The sun loving Arctic tern makes the longest possible migration –

from the top of the world to the bottom and back.

Each year its round trip is ~ 22,000 miles (32,000 k.m.)

It lives its entire life where the day is the longest.

It breeds in the unbroken daylight of the Arctic summer.

It flies back with the sun to feed in the nearly endless day of the Antarctic Summer.

It can cover more than 100 miles (160k.m) a day on an average.
