World’s Oldest Wild Bird Lays Egg at 74 in Hawaii
- 08 Dec 2024
In News:
Wisdom, the world’s oldest known wild bird, a Laysan albatross, has laid her estimated 60th egg at the age of 74. This remarkable event occurred at the Midway Atoll National Wildlife Refuge in the Pacific Ocean, part of the Hawaiian Archipelago.
Background on Wisdom and Laysan Albatrosses
Wisdom, first banded as an adult in 1956, has been a part of the albatross population in the Pacific for decades. Laysan albatrosses are known for their strong migratory habits and lifelong pair bonding.
The Life Cycle of the Laysan Albatross
The egg incubation process for Laysan albatrosses is shared between both parents and lasts around seven months. Once the chick hatches, it takes five to six months to develop before it is ready to take its first flight over the ocean. These seabirds, which predominantly feed on squid and fish eggs, spend the majority of their lives soaring across the open seas.
Wisdom’s longevity and success in raising up to 30 chicks over her lifetime have been notable achievements. While Laysan albatrosses typically live up to 68 years, Wisdom’s age surpasses this average by several years.
About the Laysan Albatross
The Laysan albatross (Phoebastriaimmutabilis) is a large seabird found across the North Pacific. The Northwestern Hawaiian Islands host nearly the entire population of Laysan albatrosses, with most breeding pairs found on islands like Laysan and Midway Atoll. These birds are known for their long-distance soaring capabilities, with some covering hundreds of miles a day without flapping their wings.
Laysan albatrosses have blackish-brown upper wings and backs, with flashes of white in their primary feathers. They are monogamous, forming lifelong bonds with a single mate. Despite their impressive flying ability and vast range, their population is currently listed as "Near Threatened" by the International Union for Conservation of Nature (IUCN).
