Genetic studies have shown that extra-pair paternity is widespread among socially monogamous bird species. Yet, the role of males and females and their behavior leading to this mixed reproductive strategy is poorly understood. Here, we analyze p[...]

At St Kilda, Outer Hebrides, a large colony of great skuas Stercorarius skua feed extensively on one of the largest colonies of Leach's storm-petrels Oceanodroma leucorhoa in Europe, but little is known about the dynamics of this predator-prey s[...]

The evolutionary history of three out of four birds traditionally classified into the genus Rhodopechys birds has been studied by comparing their mitochondrial cytochrome b DNA sequence with that of greenfinches and other genus Carduelis finches[...]

The steroid hormone testosterone (T) mediates the expression of many secondary sexual characters, including behaviors which influence male reproductive success. Testes are one of the major sources of androgens, in particular of T. Although a pos[...]

We studied factors affecting breeding habitat selection in a population of cliff-nesting peregrines Falco peregrines across multiple spatial levels (cliff site, cliff context and land-use of the surrounding landscape), over a 2,100 km(2) study a[...]

I propose a methodology to obtain and compare integral information on bird plumage coloration, using colour spectral data to conduct studies on geographic variation and taxonomy of different bird groups. I used principal component analysis and d[...]

Intake rate, the rate in which herbivores can process their food, is presumed to be an important factor in habitat selection down to the scale of the foraging patch. Much attention has been given to the selection of swards of high nutritional qu[...]

We examined the effect of prey type, repeated stomach flushing, digestion time, and meal size on the assessment of dietary intake of captive adult Cory's shearwaters (Calonectris diomedea). For each of Cory's shearwaters' main prey type (fish, c[...]

Plumage colour has always been a major criterion when describing and distinguishing bird taxa. Today, the use of reflection spectrophotometry is the most commonly used technique to study plumage coloration. A major advantage of this method is th[...]

We have tested our assumption that infrasound from flutter jumps of displaying cocks is significant for capercaillie (Tetrao urogallus) orientation. Seven captive females were used for playback experiments during a period when they were extremel[...]

In territorial species, habitat heterogeneity results in some individuals occupying poor quality sites while others occupy high quality sites. Floaters (mature nonbreeders) may accept a low quality territory, because it is the best they can get [...]

Gene transfer may occur following hybridization between closely related species if hybrids are viable and able to breed with individuals of one or both of the parental species. House (Passer domesticus) and tree sparrows (P. montanus) occasional[...]

We studied variations in diet composition in sub-populations of mainland citril finches Carduelis [citrinella] citrinella in European mountain chains, compared to closely related insular Corsican (citril) finches Carduelis [citrinella] corsicanu[...]

Based on automated weighing of nest-boxes, we found that female great tits (Parus major) usually maintained their body mass during the egg-laying period. A drop in temperature (3 degrees C or more) during laying was followed by a drop in body ma[...]

The patterns of alpha-diversity and the structure and organisation of breeding bird assemblages were studied in four vegetation stages (characteristic of Mediterranean shrublands) on an eastern Mediterranean island (Crete, Greece): low phrygana,[...]
