Bird is mom again, at 60

The oldest known wild bird in the U.S. is a new mother.

Wisdom, a Laysan albatross, is at least 60 years old. As part of the North American Bird Banding Program, a U.S. Geological Survey scientist first banded Wisdom as she incubated an egg in 1956. She was estimated to be at least 5 years old at the time. The albatross has since worn out five bird bands.
