The Laysan albatross thought to be the oldest breeding bird in the wild has just laid her latest egg, at a wildlife refuge on Midway Atoll.
The bird, named Wisdom, has been coming back to the refuge for more than 60 years and was first tagged in 1956.
Albatross take at least five years to reach sexual maturity after birth, which means she's at least 66 years old, biologists at the refuge say.
And not only do they return to the place they were born, despite spending most of their life travelling, but they usually use the same nesting site each year.

In the last 10 years Wisdom has fledged at least nine chicks, her latest hatching in February this year, according to the US Fish and Wildlife Service (USFWS).
The egg was spotted earlier this month and the USFWS project leader for the refuge, Charlie Pelizza, says he could tell something was up when he went to lunch.
"The staff was abuzz with the news that Wisdom was back and incubating," he says.
"It's amazing what a bit of good news can do to brighten the day."
Wisdom will switch incubating the egg with her mate, Akeakamai, over the next few months until hopefully, it hatches.
