The world’s oldest known wild bird has laid an egg at the approximate age of 74, US biologists say.

Wisdom, a Laysan albatross, was filmed by the US Fish and Wildlife Service (USFWS) at the Midway Atoll national wildlife refuge in the Pacific Ocean with her latest partner looking after the egg.

Members of the species usually only live for 12-40 years, but Wisdom was tagged in 1956 when she was about five.
