The albatross relies on strong winds to fuel their flight, and it is supposed that the generally calm air in the tropics acts as a barrier to the easy northern passage of these birds.
Albatrosses mate for life, and can live to be fifty years of age or more, so those youngsters might just be enjoying the feel of the sea before returning to their colonies to assume adult roles.
The first albatross we saw was a fl-footed albatross, and it came soaring across the sea towards us from the vicinity of a fishing trawler.

 Black-footed albatross - Phoebastria nigripes: More Information - ARKive   (Site not responding. Last check: 2007-11-05)
Black-footed albatrosses are birds of the northern Pacific Ocean, ranging from the sub-Artic sea southwards beyond the Hawaiian Islands, west as far as the China Sea and east to the North American coast, extending as far south as Baja California (4).
Albatross chicks stay in the nest for a long time; six months in the case of the fl-footed, and it may wander away from the nest site when it reaches two or three months old (2).
The fl-footed, like many other albatrosses, is currently under threat from by-catch in the long-line fishing industry; as many as 2,000 birds a year are thought to be lost from fishing vessels operating out of the USA, and as many as 8,000 from Japanese fisheries.

The Black-footed Albatross (Diomedia nigripes) is one of two species of Albatross that nests annually in the Hawaiian Islands, and one of three that occur regularly in the North Pacific (the other species being Laysan and Short-tailed Albatrosses).
Black-footed Albatross arrive on the nesting grounds in November and adults depart in the late spring, with juveniles departing by late June.
Most Laysan Albatrosses manage to find their way back to the island on which they were born, with only a few birds travelling to other areas; these "lost" birds however, may be the colonisers of new breeding grounds, helping the species to spread to other island-chains.

 PFRP Protected Species Project - Diet dynamics of Laysan & Black-footed albatross populations
Because of their scavenging nature, the diet of these albatrosses may to some extent be dependant on fisheries such as drift-net and pelagic longline as a source of food.
It is possible that the decline of Laysan and Black-footed albatrosses may in part be due to changes in their trophic relations, namely, where on the food chain they feed.
It is anticipated that up to an additional 50 albatrosses from the breeding colonies and 100 albatrosses from the Hawaii longline fishery may be salvaged for research purposes.

 Band Loss in North Pacific Populations of Laysan Albatross (Diomedea immutabilis) and Black-footed Albatross (D. ...
Because most of the albatrosses were banded in the north Pacific colonies with conventional aluminum bands, it is essential to study their wear patterns if those data are to be used to model populations or generate life tables.
Because albatrosses are among the longest lived of all birds, their bands should be suited to their life span and extended breeding period.
For these two albatrosses which had large numbers banded with conventional aluminum tags during the 1960s and 1970s, it is now critical to reband these adults to retain at least part of the very old banded cohorts for future research.

 BREEDING CYCLES AND BEHAVIOR OF LAYSAN AND BLACK-FOOTED ALBATROSSES
The Laysan Albatross, to a greater degree than the Black-foot, uses the bill to rake sand, twigs, and leaves to the rim of the nest; this material is pressed down and compacted with the side of the bill.
Our observations of albatrosses and several petrels and shearwaters demon- strate beyond question that the oil serves primarily as a food for the chick, and is thus analogous to pigeon milk; in some species (but not in alba- trosses) it is secondarily utilized as a defense mechanism.
The markedly lower temperature of the incubating Laysan Albatrosses is perhaps due to the fact that their nests were built in the shade on moist organic soils, whereas the incubating Black-foots were in direct sunlight on dry coral sand.

Based on a comparative approach, Niel and Lebreton (2001) showed that suspected levels of bycatch for the fl-footed albatross were large enough to possibly affect population growth.
Furthermore, there are a number of peculiarities in the the demography of these birds which pose special problems for the parameter estimation and modeling, such as late age of maturity, low reproductive output, high adult survival rate, and long term pair bonding behavior.

The three Albatrosses described in this volume may very easily be distinguished by the form of the bill, independently of all other characters.
Diomedea nigripes has the bill much thicker, or less compressed than the other two species; its ridge very broad and convex at the base, its basal outline being semicircular and two inches in extent, so that its sides behind overlap and obliterate the sutural space behind the nostrils.

 PCBs, DDE, DDT, and TCDD-EQ in Two Species of Albatross on Sand Island, Midway Atoll, North Pacific Ocean - ...
The Laysan albatross diet consists primarily of ommastrephid squid (68% of the diet); the remainder of the diet consists of approximately 9% fish, 9% crustaceans, and 4% coelenterates [7].
In 1969, concentrations of PCBs and DDE in visceral fat of Laysan albatrosses were 22.3 mg/kg and 13.7 mg/kg, respectively; whereas visceral fat of fl-footed albatrosses contained a mean concentration of 15.3 (7.5-21.3) mg/kg and 15.3 (5.1-22.7) mg/kg of PCBs and DDE, respectively.
The HQ for fl-footed albatrosses was approximately 10, which, based on observations in populations of fish-eating birds of the North American Great Lakes, would be expected to be causing subtle population-level effects, such as embryo lethality [1,2] and deformities [14,27,28].
