Blackcap (Sylvia atricapilla) Science Article 2 abstract To describe the phenology of migratory passages and wintering of Blackcaps.Location: Orange plantations in eastern Spain.Methods: Data were collected between 1997 and 2002 at a Constant Effort Site. Results: We captured between 94 and 206 individuals per season (from September to April of the next year). We used […]
Migratory fuelling in blackcaps [Sylvia atricapilla)under perceived risk of predation
Blackcap (Sylvia atricapilla) Science Article 8 abstract It has been argued that the body mass levels achieved by birds are determined by the trade-off be-tween risks of starvation and predation. Birds have also been found to reduce body mass in response to an increased predation risk. Thord Fransson Thomas P. Weber, Behav Ecol Sociobiol (1997) […]
Spatial behaviour of first-year Blackcaps (Sylvia atricapilla) during thepre-migratory period and during autumn migratory stopovers
Blackcap (Sylvia atricapilla) Science Article 4 abstract The spatial distribution of Blackcaps (Syh.’ia atricapilla) was studied on the basis of ringing recaptures during the post-fledging period and during autumn migratory stopovers on the Courish Spit of the Baltic Sea. The distribution of distances between capture locations of individual birds was compared with the simulation model […]
Field metabolic rates of black-browed albatrosses Thalassarche melanophrys during the incubation stage
Black-browed Albatross (Thalassarche melanophris) Science Article 6 abstract Field metabolic rates (FMR) and activity patterns of black-browed albatrossesThalassarche melanophrys were measured while at sea and on nest during the incubation stage at Kerguelen Island, southwestern Indian Ocean. Activity-specific metabolic rates of five albatrosses at sea
BLACK-BROWED ALBATROSSES FORAGING ON ANTARCTIC KRILL: DENSITY-DEPENDENCE THROUGH LOCAL ENHANCEMENT?
Black-browed Albatross (Thalassarche melanophris) Science Article 5 abstract Many Antarctic seabirds depend on prey that are patchy, cryptic, ephemeral, and unpredictable in location. These predators typically employ two alternative behavioralstrategies for locating resource patches: direct visual or olfactory detection, and indirect detection (local enhancement) by sighting other predators that are already exploiting a patch. DANIEL […]
COLOUR MARKING OF FLEDGLING BLACK-BROWED ALBATROSS ON STEEPLE JASON ISLAND
Black-browed Albatross (Thalassarche melanophris) Science Article 4 abstract To collect at-sea sightings of colour marked fledgling black-browed albatross to determinetheir dispersal pattern and level of interaction with longliners and potentially other vessels, such as trawlers. The long-term project objective is to help target future research into seabird mortality on the Patagonian Shelf Ben Sullivan and […]
Magnetic cues: are they important in Black-browed Albatross Diomedea melanophris orientation?
Black-browed Albatross (Thalassarche melanophris) Science Article 3 abstract Procellariiformes are well known for their excellent homing abilities (see references in Matthews 1968 and Dall’Antonia et al . 1995, Warham 1996). Albatrosses, in particular, have a reputation as skilful oceanic navigators since they can cover enormous distances during foraging flights and pinpoint a specific remote island […]
Global relationships amongst black-browed andgrey-headed albatrosses: analysis of population structureusing mitochondrial DNA and microsatellites
Black-browed Albatross (Thalassarche melanophris) Science Article 7 abstract The population structure of black-browed (Thalassarche melanophrisandT. impavida) andgrey-headed (T. chrysostoma) albatrosses was examined using both mitochondrial DNA(mtDNA) and microsatellite analyses.

SUMMER DISTRIBUTION AND MIGRATION OF NONBREEDINGALBATROSSES: INDIVIDUAL CONSISTENCIES AND IMPLICATIONSFOR CONSERVATION
Black-browed Albatross (Thalassarche melanophris) Science Article 8 abstract Many birds show a surprising degree of intraspecific variability in migratorytendency and choice of wintering site. In this study, we tracked the seasonal movementsof 35 nonbreeding Black-browed Albatrosses Thalassarche melanophrys from South Georgia,including 24 birds followed in two consecutive years. RICHARD A. PHILLIPS et al, Ecology, 86(9), […]
A BLACK-BROWED ALBATROSS THALASSARCHE MELANOPHRISCONSUMES A TERN STERNA SP.
Black-browed Albatross (Thalassarche melanophris) Science Article 1 abstract Albatrosses (Diomedeidae) feed mostly on cephalopods and fish, caught by surface-seizing or shallow diving (del Hoyo et al. 1992). Other prey items, such as seabirds, are taken only occasionally. In a review of the food of albatrosses, Cherel & Klages (1998) listed at least 12 seabird species […]
