The deployment of capillary depth recorders, which record the maximum dive depth undertaken by a bird, has shown that while some species, such as the wandering albatross, do not dive deeper than a metre, some species, such as the light-mantled albatross, have a mean diving depth of almost 5 m (16 ft) and can dive as deep as 12.5 m (41 ft).

Together with the Amsterdam albatross, it forms the wandering albatross species complex, which some began referring to more recently as "snowy" [3]. The snowy albatross is one of the two largest members of the genus Diomedea (the great albatrosses), being similar in size to the southern royal albatross. It has the greatest known wingspan of any ...
The snowy albatross and the southern royal albatross are the largest of the albatrosses and are among the largest of flying birds. They have the largest wingspans of any bird, being up to 3.5 m (11 ft) from tip to tip, although the average is a little over 3 m (9.8 ft).
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.
The northern royal albatross or toroa, [3] (Diomedea sanfordi) is a large seabird in the albatross family. It was split from the closely related southern royal albatross as recently as 1998, though not all scientists support that conclusion and some consider both of them to be subspecies of the royal albatross .
Though they look clumsy on land, when they take to the air they are elegant and strong fliers. ... The Galapagos albatross is critically endangered with a declining population. Today, there are ...
The Amsterdam albatross or Amsterdam Island albatross, [2] (Diomedea amsterdamensis), is a large albatross which breeds only on Amsterdam Island in the southern Indian Ocean. It was only described in 1983, and was thought by some researchers to be a subspecies of the wandering albatross, D. exulans (now the snowy albatross ).
The southern royal albatross has a length of 112 to 123 cm (44–48 in) [13] 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.
