Determining the functional significance of ornamental traits and whether they are shaped by sexual selection requires understanding how they vary among individuals, and their relationship with other measures of quality. Conspicuous eggshell colo[...]

Lesser kestrel males display inter-individual variation in melanin-based plumage traits, like ventral plumage colouration and breast/underwing spottiness. We explored whether such plumage variability was associated with single-nucleotide genetic[...]

Increasing rates of nest predation is one of several hypotheses proposed to explain observed declines of Wood Warbler Phylloscopus sibilatrix populations in the UK. Nest predation may be influenced by how nest concealment is affected by vegetati[...]

Delayed plumage maturation occurs in birds when subadult plumage is retained until after the first breeding season. We analysed data from 114 Black Wheatears (Oenanthe leucura), which were trapped during 2014–2016 in southeastern Spain, to explo[...]

Following its eradication in the Alps in the early 1900s, the Bearded Vulture Gypaetus barbatus has been reintroduced in four Alpine regions since 1986. The first successful breeding since this reintroduction into the wild occurred in 1997 in th[...]

Fighting and flirting are the main evolutionary forces behind the development of bird song and both contribute to different song characteristics. By comparison of vocalisations throughout bird taxa, we can help to reconstruct the evolutionary hi[...]

A large part of the variation in bird reproductive success is often explained by nest predation. Many studies report negative relationships between breeding density and reproductive success due to the predation effect. In this study, we tested t[...]
