Linked selection and recombination rate variation drive the evolution of the genomic landscape of differentiation across the speciation continuum of Ficedula flycatchers.
TLDR
It is concluded that the heterogeneous landscape of differentiation in Ficedula flycatchers evolves mainly as the result of background selection and selective sweeps in genomic regions of low recombination, and the necessity of incorporating linked selection as a null model to identify genome regions involved in adaptation and speciation is emphasized.

Large–scale geographical variation confirms that climate change causes birds to lay earlier
TLDR
Trends in spring temperature varied markedly between study sites, and across populations the advancement of laying date was stronger in areas where the spring temperatures increased more, giving support to the theory that climate change causally affects breeding date advancement. Expand
Female collared flycatchers adjust yolk testosterone to male age, but not to attractiveness
TLDR
It is shown that free-living females of the collared flycatcher (Ficedula albicollis), a small passerine bird, do not produce larger eggs or deposit more testosterone into eggs when mating with attractive males, contrary to the prediction of the differential allocation hypothesis, and higher yolk testosterone concentrations in eggs laid for young than older males are found.

Flycatcher song in allopatry and sympatry – convergence, divergence and reinforcement
TLDR
Reinforcement has reduced the frequency of mixed singing in the pied flycatcher and caused a divergence in the song of the collared flycatchers, suggesting that mixed song may increase the rate of maladaptive hybridization. Expand
Behavioural syndromes and trappability in free-living collared flycatchers, Ficedula albicollis
TLDR
The consistency of behavioural responses across three ecological situations in male collared flycatchers is studied, suggesting that behavioural types may be potential subjects for reproductive and life history adaptations and suggesting that capturing protocols may not randomly sample the observed population. Expand
Egg composition in relation to social environment and maternal physiological condition in the collared flycatcher
TLDR
The present study investigated whether experimentally elevated social interactions and number of neighbouring pairs influence yolk composition of collared flycatchers and found that yolk lutein and immunoglobulin concentrations were related to the female’s H/L ratio, and yolks antioxidant and α-tocopherol levels showed a seasonal increase and were positively related to a female's plasma carotenoid level. Expand
Carotenoids in the egg yolks of collared flycatchers (Ficedula albicollis) in relation to parental quality, environmental factors and laying order
TLDR
It was found that carotenoid concentration was positively associated with caterpillar supply at the time of egg formation, which suggests a proximate constraint of carOTenoid availability on yolk composition and suggests that collared flycatchers pursue a compensatory, “brood survival” strategy. Expand
Eggshell coloration in relation to male ornamentation, female condition and egg quality in the collared flycatcher Ficedula albicollis
TLDR
A positive association between egg colour saturation and yolk lutein concentration is found and it is found that intensity of blue-green coloration increased with laying order between the first and fifth eggs, which could be the result of the seasonal improvement of caterpillar supply. Expand
The Design of Artificial Nestboxes for the Study of Secondary Hole-Nesting Birds: A Review of Methodological Inconsistencies and Potential Biases
TLDR
The types of descriptive data that should be included in the methods sections of relevant manuscripts are listed to improve the reliability and usefulness of research based on long-term studies of any secondary hole-nesting species using artificial nestboxes for breeding or roosting. Expand
Evolutionary analysis of the female-specific avian W chromosome
TLDR
A draft assembly of the non-recombining region of the collared flycatcher W chromosome is presented, containing 46 genes without evidence of female-specific functional differentiation, demonstrating evolutionary stable matrilineal inheritance of this nuclear–cytonuclear pair of chromosomes. Expand
