The world's oldest known bird just hatched a new chick. Wisdom, a Laysan albatross, returns to nest each year at Midway Atoll National Wildlife Refuge in Hawaii. When she was first tagged by scientists in 1956, she was estimated to be at least five years old, which would make her at least 65 today.

The new chick is named KÅ«kini, Hawaiian for messenger." "
