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 […]

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 […]
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 […]

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 […]
