Wisdom the 64-year old Laysan albatross is sighted on Midway Atoll National Wildlife Refuge

摘要

Wisdom was first banded in 1956. And because Laysan albatross do not return to breed until they are at least five years old, it is estimated Wisdom is at least 64 years old, but she could be older. Many birds lose their bands before they can be replaced. Wisdom's bands, however, were continuously replaced and because of meticulous record keeping associated with bird banding, we can verify she is the same bird first banded by noted author and Service ornithologist, Chandler Robbins. Biologists may find even older birds as old worn bands continue to be routinely replaced.
