Article
Václav Jelínek, Auteur ; Michal Šulc, Auteur ; Karel Weidinger, Auteur ; Marcel Honza, AuteurDespite the fact that parent-absent begging (PAB) has been studied as a communication tool during competition between nestlings for food or as a signal of need, its role in nest predation has been poorly investigated. In this study we examined w[...]
Article
Libor Praus, Auteur ; Arne Hegemann, Auteur ; B. Irene Tieleman, Auteur ; Karel Weidinger, AuteurPredation is a major cause of breeding failure in bird species with open nests. Although many studies have investigated nest predation rates, direct identification of nest predators is sporadic, especially in (semi-)natural habitats. We quantifi[...]

Predators and nest success of Sky Larks Alauda arvensis in large arable fields in the Czech Republic
Libor Praus, Auteur ; Karel Weidinger, AuteurCapsule Nest failure owing to a range of predators was high, but the level and specificity of nest depredation cannot be generalised. Aims To determine fates and predators of Sky Lark nests in conventionally managed arable fields in the Czech Re[...]
Article
Karel Weidinger, Auteur ; Miroslav Král, AuteurLong-distance migrants may respond to climate change in breeding, wintering or staging area by changing their phenology. The geographical variation in such responses (e.g. coastal vs. continental Europe) and the relative importance of climate at[...]

Article
Karel Weidinger, AuteurNest 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[...]
Article
Karel Weidinger, AuteurResearchers are moving their attention away from the Mayfield method of estimating nest success to advanced nest survival models that can be implemented within statistical software packages. In spite of this, little attention has been paid to de[...]
Article
Karel Weidinger, AuteurVideotaping is currently recognized as the most reliable method of predator identification at active bird nests but it is relatively expensive and labour intensive. While the number of published studies has increased over the past 10 years, the [...]
Article
Karel Weidinger, AuteurI used time-lapse videotaping to identify predators of open songbird nests in fragmented deciduous woodland (nine plots, 2-10 ha each) in the Czech Republic from 2002 to 2006. I documented 22 species of predators at 171 nests of 13 species (main[...]
Article
Karel Weidinger, Auteur ; Václav Pavel, AuteurAntarctic terns have to co-exist in a limited space with their major nest predator, the skuas. We conducted artificial nest experiments to evaluate the roles of parental activity, nest location and nest and egg crypsis in this simple predatorpre[...]
Article
Accurate determination of nest fates and nest predators is possible through continuous video monitoring, but such monitoring is relatively expensive and labor intensive. If documenting of the timing of nest termination events is Sufficient, then[...]
