Forget about the stork — it's the albatross that should be in charge of baby delivery. That's because the world's oldest wild breeding bird mother, a 66-year-old albatross named Wisdom, is incubating another egg, likely her 41st one, experts say.
Wisdom's new chick is unexpected; many albatrosses don't breed for two consecutive years, and Wisdom had a chick last year. Rather, most lay an egg one year and then take a break the next, instead investing their time and energy into molting their feathers, said researchers at the Midway Atoll National Wildlife Refuge and Battle of Midway National Memorial, located about 1,400 miles (2,250 kilometers) northwest of Hawaii.
Having healthy feathers is important because albatrosses spend almost 90 percent of their time flying, often covering thousands of miles as they search for food in the north Pacific Ocean, the researchers said.
