Southern Royal Albatross
Diomedea epomophora
The southern royal albatross has a length of 112 to 123 cm (44–48 in) and a mean weight of 8.5 kg (19 lb). At Campbell Island, 11 males were found to have a mean mass of 10.3 kg (23 lb) and 7 females were found to have a mean mass of 7.7 kg (17 lb), thus may be heavier on average than most colonies of wandering albatross. Males are about 2 to 3 kg (4.4 to 6.6 lb) heavier than females. Average wingspan has been reported from 2.9 to 3.28 m (9.5 to 10.8 ft), with an upper limit of about 3.50 m (11.5 ft).
