All the albatrosses in the south live in large nests. They make it with grass, soil, and sometimes penguin feathers. The Waved Albatross, however, does not make a nest but instead moves its egg around the pair’s territory, as much as 50 m (160 ft). This may sometimes make it lose the egg. In all albatross species, both parents incubate the egg from between one day and three weeks. Incubation lasts around 70 to 80 days. This time may become more longer for the larger albatrosses. When they do this, it takes a lot of energy, and the adult can lose as much as 83 g (2.9 oz) of body weight a day.
