In all albatross species, both parents incubate the egg in stints that last between one day and three weeks. Incubation lasts around 70 to 80 days (longer for the larger albatrosses), the longest incubation period of any bird. It can be an energetically demanding process, with the adult losing as much as 83 g (2.9 oz) of body weight a day. [43]

Waved albatross are spectacular flyers, perhaps even the most famous. They can fly for hours without stalling and they do this by dynamic soaring. The wind speed near the surface of the sea is much lower than about 50 ft (15 m) in the air. The waved albatross uses this to its advantage by gliding at speed into the wind.
