Arctic tern makes longest ever migration – equal to flying twice around the planet

A tiny bird from the Farne Islands off Northumberland has clocked up the longest migration ever recorded. The Arctic tern’s meandering journey to Antarctica and back saw it clock up 59,650 miles, more than twice the circumference of the planet.

Its mammoth trek was recorded by a tiny device attached to its leg, weighing 0.7g - too light to affect its flight.
