The world's oldest known living wild bird at age 62 gave birth to a healthy
chick that hatched Sunday, challenging the conventional wisdom about how
long birds remain fertile.

This bird, named Wisdom by scientists who stuck a tag on her ankle years
ago, has lived longer than the average Laysan albatross, which 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

Wisdom, which hatched the chick at the Midway Atoll National Wildlife Refuge
in the Pacific Ocean, has raised chicks five times since 2006, and as many
as 35 in her lifetime.

Just as astonishing, she has likely flown as many as 3 million miles since
she was first tagged at the 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 (USGS).
