Not all couples show affection the same way. Clearly. Eagles mate for life, choosing the tops of large trees to build nests, which they typically use and enlarge each year. Nests may reach 10 feet across and weigh a half ton. Breeding bald eagles typically lay one to three eggs once a year. Learn more about bald eagles. Photo by Roy W. Lowe.

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. Photo by Pete Leary, USFWS.
