Many birds are monogamous, but Laysan Albatrosses mate for life. Young birds search for a mate with elaborate courtship dances. Once they hit breeding age, Albatrosses breed their entire lives, hatching and caring for one chick at least every other year. Pictured here is Wisdom — the oldest living, banded, wild bird — and her current mate at their nest at Midway Atoll National Wildlife Refuge.
