Wandering Albatross (Diomedea exulans) Science Article 15 abstract The foraging activity of wandering albatrosses Diomedea exulans was studied with simultaneous use of satellite transmitters, activity recorders and loggers measuring the timing of feeding. On average birds spent 60% of their foraging time in flight, mostly during the day, and 40% on the water, mainly at […]

POTENTIAL INTERACTIONS BETWEEN WANDERING ALBATROSSES AND LONGLINE FISHERIES FOR PATAGONIAN TOOTHFISH AT SOUTH GEORGIA
Wandering Albatross (Diomedea exulans) Science Article 10 abstract We examine the extent of overlap between South Georgia wandering albatrosses(Diomedea exulans) and local longline fishing for Patagonian toothfish (Dissostichuseleginoides), using satellite-tracking data and precise haul locations, respectively. Weconclude that D. exulans breeding at South Georgia have a relatively low potential riskof interaction with longline fisheries around […]
Heart rate and energy expenditure of incubating wandering albatrosses: basallevels, natural variation, and the effects of human disturbance
Wandering Albatross (Diomedea exulans) Science Article 13 abstract We studied the changes in heart rate (HR) associated with metabolic rate of incubating and resting adult wandering albatrosses (Diomedea exulans) on the Crozet Islands. Metabolic rates of resting albatrosses fitted with external HR recorders were measured in a metabolicchamber to calibrate the relationship between HR and […]
Population changes and biology of the wandering albatross Diomedea exulans gibsoni at the Auckland Islands
Wandering Albatross (Diomedea exulans) Science Article 6 abstract Gibson’s wandering albatross Diomedea exulans gibsoni is endemic to the Auckland Islands in the New Zealand subantarctic. In 1991 a programme of regular census and population study was initiated to assess the impact of longline fisheries bycatch on the status of the subspecies. This paper reports on […]
Global population structure and taxonomy of the wanderingalbatross species complex
Wandering Albatross (Diomedea exulans) Science Article 11 abstract A recent taxonomic revision of wandering albatross elevated each of the four subspecies tospecies. We used mitochondrial DNA and nine microsatellite markers to study the phylogeneticrelationships of three species (Diomedea antipodensis,D. exulansandD. gibsoni) in thewandering albatross complex. A small number of samples from a fourth species,D. dabbenena,were […]
Evidence for olfactory search in wandering albatross,Diomedea exulans
Wandering Albatross (Diomedea exulans) Science Article 2 abstract Wandering albatrosses (Diomedea exulans) forage over thousands of square kilometers of open ocean for patchily distributed live prey and carrion. These birds have large olfactory bulbs and respond to fishy-scented odors in at-sea trials, suggesting that olfaction plays a role in natural foraging behavior. With the advent […]
Orientation in the wandering albatross: interfering with magnetic perception does not affect orientation performance
Wandering Albatross (Diomedea exulans) Science Article 16 abstract After making foraging flights of several thousands of kilometres, wandering albatrosses (Diomedea exulans) are able to pinpoint a specific remote island where their nests are located. This impressive navigation ability is highly precise but its nature is mysterious. Here we examined whether albatrosses rely on the perception […]
Trails of the Wandering Albatross Applying the mathematics of haphazard motion
Wandering Albatross (Diomedea exulans) Science Article 14 abstract The wandering albatross flies extraordinary distances. Riding the wind on long, thin, rigidlyoutstretched wings, it skims the waves as it glides for hours over the ocean surface.Truly a world traveler, this seabird (Diomedea exulans) regularly circles the globe at southernlatitudes, plunging into the sea to scoop up […]
Functional significance of sexual dimorphism in Wandering Albatrosses, Diomedea exulans
Wandering Albatross (Diomedea exulans) Science Article 9 abstract 1.The investigation covered whether sexual dimorphism could affect flight performancein a manner that is consistent with differences in at-sea distribution of male and femaleWandering Albatrosses, Diomedea exulans Linnaeus. Adult morphology was also comparedto near-fledged chicks to assess whether morphological differences are consistent with different at-sea distributions of […]
COURTSHIP BEHAVIOUR OF THE WANDERING ALBATROSSDIOMEDEA EXULANS AT BIRD ISLAND, SOUTH GEORGIA
Wandering Albatross (Diomedea exulans) Science Article 1 abstract The behaviour postures and their sequences during courtship displays of the Wandering Albatross Diomedea exulansat South Georgia are described. Females initiated most display bouts, which began with a series of greetings. Thecore of the display consisted of a rapid sequence of head movements, snaps, ritualized preening and […]
