We isolated and characterised six novel microsatellite loci for paternity analysis in the sand martin Riparia riparia, by screening an enriched genomic library. In addition, we tested 16 already published microsatellite markers, five of which we[...]

Fledgling birds are notoriously difficult to find and capture because of their cryptic behavior. As a result, researchers usually affix transmitters to nestlings to study aspects of post-fledging ecology. However, parents may attempt to remove n[...]

Natal dispersal is a key component of population dynamics in birds. It guarantees the genetic exchange of populations, favours range expansions and reduces intraspecific competition. In general, natal philopatry of migratory passerines is quite [...]

Home range and territoriality of Australian owlet-nightjars Aegotheles cristatus in diverse habitats
Lisa I. Doucette, Auteur
Sedentary Australian owlet-nightjars Aegotheles cristatus roost in cavities year-round, and are thought to mate for life and maintain stable home ranges throughout the year. These factors lead to the prediction that they should be highly territo[...]

Nest predation patterns and processes cannot be understood without studying the behaviour of predators. I videotaped the behaviour of 22 species of predators at 171 depredated nests of 13 passerine species, in woodland in the Czech Republic. Abo[...]

The preference for foraging in groups and the effect of physiognomic factors of a habitat on its use by foraging Whinchats (Saxicola rubetra) was studied during spring migration stopover in a mosaic cultural landscape at the SE Adriatic coast. E[...]

The Kyrgyz population of the bar-headed goose Anser indicus has declined dramatically during the past decades. Human persecution during migration and habitat loss at stopover and wintering sites are commonly regarded as most serious threats. How[...]

Evidences for phenological changes in response to climate change are now numerous. One of the most documented changes has been the advance of spring arrival dates in migratory birds. However, the effects of climate change on subsequent events of[...]

The challenge hypothesis (Wingfield et al. in Am Nat 136:829-846, 1990) predicts that circulating testosterone increases when socially monogamous male birds are challenged during breeding. Although the challenge hypothesis has been confirmed in [...]
