| organochlorines and trace elements in upland game birds harvested in canada. | american woodcock, common snipe, two species of ptarmigan (willow and rock), and three species of grouse (ruffed, spruce, and sharp-tailed) were collected from 21 locations between 1991 and 1994 as part of a nationwide survey of contaminants in game birds harvested in canada. breast muscle was analysed for organochlorines (chlorobenzenes, hexachlorocyclohexanes, chlordane-related compounds, ddt metabolites, mirex, dieldrin, and pcbs) and trace elements (hg, cd, se, and as). the concentrations of ... | 2006 | 16055172 |
| toxoplasma gondii in waterfowl: the first detection of this parasite in anas crecca and anas clypeata from italy. | understanding the spread of toxoplasma gondii in waterfowl is of interest for elucidating the potential involvement of these birds in maintaining the parasitic life cycle because birds are exposed to these parasites. sera from 103 adult, free-range game birds, representing 13 different species living in the italian wetlands, were examined using modified agglutination tests for antibodies specific to t. gondii . in seropositive birds, the brain and heart were homogenized and dna was extracted to ... | 2013 | 23145510 |
| embryonic brain growth in two shorebirds: charadrius vociferus and gallinago gallinago. | the sizes of six brain regions and of the whole brain were measured for a series of embryonic killdeer, charadrius vociferus, and common snipe, gallinago gallinago, to examine (1) the allometric relationship between whole brain and body mass through ontogeny, (2) whether the longer incubation period of the killdeer corresponds to a larger brain at hatch, (3) whether different brain regions grow independently in size through ontogeny, and (4) whether relative size of particular brain regions rela ... | 1996 | 8828861 |
| [trichocephaloidis beauporti n. sp., new cestode of charadriiformes and some passeriformes in guadelupa (author's transl)]. | description of a new species of dilepididae, trichocephaloidis beauporti n. sp., parasite of charadriiform birds (tringa flaviceps; micropalama himantopus; gallinago gallinago delicata; squatarola squatarola) of guadelupa and also of a passeriforme, quiscalus lugubris. this species can easily be separated from other trichocephaloidis by the structure of bifid rostellum and the length of hooks (70-77 mu). trichocephaloidis charadrii is synonym of trichocephaloidis megalocephala. | 2006 | 970865 |

| when moult overlaps migration: moult-related changes in plasma biochemistry of migrating common snipe. | moult of feathers entails considerable physiological and energetic costs to an avian organism. even under favourable feeding conditions, endogenous body stores and energy reserves of moulting birds are usually severely depleted. thus, most species of birds separate moult from other energy-demanding activities, such as migration or reproduction. common snipe gallinago gallinago is an exception, as during the first autumn migration many young snipe initiate the post-juvenile moult, which includes ... | 2017 | 28286713 |
| plumage quality mediates a life-history trade-off in a migratory bird. | moult is one of the most costly activities in the annual cycle of birds and most avian species separate moult from other energy-demanding activities, such as migration. to this end, young birds tend to undergo the first post-juvenile moult before the onset of migration, but in some species the time window for the pre-migratory feather replacement is too narrow. we hypothesized that in such species an increased investment in the structural quality of juvenile feathers may allow to retain juvenile ... | 2016 | 27766111 |
| ecological, physiological, and morphological correlates of blood hemoglobin concentration in a migratory shorebird. | the information on the phenotypic and ecological factors that influence hemoglobin concentration in free-living birds is scarce. in order to recognize sources of variation in hemoglobin levels of migratory shorebirds, we measured whole-blood hemoglobin concentration in 553 juvenile and 166 adult common snipe gallinago gallinago during autumn migration through central poland. among the intrinsic determinants of hemoglobin concentration in common snipe, we identified traits such as age, wing morph ... | 2015 | 25461642 |
| morpho-functional characteristics of the scolex of wardium chaunense (cestoda: aploparaksidae) penetrated into host intestine. | the scoleces of wardium chaunense penetrated into the intestinal wall of a snipe (gallinago gallinago) were examined by light and transmission electron microscopy for the first time. naturally, the scolex is characterised by a shorter length in comparison with when it is removed from the host. ultrastructural characteristics of the main parts of the scolex, such as suckers, rostellum and rostellar sac are reported. partial degradation of the radial muscles of the suckers is clearly recognised; t ... | 2014 | 24178746 |
| sonation in the male common snipe (capella gallinago gallinago l.) is achieved by a flag-like fluttering of their tail feathers and consequent vortex shedding. | male common snipe (capella gallinago gallinago) produce a 'drumming' sound with their outer tail feathers during their mating dives, but little is known about how this is achieved. we investigated the movements and sound producing capabilities of the outer tail feathers. using a wind tunnel, we compared observations of the frequencies of sound produced with the predictions from aerodynamic theory. the feathers were also filmed in an air-flow with a high speed video camera, and subjected to morph ... | 2010 | 20400646 |

| louse flies of charadrii and scolopaci shorebirds migrating through central europe. | louse flies are blood-sucking ectoparasites of birds and mammals of veterinary and medical importance. these flies damage host skin and serve as vectors for blood-associated pathogens. little is known about their phenology, host selection, and prevalence in wild birds. our study provided a broad-scale assessment of louse flies parasitizing charadrii and scolopaci shorebirds during their migration through central europe. we collected louse flies from 3,129 specimens in 22 species of shorebirds at ... | 2020 | 31596675 |
| the influence of different aspects of grouse moorland management on nontarget bird assemblages. | conflict between stakeholders with opposing interests can hamper biodiversity conservation. when conflicts become entrenched, evidence from applied ecology can reveal new ways forward for their management. in particular, where disagreement exists over the efficacy or ethics of management actions, research clarifying the uncertain impacts of management on wildlife can move debates forwards to conciliation.here, we explore a case-study of entrenched conflict where uncertainty exists over the impac ... | 2019 | 31641457 |
| integrating intraseasonal grassland dynamics in cross-scale distribution modeling to support waterbird recovery plans. | despite much discussion about the utility of remote sensing for effective conservation, the inclusion of these technologies in species recovery plans remains largely anecdotal. we developed a modeling approach for the integration of local, spatially measured ecosystem functional dynamics into a species distribution modeling (sdm) framework in which other ecologically relevant factors are modeled separately at broad scales. to illustrate the approach, we incorporated intraseasonal water-vegetatio ... | 2020 | 31461173 |
