Reduced immunocompetence of nestlings in replacement clutches of the European magpie (Pica pica)
Laying date is one of the most important determinants of reproductive success and recruitment probability in birds. Late breeders usually £edge fewer chicks than individuals with earlier breeding dates, and £edglings produced late in the season have high mortality rates. Food availability and nestling mass have been evoked as the principal mechanistic links between laying date and o¡spring surv...
متن کاملMortality associated with avian reovirus infection in a free-living magpie (Pica pica) in Great Britain
BACKGROUND Avian reoviruses (ARVs) cause a range of disease presentations in domestic, captive and free-living bird species. ARVs have been reported as a cause of significant disease and mortality in free-living corvid species in North America and continental Europe. Until this report, there have been no confirmed cases of ARV-associated disease in British wild birds. CASE PRESENTATION Sporad...
متن کاملOxidative Stress Mediates Physiological Costs of Begging in Magpie (Pica pica) Nestlings
BACKGROUND Theoretical models predict that a cost is necessary to guarantee honesty in begging displays given by offspring to solicit food from their parents. There is evidence for begging costs in the form of a reduced growth rate and immunocompetence. Moreover, begging implies vigorous physical activity and attentiveness, which should increase metabolism and thus the releasing of pro-oxidant ...
متن کاملFeather microstructure of the black-billed magpie (Pica pica sericea) and jungle crow (Corvus macrorhynchos).
The jungle crow (Corvus macrorhynchos) distribution stretches from eastern Eurasia continent to southeastern Asia. The distribution of the black-billed magpie (Pica pica sericea) stretches from Korea and China to the Kyushu area in Japan. They are both in the Family, Corvidae, and have iridescent feather colors, but the iridescent feather color of the black-billed magpie is more remarkable than...
متن کاملEffect of Incubation on Bacterial Communities of Eggshells in a Temperate Bird, the Eurasian Magpie (Pica pica)
Inhibitory effect of incubation on microbial growth has extensively been studied in wild bird populations using culture-based methods and conflicting results exist on whether incubation selectively affects the growth of microbes on the egg surface. In this study, we employed culture-independent methods, quantitative PCR and 16S rRNA gene pyrosequencing, to elucidate the effect of incubation on ...
