Laura Erickson's For the Birds

This exquisite bird no longer lives up to its name over much of its range, but it’s still fairly easy to see in range. It’s surprisingly long-lived. The oldest recorded Common Tern was at least 28 years, 11 months old, when it was recaptured and rereleased during banding operations in Massachusetts in 2005; the same state where it was banded in 1976. It also holds a place in the Guinness Book of World Records:

Common Tern: Greatest distance flown by a bird. The greatest distance covered by a ringed bird is 26,000 km (16,250 miles) by a common tern (Sterna hirundo) banded as a juvenile on 30 June 1996 in central Finland. It was recaptured alive at Rotamah Island, Victoria, Australia in the fourth week of January 1997. To have reached this destination it is believed the bird had to have travelled 200 km (124 miles) per day.

Individual Arctic Terns have almost definitely flown further, but we would need to band one on its summer range and then luck into recapturing that exact same bird on its winter range (or vice versa).
