The Sooty shearwater (No: Grålire) seabird has been known to fly long distances over the oceans looking for food and migrating with the seasons. How far they flew was unknown until a group of scientists tagged the birds with satellite location devices.
This shows 19 birds during 262 days of breeding and migration. Wild!
The birds are very common, and also live in the Atlantic where they migrate from the Falklands to Jan Mayen.
