Despite the capacity for dispersal, range size varies considerably among birds species. Many species have restricted geographic spread, whilst others routinely travel long distances to reach preferred habitat. These alternatives are well express[...]

Warming in the Arctic has caused the transition from winter to summer to occur weeks earlier over the last half century, yet little is known about whether avian migrants have altered their timing of arrival on breeding areas to match this earlie[...]

Many birds have advanced their spring migration and breeding phenology in response to climate change, yet some long-distance migrants appear constrained in their adjustments. In addition, bird species with long generation times and those in high[...]

Repertoire matching occurs when one songbird replies to another with a song type that the two birds share. Repertoire matching has previously been demonstrated to occur at well above chance levels in a western population of song sparrows, where [...]

Estimates of demographic parameters such as survival and reproductive success are critical for guiding management efforts focused on species of conservation concern. Unfortunately, reliable demographic parameters are difficult to obtain for any [...]

In birds parental incubation behaviour is an important factor shaping the environmental conditions under which the embryos develop, and sub-optimal incubation temperatures are known to negatively affect early growth and development. It is less w[...]

Carotenoid-based colouration in feathers is widely accepted to be a reliable signal of the health of an individual, but the condition-dependence of melanin-based plumage ornaments has been highly debated. Using broods that were manipulated in si[...]

The role of melanin badges of status', in male-male competition has been well-studied, in contrast, carotenoid based plumage has largely been examined in the context of female mate choice. Recent work has shown that carotenoid signals can also f[...]

The conservation of endangered taxa often critically depends on accurate taxonomic designations. The status of the Gran Canaria population of the blue chaffinch Fringilla teydea polatzeki has not been reevaluated since the early 1900s when this [...]

While considerable variations in both the frequency of extra-pair paternity (EPP) and the behavioral events that produce it are recognized among species, populations, individuals, and breeding attempts, the determinants of these variations are s[...]

Unlike the annual bi-directional movements of over 200 bird species within the Palaearctic-Afrotropical region, irregular movements such as irruptive migration with a low degree of philopatry are reported for a variety of species depending on hi[...]

We studied the phylogeography and population history of the white wagtail Motacilla alba, which has a vast breeding range, covering areas with different Pleistocene climatic histories. The mitochondrial NADH dehydrogenase subunit II gene (ND2) a[...]

The neophobia threshold hypothesis (NTH) suggests that the acquisition and maintenance of a high behavioral and ecological flexibility in the evolutionary and adaptive history of a species is the consequence of lower levels of neophobia towards [...]

The use of active chemical defence against predators is relatively rare in birds. Among others, it has been reported for some members of family Cuculidae whose chicks, when threatened, expel dark foul-smelling liquid from their cloaca. Apart fro[...]

Many bird species produce two annual broods during a single breeding season. However, not all individuals reproduce twice in the same year suggesting that double brooding is condition-dependent. In contrast to most raptors and owls, the barn owl[...]

The study of iridescent coloration in birds emerged only recently, mainly due to the difficulty inherent in quantifying its directionality. Directionality restrains color perception to a limited angle and thereby causes drastic changes in bright[...]
