Revisiting Lévy flight search patterns of wandering albatrosses, bumblebees and deer
The study of animal foraging behaviour is of practical ecological importance, and exemplifies the wider scientific problem of optimizing search strategies. Lévy flights are random walks, the stepExpand

Tracking of Arctic terns Sterna paradisaea reveals longest animal migration
The study of long-distance migration provides insights into the habits and performance of organisms at the limit of their physical abilities. The Arctic tern Sterna paradisaea is the epitome of suchExpand

Influence of trophic position and foraging range on mercury levels within a seabird community
Seabirds are often advocated as biomonitors for marine contaminants such as mercury (Hg). However, contaminant levels can vary widely depending on among-individual and among-species variation inExpand

Changes in fisheries discard rates and seabird communities
It is clear that discards from commercial fisheries are a key food resource for many seabird species around the world. But predicting the response of seabird communities to changes in discard ratesExpand

Stable isotopes indicate sex-specific and long-term individual foraging specialisation in diving seabirds
An important aspect of foraging ecology is the extent to which different individuals or genders within a population exploit food resources in a different manner. For diving seabirds, much of thisExpand

Annual variation in diets, feeding locations and foraging behaviour of gannets in the North Sea: flexibility, consistency and constraint
Many seabirds nesting in areas bordering the North Sea have recently experienced large annual variation in breeding success, including reproductive failures in some cases. In contrast, the breedingExpand

Foraging and provisioning strategies of the light-mantled sooty albatross at South Georgia: competition and co-existence with sympatric pelagic predators
Foraging and provisioning strategies of the light-mantled sooty albatross (LMSA) Phoebetria palpebrata were studied during chick-rearing at Bird Island, South Georgia, in January to May 2003.Expand

Stable isotope evidence of diverse species-specific and individual wintering strategies in seabirds
Although there is increasing evidence that climatic variations during the non-breeding season shape population dynamics of seabirds, most aspects of their winter distribution and ecology remainExpand

Contrasting foraging strategies of gannets Morus bassanus at two North Atlantic colonies: foraging trip duration and foraging area fidelity
Seabirds may be able to increase their foraging efficiency by learning the whereabouts of predictable sources of prey and returning repeatedly to these locations. The occurrence of such foraging areaExpand

Foraging ecology of albatrosses and petrels from South Georgia: two decades of insights from tracking technologies
1. A wide range of instrumentation has been deployed on albatrosses and petrels at Bird Island, South Georgia, in studies dating back to the mid-1980s. Early results indicated the huge distances thatExpand
