A sexually selected character displacement in flycatchers reinforces premating isolation
TLDR
In populations where two species coexist, it is shown that female choice selects for a divergence in male plumage colour and that the resulting character displacement reduces the frequency of hybridization. Expand
Sex Chromosome-Linked Species Recognition and Evolution of Reproductive Isolation in Flycatchers
TLDR
It is demonstrated that species recognition is inherited on the Z chromosome, which is also the known location of species-specific male plumage traits and genes causing low hybrid fitness, suggesting that the sex chromosomes may be a hotspot for adaptive speciation. Expand
Differential species recognition abilities of males and females in a flycatcher hybrid zone
TLDR
In two aviary experiments, the hypothesis that males and females prefer to mate conspecifically was tested and it was found that the female showed the strongest sexual response to theconspecific male and the males showed no preference for conspespecific or heterospecific female flycatchers. Expand
Can environmental fluctuation prevent competitive exclusion in sympatric flycatchers?
TLDR
The analysis suggests a march towards competitive exclusion of the pied flycatcher during warm periods, however, competitive exclusion is apparently prohibited on a local scale because intraspecific competition among individual collared flycatchers intensifies when they are forced to cope with severe environmental conditions, promoting the temporary and local presence of piedFlycatchers.

Climatic effects on arrival and laying dates in a long‐distance migrant, the Collared Flycatcher Ficedula albicollis
TLDR
Variation in first arrival dates and laying dates of the Collared Flycatcher Ficedula albicollis in a central European population, from 1973 to 2002 is analysed to suggest later departure from wintering grounds and faster migration across staging areas in warmer conditions. Expand
Breeding latitude leads to different temporal but not spatial organization of the annual cycle in a long‐distance migrant
The temporal and spatial organization of the annual cycle according to local conditions is of crucial importance for individuals' fitness. Moreover, which sites and when particular sites are used cExpand
Climate- and resource-driven long-term changes in dormice populations negatively affect hole-nesting songbirds
TLDR
It was found that the increasing dormice abundance was the main factor causing high brood losses in birds, while the timing of breeding in birds had a variable effect between bird species. Expand
Linking events throughout the annual cycle in a migratory bird—non-breeding period buffers accumulation of carry-over effects
TLDR
The results demonstrate tight links between spatially and temporally distinct phases of the annual cycles of migrants which can have significant implications for population dynamics and demonstrate that the non-breeding period may serve as a buffer to overcome high energy expenditure during the previous breeding season and prevent further accumulation of carry-over effects in migrating birds.

EXPERIMENTAL EVIDENCE FOR INTERSPECIFIC FEMALE MIMICRY IN SYMPATRIC FICEDULA FLYCATCHERS
TLDR
An experimental test of the hypothesis of interspecific female mimicry for color divergence in male pied flycatchers, a closely related species of the family Muscicapidae whose distributions overlap in Central and Eastern Europe and on the islands of Gotland and Oland in the Baltic Sea. Expand
