America's oldest known wild bird is a new mother.
Wisdom, a Laysan albatross in her 60's, has a new chick, according to the US Geological Survey.
She was spotted a few weeks ago with a chick at the Midway Atoll National Wildlife Refuge in the North Pacific Ocean, the U.S. Fish and Wildlife Service (FWS) announced on March 8.
Wisdom Is At Least 60 Years Old
Wisdom was first banded in 1956 as she incubated an egg, and she was estimated to be at least 5 years old then. This is the earliest age at which these birds breed, though they more typically breed at 8 or 9 after an involved courtship lasting several years. She has since worn out five bird bands.
