Worlds oldest known seabird lays an egg at age of 66

Laysan albatross known as Wisdom is also the worlds oldest known breeding bird in the wild and has had a few dozen chicks

The worlds 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. Shes believed to be 66 years old. Shes also the worlds oldest known breeding bird in the wild.

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

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

Midway is about 1,900km (1,200 miles) northwest of Honolulu. Its part of the Papahanaumokuakea marine national monument.
