At 70 years of age, Wisdom the Laysan albatross has hatched another chick. Regarded as "oldest known wild bird in history", Wisdom has outlived previous mating partners as well as the biologist Chandler Robbins, who first banded her in 1956. Wisdom hatched the chick on 1 February in the Midway Atoll national wildlife refuge in the North Pacific, where more than a million albatross return to nest each year. Wisdom's long-term mate, Akeakamai, who she has been with since 2010 according to the US Fish & Wildlife Service (USFWS), fathered the chick. The USFWS also stated that albatross find their mates through "dance parties". "We believe Wisdom has had other mates," US Fish and Wildlife Service biologist Dr Beth Flint said. "Though albatross mate for life, they may find new partners if necessary " for example if they outlive their first mate." USFWS estimated Wisdom has hatched more than 30 chicks over the course of her lifetime. Sean Dooley, national public affairs manager for BirdLife Australia, was excited about the news of Wisdom's latest chick. "Because she only nests every two years, the international bird community looks forward to see if she's been able to come back and nest," Dooley said. "The odds are stacked against them so much, whenever it happens it's always a cause for celebration."
