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[...]
Article
M. Honza, Auteur ; S. M. Kuiper, Auteur ; M. I. Cherry, AuteurThe red-chested cuckoo Cuculus solitarius parasitises many passerines in Africa, but some common species sympatric with this brood parasite are rarely used as hosts. We tested the responses of three turdid hosts to parasitism with artificial cuc[...]

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[...]
Article
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[...]
Article
P. Prochazka, Auteur ; M. Honza, AuteurIn a coevolutionary arms race between a brood parasite and its host, both species are expected to evolve adaptations and counteradaptations, such as egg mimicry and egg discrimination. The Common Whitethroat (Sylvia communis) is a regular Common[...]

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[...]

M. Honza, Auteur ; J. Picman, Auteur ; T. Grim, Auteur ; V. Novak, Auteur ; M. Capek, Auteur ; V. Mrlik, AuteurBrood parasitism represents a unique mode of avian reproduction that requires a number of adaptations. For example, to reduce chances of puncture ejection of their eggs by small hosts, brood parasites may have been selected for laying eggs of un[...]

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[...]

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[...]

R. Lezalova, Auteur ; E. Tkadlec, Auteur ; M. Obornik, Auteur ; J. Simek, Auteur ; M. Honza, AuteurIn birds with hatching asynchrony and sexual size dimorphism, chicks hatched earlier and later in the laying sequence usually suffer different mortalities due to uneven abilities to compete for food, especially in poor years. If sexes differ in [...]
