Bald eagles

They are the national emblem of the United States, and when it comes to maintaining relationships, bald eagles soar much higher than the country they symbolize. Bald eagles typically mate for life, except in the event of their partner's death or impotency — a number far lower than America's divorce rate, which now exceeds 50 percent.

"Bald eagles stay hitched until death do they part, often returning year after year to the same nest," Carolyn Shea wrote in Audubon. "While there, the pair continuously adds to the structure, so that after many seasons it assumes gargantuan proportions and stands as a symbol of their fidelity."
