Evolution and expression of genetic variation in nestling traits

Collared Flycatcher (Ficedula albicollis) Science Article 2 abstract Environmental conditions experienced during early life are known to impact upon the development of passerinenestlings, as well as on their performance and fitness as adults. Nevertheless, little is yet known about the relative importanceof different types of maternal, environmental and genetic effects as proximate determinants of variation […]

Availability and use of public information and conspecific density for settlement decisions in the collared flycatcher

Collared Flycatcher (Ficedula albicollis) Science Article 4 abstract Public information, i.e. local reproductive performance of conspecifics, is expected to be a highly valuable cue for breeding habitat selection. However, the access to this cue may be spatially and temporally constrained. When public information is unavailable, individuals may use other integrative cues, such as the local […]

Reproductive investment and moult-breeding overlap in the collared flycatcher Ficedula albicollis: an experimental approach

Collared Flycatcher (Ficedula albicollis) Science Article 1 abstract We manipulated brood sizes of 132 pairs of the collared flycatcher to investigate whether or not an investment in reproduction was traded against an investment and timing of the post-nuptial moult. Our manipulations did not affect the probability of moult-breeding overlap in males, and there was no […]

Immune challenge mediates vocal communication in a passerine bird: an experiment

Collared Flycatcher (Ficedula albicollis) Science Article 3 abstract Secondary sexual characters may have evolved in part to signal resistance to parasites. Avian song has been hypothesized to be involved in this process, but the role of parasites in modulating acoustic communication systems in birds remains largely unknown, owing to lack of experiments. We studied the […]
