-stop without food or water. They are the world's greatest endurance athletes and their navigational skills on these marathon migrations are as extraordinary as they are mysterious.
