Behavioural plasticity in the early breeding season of pelagic seabirds : a case study of thin-billed prions from two oceans
Quillfeldt, Petra; Weimerskirch, Henri; Masello, Juan F.; Delord, Karine; McGill, Rona A. R.; Furness, Robert W.; Cherel, Yves (2019)Background: In long-lived seabirds that migrate large distances independently of each other, the early part of the breeding season is crucially important for a successful reproductive attempt. During this phase, pair bonds ... -
Diet and foraging areas of Southern Ocean seabirds and their prey inferred from stable isotopes: review and case study of Wilson’s storm-petrel
Quillfeldt, Petra; McGill, Rona A.R.; Furness, Robert W. (2005)Analysis of stable isotope ratios in animal tissues has emerged as a powerful tool for determining the trophic level and composition of prey and foraging location. We summarize here data on the stepwise trophic enrichment ... -
Differences in stable isotopes in blood and feathers of seabirds are consistent across species, age and latitude: implications for food web studies
Quillfeldt, Petra; Bugoni, Leandro; McGill, Rona A.R.; Masello, Juan F.; Furness, Robert W. (2008)Stable isotopes of growing feathers and blood both represent assimilated diet, and both tissues are used to study the diet and foraging distribution of marine and terrestrial birds. Although most studies have assumed that ... -
Half a world apart? Overlap in nonbreeding distributions of Atlantic and Indian Ocean thin-billed prions
Quillfeldt, Petra; Cherel, Yves; Masello, Juan F.; Delord, Karine; McGill, Rona A. R.; Furness, Robert W.; Moodley, Yoshan; Weimerskirch, Henri (2015)Distant populations of animals may share their non-breeding grounds or migrate to distinct areas, and this may have important consequences for population differentiation and dynamics. Small burrow-nesting seabirds provide ... -
Moving polewards in winter: a recent change in the migratory strategy of a pelagic seabird?
Quillfeldt, Petra; Masello, Juan F.; McGill, Rona A.R.; Adams, Mark; Furness, Robert W. (2010)Background: During the non-breeding period, many birds migrate to milder areas, found closer to the equator than their breeding sites. Opposite movements are very rare. In the Southern Ocean, the abundance of 13C declines ... -
Stable isotope analysis reveals sexual and environmental variability and individual consistency in foraging of thin-billed prions
Quillfeldt, Petra; McGill, Rona A.R.; Masello, Juan F.; Weiss, Felix; Strange, Ian J.; Brickle, Paul; Furness, Robert W. (2008)Based on growing knowledge on the distribution of stable isotopes in marine food webs, a powerful tool to study movements and trophic position of seabirds has been developed. Here we provide an updated review of isotope ... -
Trophic segregation of Falkland Islands seabirds: insights from stable isotope analysis
Weiss, Felix; Furness, Robert W.; McGill, Rona A.R.; Strange, Ian J.; Masello, Juan F.; Quillfeldt, Petra (2009)Seabird colonies provide rare opportunities to study trophic segregation in an entire bird community. We here present data on nitrogen and carbon isotope ratios of eight species of seabirds from New Island, Falkland Islands, ...
