The birds of the Potter Peninsula, King George Island, South Shetland Islands, Antarctica, 1965-1998
(1998)Records of breeding and non-breeding birds of the Potter Peninsula, King George Island, South Shetland Islands, Antarctica, part of which is a Site of Special Scientific Interest (SSSI), are reviewed from 1965 to 1998. The ... -
Diet and foraging areas of Southern Ocean seabirds and their prey inferred from stable isotopes: review and case study of Wilson’s storm-petrel
(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 ... -
Blood and Intestinal Parasites in Wild Psittaciformes: A Case Study of Burrowing Parrots (Cyanoliseus Patagonus)
(2006)Quantifying parasites is essential for understanding the ecological and evolutionary implications of parasites on their hosts. It is also crucial for many conservation attempts carried out in endangered groups of birds, ... -
Aspects of the breeding biology of the southern rockhopper penguin Eudyptes c. chrysocome and new consideration on the intrinsic capacity of the A-egg
(2008)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 comprehensive understanding of the ... -
Differences in stable isotopes in blood and feathers of seabirds are consistent across species, age and latitude: implications for food web studies
(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 ... -
Stable isotope analysis reveals sexual and environmental variability and individual consistency in foraging of thin-billed prions
(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 ... -
Chick provisioning and nest attendance of male and female Wilson’s storm petrels Oceanites oceanicus
(2009)Seabirds show a range of patterns of sexual size dimorphism and sex-specific parental investment, but the underlying causes remain poorly understood. The aim of the present study was to test two longstanding hypotheses of ... -
Isolation of tetranucleotide microsatellite loci in the burrowing parrot (Cyanoliseus patagonus)
(2009)We isolated seven novel polymorphic microsatellite DNA loci from the burrowing parrot (Cyanoliseus patagonus) and optimised them for future studies of population differentiation and genetic variation. The loci were screened ... -
Trophic segregation of Falkland Islands seabirds: insights from stable isotope analysis
(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, ... -
Hidden dichromatism in the Burrowing Parrot (Cyanoliseus patagonus) as revealed by spectrometric colour analysis
(2009)Bird colour perception differs fundamentally from that of humans. Birds have more cone types in the retina, including UV or violet cones, which enable them to perceive a wider spectral range. Thus, human colour perception ... -
Non-invasive measurement of faecal glucocorticoid metabolites in Upland Geese Chloephaga picta
(2009)Glucocorticoid (GC) hormones rise in response to stressors, including natural events including weather or predator presence, and human activities, such as hunting, scientific research or recreational visits. However, because ... -
Acute stress hyporesponsive period in nestling Thin-billed prions Pachyptila belcheri
(2009)When confronted with acute stressors, vertebrates show a highly conserved evolved sequence of physiological, hormonal and behavioural responses, including the activation of the hypothalamic-pituitary-adrenal axis. Many ...
