Although albatrosses are paradigms of oceanic specialization, their foraging areas and migration routes when not breeding remain essentially unknown. Our continuous remote tracking of 22 adult gray-headed albatrosses for over 30 bird-years reveals three distinct strategies: (i) Stay in breeding home range; (ii) make return migrations to a specific area of the southwest Indian Ocean; and (iii) make one or more global circumnavigations (the fastest in just 46 days). The consistencies in patterns… 

Foraging ecology of albatrosses and petrels from South Georgia: two decades of insights from tracking technologies

Improved coverage of different life-history stages and seasons has revealed striking variation in distribution in relation to seasonality of resources and reproductive constraints, and more detailed analyses of activity patterns suggest that birds adjust flight behaviour at multiple spatial scales.

Tracking Long-Distance Songbird Migration by Using Geolocators

Migration routes of migratory songbirds to the Neotropics were mapped by using light-level geolocators mounted on breeding purple martins and wood thrushes and suggesting high connectivity of breeding and wintering populations.

Migratory tactics and wintering areas of Northern Gannets (Morus bassanus) breeding in North America

Migration has evolved to allow organisms to undertake life-history functions in the most appropriate place at the most appropriate time. Migration creates seasonal ecological linkages that have

Stage-dependent distribution of the Critically Endangered Amsterdam albatross in relation to Economic Exclusive Zones

From the areas visited by the albatrosses, which coastal states share responsibility in regulating industrial fishing in their Exclusive Economic Zones (EEZs) are identified, to promote the preservation of this species.


Many birds show a surprising degree of intraspecific variability in migratory tendency and choice of wintering site. In this study, we tracked the seasonal movements of 35 nonbreeding Black-browed

Tracking of Arctic terns Sterna paradisaea reveals longest animal migration

The tracking of 11 Arctic terns fitted with miniature (1.4-g) geolocators revealed that these birds do indeed travel huge distances, and identified a previously unknown oceanic stopover area in the North Atlantic used by birds from at least two breeding populations.

Albatross overlap with fisheries in the Benguela Upwelling System: implications for conservation and management

Evidence is presented that black- browed albatrosses forage to a much greater extent on natural prey than do white-capped alba- trosses, and the benefit of a management decision to limit discarding as a mitigation measure is likely to outweigh the disadvan- tage of reduced food.

A comprehensive isotopic investigation of habitat preferences in nonbreeding albatrosses from the Southern Ocean

It is highlighted the overwhelming importance of subtropical waters for albatrosses, where the birds are known to interact with human activities and are more likely to be negatively affected by the diverse range of fi sheries operating in both neritic and oceanic waters.

Post-Fledging Dispersal of King Penguins (Aptenodytes patagonicus) from Two Breeding Sites in the South Atlantic

Most studies concerning the foraging ecology of marine vertebrates are limited to breeding adults, although other life history stages might comprise half the total population. For penguins, little is



Oceanic respite for wandering albatrosses

It is shown that during these periods wandering albatrosses leave the foraging grounds that they frequent while breeding for specific, individual oceanic sectors and spend the rest of the year there — each bird probably returns to the same area throughout its life.

Foraging niches of three Diomedea albatrosses

Three species of biennial breeding southern hemisphere albatrosses — Diomedea san- fordi from the Chatham Islands, D. antipodensis from Antipodes Island and D. exulans from South Georgia — were

Satellite Tracking of the Wandering Albatross Diomedea exulans around Australia and in the Indian Ocean

The flight paths of five Wandering Albatrosses Diomedea exulans chionoptera were followed using satellite telemetry from Bellambi, New South Wales, around southern Australia to off Cape Leeuwin, Western Australia, and across the Indian Ocean.

Foraging distribution of the black-browed albatross, Thalassarche melanophris, breeding in the Falkland Islands

1.The overall foraging distribution of black-browed albatross from the Falkland Islands is described, based on data from two different stages of the breeding season and two separate breeding sites,

Accuracy of geolocation estimates for flying seabirds

The accuracy of GLS tags is more than adequate for tracking migration and breeding-season foraging ranges of pelagic species, and for identifying broad-scale habitat preferences, overlap and potential conflict with commercial fisheries.

Seasonal sexual segregation in two Thalassarche albatross species: competitive exclusion, reproductive role specialization or foraging niche divergence?

It is suggested that seasonal sexual segregation in black–browed and grey–headed albatrosses is attributable to niche divergence mediated by differences in flight performance, and may have implications for conservation in relation to sex–specific overlap with commercial fisheries.
