Magpie (Pica pica) Science Article 5 abstract The Magpie is a residential non-migratorybird (Goodwin, 1986; Birkhead, 1991).Each pair of birds controls its own territoryall the year around. However, in winter thismonogamous bird sleeps in communal roosts.Birkhead (1991) discussed some of the mainideas, which may explain this behaviour.

SERIES OF NESTS OF THE MAGNOLIA WARBLER.
Magnolia Warbler (Dendroica magnolia) Science Article 2 abstract The warblers were late in 1907. The cold, backward spring was behind time in unfolding catkin and leaf whereon the insect hosts prey, and the warblers who live on the insect life keep pace with the resurrection and birth of moth and butterfly, mosquito and aphis, caterpillar […]
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 […]

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 […]
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 […]
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 […]
