We describe a case of winter mass mortality of Eurasian Siskins Carduelis spinus caused by large road salt grains that birds apparently had mistaken for potential gizzard stones (gastroliths). Clinical evidence revealed acute salt intoxication a[...]

Nuptial ornament diversity was studied in 1814 individual male Ruffs that were caught in their spring staging areas in Friesland, The Netherlands. Ornaments (hereafter called plumages) comprised of a ruff, two head tufts and facial wattles. Indi[...]

In farmland in central Honshu, Japan, conspecific infanticide was recorded in five out of 68 breeding attempts of Eurasian Tree Sparrow Passer montanus in 2011 and 2012 including one suspected case. The number of eggs lost by infanticide account[...]

Mixed interspecific broods in hole nesting passerines occasionally occur as a by-product of competitive interactions for nest sites. Here, we report a rare case where such interactions led to a three species brood of Pied Flycatcher Ficedula hyp[...]

Colour morph variation is widely observed in owls and several studies have described differences in life history traits among the morphs. Traditionally, Glaucidium owls are described as having two colour morphs, rufous and grey, which are suppos[...]

Predation is a major cause of breeding failure in bird species with open nests. Although many studies have investigated nest predation rates, direct identification of nest predators is sporadic, especially in (semi-)natural habitats. We quantifi[...]

The main aim of this study was to investigate which weather parameter has greater influence on nest abandonment in the Great Tit Parus major, temperature or rain, and to determine during which breeding period nests are the most susceptible to ab[...]

Competition for nesting territory has been shown to act as a density-dependent feedback mechanism influencing population growth rate. However, little is known about the nature of territorial interactions between established breeders and floaters[...]

Birds consider both variation in prey abundance and accessibility in their decision of where to forage. Acidification and nitrogen deposition affect both prey abundance and accessibility by stimulating growth of nitrophilic grasses at the expens[...]

Birds inhabiting urban areas have to cope with novel conditions. Unlike natural habitats, birds in urban environments are exposed to an increased human presence which often induces stress. Urban birds with reduced sensitivity to human disturbanc[...]

Greenshanks Tringa nebularia show various patterns of primary moult in the northern hemisphere, but farther south moult patterns are known only fragmentarily. We identified geographical patterns in primary moult and pre-migratory fattening of Gr[...]

Weather and habitat-use are key factors that influence the survival of a species. A central goal in conservation biology is to gain a mechanistic understanding of how these quantities limit a species' range. We examined how weather, season and g[...]
