Wisdom, the Laysan albatross (or mōlī in Hawaiian), Phoebastria immutabilis, has once again returned to Midway Atoll National Wildlife Refuge to nest. She was originally banded as she incubated an egg on 10 December 1956 by legendary bird biologist and USGS scientist Chandler Robbins. Since Laysan albatross don’t nest until they are at least 6 years old and may not successfully raise a chick until they are between the ages of 8 to 10 years, Wisdom is estimated to be at least 75 years old. This makes her the world’s oldest known wild bird. In her lifetime, scientists estimate that Wisdom has flown more than 3 million miles, laid 50–60 eggs, and fledged some 30 chicks…”
