Article
Anton Antonov, Auteur ; Bard G. Stokke, Auteur ; Peter S. Ranke, Auteur ; Frode Fossoy, Auteur ; Arne Moksnes, Auteur ; Eivin Roskaft, AuteurThere is at present considerable variation in the level of antiparasite defences among different host species of avian brood parasites, but in many potential hosts some individuals reject poorly matching parasite eggs. Here we present unique abs[...]
Article
Anton Antonov, Auteur ; Bard G. Stokke, Auteur ; Arne Moksnes, Auteur ; Eivin Roskaft, AuteurThe breeding ecology of eastern olivaceous warblers Hippolais pallida is poorly known. In this study, we provide data on nest site selection and breeding parameters of the species in a population in northwestern Bulgaria, the only one known to b[...]
Article
Anton Antonov, Auteur ; Dimitrinka Atanasova, AuteurThis study explored colony pattern, interspecific association and nest-site selection of two closely related species of swift. Common Swift (Apus apus) and Pallid Swift (A. pallidus) in Sofia city, Bulgaria. The numbers and locations of nests we[...]
Article
Anton Antonov, Auteur ; Bard G. Stokke, Auteur ; Arne Moksnes, Auteur ; Eivin Roskaft, AuteurUsing multiple logistic regression analysis, we investigated the influence of nest site characteristics, laying date and nest size in marsh warblers Acrocepbalus palustris on the risk of parasitism by common cuckoos cuculus canorus. Marsh warble[...]

Canchao Yang, Auteur ; Bard G. Stokke, Auteur ; Anton Antonov, Auteur ; Yan Cai, Auteur ; Suhua Shi, Auteur ; Arne Moksnes, Auteur ; Eivin Roskaft, Auteur ; Anders P. Moller, Auteur ; Wei Liang, Auteur ; Tomáš Grim, AuteurHow do potential hosts escape detrimental interactions with brood parasites? Current consensus is that hole-nesting and granivorous birds avoid brood parasites, like common cuckoos Cuculus canorus, by their inaccessible nest-sites and food unsui[...]

Canchao Yang, Auteur ; Anton Antonov, Auteur ; Yan Cai, Auteur ; Bard G. Stokke, Auteur ; Arne Moksnes, Auteur ; Eivin Roskaft, Auteur ; Wei Liang, AuteurWe documented brood parasitism by the poorly studied Large Hawk-Cuckoo on a previously unknown host species, the Chinese Babax. Furthermore, we describe a new egg colour for the Large Hawk-Cuckoo. The parasitism rate of Chinese Babax nests over [...]

Canchao Yang, Auteur ; Longwu Wang, Auteur ; Yu-Cheng Hsu, Auteur ; Anton Antonov, Auteur ; Arne Moksnes, Auteur ; Eivin Roskaft, Auteur ; Wei Liang, Auteur ; Bard G. Stokke, AuteurBirds are capable of seeing the ultraviolet light (UV) spectrum and as a consequence have evolved UV-reflective structures with signalling functions. Avian eggs also reflect in the UV spectrum but the importance of UV egg matching in egg rejecti[...]
