West Nile virus (WNV) is a mosquito-borne Flavivirus with birds as its natural reservoir. Mosquitoes are able to transmit WNV to humans. In Europe, WNV is most probably imported by migrating birds from WNV-endemic regions. In this study, the ris[...]

A complete tarsometatarsus of a passerine bird from the early Miocene (MN 3) of Petersbuch (Bavaria, Germany) is identified as an extinct representative of the climbing Certhioidea, i.e., a clade comprising treecreepers (Certhiidae), nuthatches [...]

The endangered Cantabrian capercaillie (Tetrao urogallus cantabricus) lives at the southern edge of tetraonids' distribution range, in entirely deciduous forests. Its conservation planning has been always lek-centred. There is very little inform[...]

We compared habitat use and diets of young Capercaillie and Black Grouse broods in a boreal forest in southeast Norway. We used pointing dogs to search for broods (N = 83) in mature "natural" forest types and examined the crop content of 66 chic[...]

Remote sensing data have been used in previous studies to assess the effects of winter ecological conditions in Africa on biological parameters recorded in bird populations during the following breeding season in Europe. Based on the results of [...]

The Lesser Rhea (Pterocnemia-Rhea-pennata pennata) has a complex reproductive system that combines polygyny with sequential polyandry, in which males build the nest, fully incubate the eggs and care for the young. As occurs with the Greater Rhea[...]

In Central Europe, massive losses in species richness of breeding birds have been documented in the last decades, but the question arises whether species richness is currently still decreasing or again increasing due to conservation efforts. In [...]

Tropical agroecosystems cover an increasingly large proportion of the Earth's terrestrial surface. Yet, relatively little is known about the factors that influence their avifauna, especially in areas of high human population density. The potenti[...]

In some species, corticosterone (CORT) appears to play a role in the control of begging behavior. Because of the potentially high costs associated with chronic elevation of CORT, it has also been proposed as a mechanism to ensure begging is an h[...]

The larvae of blow fly (Trypocalliphora braueri) are known to cause a subcutaneous myiasis in bird nestlings mainly in Nearctic species, while only a few records are available from the Palaearctic. Here, we report on infestations of this insect [...]

One hypothesized function of conspicuous mobbing of intruders by bird nest owners is to attract neighbouring birds ("calling for help" hypothesis) or third-party predators ("attract the mightier" hypothesis). These may help the nest owners by di[...]

This paper reports on the observation of an oilbird, Steatornis caripensis, in Peruvian lowland Amazonia in September 2006, and discusses this sighting in relation to other lowland reports of oilbirds. Taken together, available information indic[...]

This study aims to investigate causes and mechanisms controlling protandrous migration patterns (the earlier breeding area arrival of males relative to females) and inter-sexual differences in timing of migration in relation to the recent climat[...]

Stable carbon- (delta(13)C), nitrogen- (delta(15)N) and hydrogen (delta D) isotope profiles in feathers of migratory Great Reed Warblers Acrocephalus arundinaceus recaptured for 2 or more years in 6 successive years were examined to test whether[...]

Four non-exclusive hypotheses have been proposed to explain the alternative nest-building behaviour of raptors: (1) nests as an advertising signal in territories, (2) frustration nests, (3) competition avoidance by nest-site and (4) reduction of[...]

To investigate migratory connectivity in the Reed Warbler Acrocephalus scirpaceus, we analysed (1) all available sub-Saharan ringing recoveries and (2) stable isotopes in feathers grown in Africa sampled at 17 European breeding sites across a mi[...]

The effects of large-scale climatic phenomena on the timing of breeding in the Osprey Pandion haliaetus were studied during 1981-2006 in a small local population of about 20 pairs near the southern coast of Finland. The timing of breeding was es[...]
