Carduelis; Emberiza; Vanellus; agricultural land; arable soils; birds; intensive farming; monitoring; Czech Republic
Abstract:
... The relationship between agricultural intensification and a decline in farmland bird populations is well documented in Europe, but the results are mostly based on data from the western part of the continent. In the former socialist eastern and central European countries, political changes around 1990 resulted in a steep decline in the intensity of agriculture. Therefore, one would expect populatio ...

Abstract:
... Determination of fitness differentials between individuals adopting different migratory and dispersal strategies is basic to understand the evolution of migration. In the Eurasian siskin Carduelis spinus, both resident and transient birds forage within the same wintering area, providing the rare opportunity to compare their foraging behaviour in the same area and habitat. The aim of this study was ...

Abstract:
... Collision with vehicles is an important source of bird mortality, but it is uncertain why some species are killed more often than others. Focusing on passerines, we tested whether mortality is associated with bird abundances, and with traits reflecting flight manoeuvrability, habitat, diet, and foraging and social behaviours. We also tested whether the species most vulnerable to road-killing were ...

Abstract:
... The decline of farmland birds across Europe is a well‐documented case of biodiversity loss, and despite land stewardship supported by funding from agri‐environment schemes (AES), the negative trends have not yet been reversed. To investigate the contribution of AES towards farmland bird conservation, we compared abundance of five farmland bird species across 13 years and 53 farms (158 farm years = ...

Abstract:
... Analysis of a banded population of American Goldfinches (Carduelis tristis) showed that frequencies of recaptured birds wearing at least one of nine different colored leg bands did not differ from expected frequencies over a 6-yr period. In a similar analysis, the likelihood of a bird becoming part of a local breeding population over a 4-yr period was independent of the color of its bands. For nin ...

Abstract:
... 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 desert finch (Rhodopechys obsoleta) or a sister extinct species seems to have existed about 6 million years ago in Asian and perhaps African desert-l ...

Abstract:
... Most animals must cope with seasonal fluctuations in environmental conditions, including variations in food availability and composition. Accordingly, it is expected that most species should exhibit reversible seasonal phenotypic adjustments in their physiology. Here, we assessed seasonal variation in the activity of three digestive enzymes (sucrase, maltase, and aminopeptidase-N) in one omnivioro ...

Abstract:
... Birds use change in daylength during the year to time events during their annual cycles. Individual Eurasian siskins Carduelis spinus can breed and winter in widely separated areas in different years. Birds at different latitudes will experience different changes in photoperiod. So how does latitude affect photoperiodic control? Our aim in this study was to find whether Siskins caught from the wil ...

35. Sex-specific aggression and sex ratio in wintering finch flocks: serins and siskins differ

Abstract:
... Males are dominant over females in many bird species. This may lead to male monopolisation of resources whenever food is scarce or clumped and secondarily to lower female survival rates. As a result of the consequent male-biased sex ratio in the adult population, competition may arise either (1) between males and females, as males attempt to exclude females from feeding patches, or (2) between mal ...

Abstract:
... Winter bird activity on 18 fields of a split conventional/organic farm in northern England was surveyed in six winters between 2002 and 2009. The three winter covers on the 10 conventional fields were grass, cereals (winter wheat and barley) and oilseed rape whilst grass/clover, cereal stubble (wheat) and vegetable stubbles (beans, potatoes, Brassicas) covered the eight organic fields. The fields ...

Abstract:
... In many avian species, it has been well demonstrated that individuals attempting to breed in harsh or unpredictable environments always express reduced adrenocortical responses to acute stress, whereas those breeding in more benign or predictable environments may show more robust responses. However, fewer studies have focused on comparing closely related species that express similar behavioral tra ...

Particularly, the phylogenetic relationships between muscicapoidea and sylvioidea are complex, and their taxonomic boundaries have not been clearly defined. Our aim was to study the status of two bird species: Tarsiger cyanurus and Phoenicurus auror ...

Abstract:
... Avian haemosporidian parasites of the genus Haemoproteus (Haemoproteidae, Haemosporida) are widespread, and some species cause diseases both in vertebrate hosts and blood-sucking insects. Parasitemia of Haemoproteus species usually is long-lasting, with gametocytes present in the circulation for several months. However, the viability of gametocytes and their ability to produce sexual cells have be ...
