Yelkouan Shearwater (Puffinus yelkouan) Science Article 2 abstract Over the past six months, the EU LIFE Yelkouan Shearwater Project has been undertaking fieldwork to fitelectronic devices to the Yelkouan Shearwaters to monitor their movements at sea. The tags are the latest intechnology for seabird tracking. This is the first time that such extensive research on […]

WAX DIGESTION IN WILSON’S STORM-PETREL
Wilsons Storm-petrel (Oceanites oceanicus) Science Article 4 abstract Captive Wilsons’ storm-petrels (Oceanites oceanicus) fed a diet of pure wax (hexadecyl oleate) or triacylglycerol (olive oil) increased in body mass or lost mass moreslowly than birds given only water, depending upon the quantity of lipid they were fed. BRYAN S. OBST, Wilson Bull., 98(2), 1986, pp. […]
aeRODYNAMICS AND HYDRODYNAMICS OF THE ‘HOVERING’ FLIGHT OF WILSON’S STORM PETREL
Wilsons Storm-petrel (Oceanites oceanicus) Science Article 5 abstract Wilson’s storm petrel (Oceanites oceanicus) characteristically feeds by’ hovering’ over the water surface, but its technique for this is unlike that ofother flying vertebrates. The kinematics and aerodynamics of this ‘ hovering’flight were investigated to determine the possible sources of lift PHILIP C. WITHERS, J. exp. Biol. […]
NIDIFICACION y HABITAT DEL PETREL DE WILSON (OCEANITES OCEANICUS) EN PUNTA CIERVA, COSTA DE DANCO, PENINSULA ANTARTICA
Wilsons Storm-petrel (Oceanites oceanicus) Science Article 1 abstract Studies on Wilson’s Storm-Petrel population at Cierva Point, Danco Coast, Antarctic Peninsula (64 09 S, 60 57 W), were done in the austral summer 1994-1995. The research was carried out in two areas, along the rocky coast and in the moss-covered hillsides. Jose Luis Orgeira, ORNITOLOGIA NEOTROPICAL […]
The food demand in the nest of Wilson’s storm petrel
Wilsons Storm-petrel (Oceanites oceanicus) Science Article 3 abstract Energy delivered to the nests of Wilson’s storm petrel, Oceanites oceanicus(Kuhl, 1820), was evaluated by measurement of the oxygen consumption of brooding adultbirds and nestlings of different ages.

Olfactory foraging strategies of procellariiform seabirds
White-faced Storm-petrel (Pelagodroma marina) Science Article 1 abstract The study of olfactory foraging ability in procellariiform seabirds is now beginning to explore how species aremorphologically and behaviorally adapted to track odor plumes, and to relate these findings to models of odor transport innatural situations. According to the models, odors in atmospheric flow tend to be […]
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 […]
Extra-pair paternity in the strongly monogamousWandering AlbatrossDiomedea exulanshas noapparent benefits for females
Wandering Albatross (Diomedea exulans) Science Article 17 abstract Although 92% of avian species are socially monogamous, extra-pair copulation (EPC),resulting in extra-pair paternity (EPP), is a common reproductive strategy in birds. Amongseabirds, in which the rate of social monogamy reaches 100%, Procellariiformes (albatrossesand petrels) show low EPP rates, with the noticeable exception of the only albatross […]
