A Laysan albatross called Wisdom is a living wonder: She is the world's oldest known breeding bird in the wild, and still enjoys good health and is even still reproducing. Even scientists were left stunned by this unprecedented occurrence, especially considering that the lifespan of this species is usually around 50 years.
Laysan albatrosses only lay one egg per year, with both parents taking turns to incubate it. Throughout her long life, Wisdom has raised some 30-35 chicks, as estimated by experts. The bird has outlived several mates and traveled a whopping three to five million kilometers since 1956 when she was first tagged by USFWS biologist Chandler Robbins.
