The world’s oldest known bird is set to become a mother again – after raising at least 30 other youngsters.
An albatross called Wisdom has laid another egg at her nest site in a wildlife refuge on a tiny island about 2,000km northwest of Hawaii.
Biologists believe Wisdom is at least 68 years old, forcing them to re-evaluate the age which they expected albatrosses to live to.
Albatross mate for life, but will recouple if a partner dies.
Albatross lay a single egg and incubate it for just over two months before they spend another five months rearing it to fledgling status after it hatches.
During that time, Wisdom and her partner will take it in turns to sit on the egg or tend to the chick as the other searches for food at sea.
