The world’s oldest known wild seabird has laid another egg.
U.S. Fish and Wildlife Service says the Laysan albatross named Wisdom appeared at her nest site at Midway Atoll National Wildlife refuge last month.
The Honolulu Star-Advertiser reports biologists confirm she laid the egg.
Wisdom and her mate return to the same site on Midway Atoll each year. Laysan albatrosses lay one egg and raise one chick per year.
Biologists believe Wisdom is at least 68 years old.

Biologists spotted the Laysan albatross called Wisdom at Midway Atoll National Wildlife Refuge earlier this month after she returned to the island to nest. She was incubating an egg at the same nest she uses each year with her mate. She's believed to be 66 years old. She's also the world's oldest known breeding bird in the wild.

Biologist Chandler Robbins first identified and banded Wisdom in 1956.
She has returned to Midway almost every year since 2002.
Midway Atoll is home to the world’s largest colony of albatross.
The island about 1,200 miles (1,930 kilometers) northwest of Honolulu was the site of a pivotal World War II battle.
