When I'm sixty-four: world's oldest tracked bird returns to refuge with mate

Wisdom, a Laysan albatross, was spotted at mating ground on Midway Atoll after a year's absence and is expected to grow her brood, estimated at 36 chicks

The world's oldest living tracked bird has returned to US soil to lay an egg at the sprightly age of 64.

Wisdom, a Laysan albatross, was spotted at the Midway Atoll national wildlife refuge with a mate, following a year's absence. It's expected that Wisdom will use the world's largest nesting albatross colony, located north-west of Hawaii in the Pacific Ocean, to raise another chick.
