M. Honza, Auteur ; I. J. Oien, Auteur ; A. Moksnes, Auteur ; E. Roskaft, AuteurNest survival was studied in relation to nest position of 164 nests of the Reed Warbler Acrocephalus scirpaceus in the Southeastern part of the Czech Republic in 1993. Breeding was successful in 91 (55.5%) cases, whereas 40 (24.4%) were predated[...]

O. Kleven, Auteur ; A. Moksnes, Auteur ; E. Roskaft, Auteur ; G. Rudolfsen, Auteur ; B. G. Stokke, Auteur ; M. Honza, AuteurWe investigated the level of parasitism, egg mimicry and breeding success of cuckoos parasitising four sympatric species of Acrocephalus warblers in southern Moravia, Czech Republic. The parasitism rate was highest in the marsh warbler Acrocepha[...]

I. J. Oien, Auteur ; A. Moksnes, Auteur ; E. Roskaft, Auteur ; M. Honza, AuteurWe investigated the impact of Cuckoo Cuculus canorus parasitism on Reed Warbler Acrocephalus scirpaceus breeding success in the southeastern part of the Czech Republic. Of 1108 nests, 178 (16.1%) were parasitized. We compared several breeding pa[...]

L. C. Grendstad, Auteur ; A. Moksnes, Auteur ; E. Roskaft, AuteurDans Ardea (87(1) 1999)A significant proportion of Redwings Turdus iliacus reject non-mimetic model Cuckoo Cuculus canorus eggs experimentally introduced into their nests. However, very few cases of Cuckoo parasitism have been recorded for this species. In the present[...]

K. S. Hoset, Auteur ; Y. Espmark, Auteur ; A. Moksnes, Auteur ; T. Haugan, Auteur ; M. Ingebrigtsen, Auteur ; M. Lier, AuteurClimatic conditions may have large implications for the reproductive cycle in birds, especially for a small songbird breeding in the high arctic. In three consecutive breeding seasons, the relationship between ambient temperature, and parental f[...]

M. Honza, Auteur ; A. Moksnes, Auteur ; E. Roskaft, Auteur ; B. G. Stokke, AuteurDans Ardea (89(2) 2001)The aim of this study was to investigate the occurrence of Common Cuckoo Cuculus canorus egg morphs in relation to host species and nest sites. The study is based on analyses of museum egg collections and field observations of Common Cuckoo para[...]
Article
E. Roskaft, Auteur ; A. Moksnes, Auteur ; D. Meilvang, Auteur ; V. Bicik, Auteur ; J. Jemelikova, Auteur ; M. Honza, AuteurFailure to recognise own eggs (recognition errors) may be an important selective force behind acceptance of parasitic eggs, leading to a balance between rejecters and acceptors in a host population (the equilibrium hypothesis). We predicted that[...]

S. Skjelseth, Auteur ; A. Moksnes, Auteur ; E. Roskaft, Auteur ; H. L. Gibbs, Auteur ; M. Taborsky, Auteur ; B. Taborsky, Auteur ; M. Honza, Auteur ; O. Kleven, AuteurMicrosatellite DNA markers were used to investigate parentage relationships in a population of common cuckoo Cuculus canorus. Thirty adults and 55 nestlings were genotyped at six loci from blood samples collected over a four-year period. To test[...]
Article
T. Amundsen, Auteur ; P. T. Brobakken, Auteur ; A. Moksnes, Auteur ; E. Roskaft, AuteurThe evolutionary equilibrium hypothesis explains the existence of both acceptors and rejecters of brood parasite eggs within a host population as resulting from a balance between the costs of acceptance and the costs of recognition errors. In su[...]
