Several studies have shown considerably poorer breeding success of Great Tit Parus major populations in northern Finland than in mid- and western Europe. The aim of this study was to find out whether the poor success is linked to physiological c[...]

A new species and genus of a passerine bird from the early Oligocene of Poland is described. Resoviaornis jamrozi gen. et sp. nov. is the third nearly complete passerine known so far from the Paleogene. As in the two recently described passerine[...]

Central Europe has the responsibility to protect the Red Kite Milvus milvus as it holds the majority (> 50 % of all breeding pairs) of the global population. This entails the need for comprehensive knowledge of the birds' ecology and distributio[...]

Several factors promote coloniality by enhancing the fitness of colony members. In birds, spatial proximity among nests, breeder abundance and reproductive synchrony have been proposed as primary factors responsible for enhanced colonial defence[...]

We present new insights into the phylogeography of the Robin, Erithacus rubecula, from the seven Azores Islands where it breeds, based on sequences of mitochondrial and nuclear genes from 35 individuals (five from each of the seven islands) as w[...]

Measures of seabird breeding success are often used as bio-indicators for the state of the marine environment. For many seabirds, productivity is estimated by averaging data from a number of survey plots. This may lead to evidence of change bein[...]

Among the most eye-catching traits of avian eggs are their background coloration and pigmentation, consisting in many passerine birds of dark protoporphyrin spots. Although variation in protoporphyrin pigmentation among clutches has been shown t[...]

Species that exhibit intraspecific variation in migratory behavior provide a valuable opportunity to study the evolution of avian migration. The Northern Boobook (Ninox japonica) has two subspecies in East Asia, one sedentary (N. j. totogo) and [...]
