gastrointestinal parasites in captive and free-ranging birds and potential cross-transmission in a zoo environment.gastrointestinal parasites are commonly reported in wild birds, but transmission amongst avifauna in zoological settings, and between these captive birds and wild birds in surrounding areas, remains poorly understood. a survey was undertaken to investigate the occurrence of gastrointestinal parasites in captive and free-ranging birds at bristol zoo gardens between may and july 2016. a total of 348 fecal samples from 32 avian species were examined using the mini-flotac flotation method. parasites ...201829517437
the decline of the turtle dove: dietary associations with body condition and competition with other columbids analysed using high-throughput sequencing.dietary changes linked to the availability of anthropogenic food resources can have complex implications for species and ecosystems, especially when species are in decline. here, we use recently developed primers targeting the its2 region of plants to characterize diet from faecal samples of four uk columbids, with particular focus on the european turtle dove (streptopelia turtur), a rapidly declining obligate granivore. we examine dietary overlap between species (potential competition), associa ...201829927007
any despot at my table? competition among native and introduced bird species at garden birdfeeders in bird feeding constitutes a massive provision of food that can support bird communities, but there is a growing concern it might favour the establishment of exotic species that could be detrimental to others. how bird species compete with novel species for this anthropogenic food resources needs to be assessed. here, we investigated competition in wintering bird communities at garden birdfeeders. we evaluated whether - and how much - bird access to resources is hampered by the presence of ...202032475721
evidence of cryptic species in the genus tinaminyssus (acari: rhinonyssidae) based on morphometrical and molecular data.the study of cryptic species allows to describe and to understand biodiversity, and the evolutionary processes shaping it. mites of the family rhinonyssidae are permanent parasites of the nasal cavities of birds, currently including about 500 described species and 12 genera. here, we tested the hypothesis that mites from five populations of the genus tinaminyssus-three isolated from european turtle doves (streptopelia turtur), and two from eurasian collared doves (streptopelia decaocto; aves: co ...201829876760
mtdna genetic diversity and structure of eurasian collared dove (streptopelia decaocto).the eurasian collared dove (streptopelia decaocto) is one of the most successful biological invaders among terrestrial vertebrates. however, little information is available on the genetic diversity of the species. a total of 134 eurasian collared doves from europe, asia and the caribbean (n = 20) were studied by sequencing a 658-bp length of mitochondrial dna (mtdna) cytochrome oxidase i (coi). fifty-two different haplotypes and relatively high haplotype and nucleotide diversities (hd±sd = 0.843 ...201829518164
high prevalence of trichomonas gallinae in wild columbids across western and southern europe.avian trichomonosis is known as a widespread disease in columbids and passerines, and recent findings have highlighted the pathogenic character of some lineages found in wild birds. trichomonosis can affect wild bird populations including endangered species, as has been shown for mauritian pink pigeons nesoenas mayeri in mauritius and suggested for european turtle doves streptopelia turtur in the uk. however, the disease trichomonosis is caused only by pathogenic lineages of the parasite trichom ...201728521843
first detection of arcobacter sp. in eurasian collared doves (streptopelia decaocto).data about the presence of arcobacter in wild birds are currently lacking. in this study cloacal swabs from 95 collared doves (streptopelia decaocto), submitted to the department of veterinary medical sciences (bologna, italy) between 2011 and 2013 from various urban and suburban areas of the emilia-romagna region (northern italy), were tested for the presence of arcobacter sp. by a rrna 23s nested polymerase chain reaction (pcr). eighteen out of 95 (19%) samples showed the expected pcr product. ...201425546070
aldrin poisoning of sarus cranes (grus antigone) and a few granivorous birds in keoladeo national park, bharatpur, india.: between 1987-88 and 1989-90, 18 sarus cranes (grus antigone), more than 50 collared doves (streptopelia decaocto) and a few blue rock pigeons (columba livia) were found dead during winter in keoladeo national park, bharatpur, which coincided with the application of aldrin in the crop fields around the park. brain tissue of sarus cranes, collared doves and blue rock pigeons contained an average of 19.33 (3.56-43.46), 15.19 (7.40-20.70), and 20.42 (14.61-26.23) ppm, wet weight, of dieldrin, resp ...199324201581
natural infections with pigeon paramyxovirus serotype 1: pathologic changes in eurasian collared-doves ( streptopelia decaocto) and rock pigeons ( columba livia) in the united states.pigeon paramyxovirus serotype 1 (ppmv-1) is a globally distributed, virulent member of the avian paramyxovirus serotype 1 serogroup that causes mortality in columbiformes and poultry. following introduction into the united states in the mid-1980s, ppmv-1 rapidly spread causing numerous mortality events in eurasian collared-doves ( streptopelia decaocto) (ecdos) and rock pigeons ( columba livia) (ropis). the investigators reviewed pathological findings of 70 naturally infected, free-ranging colum ...201728382855
