Wisdom, the world’s oldest known wild bird, has hatched another chick at Midway Atoll National Wildlife Refuge.
The Laysan albatross supermom is at least 68 years old, according to U.S. Fish and Wildlife Service officials, and has given birth to and raised at least 31 chicks in her lifetime.
Wildlife officials spotted Wisdom at her nest site at Midway on Nov. 29, where she soon laid an egg. The chick hatched at the beginning of the month, according to the Fish and Wildlife Service.
Laysan albatrosses mate for life and lay only one egg per year. Since 2006, Wisdom and her mate, Akeakamai, have returned to Midway Atoll at Papahanaumokuakea Marine National Monument to lay and hatch an egg.
After the egg is laid, the albatross parents spend about seven months incubating it. They take turns, with one incubating the egg while the other forages for food. After another five to six months, the chicks fledge, or fly out to sea, where they spend most of their lives soaring over the ocean and feeding on squid and fish eggs.
About 3 million seabirds nest at Midway Atoll, including about a million albatrosses, which return to where they were born each year to nest and raise their young, a behavior known as “nest-site fidelity,” according to the Fish and Wildlife Service. In 2017 one of the chicks that Wisdom gave birth to was observed just a few feet away, marking the first time a returning chick of hers had been documented.
“Midway Atoll’s habitat doesn’t just contain millions of birds, it contains countless generations and families of albatrosses,” said Kelly Goodale, Fish and Wildlife Service Refuge biologist, in an email. “If you can imagine when Wisdom returns home she is likely surrounded by what were once her chicks and potentially their chicks.”
Wisdom was first banded as an adult in 1956 by biologist Chandler Robbins, who was studying the colony at Midway.
