The world's oldest known wild bird just added a new chick to the family — her 40th one, experts say.
The Laysan albatross (Phoebastria immutabilis), named Wisdom, is at least 65 years old but shows no signs of slowing down. Wildlife officials at the Midway Atoll National Wildlife Refuge in
saw her lay an egg on Nov. 28, 2015, and incubate it for several weeks. Hawaii
A fuzzy, gray chick cracked out of its shell on Feb. 1. But Wisdom wasn't there when the baby chick hatched: She had headed out to sea on Jan. 20, leaving her mate on nest duty. She returned just after Super Bowl Sunday (Feb. 7) with a full belly and settled down on the nest, allowing her mate to fly off to sea in search of food, officials said.
