The Arctic Tern is known for traveling at least 25,000 miles each year during its migration from its breeding grounds in the Arctic to its wintering grounds in Antarctica. This makes it the bird species with the longest migration in the world. Another bird species known for traveling long distances each year is the Bar-tailed Godwit, which travels approximately 11,000 miles each way between Alaska and New Zealand. These remarkable migratory birds rely on their incredible endurance and navigational skills to complete their journeys, which can take many months to complete.
