| first report of thelazia sp. from a captive oriental white stork (ciconia boyciana) in japan. | nematodes of the genus thelazia were recovered from the cornea and inferior conjunctival sac of an immature oriental white stork (ciconia boyciana). the bird hatched and reared at the toyooka oriental white stork breeding center, hyogo prefecture, japan, but died of chlamydiosis. there were neither gross nor histopathologic ophthalmic lesions. the eye worm from a bird is believed to be first reported in japan. as regarding reintroduction plan for the oriental white stork, control measures for pr ... | 1999 | 10027175 |
| determination of the complete nucleotide sequence and haplotypes in the d-loop region of the mitochondrial genome in the oriental white stork, ciconia boyciana. | the complete nucleotide sequence of the mitochondrial genome of the oriental white stork, ciconia boyciana, has been determined from captive storks by a novel method incorporating long pcr and shotgun sequencing. 13 protein-coding genes, two ribosomal rna genes and 22 transfer rna genes were identified as in other vertebrate mitochondrial genomes. the position and direction of the nadh6 and trna-glu genes were the same as previously reported for avian mitochondrial genomes. a 71 bp direct repeat ... | 2000 | 10846618 |
| giardiasis in a white stork in the netherlands. | giardia sp. was found in the white stork (ciconia ciconia) in the netherlands for the first time. the giardia sp. trophozoites that were found in the feces of a 6-wk-old white stork, were examined by light microscopy. the parasites closely resembled giardia ardeae that had been isolated by others from several species of wading birds belonging to the order ciconiiformes, sharing a deeply notched adhesive disk, a single caudal flagellum, and a single round median body. serologically, the parasites ... | 2000 | 11085441 |
| assessment of genotoxic damage by the comet assay in white storks (ciconia ciconia) after the doñana ecological disaster. | single cell gel electrophoresis, the so-called "comet" assay, was performed as a genotoxicity test in white storks sampled in an area heavily contaminated after the ecological disaster in south western spain. this disaster occurred as a consequence of a massive toxic spillage of acid waste rich in heavy metals that impacted on the doñana national park. the importance of this protected area as a breeding and wintering site for many endangered bird species makes this analysis of dna damage of spec ... | 2001 | 11320147 |

| identification and analysis of a new hepadnavirus in white storks. | we identified, cloned, and functionally characterized a new avian hepadnavirus infecting storks (sthbv). sthbv has the largest dna genome of all avian hepadnaviruses and, based on sequence and phylogenetic analysis, is most closely related to, but distinct from, heron hepatitis b virus (hhbv). unique for sthbv among the other avian hepadnaviruses is a potential hnf1 binding site in the pres promoter. in common only with hhbv, sthbv has a myristylation signal on the s and not the pres protein, tw ... | 2001 | 11601923 |
| dna damage in birds after the mining waste spill in southwestern spain: a comet assay evaluation. | in april 1998, an ecological disaster resulting from a massive toxic spill of mining acid waste rich in heavy metals posed a serious threat to the doñana national park in southwestern spain. this especially important protected area is the nesting and breeding site for many endangered bird species; white storks (ciconia ciconia) and black kites (milvus migrans) are considered the more representative. the suitability of the comet assay as a biomarker for genotoxic analysis in environmental biomoni ... | 2001 | 11797841 |

| adaptive allocation of stress-induced deformities on bird feathers. | physiological stress during ontogeny is known to cause abnormalities in keratin structures of vertebrates, but little is known about if and how organisms have evolved mechanisms to reduce the negative effects of these abnormalities. stress experienced during avian feather growth is known to lead to the formation of fault bars, and thereby to the weakening of feathers because of shortage and slimming of barbules. here we propose and test a new hypothesis (the 'fault bar allocation hypothesis') ac ... | 2004 | 15009263 |
| toxoplasma gondii antibodies in the white stork ciconia ciconia. | the prevalence of toxoplasma gondii in chicks of wild birds and captive individuals was studied in the poznań environs and in the poznań zoological garden in the years 2002-2003. bird blood was tested for t. gondii antibodies by an indirect fluorescent antibody test. t. gondii antibodies were detected from 5.8% of 205 analysed white stork chicks and 13.6% of 44 analysed adult storks in the zoo. because toxoplasmosis is one of the more common parasitic zoonoses worldwide, we briefly discuss the p ... | 2004 | 15298054 |

| 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 |
| house sparrows benefit from the conservation of white storks. | as with many farmland bird species, the house sparrow passer domesticus is declining in europe, mainly due to intensification of agriculture reducing nest sites and food supplies. during 2002-2005, we studied the population size and nest site characteristics of house sparrows breeding within white stork ciconia ciconia nests in a large area of agricultural landscape within western poland. to explain sparrow density within stork nests, we examined characteristics of white stork nests (position, a ... | 2007 | 17216183 |

| sexual dimorphism of acoustic signals in the oriental white stork: non-invasive identification of sex in birds. | identification of the sex of birds is important for captive breeding of endangered species. in the oriental white stork (ciconia boyciana), an endangered species, both sexes produce an acoustic signal called "clatter" by rattling their mandibles together to generate sounds. we examined the structure of male and female clatter to determine whether clatter is sexually dimorphic. the acoustic structure of the clatter of the two sexes proved to be dimorphic with respect to the fundamental frequency; ... | 2004 | 15333993 |
| sexual differences in food preferences in the white stork: an experimental study. | sex differences in the foraging ecology of monomorphic species are poorly understood, due to problems with gender identification in field studies. in the current study, we used experimental conditions to investigate the food preferences of the white stork ciconia ciconia, an opportunistic species in terms of food, but characterised by a low level of sexual dimorphism. during a 10-day experiment, 29 individuals (20 females and 9 males) were studied by means of a 'cafeteria test' in which the stor ... | 2017 | 28389678 |
