Climate change is causing phenological shifts in the environment. Among birds, increasing temperatures have been shown to advance the spring migration and breeding, which in turn affect individual reproductive success. The autumn migration pheno[...]

Male song is known to be important in the mate choice of birds, as different song features reflect different traits of the singer. The reason why song complexity, in this context, should reflect the quality of the performing individual is still [...]

I designed two experiments to evaluate how polygyny is achieved in Southern House Wrens (Troglodytes aedon inusculus) breeding in a south-temperate population. In the first experiment, I manipulated territory attractiveness by adding high qualit[...]

During the breeding season, Pied Avocets, Recurvirostra avosetta, produce five morphologically distinct syllables-chuck, chirp, whistle, coo and snarl-which form the basis of the species' adult vocal repertoire. Chuck, chirp and whistle each con[...]

A mechanistic understanding of species' geographic range dynamics requires an understanding of the dynamics of populations at the eke of that range. Several ibis species are currently expanding their ranges, and the Hadeda Ibis (Bostrychia haged[...]

Sexual dimorphism is often associated with different feeding strategies between sexes because of distinct nutritional demands or intake rates. Capercaillie (Tetrao urogallus) is the most sexually dimorphic grouse, thus sexual segregation in reso[...]

Males in many bird species develop elaborate carotenoid-based plumage ornaments which often play an important role as signals of individual quality in intra- or intersexual selection. However, knowledge of the pattern of age-related variation in[...]

In song-learning birds, male song shows a large inter-individual variation that frequently plays an important role in intra- and inter-sexual selection. In other bird groups, such as Galliformes, song learning is absent, and inter-individual son[...]

Skylarks (Alauda arvensis) are known to adopt a typical aggregative behaviour during the wintering period. A further benefit is that individuals in larger groups can decrease the amount of time they spent being vigilant, while maintaining a high[...]

In theory, obligate brood parasitic birds are freed from several of the temporal and spatial constraints of parental care for dependent young. Yet, similar to parental bird species, adults in several avian brood parasites show a territorial spac[...]
