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 […]

STATUS OF THE PHILADELPHIA VIREOIN BRITISH COLUMBIA

Philadelphia Vireo (Vireo philadelphicus) Science Article 1 abstract The Philadelphia Vireo (Vireo philadelphicus) is an uncommon, forest-dwelling, neotropical migrantrestricted in British Columbia to the Boreal Plains and Taiga Plains ecoprovinces. It is a habitatgeneralist, but its distribution is linked with the distribution of deciduous-dominated forests. Relativelyfew data exist on populations, habitat use, or breeding productivity. […]

Parental care in Pied Flycatchers Ficedula hypoleuca: Energy expenditure in relation to plumage colour and mating status

Pied Flycatcher (Ficedula hypoleuca) Science Article 11 abstract Females may benefit from expending more resources in care of offspring sired by sexually attractive males than by those of unattractive males in species with biparental care. Attractive males may therefore reduce their share of parental expenditure to increase own survivorship and to further mating success. On […]

Environmental restrictions on reproduction in the Pied Flycatcher Ficedula hypoleuca.

Pied Flycatcher (Ficedula hypoleuca) Science Article 9 abstract I compared two populations of Pied Flycatchers Ficedula hypoleuca breeding in a coniferous forest with adverse weather conditions (‘marginal habitat’) and in a deciduous forest with a more favourable climate (‘good habitat’). Female mass was significantly larger during the reproductive cycle in the ‘good habitat’. The incubation […]
