| seropositivity and risk factors associated with toxoplasma gondii infection in wild birds from spain. | toxoplasma gondii is a zoonotic intracellular protozoan parasite of worldwide distribution that infects many species of warm-blooded animals, including birds. to date, there is scant information about the seropositivity of t. gondii and the risk factors associated with t. gondii infection in wild bird populations. in the present study, t. gondii infection was evaluated on sera obtained from 1079 wild birds belonging to 56 species (including falconiformes (n = 610), strigiformes (n = 260), ciconi ... | 2011 | 22216311 |
| reference intervals for intraocular pressure measured by rebound tonometry in ten raptor species and factors affecting the intraocular pressure. | intraocular pressure (iop) was measured with the tonovet rebound tonometer in 10 raptor species, and possible factors affecting iop were investigated. a complete ophthalmic examination was performed, and iop was assessed in 2 positions, upright and dorsal recumbency, in 237 birds belonging to the families accipitridae, falconidae, strigidae, and tytonidae. mean iop values of healthy eyes were calculated for each species, and differences between families, species, age, sex, left and right eye, as ... | 2011 | 22216716 |
| characterization of fecal vancomycin-resistant enterococci with acquired and intrinsic resistance mechanisms in wild animals, spain. | the objectives were to evaluate the presence of vancomycin-resistant enterococci with acquired (vre-a) and intrinsic (vre-i) resistance mechanisms in fecal samples from different wild animals, and analyze their phenotypes and genotypes of antimicrobial resistance. a total of 348 cloacal/rectal samples from red-legged partridges (127), white storks (81), red kites (59), and wild boars (81) (june 2014/february 2015) were inoculated in slanetz-bartley agar supplemented with vancomycin (4 μg/ml). we ... | 2016 | 26194421 |
| wild birds, frequent carriers of extended-spectrum β-lactamase (esbl) producing escherichia coli of ctx-m and shv-12 types. | to get a better insight into the role of birds as reservoirs of extended-spectrum β-lactamase (esbl) and plasmidic ampc β-lactamase (pampc) escherichia coli producers, 100 fecal samples belonging to 15 different wild avian species from northern spain were analyzed. cefotaxime-resistant (ctx(r)) e. coli isolates were identified in 16 of the 100 tested birds, which corresponded to 9 animal species (gyps fulvus-griffon vulture, larus michahellis-yellow-legged gull, milvus migrans-black kite, milvus ... | 2016 | 26687342 |
| host-specific exposure and fatal neurologic disease in wild raptors from highly pathogenic avian influenza virus h5n1 during the 2006 outbreak in germany. | raptors may contract highly pathogenic avian influenza virus h5n1 by hunting or scavenging infected prey. however, natural h5n1 infection in raptors is rarely reported. therefore, we tested raptors found dead during an h5n1 outbreak in wild waterbirds in mecklenburg-western pomerania, germany, in 2006 for h5n1-associated disease. we tested 624 raptors of nine species-common buzzard (385), eurasian sparrowhawk (111), common kestrel (38), undetermined species of buzzard (36), white-tailed sea eagl ... | 2015 | 25879698 |
| molecular identification of traces from the white-tailed sea eagle. | over the preceeding decades, after periods of dramatic decline and extinction in many parts of europe, the white-tailed sea eagle (haliaeetus albicilla) has re-colonized traditional breeding areas. however, this large apex predator remains threatened, not only by the bioaccumulation of environmental pollutants, but also by targeted poisoning and poaching. in connection with a forensic case, a novel pcr assay was developed for the sensitive and specific detection of sea eagle dna traces in questi ... | 2013 | 22926772 |
| specialized photoreceptor composition in the raptor fovea. | the retinae of many bird species contain a depression with high photoreceptor density known as the fovea. many species of raptors have two foveae, a deep central fovea and a shallower temporal fovea. birds have six types of photoreceptors: rods, active in dim light, double cones that are thought to mediate achromatic discrimination, and four types of single cones mediating color vision. to maximize visual acuity, the fovea should only contain photoreceptors contributing to high-resolution vision ... | 2017 | 28199005 |
| ultraviolet sensitivity and colour vision in raptor foraging. | raptors have excellent vision, yet it is unclear how they use colour information. it has been suggested that raptors use ultraviolet (uv) reflections from vole urine to find good hunting grounds. in contrast, uv plumage colours in songbirds such as blue tits are assumed to be 'hidden' communication signals, inconspicuous to raptors. this ambiguity results from a lack of knowledge about raptor ocular media transmittance, which sets the limit for uv sensitivity. we measured ocular media transmitta ... | 2013 | 23785106 |
| monitoring agricultural rodenticide use and secondary exposure of raptors in scotland. | despite the documented risk of secondary poisoning to non-target species by anticoagulant rodenticides there is no statutory post-approval monitoring of their use in the uk. this paper presents results from two scottish monitoring schemes for the period 2000-2010; recording rodenticide use on arable farms and the presence of residues in raptor carcasses. more than three quarters of arable farms used anticoagulant rodenticides; predominately the second generation compounds difenacoum and bromadio ... | 2013 | 23595554 |
| sex determination in 58 bird species and evaluation of chd gene as a universal molecular marker in bird sexing. | the aim of this research was to test the chd gene (chromo helicase dna-binding gene) as a universal molecular marker for sexing birds of relatively distant species. the chd gene corresponds to the aim because of its high degree of conservation and different lengths in z and w chromosomes due to different intron sizes. dna was isolated from feathers and the amplification of the chd gene was performed with the following sets of polymerase chain reaction (pcr) primers: 2550f/2718r and p2/p8. sex de ... | 2015 | 22553188 |
| unintentional wildlife poisoning and proposals for sustainable management of rodents. | in europe, bromadiolone, an anticoagulant rodenticide authorized for plant protection, may be applied intensively in fields to control rodents. the high level of poisoning of wildlife that follows such treatments over large areas has been frequently reported. in france, bromadiolone has been used to control water voles (arvicola terrestris) since the 1980s. both regulation and practices of rodent control have evolved during the last 15 years to restrict the quantity of poisoned bait used by farm ... | 2014 | 24405288 |
| can ingestion of lead shot and poisons change population trends of three european birds: grey partridge, common buzzard, and red kite? | little is known about the magnitude of the effects of lead shot ingestion alone or combined with poisons (e.g., in bait or seeds/granules containing pesticides) on population size, growth, and extinction of non-waterbird avian species that ingest these substances. we used population models to create example scenarios demonstrating how changes in these parameters might affect three susceptible species: grey partridge (perdix perdix), common buzzard (buteo buteo), and red kite (milvus milvus). we ... | 2016 | 26799815 |
| scavenging of rodent carcasses following simulated mortality due to field applications of anticoagulant rodenticide. | worldwide, agricultural uses of anticoagulant rodenticides (ars) cause poisonings of non-target wildlife as observed in france where bromadiolone is used to control water vole outbreaks. following bromadiolone field application, a part of the vole population may die aboveground of the treated plots and thus, can represent an important risk of secondary poisoning for scavengers. in this study, water voles were trapped in a non-treated area and their carcasses were placed aboveground in plots loca ... | 2014 | 25147048 |
| variation in predator species abundance can cause variable selection pressure on warning signaling prey. | predation pressure is expected to drive visual warning signals to evolve toward conspicuousness. however, coloration of defended species varies tremendously and can at certain instances be considered as more camouflaged rather than conspicuous. recent theoretical studies suggest that the variation in signal conspicuousness can be caused by variation (within or between species) in predators' willingness to attack defended prey or by the broadness of the predators' signal generalization. if some o ... | 2012 | 22957197 |
| vigilance poison: illegal poisoning and lead intoxication are the main factors affecting avian scavenger survival in the pyrenees (france). | a specific surveillance program has been set up to monitor avian scavenger populations in the french pyrenean mountains, hosting a high proportion of the french populations. the two main purposes of the study were to identify all causes of death and to investigate poisoning cases. all 170 birds found dead during the 7-year program were submitted to full necropsy, x-ray, parasitological investigations and consistent analytical toxicology screenings (cholinesterase inhibitors, anticoagulant rodent ... | 2015 | 25913360 |
| fatal embryo chondral damage associated with fluoroquinolones in eggs of threatened avian scavengers. | stabled livestock reared in housed conditions are often subjected to intensive treatments with veterinary drug, which residues may be present in livestock meat ingested by scavengers, but nothing is known about their presence in eggs of wild birds and their potential detrimental effects on breeding success. we searched for residues of veterinary drugs and other toxicants in infertile and embryonated unhatched eggs of griffon vultures (gyps fulvus) and red kites (milvus milvus), two threatened av ... | 2009 | 19321243 |
| re-introduction of birds and mammals to the british isles. | large and exciting raptors like white-tailed eagle and red kite have been restored to the skies of scotland and england, and now there are advanced plans to return the beaver. these successes encourage debate on other missing animals, with the elusive eurasian lynx as the next best candidate. | 2003 | 12586953 |
| enantiomeric fractions and congener specific determination of polychlorinated biphenyls in eggs of predatory birds from doñana national park (spain). | the content of 30 polychlorinated biphenyls (pcbs) and the enantiomeric fractions of 10 chiral pcbs were determined in 17 infertile eggs from three different predatory bird species collected in doñana national park (dnp, spain) in the period 1999-2000. the highest pcb concentration was found in eggs from red kites (0.52-110 microg/g on a fresh weight basis, f.w.) followed by buzzard (0.08-13 microg/g f.w.) and booted eagle (0.10-1.5 microg/g f.w.). seventy-five percent of the red kite eggs had p ... | 2006 | 16213566 |
| conservation of the red kite milvus milvus (aves: accipitriformes) is not affected by the establishment of a broad hybrid zone with the black kite milvus migrans migrans in central europe. | among accipitriformes sensu stricto, only a few species have been reported to form hybrid zones; these include the red kite milvus milvus and black kite milvus migrans migrans. m. milvus is endemic to the western palearctic and has an estimated total population of 20-24,000 breeding pairs. the species was in decline until the 1970s due to persecution and has declined again since the 1990s due to ingestion of rodenticide-treated baits, illegal poisoning and changes in agricultural practices, part ... | 2016 | 27463515 |
| molecular characterization of haemosporidian parasites from kites of the genus milvus (aves: accipitridae). | despite the ecological significance and appeal of birds of prey, many aspects of their biology remain poorly known, including the diversity of parasites infecting them in the wild. we studied the diversity and prevalence of haemosporidian parasites infecting the two species of kites of the genus milvus, aiming to describe the phylogenetic relationships among them and with other haemosporidians, as well as their distribution in the two host species. black kites, milvus migrans, harboured a more d ... | 2013 | 23376529 |
| prioritizing species conservation: does the cape verde kite exist? | the cape verde kite (milvus milvus fasciicauda) is considered to be one of the rarest birds of prey in the world and at significant risk of extinction. for this reason there is great interest in both the taxonomic and the population status of this group. to help resolve its taxonomic status, we provide phylogenetic analyses based on three mitochondrial genes for a sampling of kites in the genus milvus, including a broad geographical sampling of black kites (milvus migrans), red kites (milvus mil ... | 2005 | 16006325 |
| cis-bromadiolone diastereoisomer is not involved in bromadiolone red kite (milvus milvus) poisoning. | anticoagulant rodenticides (ars) are widely used pesticides to control rodent populations. bromadiolone, a second generation anticoagulant rodenticide (sgars), is authorized in france to control the population of water voles (arvicola scherman). the persistence of sgars in rodents is responsible for secondary exposure or poisoning of predators and scavengers, and is of ecological concern for the conservation of endangered species. commercial formulations are a mixture of two diastereoisomers of ... | 2017 | 28605859 |
| supplementary feeding and endoparasites in threatened avian scavengers: coprologic evidence from red kites in their wintering stronghold. | many obligate and facultative avian scavengers are increasingly dependent on food provided in supplementary feeding stations (sfs), which are managed for the conservation of these species. deliberate feeding can influence disease-related host demography and population dynamics through physiological changes and density-dependent parasite acquisition and transmission, but information on this threat to avian scavengers is scarce. due to their effects on host aggregation and density, we hypothesised ... | 2017 | 28183038 |

| automated data analysis to rapidly derive and communicate ecological insights from satellite-tag data: a case study of reintroduced red kites. | analysis of satellite-telemetry data mostly occurs long after it has been collected, due to the time and effort needed to collate and interpret such material. delayed reporting reduces the usefulness of such data for nature conservation where timely information about animal movements is required. to counter this problem, we present a novel approach which combines automated analysis of satellite-telemetry data with rapid communication of insights derived from such data. a relatively simple algori ... | 2015 | 26508348 |
| age-dependent survival of island vs. mainland populations of two avian scavengers: delving into migration costs. | large terrestrial long-lived birds (including raptors) are typically sedentary on islands, even when they are migratory on the mainland. density-dependent variation in the age at first breeding has been described as responsible for the long-term persistence of long-lived bird populations on islands. however, sedentary island populations may also benefit from higher survival rates derived from the absence of migration costs, especially for young individuals. thus, sedentary island populations can ... | 2015 | 26013875 |
| widespread supplementary feeding in domestic gardens explains the return of reintroduced red kites milvus milvus to an urban area. | reintroductions are commonly used to mitigate biodiversity loss. one prominent example is that of the red kite milvus milvus, a charismatic raptor of conservation concern. this species has been reintroduced across the uk over the last 25 years following its near extinction after centuries of persecution. the species was not expected to recolonize urban areas; its historical association with human settlements is attributed to scavenging on human waste and refuse, a resource now greatly reduced on ... | 2015 | 25937644 |
| demographic consequences of poison-related mortality in a threatened bird of prey. | evidence for decline or threat of wild populations typically comes from multiple sources and methods that allow optimal integration of the available information, representing a major advance in planning management actions. we used integrated population modelling and perturbation analyses to assess the demographic consequences of the illegal use of poison for an insular population of red kites, milvus milvus. we first pooled into a single statistical framework the annual census of breeding pairs, ... | 2012 | 23155464 |
| monotonicity-constrained species distribution models. | flexible modeling frameworks for species distribution models based on generalized additive models that allow for smooth, nonlinear effects and interactions are of increasing importance in ecology. commonly, the flexibility of such smooth function estimates is controlled by means of penalized estimation procedures. however, the actual shape remains unspecified. in many applications, this is not desirable as researchers have a priori assumptions on the shape of the estimated effects, with monotoni ... | 2011 | 22073780 |
| bispectral index reveals death-feigning behavior in a red kite (milvus milvus). | red kites (milvus milvus) are birds of prey known to feign death in the presence of humans. an adult wild red kite was anesthetized with isoflurane for coelioscopy. during surgery, heart rate and respiratory rate ranged from 240 to 260 beats per minute and from 16 to 28 breaths rates per minute, respectively. pupil and corneal reflexes remained present, and body temperature was maintained at 40.4 degrees c (104.7 degrees f). suppression ratio was 0 during the anesthetic episode. the bispectral i ... | 2011 | 21877451 |
| long-term health effects of harness-mounted radio transmitters in red kites (milvus milvus) in england. | in 1989, the nature conservancy council and the royal society for the protection of birds commenced reintroduction of the red kite (milvus milvus) according to international union for conservation of nature criteria. following 22 years of intensive effort, the red kite reintroduction programme has been a success with an estimated 1000 pairs now breeding in england. post-release health surveillance is ongoing and has been achieved through radio-tracking, monitoring breeding at nest sites and path ... | 2011 | 21846683 |
| acute poisoning of red kites (milvus milvus) in france: data from the sagir network. | red kites (milvus milvus) are avian scavengers limited to europe, and they currently are listed as an endangered species worldwide. accidental poisoning is often listed as one of the threats to red kites throughout their range of distribution. the purpose of this article is to investigate the suspected poisoning cases reported to the french wildlife disease surveillance system. dead animals are submitted to a local veterinary laboratory for necropsy and when poisoning is suspected, samples are s ... | 2008 | 18436673 |
| unexpected high pcb and total ddt levels in the breeding population of red kite (milvus milvus) from doñana national park, south-western spain. | this study provides information on the current status of contamination by organochlorines (ddts, pcbs, pcdds and pcdfs) in the declining red kite (milvus milvus l.) population breeding in the doñana national park (dnp), south-western spain. analyses were performed in addled eggs collected between 1999 and 2001. dde concentrations ranged from 0.1 to 33.5 microg/g ww, representing more than 86% of the total ddts. of the samples studied, 50% showed dde levels above those associated with reproductiv ... | 2008 | 17727950 |
| territorial intrusions and copulation patterns in red kites, milvus milvus, in relation to breeding density. | two main paternity assurance strategies are generally found in birds: mate guarding and frequent copulations. the latter is expected particularly in species such as raptors that cannot guard their mates efficiently because of ecological constraints, such as frequent courtship feeding. i investigated the prelaying behaviour of red kites, in which the males courtship feed. i compared pair behaviour in situations of varying breeding density and simulated male territorial intrusions by presenting de ... | 2000 | 10715187 |
| urbanization and cattle density are determinants in the exposure to anticoagulant rodenticides of non-target wildlife. | the persistence and toxicity of second generation anticoagulant rodenticides (sgars) in animal tissues make these compounds dangerous by biomagnification in predatory species. here we studied the levels of sgars in non-target species of wildlife and the environmental factors that influence such exposure. liver samples of terrestrial vertebrates (n = 244) found dead between 2007 and 2016 in the region of aragón (ne spain) were analysed. the presence of sgars was statistically analysed with binary ... | 2019 | 30390453 |
| prevalence and genotyping of trichomonas infections in wild birds in central germany. | avian trichomonosis is a widespread disease in columbids and other birds, caused by ingestion of the unicellular flagellate trichomonas gallinae which proliferate primarily in the upper respiratory tracts. studies using genetic analyses have determined some highly pathogenic lineages in birds, but the prevalence and distribution of potentially pathogenic and non-pathogenic t. gallinae lineages in wild birds is still not well known. we examined 440 oral swab samples of 35 bird species collected b ... | 2018 | 30092001 |
| blood parasites in vectors reveal a united blackfly community in the upper canopy. | the behaviour of blood-sucking arthropods is a crucial determinant of blood protozoan distribution and hence of host-parasite coevolution, but it is very challenging to study in the wild. the molecular identification of parasite lineages in vectors can be a useful key to understand the behaviour and transmission patterns realised by these vectors. | 2020 | 32539849 |
| acute and chronic lead exposure in four avian scavenger species in switzerland. | despite irrefutable evidence of its negative impact on animal behaviour and physiology, lethal and sublethal lead poisoning of wildlife is still persistent and widespread. for scavenging birds, ingestion of ammunition, or fragments thereof, is the major exposure route. in this study, we examined the occurrence of lead in four avian scavengers of switzerland and how it differs between species, regions, and age of the bird. we measured lead concentration in liver and bone of the two main alpine av ... | 2018 | 30238146 |
| predicting strike susceptibility and collision patterns of the common buzzard at wind turbine structures in the federal state of brandenburg, germany. | with the increase in wind turbines, bird collisions have developed as a potential hazard. in the federal state of brandenburg, germany, despite the on-going mitigation efforts of increasing the distances of wind turbines from the breeding areas of the more severely affected populations of red kites (milvus milvus), the additional detrimental influences on the buzzard populations (buteo buteo) have added to the challenges for wind power expansion. using data on the regional distribution of the bu ... | 2020 | 31978066 |
| culture- and molecular-based detection of swine-adapted salmonella shed by avian scavengers. | salmonella can play an important role as a disease agent in wildlife, which can then act as carriers and reservoirs of sanitary importance at the livestock-human interface. transmission from livestock to avian scavengers can occur when these species consume contaminated carcasses and meat remains in supplementary feeding stations and rubbish dumps. we compared the performance of pcr-based detection with conventional culture-based methods to detect salmonella in the faeces of red kites (milvus mi ... | 2018 | 29710649 |
| direct evidence of poison-driven widespread population decline in a wild vertebrate. | toxicants such as organochlorine insecticides, lead ammunition, and veterinary drugs have caused severe wildlife poisoning, pushing the populations of several apex species to the edge of extinction. these prime cases epitomize the serious threat that wildlife poisoning poses to biodiversity. much of the evidence on population effects of wildlife poisoning rests on assessments conducted at an individual level, from which population-level effects are inferred. contrastingly, we demonstrate a strai ... | 2020 | 32601195 |
| avian scavengers as bioindicators of antibiotic resistance due to livestock farming intensification. | industrial food animal production uses huge amounts of antibiotics worldwide. livestock, their excreta used for manure and meat subproducts not intended for human consumption can all play important roles in the transmission of bacterial resistance to wildlife. vultures and other scavengers can be directly exposed to active antibiotics ingested while feeding on livestock carcasses. this study evaluates whether bacterial resistance in the red kite (milvus milvus) differs between two wintering area ... | 2020 | 32455739 |
| corticosterone mediates telomere length in raptor chicks exposed to chemical mixture. | stressors experience early in life by animals may have carry over impacts on life-traits over the life cycle. accelerated telomere attrition induced by stress during development and growth could play a role in such delayed effects. among stressors, exposure to chemicals may modify telomere dynamic but, to date, the trends evidenced between exposure and telomere shortening remains inconsistent. moreover, the role of corticosterone as a possible mediator of chemical impact on telomere is not yet c ... | 2020 | 31841853 |
