| long-term trends in first arrival and first egg laying dates of some migrant and resident bird species in northern italy. | climate change is affecting the phenology of seasonal events in europe and the northern hemisphere, as shown by several studies of birds' timing of migration and reproduction. here, we analyse the long-term (1982-2006) trends of first arrival dates of four long-distance migratory birds [swift (apus apus), nightingale (luscinia megarhynchos), barn swallow (hirundo rustica), and house martin (delichon urbicum)] and first egg laying dates of two migrant (swift, barn swallow) and two resident specie ... | 2007 | 17375338 |
| results of arbovirological examination of birds of the family hirundinidae in czechoslovakia. | migratory birds (swallow, hirundo rustica; sand martin, riparia riparia; house martin, delichon urbica) caught in southern moravia (czechoslovakia) in 1984-87 were examined for arbovirus infections. isolation experiments were carried out using blood samples of 183 birds (52 swallows, 107 sand martins, and 24 house martins). the results were negative. serological examinations of 136 birds (36 swallows, 86 sand martins, and 14 house martins) were made by haemagglutination-inhibition test (hit) usi ... | 1989 | 2562171 |
| plasmodium delichoni n. sp.: description, molecular characterisation and remarks on the exoerythrocytic merogony, persistence, vectors and transmission. | malaria parasite plasmodium (novyella) delichoni n. sp. (haemosporida, plasmodiidae) was found in a widespread eurasian songbird, the common house martin delichon urbicum (hirundinidae). it is described based on the morphology of its blood stages and segments of the mitochondrial cytochrome b and apicoplast genes, which can be used for molecular identification of this species. erythrocytic meronts and gametocytes are strictly nucleophilic, and mature gametocytes possess pigment granules of marke ... | 2016 | 27000087 |

| detecting transmission areas of malaria parasites in a migratory bird species. | the identification of the regions where vector-borne diseases are transmitted is essential to study transmission patterns and to recognize future changes in environmental conditions that may potentially influence the transmission areas. sgs1, one of the lineages of plasmodium relictum, is known to have active transmission in tropical africa and temperate regions of europe. nuclear sequence data from isolates infected with sgs1 (based on merozoite surface protein 1 (msp1) allelic diversity) have ... | 2015 | 25968571 |
| yeasts vectored by migratory birds collected in the mediterranean island of ustica and description of phaffomyces usticensis f.a. sp. nov., a new species related to the cactus ecoclade. | nine yeast species belonging to genera candida, cryptococcus, phaffomyces, rhodotorula and wickerhamomyces, and one species of aureobasidium genus were isolated from the cloaca of migratory birds. candida glabrata and c. inconspicua were the species most frequently isolated and wickerhamomyces sylviae, which has recently been described as a new species isolated from bird cloaca, was again found. the majority of isolates showed the ability to grow up to 40 °c and/or at ph 3.0, two environmental c ... | 2014 | 24981278 |
| impact of routine bacillus thuringiensis israelensis (bti) treatment on the availability of flying insects as prey for aerial feeding predators. | since 1980, mosquito breeding habitats in the upper rhine valley were routinely treated with bacillus thuringiensis var. israelensis (bti). bti is considered to significantly reduce the number of mosquitoes, and - especially when used in higher dosages - to be toxic to other nematocera species, e.g. chironomidae, which could be food sources for aerial feeding predators. to investigate direct and indirect effects of routine bti treatment on food sources for aerial feeding predators, the availabil ... | 2017 | 28202094 |
| phenotypic and genotypic characteristics of antimicrobial resistant escherichia coli isolated from symbovine flies, cattle and sympatric insectivorous house martins from a farm in the czech republic (2006-2007). | the prevalence of antimicrobial resistant escherichia coli was tested in symbovine flies and sympatric house martins (delichon urbica) at a dairy farm. antimicrobial resistant e. coli was detected in 89% (n=147) of isolates from flies within a calf barn. isolates with the same antimicrobial resistance phenotypes, genes, and pulsotypes were found between both fly and calf e. coli isolates, suggesting that the calves were the initial source of the antimicrobial resistant strains in fly isolates. s ... | 2010 | 20350731 |
| [ectoparasites from nests of swallows delichon urbica and hirundo rustica collected in autumn]. | in the years 1989-1990 53 nests of d. urbica and 47 nests of h. rustica were collected from resko (province szczecin). in 95 nests 2483 ectoparasites representing 3 species: c. hirundinis (73.1%), oe. hirundinis (26.5%) and c. gallinae (0.4%) were found. the highest mean number of specimens per nest was observed in the nest of d. urbica (29.5) and the lowest in nest of h. rustica (19.5). the highest (57) of nests was inhabited by 2 parasites species, 35 nests--by 1 and 3 nests--by 3 species. the ... | 1993 | 8128730 |
| increased detrimental effects of ectoparasites on their bird hosts during adverse environmental conditions. | parasites are usually assumed to negatively affect fitness components of their hosts, particularly during adverse environmental conditions. we experimentally tested whether the ectoparasitic house martin bug (oeciacus hirundinis) had larger negative effects on its house martin (delichon urbica) host during second clutches. conditions for reproduction decreased during the season, being less favourable for the second clutch than the first clutch. this was demonstrated by smaller clutch sizes, lowe ... | 1993 | 28312947 |
| ectoparasites and host energetics: house martin bugs and house martin nestlings. | we measured the energy cost of ectoparasitism in an experimental study of the house martin bug oeciacus hirundinis and its main host, nestlings of the house martin delichon urbica. nests were randomly assigned to inoculation with 0 (control) 10, or 100 bugs during egg laying, and this resulted in statistically significant differences in parasite loads following fledging of nestlings. parasite loads negatively affected house martin nestlings as estimated from their body mass at age 16 days and fr ... | 1994 | 28313901 |
| increase in a heat-shock protein from blood cells in response of nestling house martins (delichon urbica) to parasitism: an experimental approach. | heat-shock proteins (hsps) are synthesized by animals and plants in response to various stressors. the level of the hsp60 stress protein was measured from the cell fraction of peripheral blood obtained from nestling house martins (delichon urbica) to test whether ectoparasitism increased the concentration of stress protein. we assessed hsp from nestlings raised in nests previously treated with an insecticide or infested with 50 martin bugs (oeciacus hirundinis). in addition, haematozoa infection ... | 1998 | 28308065 |
| genetic and environmental components of phenotypic variation in immune response and body size of a colonial bird, delichon urbica (the house martin). | directional selection for parasite resistance is often intense in highly social host species. using a partial cross-fostering experiment we studied environmental and genetic variation in immune response and morphology in a highly colonial bird species, the house martin (delichon urbica). we manipulated intensity of infestation of house martin nests by the haematophagous parasitic house martin bug oeciacus hirundinis either by spraying nests with a weak pesticide or by inoculating them with 50 bu ... | 2000 | 10971693 |
| the influence of environmental conditions on immune responses, morphology and recapture probability of nestling house martins (delichon urbica). | nestling birds produced later in the season are hypothesized to be of poor quality with a low probability of survival and recruitment. in a spanish population of house martins (delichon urbica), we first compared reproductive success, immune responses and morphological traits between the first and the second broods. second, we investigated the effects of an ectoparasite treatment and breeding date on the recapture rate the following year. due probably to a reverse situation in weather conditions ... | 2001 | 28547445 |
| flexibility in flight behaviour of barn swallows (hirundo rustica) and house martins (delichon urbica) tested in a wind tunnel. | the flight behaviour of barn swallows (hirundo rustica) and house martins (delichon urbica) was tested in a wind tunnel at 15 combinations of flight angles and speeds. in contrast to that of most other small passerines, the intermittent flight of hirundines rarely consists of regular patterns of flapping and rest phases. to vary mechanical power output, both species used intermittent flight, controlling the number of single, pulse-like wingbeats per unit time. house martins in descent tended to ... | 2001 | 11273808 |
| wingbeat frequency of barn swallows and house martins: a comparison between free flight and wind tunnel experiments. | the flight paths and wingbeat patterns of 39 barn swallows (hirundo rustica) and 26 house martins (delichon urbica) were recorded by tracking radar during the spring migration. depending mostly on flight angle, hirundines performed anything from continuous flapping flight during climbing to single pulse-like wing beats during descent. unlike most other passerines, hirundines rarely showed regular flapping and rest phases, allowing them to be distinguished from other bird migrants by radar echo s ... | 2002 | 12124369 |
| vane emargination of outer tail feathers improves flight manoeuvrability in streamerless hirundines, hirundinidae. | recent studies have suggested that the proximal part of the swallow (hirundo rustica) tail streamer appears to aid turning flight, as expected if streamers evolved initially purely through natural selection for enhanced manoeuvrability. however, the evolution of slender aerodynamically advantageous streamers is also predicted by an alternative hypothesis, which suggests that such a trait could develop primarily to ameliorate the aerodynamic cost of a long size-dimorphic tail. to distinguish betw ... | 2004 | 15315899 |
| malarial parasites decrease reproductive success: an experimental study in a passerine bird. | malarial parasites are supposed to have strong negative fitness consequences for their hosts, but relatively little evidence supports this claim due to the difficulty of experimentally testing this. we experimentally reduced levels of infection with the blood parasite haemoproteus prognei in its host the house martin delichon urbica, by randomly treating adults with primaquine or a control treatment. treated birds had significantly fewer parasites than controls. the primaquine treatment increase ... | 2005 | 15688214 |
| [seasonal dynamics of ceratophyllus hirundinis (curtis, 1826) (siphonaptera, insecta) in the nests of delichon urbica (l.)]. | the annual cycle of c. hirundinis was studied in 61 nests of delichon urbica. fleas were found in the 45 nests. in the number of adults two peaks were observed, the lower in march and the higher in october. females outnumbered males throughout the year. | 2004 | 16892602 |
| wake structure and wingbeat kinematics of a house-martin delichon urbica. | the wingbeat kinematics and wake structure of a trained house martin in free, steady flight in a wind tunnel have been studied over a range of flight speeds, and compared and contrasted with similar measurements for a thrush nightingale and a pair of robins. the house martin has a higher aspect ratio (more slender) wing, and is a more obviously agile and aerobatic flyer, catching insects on the wing. the wingbeat is notable for the presence at higher flight speeds of a characteristic pause in th ... | 2007 | 17264054 |
| malaria infection and feather growth rate predict reproductive success in house martins. | carry-over effects take place when events occurring in one season influence individual performance in a subsequent season. blood parasites (e.g. plasmodium and haemoproteus) have strong negative effects on the body condition of their hosts and could slow the rate of feather growth on the wintering grounds. in turn, these winter moult costs could reduce reproductive success in the following breeding season. in house martins delichon urbica captured and studied at a breeding site in europe, we use ... | 2013 | 22961369 |
| prey selection by nesting house martins delichon urbica linné, 1758 (aves: hirundinidae) in algiers suburbs (algeria). | the diet of the house martin delichon urbica was analyzed in a suburban area in pins maritimes, northeast of algiers (algeria). the diet was determined by analyzing 120 faecal samples collected from a breeding colony between april and september 2007. insects were the most numerous prey types (99.86%). hymenopterans were the dominant preys (56.99%), followed by coleopterans (20.14%), homopterans (14.22%), heteropterans (5.45%), and dipterans (3.10%). division of the prey items into families demon ... | 2014 | 24439551 |
| isotopic analysis of island house martins delichon urbica indicates marine provenance of nutrients. | the presence of one of the largest colonies of house martins in europe on the small island of stora karlsö, sweden, led us to investigate the source of their food by analysis of stable isotopes of carbon and nitrogen. carbon isotopic values of house martin nestlings were the same as those of common guillemot uria aalge nestlings fed on marine fish, but differed from local collared flycatcher ficedula albicollis nestlings fed on woodland insects. we infer that these house martins fed their chicks ... | 2014 | 25866414 |
| solving a migration riddle using isoscapes: house martins from a dutch village winter over west africa. | the ability to connect breeding, stopover and wintering locations of populations of migratory birds greatly enhances our understanding of the phenomenon of migration and improves our chances of effectively conserving these species. among palearctic-afrotropical migratory species, aerial insectivores like the house martin (delichon urbicum) are sensitive to factors influencing the availability of flying insects, and have declined in recent decades. the strict aerial behaviour of martins severely ... | 2012 | 23028734 |
| stable isotope analysis provides new information on winter habitat use of declining avian migrants that is relevant to their conservation. | winter habitat use and the magnitude of migratory connectivity are important parameters when assessing drivers of the marked declines in avian migrants. such information is unavailable for most species. we use a stable isotope approach to assess these factors for three declining african-eurasian migrants whose winter ecology is poorly known: wood warbler phylloscopus sibilatrix, house martin delichon urbicum and common swift apus apus. spatially segregated breeding wood warbler populations (samp ... | 2012 | 22496827 |
| functional invertebrate prey groups reflect dietary responses to phenology and farming activity and pest control services in three sympatric species of aerially foraging insectivorous birds. | farming activity severely impacts the invertebrate food resources of farmland birds, with direct mortality to populations of above-ground arthropods thorough mechanical damage during crop harvests. in this study we assessed the effects of phenological periods, including the timing of harvest, on the composition and biomass of prey consumed by three species of aerial insectivorous birds. common swifts apus apus, barn swallows hirundo rustica and house martins delichon urbica breed sympatrically a ... | 2014 | 25506696 |
| variable contribution of functional prey groups in diets reveals inter- and intraspecific differences in faecal concentrations of essential and non-essential elements in three sympatric avian aerial insectivores: a re-assessment of usefulness of bird faeces in metal biomonitoring. | aerial insectivores through their insect diet can contribute to biotransfer of elements across habitats. we investigate the relationship between dietary composition as expressed by the contributions of six functional invertebrate prey groups (primarily of agriculturally subsidised invertebrates characteristic of agricultural areas in temperate regions of europe) and concentrations of essential (na, k, ca, mg, fe, cu, zn, mn, co) and non-essential (as, cd, pb) elements of environmental concern in ... | 2015 | 25770953 |
| development of trypanosoma everetti in culicoides biting midges. | trypanosoma species (trypanosomatida, kinetoplastea) are almost exclusively heteroxenous flagellated parasites, which have been extensively studied as the causative agents of severe trypanosomiasis in humans and domestic animals. however, the biology of avian trypanosomes remains insufficiently known, particularly in wildlife, despite information that some species might be pathogenic and affect the fitness of intensively infected individuals. avian trypanosomes are cosmopolitans. due to regular ... | 2020 | 32473117 |
| fueling of a marine-terrestrial ecosystem by a major seabird colony. | seabirds redistribute nutrients between different ecosystem compartments and over vast geographical areas. this nutrient transfer may impact both local ecosystems on seabird breeding islands and regional biogeochemical cycling, but these processes are seldom considered in local conservation plans or biogeochemical models. the island of stora karlsö in the baltic sea hosts the largest concentration of piscivorous seabirds in the region, and also hosts a large colony of insectivorous house martins ... | 2020 | 32963305 |
| [oeciacus hirundinis from the nests of the swallows delichon urbica and hirundo rustica]. | in the years 1976-1989 392 nests of d. urbica and 584 nests of h. rustica were collected from 54 localities in 6 provinces in the north of poland. the highest mean number of specimens per nest was observed in the nest of d. urbica (28.4) and the lowest in nest of h. rustica (4.2). the highest percentage of nests of the swallows with oe. hirundinis was recorded in december and lowest in march. the highest mean number of oe. hirundinis per nest was in the nest of d. urbica in august and lowest in ... | 1991 | 1822044 |
