This is a good question:). Imagine, they are sometimes looking for a couple for 15 years! They nest on the shores of the Southern Ocean on the rocks. They have long mating dances with shouts and bows. They choose rocks not by chance, it is easier to take off there. But they never land on ships, it is difficult for them to take off.
Apparently, albatrosses need land only to prolong their kind in heavenly wanderings:)
