In one of the most amazing wildlife spectacles on the planet, millions of birds migrate each year between their breeding and wintering grounds, undertaking journeys that are remarkable feats of navigation, yet incredibly dangerous.
Migrations can span vast distances, such as the bar-tailed godwit's single flight of nearly 7,000 miles (11,000 kilometers), or the Arctic terns, which over the course of their lifetimes travel the same distance as going to the moon and back — three times. Some of them return year after year to the same location, navigating across a planet now vastly changed by humans.
