Do Tengmalm's Owls alter parental feeding effort under varying conditions of main prey availability?
Markéta Zárybnická, Auteur ;
Ondřej Sedláček, Auteur ;
Erkki Korpimäki, Auteur
We studied the diet composition and behavioural responses to variable food conditions in Tengmalm's Owls (Aegolius funereus). The abundance of main prey (voles and mice) of owls was higher in the Ore Mountains, Czech Republic, than in the Kauhav[...]

We studied the reproductive success of a wild Lesser Rhea population (Pterocnemia -Rhea- pennata pennata) during two reproductive seasons (2004/2005 and 2005/2006) in north-western Patagonia, Argentina. The parameters recorded included populatio[...]

Methods of evaluating population trends have recently received particular attention because of perceived declines in several species during the twentieth century. We have studied demographic traits of the peregrine falcon (Falco peregrinus) popu[...]

Juveniles of many birds establish dominance hierarchies within family social units, only to leave and compete to acquire dominance status in new social groups. Little is known about the role of sex, body mass, size or experience during the duckl[...]

The yellowhammer Emberiza citrinella is a common European bird that sings in dialects that for decades have been distinguished by the existence of one single element (called a "specific''). In this study we looked into other possibilities for di[...]

Despite a long historical record of radio-tracking analyses, basic home-range information is still lacking for most common waterfowl species, especially during the winter. We investigated how dabbling duck home ranges and daily foraging movement[...]

Using eggshell membranes as a non-invasive tool to investigate the source of nutrients in avian eggs
Steffen Oppel, Auteur ;
Abby N. Powell, Auteur ;
Diane M. O'Brien, Auteur
Development of minimally invasive techniques to collect nutritional information from free-living birds is desirable for both ethical and conservation reasons. Here, we explore the utility of waterfowl eggshell membranes to determine the nutrient[...]

Two frequent assumptions about the evolution of long-distance migration in birds are that they travel long distances annually to reach food-rich areas for breeding, and that they time their migratory journey to be at staging sites when the latte[...]

Periodic censuses have been widely used to identify the population numbers and conservation status of many bird species. In order to be comparable, a census must be homogeneous through time. However, this requirement is not always possible. For [...]

Brood-guarding (or the continual attendance at the nest by one parent) has been relatively little studied in altricial birds. Parental investment in brood-guarding is often highly variable within a species, and the study of such variability may [...]

Black-tailed (Limosa limosa) and Hudsonian Godwits (L. haemastica) are sometimes described as a superspecies. The Black-tailed Godwit is further split into three subspecies on the basis of morphological differences ( L. l. limosa, L. l. islandic[...]

We examined long-term responses in the breeding performance of the Great Reed Warblers Acrocephalus arundinaceus to climate change. The study took place in various years from 1970 to 2007. During the study period, mean temperatures in the breedi[...]

The "reverse migration hypothesis'' as the explanation for the vagrancy of Far Eastern birds in Europe is commented on. It is concluded that, as the postulated switch of 180 degrees along a great circle line would lead the eastern or even centra[...]

The breeding biology of the endemic Coquerel's Coua (Coua coquereli), a non-parasitic cuckoo species for which few ecological data are available, was studied in the dry deciduous forest of western Madagascar. Nestling C. coquereli remain in the [...]

The brood parasitic habits of the European Cuckoo Cuculus canorus have excited wonder, disbelief and speculation since the fourth century BC. Accurate knowledge of cuckoo biology, however, accumulated only slowly and mostly since 1700. The aim o[...]

Many bird species adjust their offspring sex ratio as a response to environmental conditions or sexual dimorphism in size and dispersal. Offspring sex ratios may therefore vary among populations depending on the different demographic and ecologi[...]
