| light-dependent magnetoreception in birds: increasing intensity of monochromatic light changes the nature of the response. | the radical pair model proposes that magnetoreception is a light-dependent process. under low monochromatic light from the short-wavelength part of the visual spectrum, migratory birds show orientation in their migratory direction. under monochromatic light of higher intensity, however, they showed unusual preferences for other directions or axial preferences. to determine whether or not these responses are still controlled by the respective light regimes, european robins, erithacus rubecula, we ... | 2007 | 17302975 |
| ticks (ixodidae) from passerine birds in the carpathian region. | birds have been found to be a reservoir host of borrelia. in order to assess the situation in slovakia ticks were collected from a total of 3057 mist-netted, ringed and released passerine birds in two locations at 500 m (in 2001) and 1000 m (in 2003) above sea level in the bukovské vrchy hills, part of the carpathian region in the north-east of slovakia. a total of 75 birds of 16 species were infested with subadult ticks of ixodes ricinus species (prevalence of parasitization 5%). sixty-two larv ... | 2006 | 17186172 |
| where in europe should we look for sources of the cutaneous trematode collyriclum faba infections in migrating birds? | cutaneous cysts with trematodes of collyriclum faba have been found in birds during their spring and post-breeding migrations in the czech republic. during spring migrations, c. faba was found in one dunnock prunella modularis, two european robins erithacus rubecula, three common nightingales luscinia megarhynchos, one song thrush turdus philomelos and one great reed warbler acrocephalus arundinaceus. during post-breeding migration, the same parasite was found in one garden warbler sylvia borin, ... | 2006 | 17125543 |
| redescriptions of monosertum parinum (dujardin, 1845) and m. mariae (mettrick, 1958) n. comb. from european passerine birds, with an amended generic diagnosis of monosertum bona, 1994 (cestoda: dilepididae). | the type-species of monosertum bona, 1994, m. parinum (dujardin, 1845), is redescribed on the basis of the neotype designated by bona (1994). m. mariae (mettrick, 1958) n. comb. (originally paricterotaenia mariae mettrick, 1958) is recorded and redescribed from erithacus rubecula l. (passeriformes: turdidae) in the kaliningradskaya oblast', russia (new geographical record). an amended generic diagnosis of monosertum is presented. | 2007 | 17120137 |
| vortex wakes generated by robins erithacus rubecula during free flight in a wind tunnel. | the wakes of two individual robins were measured in digital particle image velocimetry (dpiv) experiments conducted in the lund wind tunnel. wake measurements were compared with each other, and with previous studies in the same facility. there was no significant individual variation in any of the measured quantities. qualitatively, the wake structure and its gradual variation with flight speed were exactly as previously measured for the thrush nightingale. a procedure that accounts for the dispa ... | 2006 | 16849236 |
| two different types of light-dependent responses to magnetic fields in birds. | a model of magnetoreception proposes that the avian magnetic compass is based on a radical pair mechanism, with photon absorption leading to the formation of radical pairs. analyzing the predicted light dependency by testing migratory birds under monochromatic lights, we found that the responses of birds change with increasing intensity. the analysis of the orientation of european robins under 502 nm turquoise light revealed two types of responses depending on light intensity: under a quantal fl ... | 2005 | 16111946 |
| spatial behavior of medium and long-distance migrants at stopovers studied by radio tracking. | spatial behavior and range of movements at daytime stopovers of three species of passerine nocturnal migrants (european robins, sedge warbler, and pied flycatchers) were studied by radio tracking. both in spring and in fall, 94% of european robins remained within 350-400 m of their landing location (n = 51 and 65, respectively). movements of robins became more area-restricted with more time spent at stopover. sedge warblers never moved more than 335 m (n = 12). a reason for this could be their r ... | 2005 | 16055857 |
| vertebrate host specificity of two avian malaria parasites of the subgenus novyella: plasmodium nucleophilum and plasmodium vaughani. | the susceptibility of wild-caught european passeriform birds to naturally isolated malaria parasites, plasmodium (novyella) nucleophilum and plasmodium (novyella) vaughani, was studied by means of intramuscular subinoculation of infected citrated blood. plasmodium nucleophilum of the great tit, parus major, was transmitted to 3 great tits, but 3 blackcaps (sylvia atricapilla) were not susceptible. plasmodium vaughani of the robin, erithacus rubecula, was transmitted to 1 robin and 1 blackcap, bu ... | 2005 | 15986631 |
| magnetic compass orientation of migratory birds in the presence of a 1.315 mhz oscillating field. | the radical pair model of magnetoreception predicts that magnetic compass orientation can be disrupted by high frequency magnetic fields in the megahertz range. european robins, erithacus rubecula, were tested under monochromatic 565 nm green light in 1.315 mhz fields of 0.48 microt during spring and autumn migration, with 1.315 mhz being the frequency that matches the energetic splitting induced by the local geomagnetic field. the birds' responses depended on the alignment of the oscillating fi ... | 2004 | 15614508 |
| retinal cryptochrome in a migratory passerine bird: a possible transducer for the avian magnetic compass. | the currently discussed model of magnetoreception in birds proposes that the direction of the magnetic field is perceived by radical-pair processes in specialized photoreceptors, with cryptochromes suggested as potential candidate molecules mediating magnetic compass information. behavioral studies have shown that magnetic compass orientation takes place in the eye and requires light from the blue-green part of the spectrum. cryptochromes are known to absorb in the same spectral range. because o ... | 2004 | 15551029 |
| learning fine-tunes a specific response of nestlings to the parental alarm calls of their own species. | parent birds often give alarm calls when a predator approaches their nest. however, it is not clear whether these alarms function to warn nestlings, nor is it known whether nestling responses are species-specific. the parental alarms of reed warblers, acrocephalus scirpaceus ("churr"), dunnocks, prunella modularis ("tseep"), and robins, erithacus rubecula ("seee") are very different. playback experiments revealed that nestlings of all three species ceased begging only in response to conspecific ... | 2004 | 15539356 |
| optimal stopover decisions of migrating birds under variable stopover quality: model predictions and the field data. | dataset on departure fuel loads, stopover length and fuel deposition rate of the european robins erithacus rubecula during their migration in the baltic area is presented. we test these empirical data against the predictions of an optimal migration model assuming that robins minimize time spent on migration, and that fuel deposition rate varies stochastically. the latter assumption sets this model apart from the alternative ones and makes it more realistic. in particular, it is applicable in fre ... | 2006 | 15329011 |
| light-dependent magnetoreception in birds: interaction of at least two different receptors. | passerine migrants require light from the blue-green part of the spectrum for magnetic compass orientation; under yellow light, they are disoriented. european robins tested under a combination of yellow light and blue or green light showed a change in behavior, no longer preferring their seasonally appropriate migratory direction: in spring as well as in autumn, they preferred southerly headings under blue-and-yellow and northerly headings under green-and-yellow light. this clearly shows that ye ... | 2004 | 15034663 |
| light-dependent magnetoreception in birds: analysis of the behaviour under red light after pre-exposure to red light. | in previous experiments, migratory birds had been disoriented under 635 nm red light, apparently unable to use their magnetic compass. the present study with european robins, erithacus rubecula, confirms these findings for red light at the levels of 6 x 10(15) quanta s(-1) m(-2) and 43 x 10(15) quanta s(-1) m(-2), suggesting that the disorientation under red light was not caused by the test light being below the threshold for magnetoreception. however, pre-exposure to red light for 1 h immediate ... | 2004 | 14978060 |

| cutaneous trematode collyriclum faba in wild birds in the central european carpathians. | the occurrence of cutaneous trematode collyriclum faba in wild birds was monitored in the central european carpathians from 1996 to 2001. a total of 5,414 birds, representing 86 species, was examined. collyriclum faba was found at 7 sites (5 in slovakia, 1 in poland, and 1 in the czech republic), and prevalences at the sites varied from 1 to 16%. ten species of passerine birds were infected: blackcap (sylvia atricapilla) (16 positive/622 tested, 2% prevalence), black redstart (phoenicurus ochrur ... | 2003 | 12760670 |
| magnetic compass orientation in european robins is dependent on both wavelength and intensity of light. | magnetic compass orientation in birds has been shown to be light dependent. results from behavioural studies indicate that magnetoreception capabilities are disrupted under light of peak wavelengths longer than 565 nm, and shifts in orientation have been observed at higher light intensities (43-44x10(15) quanta s(-1) m(-2)). to investigate further the function of the avian magnetic compass with respect to wavelength and intensity of light, we carried out orientation cage experiments with juvenil ... | 2002 | 12432008 |
| prevalence of borrelia burgdorferi sensu lato in the nightingale (luscinia megarhynchos) and other passerine birds. | in order to explore the involvement of terrestrial birds in the ecology of lyme disease spirochetes, we determined the presence of borrelia burgdorferi s. i. dna in tick larvae feeding on the hosts. birds were caught at several study sites along the rhine valley in sw germany between august 1999 and march 2001. a total of 987 ixodes ricinus larvae were collected from 225 birds belonging to 20 host species. the following four passerine species that have not yet been subject to detailed reservoir ... | 2002 | 12141765 |
| magnetic compass orientation of european robins under 565 nm green light. | european robins tested under monochromatic green light with a peak wavelength of 565 nm at an intensity of 2.1 mw m-2 in the local geomagnetic field preferred their migratory direction, heading southward in autumn and northward in spring. inverting of the vertical component of the magnetic field caused the robins to reverse their headings, indicating that the birds used a magnetic inclination compass to locate their migratory direction. the behavior recorded under green light at an intensity of ... | 2001 | 11688414 |
| light-dependent magnetoreception in birds: the behaviour of european robins, erithacus rubecula, under monochromatic light of various wavelengths and intensities. | to investigate how magnetoreception is affected by the wavelength and intensity of light, we tested european robins, erithacus rubecula, under monochromatic lights of various wavelengths at two intensities using oriented behaviour as an indicator of whether the birds could derive directional information from the geomagnetic field. at a quantal flux of 7 x 10(15) quanta s(-1) m(-2), the birds were well oriented in their migratory direction east of north under 424 nm blue, 510 nm turquoise and 565 ... | 2001 | 11606603 |
| postexercise ketosis in night-migrating passerine birds. | this study investigated the postexercise metabolism of six species of free-living, night-migrating passerine birds (european robin, pied flycatcher, wheatear, redstart, blackcap, and garden warbler). the birds were caught during autumn migration out of their nocturnal flight, and their metabolism changed from a fasting, highly active state to a fasting, resting state. concentrations of six plasma metabolites of the fat, carbohydrate, and protein metabolism were measured during up to 10 h of reco ... | 2001 | 11226017 |
| a mathematical expectation model for bird navigation based on the clock-and-compass strategy. | we present here a mathematical formula for the directional distribution of migratory birds if they use a vector navigation/clock-and-compass strategy to find their winter quarters. it is based on mathematical expectation theory and shows that a simple parabola can describe the expected geographical spread of clock-and-compass birds as a function of migratory distance. predictions based on this model are then tested against all same autumn ringing recoveries of first-season pied flycatchers, fice ... | 2000 | 11034834 |
| territoriality as a paternity guard in the european robin, erithacus rubecula. | to investigate the relative importance of paternity defences in the european robin we used behavioural observations, simulated intrusions and temporary male removal experiments. given that paired males did not increase their mate attendance, copulation rate or territory size during the female's fertile period, the most frequently quoted paternity assurance strategies in birds were absent. however, males with fertile females sang and patrolled their territories more regularly, suggesting that ter ... | 2000 | 10973717 |
| strategic diel regulation of body mass in european robins. | stochastic dynamic programming (sdp) is a computational technique that has been used to model daily routines of foraging in small birds. a diurnal bird must build up its fat reserves towards dusk in order to avoid starvation during the night, when it cannot feed. however, as well as the benefits of avoiding starvation, storing fat imposes costs such as an increased predation risk and higher flight and metabolic costs. there is therefore an optimal level of fat reserves for a bird to reach at dus ... | 2000 | 10792933 |
| entomologic and avian investigations of an epidemic of west nile fever in romania in 1996, with serologic and molecular characterization of a virus isolate from mosquitoes. | between july and october 1996, a west nile (wn) fever epidemic occurred in the southern plain and danube valley of romania and in the capital city of bucharest, resulting in hundreds of neurologic cases and 17 fatalities. in early october 1996, entomologic and avian investigations of the epidemic were conducted in the city of bucharest and nearby rural areas. thirty (41%) of 73 domestic fowl sampled had neutralizing antibody to wn virus, including 5 of 13 ducks (38%), 1 of 1 goose, 19 of 52 chic ... | 1999 | 10548295 |
| feather mites, pectoral muscle condition, wing length and plumage coloration of passerines. | i compared the feather mite (acari, proctophyllodidae) loads of moulting birds with features of the new plumage that they were growing. i examined 21 samples, each sample containing individuals of the same species, sex and age class (juvenile, yearling or adult). i used nine species: wren, troglodytes troglodytes; dunnock, prunella modularis; robin, erithacus rubecula; blue tit, parus caeruleus; great tit, p. major; chaffinch, fringilla coelebs; greenfinch, carduelis chloris; linnet, c. cannabin ... | 1999 | 10479371 |
| the effect of variability in the food supply on the daily singing routines of european robins: a test of a stochastic dynamic programming model. | a stochastic dynamic programming (sdp) model offers a general explanation of daily singing routines in birds, but remains almost untested empirically. i examined a central prediction of the sdp model, that a more variable food supply decreases the bird's song output at dawn, relative to its song output at dusk. i provided supplementary food to make the food supply more or less variable over 2-week periods in the territories of free-living european robins erithacus rubecula. robins sang relativel ... | 1999 | 10049476 |
| two tests of a stochastic dynamic programming model of daily singing routines in birds. | many hypotheses have been put forward to account for the dawn chorus in birds. few of these, however, are able to account for variation in song output over the whole day, or for differences in daily singing routines between species, individuals, seasons and environmental conditions. one hypothesis that does offer a more general explanation is based on a stochastic dynamic programming (sdp) model of daily singing routines. this model relates the relative costs and benefits of feeding and singing ... | 1999 | 10049466 |
| nestling mouth colour: ecological correlates of a begging signal. | the mouths of begging nestlings vary widely in colour, ranging from yellow in robins, erithacus rubecula, to red in reed buntings, emberiza schoeniclus. two functions have been suggested for bright nestling mouth colour: (1) it may improve the detectability of chicks, particularly in poorly lit nests and (2) within species, it may signal need. we tested these hypotheses in a comparative analysis, measuring the mouth colours of nestlings from 31 species under conditions of standardized light avai ... | 1998 | 9784220 |
| serum "b" esterases as a nondestructive biomarker for monitoring the exposure of reptiles to organophosphorus insecticides. | a field study was conducted to validate serum b esterases as nondestructive biomarkers (ndbs) in lizards. serum butyrylcholinesterase (bche) and carboxylesterase (cbe) activities were measured in lizards and four species of birds collected in an area of 0.5 ha sprayed with 0.36 kg a.i./ha of folidol se5 (5% parathion). serum b esterase activities were determined in a total of 213 lizards (gallotia galloti) and 81 birds of four species (sylvia melanocephala, serinus canaria, parus caeruleus, and ... | 1997 | 9352213 |

| asymmetric territorial contests in the european robin: the role of settlement costs | a widespread feature of territorial systems is that residents almost invariably defeat challengers. this phenomenon has been explained by the existence of value asymmetries, variations in resource-holding potential or an 'owners always win' convention. removal-replacement experiments were performed on 75 robins, erithacus rubeculato test these hypotheses. the settling behaviour of newcomers was also examined in order to identify energetic costs incurred during territory establishment. in winter, ... | 1997 | 9268431 |
| borreliae in immature ixodes ricinus (acari:ixodidae) ticks parasitizing birds in the czech republic. | of 411 forest birds of 33 species examined near valtice, czech republic, 29% were infested with ixodes ricinus (l.); 2.2% were parasitized by haemaphysalis concinna koch. borreliae were detected in 5.1 and 11.7% of larval and nymphal i. ricinus, respectively. none of the 13 h. concinna tested was infected. in total, 3.2% of the birds examined were parasitized by i. ricinus immatures infected by borreliae. borreliae-containing ticks parasitized european robin, erithacus rubecula (l.); eurasian bl ... | 1996 | 8840682 |
| ixodes ricinus immatures on birds in a focus of lyme borreliosis. | the infestation of birds by immature ixodes ricinus was studied during 6 months in a swiss woodland, where lyme borreliosis is endemic. thirteen passerine species were found to be parasitized by i. ricinus subadults and specially turdus merula, t. philomelos and erithacus rubecula. overall, 300 larvae and 162 nymphs were collected on 95 avian hosts. prevalence of infestation of nymphs on birds was higher in spring; larvae peaked in summer. the infection of birds by borrelia burgdorferi was also ... | 1993 | 8314179 |
| possible role of birds and ticks in the dissemination of bhanja virus. | several wild birds (4 fringilla coelebs, 1 coccothraustes coccothraustes and 2 erithacus rubecula) were inoculated subcutaneously with bhanja virus (bhav). no clinical symptoms of infection were observed in any of the birds; a low viremia was demonstrated only in c. coccothraustes (2 and 4 days p.i.), seroconversion in all birds. bhav was not isolated from organs 32 days p.i. consequently, the tested birds do not seem to serve as "amplifying hosts" of bhav. the paper includes a survey of geograp ... | 1982 | 6800906 |

| deuterium and oxygen-18 abundance in birds: implications for dlw energetics studies. | the doubly labeled water (dlw) technique for measuring energy expenditure may employ one (18o) or two (18o and deuterium) stable isotopes as tracers. these occur naturally in the environment, so when they are used as tracers it is necessary to subtract the background levels. few studies report data on background concentrations. this work provides such data for a range of avian species. overall, there was a strong positive correlation (r = 0.63) between the 18o and deuterium concentrations in bir ... | 1990 | 2316726 |
| territorial aggression and song of male european robins (erithacus rubecula) in autumn and spring: effects of antiandrogen treatment. | male robins aggressively defending a feeding territory in winter have low levels of testosterone, while males defending a breeding territory in spring have elevated levels of testosterone. song is an integrated part of territorial defense during both phases. we investigated whether testosterone is involved in the expression of these behaviors by treating free-living and captive male robins during both phases with the antiandrogen flutamide. results suggest that, similar to species in which terri ... | 1991 | 2066079 |
| [trematodes of birds from lower silesia. iii. urotocus rossitensis (mühling, 1898)--new for poland species of trematode parasitism in passeriform birds]. | during the studies on trematode fauna of birds from lower silesia, the rare species--urotocus rossitensis (mühling, 1898)--was found. it parasitized in the bursa fabricii of sylvia borin, erithacus rubecula and turdus philomelos, and in the cloaca of turdus merula. all these birds are new hosts for u. rossitensis which was recorded for the first time in poland. it is worth mentioning that the localization of this trematode in the cloaca of t. merula is nontypical, since the parasite has underdev ... | 1991 | 1844788 |
