Foraging distribution of the black-browed albatross, Thalassarche melanophris, breeding in the Falkland Islands
1.The overall foraging distribution of black-browed albatross from the Falkland Islands is described, based on data from two different stages of the breeding season and two separate breeding sites,
Seasonal occurrence and diet of leopard seals (Hydrurga leptonyx) at Bird Island, South Georgia
Seasonal haul-out patterns and diet of individually marked leopard seals were investigated at Bird Island, South Georgia during the 1983–96 winters, finding considerable inter-annual variation in abundance.
Diving depths of albatrosses
Studies of diving in seabirds have mainly been confined to penguins, alcids and cormorants. There are few data on the depths to which other seabirds dive although some species are known to have
Diving behaviour of the grey-headed albatross
Foraging grey-headed albatrosses spent 86% of the night but only 20% of the day sitting on the sea; most diving activity occurred during daylight. During the broad-guard period of nesting, peaks of
Re-evaluation of Historical Rockhopper Penguin Population Data in the Falkland Islands
Re-calculations of historical Rockhopper Penguin population trends in the Falkland Islands have important implications for the assessment of the global population size and long-term trends of this species.
Arrival and progression of the Swallow Hirundo rustica through Britain
Arrival dates of Swallows from 20 carefully chosen years of the phenological reports of the Royal Meteorological Society (1883–1947) were abstracted. These years represent observations from 1000
Foraging behaviour of emperor penguins as a resource detector in winter and summer
THE emperor penguin (Aptenodytes forsteri), which feeds only at sea, is restricted to the higher latitudes of the antarctic sea-ice habitat1–3. It breeds on the winter fast ice when temperatures
Chick provisioning rates and growth in Blacklbrowed Albatross Diomedea melanophris and Grey-headed Albatross D. chrysostoma at Bird Island, South Georgia
For both species, chick growth rates and peak and fledging mass, but not fledging age, were affected by differences in provisioning rate, and significant changes in meal mass and trip duration occurred within the chick-rearing period.
Census of the Southern Giant Petrel population of the Falkland Islands 2004/2005
From the results obtained here, the conservation status of the Southern Giant Petrel, currently listed as ‘Vulnerable’, could be downgraded to ‘Near Threatened’.
