Mercury (Hg) is a global pollutant that has wide-ranging impacts on the physiological systems of birds, but almost nothing is known about how this affects migration. We manipulated methylmercury (MeHg) burdens of 24 wild-caught Yellow-rumped War[...]

Worldwide, many wader species have recently exhibited steep declines in range and abundance. Low productivity, frequently associated with predation, is considered a major proximate driver of declines and often reflects underlying land use and ha[...]

Resource pulses are wide-ranging, influential ecosystem processes with effects permeating throughout the food web, sometimes over several years. In temperate forests, resource pulses may be triggered by mast seeding of one or several tree specie[...]

Animals are able to learn, remember, and make use of previous experiences when making decisions in similar situations, which are some of the most fascinating phenomena in behavioural ecology. However, these cognitive abilities can act as impedim[...]

Long-distance migrants with transcontinental breeding ranges are of particular interest for the study of local adaptation and geographic differentiation in birds. We compared phenotypes and genotypes between Far East Siberian Willow Warblers Phy[...]

The pre-laying exodus (PLE) is considered a crucial period in the breeding biology of Procellariiformes as it determines the success of egg production within a season and, therefore, a population’s reproductive output. However, it has scarcely b[...]

Several evolutionary processes seem to have influenced the Atlantic Forest (AF) biogeographic history, as suggested by phylogeographic studies that have shown a multitude of patterns. Here, we use approximate Bayesian computation to test alterna[...]

Bioacoustics is the study of animal sounds. The importance of bioacoustics for biological research and the survey and monitoring of bird populations is becoming increasingly recognized. This is particularly the case for the capture of long-term [...]

Vineyards are intensively managed monocultures, constituting homogeneously cultivated landscapes. They often have a mineral appearance, not only because they occur mostly in xeric biomes but also as a result of the herbicide treatments used to c[...]

Increasing light emissions caused by human activities have been recognized as a major threat for nocturnal animals. In Switzerland, the European Nightjar is a rare bird, decreasing in numbers since the 1970s, and is therefore highly threatened. [...]

Mountain habitats are threatened by several factors, including human activities at high elevation, although the negative impacts can sometimes be balanced by positive effects related to human presence. However, knowledge of such interactions is [...]

The timing of breeding in birds has important consequences if food availability varies seasonally. Optimal timing of the most energetically demanding stages of breeding to coincide with peaks in food availability can increase breeding success. E[...]

The Hyacinth Macaw (Anodorhynchus hyacinthinus) is a threatened species of the family Psittacidae. Its classification as vulnerable by the International Union for Conservation of Nature is especially a result of habitat loss and intense illegal [...]

Birds, like most animals, are expected to adjust their foraging activity in response to biotic and abiotic variations to optimize energy intake and reduce costs associated with finding and ingesting food. This may lead to temporal variation in t[...]

Stable isotope analyses can detect interactions between different stages of the annual cycle in migratory animals. We used carbon (δ13C), nitrogen (δ15N) and sulphur (δ34S) isotopes to identify non-breeding environments, the strategy of nutrient[...]

Stopover periods in between migratory flights determine the speed of migration and as such may affect birds’ fitness. The decision to leave a stopover site is affected by, for example, energy stores and weather conditions. We investigated whethe[...]

Many birds change their partners every year and pairing may occur before arrival on the breeding grounds. Early pairing strategies can benefit mates by strengthening pair-bonds and increasing the rate of pre-breeding resource acquisition, leadin[...]

Mobbing is an anti-predator strategy initiated by one or more members of prey species aiming at driving away a predator that is not undertaking an attack. Because of a continuous dispute as to whether mobbing of a top predator may indicate speci[...]

Land use changes in Europe have resulted in forest loss and fragmentation that have been proved to be key factors driving the decline of various forest bird populations. Quantifying the environmental factors which allow the persistence of forest[...]
