Data from: No fitness benefits of early molt in a fairy-wren: relaxed sexual selection under genetic monogamy?

Marie Fan, Michelle L. Hall, Sjouke A. Kingma, Lisa M. Mandeltort, Nataly Hidalgo Aranzamendi, Kaspar Delhey & Anne Peters
The evolution of male ornamentation has long been the focus of sexual selection studies. However, evidence is accumulating that sexually selected traits can also be lost, although the process is ill-understood. In male fairy-wrens (Malurus spp.), early molt into the seasonal breeding plumage is critical for obtaining extra-pair paternity (EPP), which reaches very high levels in these socially monogamous songbirds. A notable exception is the purple-crowned fairy-wren, Malurus coronatus, which, like its congeners, breeds cooperatively,...

Data from: Higher songs of city birds may not be an individual response to noise

Sue Anne Zollinger, Peter J. B. Slater, Erwin Nemeth & Henrik Brumm
It has been observed in many songbird species that populations in noisy urban areas sing with a higher minimum frequency than do matched populations in quieter, less developed areas. However, why and how this divergence occurs is not yet understood. We experimentally tested whether chronic noise exposure during vocal learning results in songs with higher minimum frequencies in great tits (Parus major), the first species for which a correlation between anthropogenic noise and song frequency...

Data from: Admixture between released and wild game birds: a changing genetic landscape in European mallards (Anas platyrhynchos)

Pär Söderquist, Johan Elmberg, Gunnar Gunnarsson, Carl-Gustaf Thulin, Jocelyn Champagnon, Matthieu Guillemain, Jakub Kreisinger, Herbert H. T. Prins, Richard P. M. A. Crooijmans & Robert H. S. Kraus
Disruption of naturally evolved spatial patterns of genetic variation and local adaptations is a growing concern in wildlife management and conservation. During the last decade, releases of native taxa with potentially non-native genotypes have received increased attention. This has mostly concerned conservation programs, but releases are also widely carried out to boost harvest opportunities. The mallard, Anas platyrhynchos, is one of few terrestrial migratory vertebrates subjected to large-scale releases for hunting purposes. It is the...

Data from: Social and spatial effects on genetic variation between foraging flocks in a wild bird population

Reinder Radersma, Colin J. Garroway, Anna W. Santure, Isabelle De Cauwer, Damien R. Farine, Jon Slate & Ben C. Sheldon
Social interactions are rarely random. In some instances animals exhibit homophily or heterophily, the tendency to interact with similar or dissimilar conspecifics respectively. Genetic homophily and heterophily influence the evolutionary dynamics of populations, because they potentially affect sexual and social selection. Here we investigate the link between social interactions and allele frequencies in foraging flocks of great tits (Parus major) over three consecutive years. We constructed co-occurrence networks which explicitly described the splitting and merging...
