The waved albatross, though, makes no nest and even moves its egg around the pair's territory, as much as 50 m (160 ft), sometimes causing it to lose the egg. [42] 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 nests are built on areas of lava with boulders and sparse vegetation, or thick brush. [9] The courtship of the waved albatross is a very elusive and spectacular sight. It includes: rapid bill circling and bowing, beak clacking, and an upraised bill to make a whoo hoo sound. The eggs are laid between April and June and incubated for two months.

The black-footed albatross, along with the Laysan albatross and the rare short-tailed albatross, are the three species of albatross that range in the northern hemisphere, as opposed to the rest of the family which range from the Equator south. There are at least 12 known breeding locations, but 97.5% of the total population is found colonially ...
The black-browed albatross is a medium-sized albatross, at 80 to 95 cm (31–37 in) long with a 200 to 240 cm (79–94 in) wingspan and an average weight of 2.9 to 4.7 kg (6.4–10.4 lb). [ 3 ] It can have a natural lifespan of over 70 years. It has a dark grey saddle and upperwings that contrast with the white rump, and underparts.
The northern royal albatross is typically about 115 cm (45 in), [8] weighs 6.2 to 8.2 kg (14–18 lb), and has a wingspan from 270 to 305 cm (106–120 in). [3][9] The juvenile has a white head, neck, upper mantle, rump, and underparts. There is dark speckling on the crown and rump. Its lower mantle and back are white with more black speckling ...
Light-mantled albatross, head detail Reproduction. The two species, like most seabirds, are colonial, although they are less colonial than the other species of albatrosses. In fact, on some breeding islands (like Tristan da Cunha) they may nest in very small groups or clusters of two to five nests, and the light-mantled will even nest singly ...
The short-tailed albatross usually first breeds at 10 years of age. [22] The short-tailed albatross lays a clutch of one egg that is dirty white, with red spots, mainly at the blunt end of the egg. It usually measures 116 by 74 millimetres (4.6 in × 2.9 in). The egg is incubated for around 65 days. Both sexes incubate the eggs. [22]
