From this story on Discovery News:
_John Klavitter of the U.S. Fish and Wildlife Service identified Wisdom with a new chick during a survey of the Midway Atoll National Wildlife Refuge where he is deputy manager. This is Wisdom's fourth year in a row of nesting, demonstrating her superior parenting skills. Many albatross take a year off in between their parenting duties. Wisdom's last vacation from motherhood was in 2007.
_Albatross mate for life and brood only one egg a year, spending another year at least raising the chick until it is fully fledged. For 3 to 5 years the young albatross will then excursion out to sea feeding on fish and squid, never touching land, and even taking naps in mid-flight. When they return to their breeding grounds the mating ritual can take several years, which is why Wisdom is expected to be in her mid-sixties and now a mother of what's likely a whole flock: Biologist Chandler Robbins of the U.S. Geological Survey first found Wisdom incubating an egg in 1956. Wisdom's partner has remained a mystery.
