Reed Bunting (Emberiza schoeniclus) Science Article 7 abstract Females of many socially monogamous species accept or even actively seek copulations outside the socialpair bond. As females cannot increase the number of offspring with promiscuous behaviour, the questionarises why they engage in extra-pair mating. Stefan M. Suter et al, Proc. R. Soc. B, 2007 Download article […]

Older male reed buntings are more successful at gainingextrapair fertilizations
Reed Bunting (Emberiza schoeniclus) Science Article 8 abstract The importance of extrapair paternity (EPP) as an aspect of mixed reproductive strategies is currently thefocus of many studies. Since females have at least some control over the occurrence of inseminations, theyare expected to engage in extrapair copulations only if they benefit, for instance through gaining highqualityor […]

Habitat selection of two Acrocephalus warblers breeding in reed beds near Malacky (Western Slovakia).
Reed-Warbler (Acrocephalus scirpaceus) Science Article 4 abstract The study was carried out in 1999 and 2000 at three sites near Malacky, WSlovakia: Jakubovske rybniky ?shponds, Jakubovske
Intraspecific variation in the wing shape of the long-distance migrant Reed Warbler Acrocephalus scirpaceus: effects of age and distance of migration
Reed-Warbler (Acrocephalus scirpaceus) Science Article 1 abstract The wing morphology of Reed Warblers Acrocephalus scirpaceus was studied during the breeding and non-breeding cycle in a western Mediterranean area. Wing morphology was first analysed by means of a principal component analysis (PCA) on primary lengths, which corrects for allometric effects on wing shape. Two-way ANOVAs were […]
Movement patterns of European Reed Warblers Acrocephalus scirpaceus and Sedge Warblers A. schoenobaenus before and during autumn migration.
Reed-Warbler (Acrocephalus scirpaceus) Science Article 7 abstract The foraging movements of European Reed Warblers Acrocephalus scirpaceus and Sedge Warblers Acrocephalus schoenobaenus at migratory stopover sites were studied by comparing the frequency distribution of distances between capture-recapture localities of individual birds with a simulation model of a random distribution of movements. The results indicate that Reed […]
Stabilising selection on wing length in reed warblers Acrocephalus scirpaceus
Reed-Warbler (Acrocephalus scirpaceus) Science Article 6 abstract The size of an animal is of utmost importance for its overall success and each species is thought to have its own optimal size. If this is true, size traits ought to be under stabilising selection unless the animal is living in a highly unstable environment. Wing length […]
Migration routes of North European Reed Warblers Acrocephalusscirpaceus
Reed-Warbler (Acrocephalus scirpaceus) Science Article 5 abstract Migration routes of expanding North European Reed Warbler populations were investigated by means of more than 2500 recoveries of birds ringed in Norway, Sweden and Finland. We found different autumn directions: from Norway SSW 195 deg -200 deg , from Sweden SSW-SW 211 deg -216 deg , and […]
Gap crossing decisions by reed warblers (Acrocephalus scirpaceus)in agricultural landscapes
Reed-Warbler (Acrocephalus scirpaceus) Science Article 3 abstract To meet the need for research on the requirements for corridors for marshland birds, this study set out toquantify gap crossing decisions made by reed warblers moving through the landscape. In three experiments,reed warblers were released into landscape situations with di?erent gap sizes and their movement towardsreed patches […]
The decline of the Ring Ouzel Turdus torquatus in Britain: evidence from bird observatory data
Ring Ouzel (Turdus torquatus) Science Article 1 abstract Analysis of British and Irish bird observatory data from 1970-1998 shows that the number of Ring Ouzel Turdus torquatus bird days has declined significantly in spring at western observatories through which British-breeding birds pass, but not at east coast observatories through which Fennoscandian breeders pass. The extent […]
