The size and status of the population of southern sea lions Otaria flavescens in the Falkland Islands
Abstract Pup production of southern sea lions in the Falkland Islands was estimated to be 80,550 (total population ca. 380,000) in 1937, but by 1965 it had fallen to around 6000; a 93% reduction inExpand

Movements, winter distribution and activity patterns of Falkland and brown skuas: Insights from loggers and isotopes
In the first published study of the wintering ranges and activity patterns of skuas from any colony, we combined tracking (geolocator) and stable isotope analysis in a comparison of migra- tionExpand

Population census and nesting habitat selection of thin-billed prion Pachyptila belcheri on New Island, Falkland Islands
Seabirds have the potential to be used as indicators for monitoring changes in the southern oceans. However, many species and populations are still poorly known. The thin-billed prion ( PachyptilaExpand

Introduced mammals coexist with seabirds at New Island, Falkland Islands: abundance, habitat preferences, and stable isotope analysis of diet
The largest known colony of Thin-billed prions Pachyptila belcheri has been coexisting with introduced mammals for more than 100 years. Three of the introduced mammals are potential predators ofExpand

Begging and provisioning of thin-billed prions, Pachyptila belcheri, are related to testosterone and corticosterone
Vigorous begging is usually seen as an expression of parent–offspring conflict over limited resources. Chicks signal need by begging, but the evolution of honest signals requires the signals to beExpand

Aspects of the breeding biology of the southern rockhopper penguin Eudyptes c. chrysocome and new consideration on the intrinsic capacity of the A-egg
The rockhopper penguins Eudyptes chrysocome have recently been split into the northern E. moseleyi and the southern E. chrysocome rockhopper penguin. It is therefore crucial to have a comprehensiveExpand

Applying ecology to conservation: tracking breeding penguins at New Island South reserve, Falkland Islands
1. Understanding how penguins use marine habitats around the Falkland Islands is critical to reducing conflicts with human activities. We present satellite tracking data that show how three speciesExpand

Sea surface temperatures and behavioural buffering capacity in thin‐billed prions Pachyptila belcheri: breeding success, provisioning and chick begging
Seabirds are important predators in marine ecosystems and are commonly used to monitor the productivity of their marine environments. However, different measures of seabird breeding success differ inExpand

Inter-annual changes in diet and foraging trip lengths in a small pelagic seabird, the thin-billed prion Pachyptila belcheri
Central place foragers are constrained in their foraging distribution by the necessity to return to their nest site at regular intervals. In many petrels that feed on patchily distributed prey fromExpand

Brood-guarding duration in black-browed albatrosses Thalassarche melanophris: temporal, geographical and individual variation
In birds, the period spent brooding or guarding young chicks is highly variable, but such variation has seldom been studied. Previous single-year studies of Antarctic petrels Thalassoica antarcticaExpand
