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 […]

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 […]

Wandering Albatross (Diomedea exulans) Science Article 18 abstract LEVY flights are a special class of random walks whose step lengths are not constant but rather are chosen from aprobability distribution with a power-law tail. Realizations of Levy flights in physical phenomena are very diverse, examplesincluding fluid dynamics, dynamical systems, and micelles [1,2]. This diversity raises […]

Wandering Albatross (Diomedea exulans) Science Article 7 abstract Exchange of 61 wandering albatrosses Diomedea exulans has been recorded between the French Crozet Islandsand the South African Prince Edward Islands, 1 068 km apart in the Southern Ocean. Most movements of bandedbirds (57) have been westwards, from the Crozets to the Prince Edwards, In all, 18 […]

Wandering Albatross (Diomedea exulans) Science Article 8 abstract Many large marine vertebrates are today threatened by human activities and it istherefore crucial to obtain information on their distribution and behaviour at sea. Inparticular little is known about the time necessary for juveniles to acquire the foragingskills of adults. We tracked 13 juvenile wandering albatrosses Diomedea […]

Wandering Albatross (Diomedea exulans) Science Article 5 abstract Deployment of devices which record timing and magnitude of food ingestion in two wandering albatrosses Diornedea exulans at sub-Antarctic Marion Island shows that feeding occurred both at night and during the day, but with most ingestion events (70%) occurring during daylight hours. John COOPER, Rory P. WILSON […]

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 […]

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 […]

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 […]
