After courtship, the eagles find a branch on which to mate. The male eagles mounts the female from behind, straddling her back. Since male eagles do not have a penis, he delivers his sperm to her trough a clocal kiss. When the male has mounted the female, he will rub his cloca against the female's, flapping his wings and moving from side to side. Then, sperm will travel from the male's testicles into the female's clocal opening. He will then dismount her and soon, eaglets will be born.
