Magpie (Pica pica) Science Article 11 abstract In many animals immunity is not fully developed until adulthood but the youngstill need protection against various sets of pathogens. Thus, bird nestlings are highlydependent on antibodies received from their mother (in the eggs) during their rapidearly growth period. MARJO PIHLAJA, HELI SIITARI and RAUNO V. ALATALO, Journal […]

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 […]

The quality of pied flycatcher (Ficedula hypoleuca) and great tit (Parus major) females in an air pollution gradient
Pied Flycatcher (Ficedula hypoleuca) Science Article 1 abstract We studied whether pied flycatcher (Ficedula hypoleuca) and great tit (Parus major) females differed in quality between polluted and unpolluted habitats. Comparing female condition between incubation and nestling periods, we aimed at testing whether biometric differences in F. hypoleuca females were caused by assortative settlement (i.e. intraspecific […]
A trade-off between two resource-demanding functions: post-nuptial moult and immunity during reproduction in male pied flycatchers
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 […]
