Territory fidelity defines a process in which individuals reoccupy a territory during different reproductive periods. In this study, we used generalized linear mixed models to analyse the territory fidelity of the Booted Eagle Hieraaetus pennatu[...]

Nest-site selection can be an important pre-emptive defense strategy for songbirds to reduce the risk of predation and is likely most effective when it incorporates both public and private information about predation. We examined the degree to w[...]

Using nest boxes with different sized entrances, we experimentally examined whether a large species of cavity breeder (House Sparrow, Passer domesticus) affects the nest box occupancy and breeding success of a smaller species (Great, Tit, Parus [...]

Five breeding groups of the Alpine Accentor were studied in a Swiss alpine region. The studied groups showed a polygynandrous mating system and each group was formed of 1-4 females and 3-5 males. The females had exclusive territories, while the [...]

We investigated how habitat-specific differences in behavioural patterns affected Brent Goose energetics along a feeding continuum from natural aquatic to inland agricultural habitats. Time-budgets showed that geese using salt-marshes and inland[...]

Changes in flight muscle size are important mediators of phenotypic flexibility in birds, so the ability to track such changes over time in individual birds is a valuable tool for investigating phenotypic flexibility. Ultrasonography has been us[...]

Many species of tropical birds have prolonged incubation periods compared to other tropical species and to most species in temperate latitudes. One hypothesis for prolonged incubation is that these tropical species reduce nest attendance to mini[...]

Life history theory predicts that parents will not raise unrelated offspring. For seabirds, an ability to recognize their own eggs and chicks can prevent a costly mistake. We tested whether Magellanic Penguins (Spheniscus magellanicus) would dis[...]

It is well documented that sperm size and structure varies considerably among avian species, but we know much less about the extent of intraspecific variation in sperm morphometry and its possible co-variation with somatic traits like body size [...]

Detailed information is still lacking on structure and duration of calls of diurnal birds of prey as well on their vocal repertoire. The Lanner Falcon (Falco biarmicus) is considered a shy less-vociferous species but no quantitative data exist. [...]

Migratory routes and stopover sites used by migrant landbirds may vary among seasons and years. Understanding the degree of such variation is an important aspect of migrant ecology, especially in South America, where routes and sites are not wel[...]

Despite the high biodiversity that characterizes the tropics, we know little about the behaviour of most tropical birds. Antbirds (Thamnophilidae) are a biodiverse family of more than 200 species found throughout Central and South America, yet t[...]

Sex allocation theory explains how parents should allocate reproductive effort to the rearing of sons and daughters. A central premise is that there is room for individual optimization of brood sex ratios as a function of the relative rearing co[...]

There is much evidence to support past contact between the Atlantic and the Amazon forests through the South American dry vegetation diagonal, but the spatiotemporal dynamics of this contact still need to be investigated to allow a better unders[...]

In raptors, brood size seems to be closely related to the size of prey brought to the nest, the delivery rate and the degree of parental effort. In the case of Peregrine Falcons (Falco peregrinus), any increase in the size of prey is considered [...]

The endozoochorous dispersal of weed seeds, mediated by birds and without any adaptation to frugivory, has been studied very rarely. We studied the endozoochorous dispersal of viable seeds by the grey partridge Perdix perdix in agricultural land[...]
