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 […]
Levy flight search patterns of wandering albatrosses
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 […]
Vocal Behavior of Swinhoe’s Storm-Petrel (Oceanodroma rnonorhis)
Swinhoes Storm-petrel (Oceanodroma monorhis) Science Article 1 abstract Swinhoe’s Storm-Petrel (Oceanodromma onorhis)is a nocturnal seabird related closely to Leach’s Storm-Petrel (Oceanodromale ucorhoa).S winhoe’s Storm-Petrel breeds in the northwestern Pacific Ocean on small islands around the Japan Sea or off Korea (Palmer1962, Cramp and Simmons 1977, Won and Lee 1986) MIKI TAOKA et al, Auk, Vol. […]
NORTH ATLANTIC POSSIBLE, PROBABLE AND REJECTED RECORDS OFSWINHOE’S STORM-PETREL AND EXTRALIMITAL BULWER’S PETREL
Swinhoes Storm-petrel (Oceanodroma monorhis) Science Article 2 abstract Records of Swinhoe’s Storm-petrel and extralimital records of Bulwer’s Petrel were researchedand are presented in the article
THE PELAGIC ECOLOGY OF MANX SHEARWATERS PUFFINUS PUFFINUSOFF THE SOUTHEASTERN UNITED STATES OF AMERICA
Manx Shearwater (Puffinus puffinus) Science Article 1 abstract Knowledge of the biology of Manx Shearwaters Puffinus puffinus is largely based on dataobtained in and around breeding colonies. In this paper I provide information on various aspects of the marine ecology of this shearwater. The information presented here on age and sex ratios, masses, moult sequence […]
Influence of migratory behaviour on the morphology and breeding biology of Puffinus Shearwaters
Little Shearwater (Puffinus assimilis) Science Article 1 abstract Ecological, life-history, breeding biology and morphologic data were collected for 18 shearwater species Puffinus spp., and the relationships between these parameters and migratory behaviour were investigated. Intraspecific variation in relative wing length was associated with differences in migratory behaviour of the Little Shearwater Puffinus assimilis populations, but […]

Obstruction and starvation associated with plastic ingestion in a Northern Gannet Morus bassanus and a Greater Shearwater Puffinus gravis
Greater Shearwater (Puffinus gravis) Science Article 1 abstract Plastic ingestion by seabirds is well documented (see Laist 1997for a list of species with ingestion records). However, casesdefinitively attributing seabird mortality to ingestion of plastic arerare. Seabirds that die from ingestion often suffer obstruction of thegastrointestinal tract. Ultimately, the birds die of starvation andoften quickly sink […]
