Hybridization and adaptive mate choice in flycatchers
Article Abstract:
Research into hybridization in flycatchers is discussed. It is shown that collared and pied flycatchers have mechanisms which reduce the usual costs of hybridization, and mean that hybrid mating can be adaptive mate choice.

Trade-offs between life-history traits and a secondary sexual character in male collared flycatchers
Article Abstract:
A manipulation of the male Ficedula albicollis' parental effort by changing the number of offsprings occupying their nests showed a trade-off between parental effort and the size of the male collared flycatcher's forehead patch after one year. The size of the forehead patch in first-year males is found to be negatively related to the change in brood size of the nest where they were brought up. Results support the idea that life-history consequences of the male collared flycatcher's sexual ornaments are necessary to the animal's evolution.

A sexually selected character displacement in flycatchers reinforces premating isolation
Article Abstract:
Recent research focusing on the European, black-and-white 'Ficedula' flycatcher has attempted to test the theory that natural selection against the production of unhealthy hybrids may strengthen obstacles to gene flow. It was found that in flycatcher populations where there are two species living together, female choice focuses on a divergence in male plumage colour. The incidence of hybridization is reduced by the resulting character displacement. It can be shown that ongoing speciation takes place by reinforcement of premating isolation in sympatric pied and collared flycatchers.
