Pied Flycatcher (Ficedula hypoleuca) Science Article 15 abstract Costs of reproduction might be mediated by a resource-allocation trade-off between immunity and reproductive effort. Recent studies have suggested that the moult-breeding overlap observed mainly in males may affect this trade-off. In order to test whether increased investment in immunity may affect the onset of moult or […]

Return rate age at first breeding and natal dispersal of Pied Flycatchers Ficedula hypoleuca in central spain.
Pied Flycatcher (Ficedula hypoleuca) Science Article 8 abstract Demographic data are presented for the first time for a southern European population of Pied Flycatchers. The return rate of nestlings in both males and females is the highest reported in the literature. This could be due to differences in mortality rate, to differential degree of site-tenacity […]
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 […]

Mass loss in female Pied Flycatchers Ficedula hypoleuca during late incubation: Supplementation fails to support the reproductive stress hypothesis.
Pied Flycatcher (Ficedula hypoleuca) Science Article 12 abstract In most species of altricial birds, females experience great changes in body mass during the reproductive period. Mass loss of females after hatching of the young has commonly been regarded as a result of increased reproductive stress. Alternatively, the loss of body mass during this period is […]
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 […]

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 […]
