The Quiz: What bird makes the longest migration of any animal in the world?
Bald eagle
Arctic tern
Sandpiper
Pacific gull
Each year, arctic terns travel between their breeding grounds in the Arctic Circle and their feeding grounds in the Antarctic Circle. If the terns flew in a straight line, the trip would be more than 18,000 miles. But the birds prefer to zig-zag across the Atlantic Ocean, stopping on each side and feeding on fish in between, totaling more than 44,000 miles traveled each year.
The correct answer to this quiz is Arctic tern.
