Pied Flycatcher (Ficedula hypoleuca) Science Article 3 abstract We tested whether nest visitation rate of parent pied Flycatch ers (Ficedula hypoleuca) is decreased by an experimentally increased predation risk. We simulated predation risk by placing a stuffed Pygmy Owl (Glaucidium passerinzm) in the nest vicinity and by playback of pygmy owl’s whistling. We used Blackbird […]
Provisioning response to manipulation of apparent predation danger by parental Pied Flycatchers
Pied Flycatcher (Ficedula hypoleuca) Science Article 3 abstract We tested whether nest visitation rate of parent pied Flycatch ers (Ficedula hypoleuca) is decreased by an experimentally increased predation risk. We simulated predation risk by placing a stuffed Pygmy Owl (Glaucidium passerinzm) in the nest vicinity and by playback of pygmy owl’s whistling. We used Blackbird […]
Effect of habitat and latitude on nestling diet of Pied Flycatchers Ficedula hypoleuca.
Pied Flycatcher (Ficedula hypoleuca) Science Article 13 abstract Composition and diversity of the nestling diet of Pied Flycatchers Ficedula hypoleuca was compared among 17 European study areas that differed in habitat type (deciduous or coniferous forest). The most abundant foods were butterflies and moths (Lepidoptera), with a high proportion of caterpillars. The proportions of beetles […]

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 […]
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 […]
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 […]
Pied Flycatchers Ficedula hypoleuca travelling from Africa to breed in Europe: differential effects of winter and migration conditions on breeding date
Pied Flycatcher (Ficedula hypoleuca) Science Article 14 abstract In most bird species there is only a short time window available for optimal breeding due to variation in ecological conditions in a seasonal environment. Long-distance migrants must travel before they start breeding, and conditions at the wintering grounds and during migration may affect travelling speed and […]
Effect of Food Availability on Incubation Period in the Pied Flycatcher
Pied Flycatcher (Ficedula hypoleuca) Science Article 6 abstract Incubation maybe stressful because it restricts time for foraging (Walsberg 1983, Murphy and Haukioja 1986). Many bird species in which the females incubate alone, females obtain part of their food from their mates (e.g. Lack 1968, Ricklefs 1974, Lyon and Montgomerie 1985, Lifjeld and Slagsvoid 1986, Nilsson […]
