Migration Patterns and Navigation in Arctic Tern Populations
Quick fact
Arctic terns travel approximately 80,000 kilometers (50,000 miles) round-trip each year, the longest migration of any animal, and they may live up to 30 years, meaning they can fly the equivalent of three round trips to the Moon in their lifetime.
Why this is interesting
Imagine flying from the North Pole to the South Pole and back every year—without a map or GPS. How do Arctic terns accomplish this incredible journey?
