Wisdom, the world’s oldest known wild bird, is preparing to be a mother again after laying an egg at the ripe age of 63.
The Laysan albatross also had an egg hatch in February, meaning the latest arrival will be her 36th chick, according to estimates.
Wisdom laid the egg at a nesting site at the Midway Atoll National Wildlife Refuge in the North Pacific, about 1,200 miles (1,930 km) northwest of Honolulu, Hawaii.
Laysan albatrosses are monogamous, meaning they mate for life with just one partner, making it all the more remarkable that she has consistently been laying eggs over the past three decades.
She is said to have had the same partner throughout her life, although experts can't know for certain without running tests on the offspring.
