HONOLULU -- 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 is the world's oldest known breeding bird in the wild. An ornithologist first put an identification band on her in 1956. She's had a few dozen chicks.
