| a conceptual framework for the colonisation of urban areas: the blackbird turdus merula as a case study. | despite increasing interest in urban ecology the factors limiting the colonisation of towns and cities by species from rural areas are poorly understood. this is largely due to the lack of a detailed conceptual framework for this urbanisation process, and of sufficient case studies. here, we develop such a framework. this draws upon a wide range of ecological and evolutionary theory and the increasing number of studies of how the markedly divergent conditions in urban and rural areas influence t ... | 2010 | 20128785 |
| sarcocystis calchasi is distinct to sarcocystis columbae sp. nov. from the wood pigeon (columba palumbus) and sarcocystis sp. from the sparrowhawk (accipiter nisus). | sarcocystis calchasi has been identified as causative agent of a newly discovered central nervous disease in domestic pigeons (columba livia f. domestica) observed for the first time in germany in 2006. initial studies have indicated that this parasite is highly pathogenic for domestic pigeons after ingestion of low doses of sporocysts shed by the northern goshawk (accipiter gentilis). here we tested whether phylogenetically related birds might regularly harbor sarcocystis species. five wood pig ... | 2010 | 20381254 |
| an adaptive annual rhythm in the sex of first pigeon eggs. | when the reproductive value of male and female offspring varies differentially, parents are predicted to adjust the sex ratio of their offspring to maximize their fitness (trivers and willard, science 179:90-92, 1973). two factors have been repeatedly linked to skews in avian offspring sex ratio. first, laying date can affect offspring sex ratio when the sexes differ in age of first reproduction, such that the more slowly maturing sex is overproduced early in the season. second, position of the ... | 2010 | 20730075 |
| high prevalence of sarcocystis calchasi sporocysts in european accipiter hawks. | the emerging sarcocystis calchasi induces a severe and lethal central nervous disease in its intermediate host, the domestic pigeon (columba livia f. domestica). experimental studies have identified the northern goshawk (accipiter g. gentilis) as final host. phylogenetically closely related european sparrowhawks (accipiter n. nisus) and wood pigeons (columba palumbus) have been found to harbor genetically closely related sarcocystis spp. however, data on the prevalence and potential interspecies ... | 2010 | 21074324 |

| natural bagaza virus infection in game birds in southern spain. | in late summer 2010 a mosquito born flavivirus not previously reported in europe called bagaza virus (bagv) caused high mortality in red-legged partridges (alectoris rufa) and ring-necked pheasants (phasianus colchicus). we studied clinical findings, lesions and viral antigen distribution in naturally bagv infected game birds in order to understand the apparently higher impact on red-legged partridges. the disease induced neurologic signs in the two galliform species and, to a lesser extent, in ... | 2012 | 22966904 |
| genetic characterization of oropharyngeal trichomonad isolates from wild birds indicates that genotype is associated with host species, diet and presence of pathognomonic lesions. | oropharyngeal trichomonad isolates of wild birds from spain were studied. a total of 1688 samples (1214 of predator birds and 474 of prey species) from wildlife recovery centres and scientific bird-ringing campaigns were analysed from 2011 to 2013. the overall infection prevalence was 20.3% (11.4% in predator birds and 43.3% in prey species). pathognomonic lesions were present in 26% of the infected birds (57.3% in predator birds and 4.9% in prey species). the most commonly parasitized species w ... | 2014 | 25262786 |
| trichomonad parasite infection in four species of columbidae in the uk. | trichomonas gallinae is an emerging pathogen in wild birds, linked to recent declines in finch (fringillidae) populations across europe. globally, the main hosts for this parasite are species of columbidae (doves and pigeons); here we carry out the first investigation into the presence and incidence of trichomonas in four species of columbidae in the uk, through live sampling of wild-caught birds and subsequent pcr. we report the first known uk cases of trichomonas infection in 86% of european t ... | 2013 | 23866933 |
| goshawk prey have more bacteria than non-prey. | 1. predators often prey on individuals that are sick or otherwise weakened. although previous studies have shown higher abundance of parasites in prey, whether prey have elevated loads of micro-organisms remains to be determined. 2. we quantified the abundance of bacteria and fungi on feathers of woodpigeons columba palumbus l., jays garrulus glandarius l. and blackbirds turdus merula l. that either fell prey to goshawks accipiter gentilis l. or were not depredated. 3. we found an almost three-f ... | 2012 | 22039986 |
| viability selection on prey morphology by a generalist predator. | prey use their locomotory capacity to escape predators, and there should thus be strong viability selection on locomotory morphology of prey. we compared feather morphology of wood pigeons columba palumbus killed by goshawks accipiter gentilis with that of survivors to quantify directional and quadratic selection on primary and rectrix feathers. the goshawk is mainly a predator attacking by surprise, leaving wood pigeons with an ability to accelerate fast at a selective advantage. there was dire ... | 2009 | 19344382 |
| focal bird species and risk assessment approach for nonagricultural grassland scenarios in central europe. | the european food safety authority (efsa) guideline on risk assessment identifies pesticide exposure scenarios for nontarget wildlife; however, this scheme is not applicable to nonagricultural grassland. for example, different habitats and human utilization on golf courses attract bird communities that differ from those found in agricultural fields with annual crop cycles. the present study determined focal bird species for amenity grasslands such as golf courses following the efsa guideline. ba ... | 2014 | 24889926 |
| improving the persistence of a formulation of the avian repellent cinnamamide, for the protection of autumn-sown oilseed rape. | in a previous pilot field trial on autumn-sown oilseed rape (brassica napus l), a suspension concentrate formulation of the avian repellent cinnamamide, using acronal 4d (50 g litre(-1)) as the sticker, was shown to reduce damage by woodpigeons (columba palumbus l). however, the persistence of cinnamamide on rape leaves was poor. this paper describes the development of a weather-resistant formulation by the inclusion of a more effective sticker. in vitro studies were used to investigate wash-off ... | 2004 | 15481829 |
| field evidence of bird poisonings by imidacloprid-treated seeds: a review of incidents reported by the french sagir network from 1995 to 2014. | the large-scale use of neonicotinoid insecticides has raised growing concerns about their potential adverse effects on farmland birds, and more generally on biodiversity. imidacloprid, the first neonicotinoid commercialized, has been identified as posing a risk for seed-eating birds when it is used as seed treatment of some crops since the consumption of a few dressed seeds could cause mortality. but evidence of direct effects in the field is lacking. here, we reviewed the 103 wildlife mortality ... | 2017 | 28028702 |
| manipulation of primary sex ratio in birds: lessons from the homing pigeon (columba livia domestica). | across various animal taxa not only the secondary sex ratio but also the primary sex ratio (at conception) shows significant deviations from the expected equal proportions of sons and daughters. birds are especially intriguing to study this phenomenon as avian females are the heterogametic sex (zw); therefore sex determination might be under direct control of the mother. avian sex ratios vary in relation to environmental or maternal condition, which can also affect the production of maternal ste ... | 2013 | 23720529 |
| appropriate exposure estimates for wildlife risk assessments of crop protection products based on continuous radio telemetry: a case study with woodpigeons. | the registration of pesticides follows guidance published by the european food safety authority (efsa). as a default, the efsa guidance document on risk assessment for birds and mammals assumes that animals feed exclusively on pesticide-treated fields. however, the guidance document suggests refining the risk via the proportion of food animals obtain from a treated field or specific crop (expressed via the portion of diet obtained from a treated area [pt value]). the efsa guidance equalizes the ... | 2016 | 27753137 |
| effects of human disturbance on nest placement of the woodpigeon (columba palumbus): a case study from the middle atlas, morocco. | the woodpigeon (columba palumbus) is a common and widespread bird in morocco (north africa). i examined, over 2 years (2010 and 2011), the breeding density and nest placement of this game species in relation to nest site habitat and degree of human disturbance. the study area was in the middle atlas tighboula mountain forest, morocco, in a disturbed and an undisturbed site. using data collected in the 2 study sites, i aimed to identify the factors influencing the placement of nests within holm o ... | 2014 | 24148611 |
