Grey-headed albatrosses normally breed every two years; if a chick is successfully reared the parents will not breed the following year. The nest is made of a cone of mud lined with grasses and all albatrosses lay only one egg. The egg is laid in mid-October and hatches during December. The male performs almost all of the incubation, which he carries out for the first 70 days. The chick takes three to four days to chip out of the egg and is then guarded for approximately three weeks. Most young depart from their natal nest the following May. The youngest recorded breeding bird was seven, and these birds can live to at least 36 years old (3).
This albatross feeds while on the sea surface and, even during breeding seasons when restricted by parental duties, undertakes marathon feeding trips, travelling up to 13,000 km on a single feeding flight (3) (6). The diet consists of fish, squid and crustaceans; although young seem to be fed mainly lampreys by their parents (3).
