'World's oldest seabird' expecting - again

The world's oldest known seabird is expecting - again.

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.

The US Fish and Wildlife Service's project leader for the refuge, Bob Peyton, said in a statement on Friday that Wisdom has been returning to Midway for more than six decades.

An ornithologist first put an identification band on her in 1956. She's had a few dozen chicks.

Midway is an atoll in the North Pacific Ocean about 1930km northwest of Honolulu. It's part of the Papahanaumokuakea Marine National Monument.
