Albatross named Wisdom astounds scientists by producing chick at age 62
By Darryl Fears, Tuesday, February 5, 7:34 PM
She is described as awesome. And wonderful. And maybe a little weird. She is the world’s oldest known living wild bird at age 62, and she produced a healthy chick that hatched Sunday.
It’s pretty amazing that Wisdom, named by scientists who stuck a tag on her ankle years ago, has lived this long. The average Laysan albatross dies at less than half her age. Scientists thought that, like other birds, albatross females became infertile late in life and carried on without producing chicks.
But Wisdom, who hatched the chick at the Midway Atoll National Wildlife Refuge in the Pacific Ocean, defies comparison. Her feat could prompt scientists to chuck some of their early theories about the bird out the door.
Wisdom has raised chicks five times since 2006, and as many as 35 in her lifetime. Just as astonishing, she has likely flown up to 3 million miles since she was first tagged at Midway Atoll at the end of the Hawaiian Island chain in 1956, according to scientists who have tracked her at the U.S. Geological Survey. That’s “4 to 6 trips from the Earth to the Moon and back again with plenty of miles to spare,” the USGS said in an enthusiastic announcement Tuesday.
