| use of recombinant vaccinia-rabies glycoprotein virus for oral vaccination of wildlife against rabies: innocuity to several non-target bait consuming species. | the pathogenicity of a vaccinia recombinant virus expressing the rabies glycoprotein (vvtggrab) was tested in several wild animal species which could compete with the natural rabies host, the red fox (vulpes vulpes) in consuming vaccine baits in europe. the following species were included in this study: wild boar (sus scrofa), eurasian badger (meles meles), wood mouse (apodemus sylvaticus), yellow-necked mouse (apodemus flavicollis), bank vole (clethrionomys glareolus), common vole (microtus arv ... | 1989 | 2681844 |
| [the physiologic electroretinogram of the raptor bird--clinical and theoretical aspects]. | a method of electroretinography applicable to birds is described in this paper by the example of common buzzard (buteo buteo l.). electroretinograms (erg) under dark and bright adaptation as well as flicker ergs were recorded from 15 common buzzards, and normograms were established. methodological reliability was verified by a tenfold test on one animal. the results are compared with erg findings from dog and are discussed with reference to behaviour physiology and clinical diagnosis. | 1989 | 2774815 |
| isolation of a mycoplasma sp. from three buzzards (buteo spp.). | mycoplasma spp. were isolated from the respiratory tissues of three buzzards. bird i, a rough-legged buzzard (buteo lagopus), showed airsacculitis, catarrhal-fibrinous pneumonia, and catarrhal tracheitis. bird ii, a common buzzard (buteo buteo), revealed mycotic airsacculitis, bronchitis and pneumonia. bird iii was a healthy rough-legged buzzard. all isolates metabolized glucose but not arginine and were serologically identical by immunofluorescence and growth-inhibition tests. no serological cr ... | 1982 | 7049150 |
| [treatment of a mandibular fracture in a common buzzard (buteo buteo l., 1758)]. | a common buzzard with an old dislocated unilateral mandibular fracture causing apathy, inappetence and reduction of body weight was presented for surgical treatment (reduction of fracture, intramedullary pinning with a kirschner wire). postoperatively the wild bird recovered rapidly and could eat without assistance after four days. evaluation of the raptor six weeks p.op. revealed normal occlusion and fracture healing. therefore, it was decided to release the bird into wildlife. | 1996 | 8767186 |
| seroepizootiology of selected infectious disease agents in free-living birds of prey in germany. | four hundred forty-eight blood plasma samples from free-living birds of prey from berlin and the brandenburg area in eastern germany were tested for antibodies against newcastle disease virus (ndv), falcon herpesvirus (fhv), owl herpesvirus (ohv), and chlamydia psittaci. antibodies to ndv were detected in 6 (2%) of 346 tested diurnal birds of prey, whereas none of the owls (n = 55) was positive. the positive samples originated from two common buzzards (buteo buteo), three ospreys (pandion haliac ... | 2001 | 11272489 |

| competitive interactions among raptors in boreal forests. | we examined inter-specific interactions among goshawks ( accipiter gentilis), common buzzards (buteo buteo) and honey buzzards (pernis apivorus) in western finland in 1983-1996. because goshawks are among the largest birds of prey species in boreal forests they may take over the nest of smaller and less-competitive forest-dwelling raptors when searching for suitable places for breeding. accordingly, more than half of newly established goshawk territories were found on the territories previously ... | 2004 | 15375689 |
| evidence for cryptic speciation of leucocytozoon spp. (haemosporida, leucocytozoidae) in diurnal raptors. | species of leucocytozoon (haemosporida, leucocytozoidae) traditionally have been described based on morphological characters of their blood stages and host cells, with limited information on their avian host specificity. based on the current taxonomy, leucocytozoon toddi is the sole valid species of leucocytozoids parasitizing falconiform birds. using a nested polymerase chain reaction protocol, we determined the prevalence of leucocytozoon infection in 5 species of diurnal raptors from californ ... | 2006 | 16729697 |

| mesopredator release by an emergent superpredator: a natural experiment of predation in a three level guild. | intraguild predation (igp) is widespread but it is often neglected that guilds commonly include many layers of dominance within. this could obscure the effects of igp making unclear whether the intermediate or the bottom mesopredator will bear higher costs from the emergence of a new top predator. | 2010 | 21151912 |
| presence of toxoplasma gondii and neospora caninum dna in the brain of wild birds. | toxoplasma gondii infections are prevalent in many avian species and can cause mortality in some bird hosts. although t. gondii has been isolated from various species of birds, the role of many different species of wild birds in the epidemiology of t. gondii remains unknown. neospora caninum, a closely related parasite to t. gondii, has been recently confirmed to infect domestic chickens and wild birds such as house sparrows (passer domesticus). the present study reports the presence of t. gondi ... | 2011 | 21831525 |

| holding power of three different pin designs in the femur and ulna of the common buzzard (buteo buteo). | external skeletal fixation is generally considered the best stabilization technique for immobilizing avian long bone fractures, but one of its major complications is the failure of bone-fixation pin interface or the loss of holding power. consequently, this study is aimed at elucidating which pin design offers more pull-out strength in certain bones of the common buzzard (buteo buteo). to achieve this objective, three pin designs (a smooth design and two negative profile threaded designs, with d ... | 2011 | 22204047 |

| predatory bird species show different patterns of hydroxylated polychlorinated biphenyls (ho-pcbs) and polychlorinated biphenyls (pcbs). | hydroxylated metabolites of polychlorinated biphenyls (ho-pcbs) have previously been associated with endocrine disrupting effects. since metabolic capacity may differ among species, we investigated the levels and profiles of ho-pcbs and pcbs in livers of four predatory bird species from belgium. maximum concentrations for sum ho-pcbs were found in the common buzzard (buteo buteo) up to 13 700 pg/g wet weight (ww). the most prominent ho-pcb congener in all bird species was 4-ho-cb 187 (up to 6420 ... | 2008 | 18522135 |
| species-specific polymerase chain reactions for the detection of mycoplasma buteonis, mycoplasma falconis, mycoplasma gypis, and mycoplasma corogypsi in captive birds of prey. | mycoplasmas are pathogens of different avian species, but the role of mycoplasma in raptors is not yet completely determined. as mycoplasma isolation and identification present several difficulties, species-specific polymerase chain reactions (pcrs) for the detection of mycoplasmas found in birds of prey (mycoplasma buteonis, mycoplasma corogypsi, mycoplasma falconis, and mycoplasma gypis) were established. the specificity of the pcr methods were investigated using known avian mycoplasma referen ... | 2008 | 18459303 |
| heavy metal (cd, pb, zn) and metalloid (as) content in raptor species from galicia (nw spain). | as top consumers in food chains, birds of prey forage over large geographical areas and so might be expected to accumulate environmental contaminants which are distributed in the environment. these wild animals can offer opportunities to detect and assess the toxicological effects of different inorganic elements on terrestrial ecosystems. in this study, different raptor species, both diurnal and nocturnal, were investigated for heavy metal (pb, cd and zn) and as concentrations in liver samples, ... | 2008 | 17617459 |
| plasma phenylacetate and 1-naphthyl acetate hydrolyzing activities of wild birds as possible non-invasive biomarkers of exposure to organophosphorus and carbamate insecticides. | organophosphorus and carbamate insecticides inhibit the carboxylesterases found in plasma. therefore, these carboxylesterases might be used as biomarkers of exposure to these insecticides. this work initiates the characterization of the phenylacetate (pa) and 1-nafthylacetate (na) hydrolyzing activities (paase and naase) in the plasma of 11 different wild bird species and aims to determine their suitability as biomarkers of exposure. paase activity values, expressed as mumol product/30min/ml pla ... | 2007 | 17174487 |
