To assess whether increasing numbers of Siberian vagrants observed in Europe in recent autumns can be linked to climate change, we predicted changes in the climatic suitability of the breeding ranges of 46 Siberian bird species known to show vag[...]

Thermal imaging, or infrared thermography, has been used in avian science since the 1960s. More than 30 species of birds, ranging in size from passerines to ratites, have been studied using this technology. The main strength of this technique is[...]

Timing of breeding and offspring number covary with plumage colour among Gyrfalcons Falco rusticolus
Jeff A. Johnson, Auteur ;

Plumage colour variation exists among Gyrfalcons throughout their Arctic and sub-Arctic circumpolar distribution, ranging from white through silver and grey to almost black. Although different colour variants coexist within many populations, a f[...]

The intensity of selection exerted by brood parasites on their hosts depends on the proportion of nests that are parasitized and the fitness costs of parasitism. Nest detection by brood parasites influences the probability of parasitism, and we [...]

Estimates of refuelling rates in migrating waders are best based on intra-seasonal recaptures of individually marked birds. This method, however, has methodological problems associated with capture effects and difficulties in attaining sufficien[...]
