Red-breasted Flycatcher (Ficedula parva) Science Article 1 abstract I studied arrival time, breeding phenology, and breeding success in relation to the age class (second year and older) of male red-breasted flycatchers for six breeding seasons (2000-2005) in the prim val Bialowieza Forest, eastern Poland. Older males, i.e. older than two years (ASY), arrived on average […]

First evidence of phenological change in a transcontinental migrant overwintering in the Indian sub-continent: the Red-breasted Flycatcher Ficedula parva
Red-breasted Flycatcher (Ficedula parva) Science Article 3 abstract We analysed data on the Red-breasted Flycatcher Ficedula parva collected in old- growth, oak-hornbeam stands in the primeval Forest, Poland during 1973- 2002. In this period, the Red-breasted Flycatcher’s return to its breeding sites became sig nificantly earlier whilst population size did not change significantly. We show […]
Is the later arrival of young male red-breasted flycatchers ( Ficedula parva ) related to their physical condition?
Red-breasted Flycatcher (Ficedula parva) Science Article 2 abstract Intraspecific variation in the arrival time of migratory birds to breeding grounds is common. Although this phenomenon has been explained in various ways, the condition-dependency of arrival is often evoked. I analyzed the arrival time of male red-breasted flycatchers Ficedula parva, a long-distance migratory passerine, in relation […]
Niche partitioning of two Palearctic passerinemigrants with Afrotropical residents in theirWest African winter quarters
Pied Flycatcher (Ficedula hypoleuca) Science Article 5 abstract In bird migration systems, the question of coexistence and competition of migrants with residents in the nonbreeding season andtheir role in shaping the evolution of present avian communities is much debated. However, conclusions are often drawn ina speculative way. In the Palearctic-African bird migration system, many studies […]

Do parasitic mites decrease growth of nestling Pied Flycatchers Ficedula hypoleuca?
Pied Flycatcher (Ficedula hypoleuca) Science Article 10 abstract The effect of a parasitic mite Dermanyssus hirundinis on the growth and survival of nestling Pied Flycatcher Ficedula hypoleuca was tested by an experiment where the parasite level was reduced in half of the nest boxes using an insecticide, Although the abundance of mites was significantly reduced […]

Individual fluctuating asymmetry in pied flycatchers(Ficedula hypoleuca) persists across moults,but is not heritable and not related to fitness
Pied Flycatcher (Ficedula hypoleuca) Science Article 7 abstract Neither composite nor single trait fluctuating asymmetry was associated withindividual condition, attractiveness, reproductive success or survival. Estimated heritabilitiesof signed and unsigned fluctuating asymmetry were low and non-significant. This impliesthat fluctuating asymmetry was a poor predictor of genetic quality or phenotypic condition.Among-individual differences in fluctuating asymmetry therefore had […]
Sexual size dimorphism and sources of variation in the growth of wing feathers in nestling Pied Flycatchers Ficedula hypoleuca
Pied Flycatcher (Ficedula hypoleuca) Science Article 4 abstract I report a 5-year field study of the growth of flight feathers, as scored by the lengths of the wing and first-primary feather, of Pied Flycatcher nestlings when they were 13 days old. Further evidence to that already published for gender differences in growth of different traits […]
Environmental, genetic and maternal components of immunocompetence of nestling pied flycatchers from a cross-fostering study
Pied Flycatcher (Ficedula hypoleuca) Science Article 16 abstract Genetic, environmental and maternal effects can all affect the phenotypic expression of a trait.Through cross-fostering experiments in nesting birds, variation due to genetic and environmentaleffects can be partitioned and identified as being due to nest of origin and nest ofrearing in a two-factor nested analysis of variance […]
