According to the U.S. Fish and Wildlife Service, ‘Wisdom’ a Laysan albatross (Phoebastria immutablis) laid her 60th egg at the Midway Atoll National Wildlife Refuge. Her history is well documented having been banded as n mature bird at the refuge. It is estimated that she has flown 3 million miles in her life and outlived her first mate.
The longevity and prolonged egg production should serve as an inspiration for geneticists who are striving for a 100-week production cycle for domestic hens.
