The northern royal albatross usually pairs for life, with new pairs performing elaborate courtship displays that include actions like ‘bill-circling’, ‘sky-pointing’, ‘flank-touching’ with the bill, and full spreading of the wings, typically accompanied by a variety of calls. Breeding occurs every two years if successful (6). Previously mated pairs usually use the same nest site from season to season (7), and usually return to their breeding grounds between mid-October and mid-November, with the female laying her single egg a month later (6). After 79 days incubation the hatchling emerges, and the young fledges 240 days later from September to October the following year. These long-lived birds return to their natal colony at four to eight years of age but do not start to breed until at least nine years, and have been recorded to live up to at least 61 years in the wild (6).
The northern royal albatross feeds mainly on fish and squid, supplemented by crustaceans and carrion (2).
