An acoustic postconflict display in the duetting tropical boubou (Laniarius aethiopicus): a signal of victory? (1/549)

BACKGROUND: In many species of birds, pair bonded males and females precisely co-ordinate their vocalisations to form duets. Duetting behaviour, although still somewhat of an enigma, is thought to function primarily in territorial defence and mate guarding. We identify an additional function of duetting in an afrotropical bird, the tropical boubou (Laniarius aethiopicus), that uses one duet type as a postconflict display probably to advertise victory to other boubous. RESULTS: We simulated intrusions into boubou territories in the field in Ivory Coast, West Africa using playbacks of four different types of boubou duets to test the use of the presumptive acoustic victory display before, during and after playbacks. These staged encounters resulted in either retreat of the focal birds during playback or continued presence accompanied by vocal displays after playback had ceased. Losers of encounters never sung after retreating whereas 11 out of 18 pairs sung the presumptive victory duet after the encounter. Analysis revealed that the presumptive victory display was sung significantly more often after than before or during the playback treatment. CONCLUSION: We conclude that, most likely, the investigated duet type is a postconflict victory display - a novel function of duets. Furthermore the duet is a rare example among birds of a context-specific song. The conspicuousness of the display suggests that it is directed not only to losers of an agonistic encounter but also to other pairs of birds in neighbouring territories.  (+info)

Phylogenetic relationships of typical antbirds (Thamnophilidae) and test of incongruence based on Bayes factors. (2/549)

BACKGROUND: The typical antbirds (Thamnophilidae) form a monophyletic and diverse family of suboscine passerines that inhabit neotropical forests. However, the phylogenetic relationships within this assemblage are poorly understood. Herein, we present a hypothesis of the generic relationships of this group based on Bayesian inference analyses of two nuclear introns and the mitochondrial cytochrome b gene. The level of phylogenetic congruence between the individual genes has been investigated utilizing Bayes factors. We also explore how changes in the substitution models affected the observed incongruence between partitions of our data set. RESULTS: The phylogenetic analysis supports both novel relationships, as well as traditional groupings. Among the more interesting novel relationship suggested is that the Terenura antwrens, the wing-banded antbird (Myrmornis torquata), the spot-winged antshrike (Pygiptila stellaris) and the russet antshrike (Thamnistes anabatinus) are sisters to all other typical antbirds. The remaining genera fall into two major clades. The first includes antshrikes, antvireos and the Herpsilochmus antwrens, while the second clade consists of most antwren genera, the Myrmeciza antbirds, the "professional" ant-following antbirds, and allied species. Our results also support previously suggested polyphyly of Myrmotherula antwrens and Myrmeciza antbirds. The tests of phylogenetic incongruence, using Bayes factors, clearly suggests that allowing the gene partitions to have separate topology parameters clearly increased the model likelihood. However, changing a component of the nucleotide substitution model had much higher impact on the model likelihood. CONCLUSIONS: The phylogenetic results are in broad agreement with traditional classification of the typical antbirds, but some relationships are unexpected based on external morphology. In these cases their true affinities may have been obscured by convergent evolution and morphological adaptations to new habitats or food sources, and genera like Myrmeciza antbirds and the Myrmotherula antwrens obviously need taxonomic revisions. Although, Bayes factors seem promising for evaluating the relative contribution of components to an evolutionary model, the results suggests that even if strong evidence for a model allowing separate topology parameters is found, this might not mean strong evidence for separate gene phylogenies, as long as vital components of the substitution model are still missing.  (+info)

Renal function in Palestine sunbirds: elimination of excess water does not constrain energy intake. (3/549)

Although the renal responses of birds to dehydration have received significant attention, the consequences of ingesting and processing large quantities of water have been less studied. Nectar-feeding birds must often deal with exceptionally high water intake rates in order to meet their high mass-specific energy demands. Birds that ingest large volumes of water may either eliminate excess water in the kidney or regulate the volume of water absorbed in the gastrointestinal tract. Because water absorption in the gastrointestinal tract of Palestine sunbirds (Nectarinia osea) decreases with increasing water ingestion rate, we predicted that glomerular filtration rate (GFR) in these birds would not be unusually high in spite of large ingested water loads. When feeding on dilute sucrose solutions, sunbirds ingested between 4 and 6 times their body mass in nectar per day, yet they were able to compensate for varying nectar energy density and increased thermoregulatory energy demands with no apparent difficulty. GFR was lower than predicted (1976.22+/-91.95 microl h(-1)), and was not exceptionally sensitive to water loading. Plasma glucose concentrations were high, and varied 1.8-fold between fasted (16.08+/- 0.75 mmol l(-1)) and fed (28.18+/-0.68 mmol l(-1)) sunbirds, but because GFR was low, glucose filtered load also remained relatively low. Essentially the entire glucose filtered load (98%) was recovered by the kidney. Renal fractional water reabsorption (FWR) decreased from 0.98 to 0.64 with increasing water intake. The ability of Palestine sunbirds to reduce the absorption of ingested water in the gastrointestinal tract may resolve the potential conflict between filtering a large excess of absorbed water in the kidney and simultaneously retaining filtered metabolites.  (+info)

Comparison of the cost of short flights in a nectarivorous and a non-nectarivorous bird. (4/549)

Although most birds are accustomed to making short flights, particularly during foraging, the flight patterns during these short periods of activity differ between species. Nectarivorous birds, in particular, often spend time hovering, while non-nectarivorous birds do not. The cost of short flights is likely therefore to differ between nectarivorous and non-nectarivorous birds because of the different energetic contributions of different flight types to the behaviour. The 13C-labelled bicarbonate technique was used to measure the energy cost of short flights in the nectarivorous Palestine sunbird Nectarinia osea (mean mass 6.17+/-0.16 g, N=8) and the non-nectarivorous starling Sturnus vulgaris (mean mass 70.11+/-1.11 g, N=9). The technique was initially calibrated in five individuals for each species at temperatures ranging from 1 to 35 degrees C, by comparing the isotope elimination rate to the metabolic rate measured simultaneously by indirect calorimetry. The cost for short intermittent flight was then measured by encouraging birds to fly between two perches at either end of a narrow corridor (perch distance for sunbirds, 6 m; for starlings, 5 m), and measuring the amount of isotope eliminated during the flight. The isotope elimination rate was interpolated onto the calibration equation to predict flight cost, as a direct calibration could not be performed during flight. Mean energy expenditure during flight was 1.64+/-0.32 W in sunbirds, while in starlings the flight costs averaged 20.6+/-0.78 W. Energy cost of flight relative to basal metabolic rate was substantially greater in the starling than the sunbird. Phylogenetic analysis of different modes of flight in these and additional species suggests that differences in flight behaviour may cause these elevated costs in slow flying non-nectarivores such as starlings, compared to birds that are more prone to short intermittent flights like the sunbirds.  (+info)

Year-round West Nile virus activity, Gulf Coast region, Texas and Louisiana. (5/549)

West Nile virus (WNV) was detected in 11 dead birds and two mosquito pools collected in east Texas and southern Louisiana during surveillance studies in the winter of 2003 to 2004. These findings suggest that WNV is active throughout the year in this region of the United States.  (+info)

Sound localization in a small passerine bird: discrimination of azimuth as a function of head orientation and sound frequency. (6/549)

Sound localization is critical to communication when signalers are distributed widely in space and when reverberations that accumulate over distance might otherwise degrade temporal patterns in vocalizations. We readdress the accuracy with which a small passerine bird, the eastern towhee, Pipilo erythrophthalmus L., is able to resolve azimuth in the field. We then report results from two-alternative forced-choice (2AFC) experiments in which three of four subjects were able to discriminate an estimated speaker separation angle of approximately 7 degrees . Subjects oriented laterally when discriminating azimuth in the 2AFC task and each subject preferred a different head orientation. Side biases occurred as a function of head orientation and, as a consequence, we conducted a second 2AFC experiment in which subjects were required to discriminate between two closely spaced lights. Subjects oriented similarly in this visual task, however, side biases did not occur as a function of head orientation. Despite side biases in the auditory task, performance generally declined when subjects were played tones with frequencies near approximately 3 kHz.  (+info)

Nutritional bias as a new mode of adjusting sex allocation. (7/549)

Sex biases in the allocation of resources to offspring occur in a broad range of taxa. Parents have been shown to achieve such biases either by producing numerically more of one sex or by providing the individuals of one sex with a greater quantity of resources. In addition, skews in allocation could occur if the offspring of one sex receive resources of higher quality (greater nutritional or energetic value by weight or volume), although this mode of adjustment has, to our knowledge, never been demonstrated. We compared the types of prey and the metabolizable energy provisioned to male and female nestlings in one of the most sexually size dimorphic of all birds, the brown songlark, Cinclorhamphus cruralis. Within broods, we found that males not only received more prey than their smaller sisters, but also prey of apparently higher quality. This dietary disparity could result either from mothers actively discriminating between the sexes when providing prey or from competition among siblings. We suggest that sex differences in offspring diet quality may occur in a wide range of other taxa and function as an additional mechanism of sex allocation adjustment.  (+info)

Melyrid beetles (Choresine): a putative source for the batrachotoxin alkaloids found in poison-dart frogs and toxic passerine birds. (8/549)

Batrachotoxins are neurotoxic steroidal alkaloids first isolated from a Colombian poison-dart frog and later found in certain passerine birds of New Guinea. Neither vertebrate group is thought to produce the toxins de novo, but instead they likely sequester them from dietary sources. Here we describe the presence of high levels of batrachotoxins in a little-studied group of beetles, genus Choresine (family Melyridae). These small beetles and their high toxin concentrations suggest that they might provide a toxin source for the New Guinea birds. Stomach content analyses of Pitohui birds revealed Choresine beetles in the diet, as well as numerous other small beetles and arthropods. The family Melyridae is cosmopolitan, and relatives in Colombian rain forests of South America could be the source of the batrachotoxins found in the highly toxic Phyllobates frogs of that region.  (+info)

Cyanistes is a genus of birds in the tit family Paridae. The genus was at one time considered as a subgenus of Parus. In 2005 an article describing a molecular phylogenetic study that had examined mitochondrial DNA sequences from members of the tit family, proposed that a number of subgenera including Cyanistes be elevated to genus status. This proposal was accepted by International Ornithologists Union and the British Ornithologists Union. The genus contains three species: Eurasian blue tit, Cyanistes caeruleus African blue tit, Cyanistes teneriffae Azure tit, Cyanistes cyanus Yellow-breasted tit, Cyanistes cyanus flavipectus The name Cyanistes was introduced for the subgenus by the German naturalist Jakob Kaup in 1829. The word comes from the classical Greek kuanos meaning dark-blue. Gill, F.B.; Slikas, B.; Sheldon, F.H. (2005). Phylogeny of titmice (Paridae): II.

Many seasonal breeders adjust the timing of reproduction in response to year-to-year variations in supplementary environmental cues, amongst which ambient temperature is thought to be most influential. However, it is possible that for species such as the great tit (Parus major L.), phenological cues from sprouting vegetation and the consequent abundance of invertebrate prey, although dependent on temperature, may provide supplementary environmental cues per se. This hypothesis was investigated in breeding pairs of great tits kept in outdoor aviaries. In spring, experimental pairs were provided with access to leafing birch branches and caterpillars as a visual food cue, while control pairs were provided with non-leafing branches. Observations were made on the onset of laying and on concentrations of plasma luteinizing hormone (LH) at regular intervals to monitor changes in reproductive function. The onset of egg laying was not advanced by the presence of leafing branches and caterpillars. LH ...
The subjects of this experiment were eight (four males and four females) sexually mature hand-raised western scrub-jays that had prior experience with the cache-recovery paradigm. The birds were housed in pairs in cages measuring 2 m wide × 1 m deep × 1 m high, and were maintained inside on a 12 L : 12 D cycle on a maintenance diet supplemented with nuts, seeds, dog biscuits, various fruits, wax worms and meal worms. The maintenance diet was removed from the home cage 2 h before an experimental trial, ensuring that the jays were mildly hungry during caching. All the caching trials took place in the cachers home cage and jays were provided with 50 waxworms. The jays could be separated by cage dividers, placing each jay into a 1 m × 1 m × 1 m compartment of the home-cage for testing.. During the alone condition, all but the experimental birds were removed from the home-cages in the room and placed in a near-by aviary, and the test bird could see all the remaining empty cages. In the seen ...
Data were collected in 2001 in a population of blue and great tits breeding in eastern France (48°17′N, 4°18′E). The blue tit Parus caeruleus (Linnaeus 1758) and great tit Parus major (Linnaeus 1758) are small (i.e. adult body mass of 11 g and 19 g, respectively) hole-nesting passerines often living in the same wooded areas and that are in competition for access to breeding sites and for food (Gosler, 1993). Both species lay large clutches (i.e. generally more than seven eggs), although blue tit females lay on average more eggs than great tit females (Blondel et al., 1990; Newton, 1989). Nestlings of both species have a similar diet of arthropods, mainly lepidopteran larvae and spiders (Minot, 1981). The study area (about 250 ha) contained 400 nestboxes evenly distributed among a homogenous deciduous old woodland composed mainly of oak (Quercus spp.), hornbeam (Carpinus betulus) and beech (Fagus sylvatica). Nests were regularly inspected to determine laying date, clutch size, start date of ...
BackgroundAvian keratin disorder (AKD) is an epizootic of debilitating beak deformities, first documented in black-capped chickadees (Poecile atricapillus) in Alaska during the late 1990s. Similar deformities have now been recorded in dozens of species of birds across multiple continents. Despite this, the etiology of AKD has remained elusive, making it difficult to assess the impacts of this disease on wild populations. We previously identified an association between infection with a novel picornavirus, Poecivirus, and AKD in a small cohort of black-capped chickadees.MethodsTo test if the association between Poecivirus and AKD holds in a larger study population, we used targeted PCR followed by Sanger sequencing to screen 124 symptomatic and asymptomatic black-capped chickadees for Poecivirus infection. We further compared the efficacy of multiple non-terminal field sampling methods (buccal swabs, cloacal swabs, fecal samples, and blood samples) for Poecivirus screening. Finally, we used both in situ

Common Name: Blue Tit Scientific Name: Cyanistes caeruleus Size: 4 ½ to 5 inches (12cm) Habitat: Eurasia and Africa; Found in Europe, Near East, Northwest Africa. Lives in woodland and scrub areas and in urban settings. Status: Least Concern. Global Population: 10,000,000 Mature individuals. Throughout Europe, the populations have been increasing since 1980. Diet: Insect and spiders, also fruit and seeds in winter Breeding: Eight to ten eggs in hole in a tree and nest box. Pairs will return to the same nesting area year after year. Cool Facts: The Blue Tit is considered a valuable destroyer of pests, although it has not an entirely a beneficial species. It is fond of young buds of various trees, and may pull them to bits in the hope of finding insects, thus destroying the flower and fruit of the tree. But no species in Europe destroys more coccids and aphids, leaf miner grubs and green tortrix moths. An interesting example of culturally transmitted learning in birds was the phenomenon dating ...
Although trade-offs between reproductive effort and other fitness components are frequently documented in wild populations, the underlying physiological mechanisms remain poorly understood. Parasitism has been suggested to mediate reproductive trade-offs, yet only a limited number of parasite taxa have been studied, and reproductive effort-induced changes in parasitism are rarely linked to trade-offs observed in the same population. We conducted a brood size manipulation experiment in blue tits (Cyanistes caeruleus) infected with malaria (Plasmodium) parasites, and used quantitative PCR to measure changes in parasitaemia. In one of two years investigated, parasitaemia increased as a result of brood enlargement, and was also positively associated with two other indicators of reproductive effort: clutch size and single parenthood. These associations between both experimental and naturally varying reproductive effort and parasitaemia suggest that immune control of chronic malaria infections can be
Chickadees are one of the easiest birds to attract to feeders, for suet, sunflower, and peanuts. They dont mind using tiny hanging feeders that swing in the wind, and also readily visit window feeders. Planting willow, alder, and birch trees provides future nesting habitat for chickadees. Find out more about what this bird likes to eat and what feeder is best by using the Project FeederWatch Common Feeder Birds bird list.. Feeders and nest boxes are often used by chickadees; consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and young. Black-capped Chickadees are especially attracted to a box when it is filled with sawdust or wood shavings. To keep wrens out of boxes you want chickadees to nest in, place nest boxes at least 60 feet into a wooded area. The compass orientation of the entrance hole probably does not matter at all, but chickadees do seem to prefer an unobstructed path to ...
The timing of reproduction varies from year to year in many bird species. To adjust their timing to the prevailing conditions of that year, birds use cues from their environment. However, the relative importance of these cues, such as the initial predictive (e. g. photoperiod) and the supplemental factors (e. g. temperature), on the seasonal sexual development are difficult to distinguish. In particular, the fine-tuning effect of temperature on gonadal growth is not well known. One way temperature may affect timing is via its strong effect on energy expenditure as gonadal growth is an energy-demanding process. To study the interaction of photoperiod and temperature on gonadal development, we first exposed 35 individually housed male great tits (Parus major) to mid-long days (after 6 weeks of 8h L:16 h D at 15 degrees C, photoperiod was set to 13h L:11 h D at 15 degrees C). Two weeks later, for half of the males the temperature was set to 8 degrees C, and for the other half t! o 22 degrees C. ...
article{9e9eb8dd-ba7d-45ae-a439-5616e3167fe9, abstract = {The hormone corticosterone (CORT) is an important component of a birds response to environmental stress, but it can also have negative effects. Therefore, birds on migration are hypothesized to have repressed stress responses (migration-modulation hypothesis). In contrast to earlier studies on long-distance migrants, we evaluate this hypothesis in a population containing both migratory and resident individuals. We use a population of partially migratory blue tits (Cyanistes caeruleus) in southern Sweden as a model species. Migrants had higher CORT levels at the time of capture than residents, indicating migratory preparations, adaptation to stressors, higher allostatic load or possibly low social status. Migrants and residents had the same stress response, thus contradicting the migration-modulation hypothesis. We suggest that migrants travelling short distances are more benefited than harmed by retaining the ability to respond to ...
Within-population colour variation is widespread in animals, yet the determinants of variable coloration have been relatively neglected by ecologists. Age-dependent expression of conspicuous coloration is prevalent, particularly in birds. Such patterns can be generated by multiple combinations of demographic heterogeneity or within-individual change; longitudinal analyses are necessary to establish the importance of these processes. Further, although pigment-based colours are composite traits, produced by multiple component mechanisms (e.g. feather microstructure and carotenoid pigmentation), the contributions of these mechanisms to components of age dependence are rarely considered, even though doing so may yield information about the ecological causes for age-dependent coloration. We used a large-scale, longitudinal study of carotenoid-based plumage coloration in great tits (Parus major) to show age dependence of plumage coloration is driven almost exclusively by within-individual effects in the first
Passerines (phylum Chordata, subphylum Vertebrata, superclass Tetrapoda, class Aves, order Passeriformes), sometimes called perching birds, are birds adapted to hold on to a perch tightly, even when they are asleep. Three of their four toes are oriented forward, and the remaining one is oriented backwards. All the toes can move independently of each other, with the back toe being exceptionally strong. And when a passerine lands on a perch, its weight causes the tendons in the leg to tighten and the toes will clamp together tightly, allowing the bird to have a tight grip on the perch ...
While this is the first study that establishes the Great tit as a part-time bat predator, this is (as usual) not really a new discovery. As Estók et al. (2009) note, bats that appear to have been killed by Great tits have been discovered at or around caves before (in Poland and Sweden). Given the remarkable opportunism of this flexible species we should expect it to take advantage of new food sources. Murderous tendencies!. Though mostly feeding on insects and seeds (in the winter, 90% of the northern European Great tit diet consists of plant material*), the Great tit is fairly powerful and formidable for its size, and can use its bill to break into hazelnuts and acorns. Its also an accomplished raider of caches created by other passerines (in particular those of the smaller Marsh tit Poecile palustris and Coal tit Periparus ater**; unlike these species, the Great tit does not [in general] hoard food), and its even been reported to use tools (conifer needles) to winkle insect larvae out ...
Researchers at Oxford University have monitored the behaviour of millions of wild great tits - Parus major - in order to try and reconstruct the 'big picture' of how individual birds are connected.
During egg formation, female birds deposit antibodies against parasites and pathogens they were exposed to before egg laying into the yolk. In captive bird species, it has been shown that these maternal immunoglobulins (maternal yolk IgGs) can protect newly hatched offspring against infection. However, direct evidence for such benefits in wild birds is hitherto lacking. We investigated (1) if nestling Great Tits Parus major originating from eggs with naturally high levels of maternal yolk IgG are less susceptible to a common, nest-based ectoparasite, (2) if maternal yolk IgGs influence nestling development and in particular, their own immune defence, and (3) if there is a negative correlation between levels of maternal yolk IgG in host eggs and the reproductive success of ectoparasitic fleas feeding on the nestlings. Counter to expectations, we found no indication that maternally transferred yolk IgGs have direct beneficial effects on nestling development, nestling immune response or nestling ...
Black-capped ( Poecile atricapillus ) and Carolina ( P. carolinensis ) chickadees hybridize extensively in a long and narrow contact zone, but mechanisms of mate choice remain incompletely understood. I investigated nonbreeding social relationships, which may affect pairing, in southeastern Pennsylvania. During my study, irrupting Black-capped Chickadees joined local hybrid residents, so I also investigated their relationships. Males participated in more social interactions than did females, but there was no difference in average dominance rank. Older birds were not more dominant than younger birds. Known social pairs did not have high association index values during the winter months. Sex or dominance rank did not affect distance moved between breeding season and winter months. Irruption Black-capped Chickadees did not become integrated within local hybrid flocks. This study suggests that flock structure in local flocks maybe less tightly structured and more difficult to study than in regions ...
Whitehead (right) is the only mohouid on North Island, where it occurs patchily and locally in native forest, adjacent gardens, and sometimes scrubland. It is about the size of Great Tit Parus major but the proportions are different, being longer-tailed and bigger-billed. They are usually are found in pairs. Mohouids have previously been included in many different families. Boles (2007) mentions Paridae, Timaliidae, Orthonychidae, Campephagidae, Sylviidae, Maluridae, Pardalotidae, and Acanthizidae. Sibley & Monroe (1990) and Dickinson (2003) put them in the latter family, among Australasian warblers. Boles (2007) included them in a very broad Whistler family [Pachycephalidae]. Heather & Robertson (1996) also put them in Whistlers. Norman et al. (2009) and Jønsson et al. (2011) were the first genetic works to suggest the mohouids were not closely related to any known family. Aggerbeck et al. (2014) found strong support for the Mohouidae as the basal clade in the corvoid assemblage, and all ...
The calls and song between the Carolina chickadee and the Black-capped chickadee differ subtly to an experienced ear: the Carolina chickadees chick-a-dee call is faster and higher pitched than that of the black-capped chickadee, and the Carolina chickadee has a four note fee-bee-fee-bay song, whereas the black-capped omits the high notes. Identification is very difficult even with an excellent view. The most famous call is the familiar chick-a-dee-dee-dee which gave this bird its name and its song is fee-bee-fee-bay. Carolina chickadees are so similar to black-capped chickadees that they themselves have trouble telling their species apart. Because of this they sometimes mate producing hybrids. The most obvious difference between the three chickadees is that the Carolina chickadee sings four-note song, black-capped sing two-note songs, and the hybrids sing three-note songs.[3] ...
Body temperature (Tb) is a valuable parameter when assessing the physiological state of animals, but its widespread measurement is often constrained by methods that are invasive or require frequent recapture of animals. Alternatives based on automated remote sensing of peripheral Tb show promise, but little is known about their strengths and limitations. We measured peripheral Tb in great tits Parus major with subcutaneously implanted passive integrated transponders (PIT tags) and externally attached radio transmitters to determine repeatability of measurements, sensitivity of each method to variation in ambient temperature (Ta) and wind speed, the relationship between methods, and their ability to capture circadian variation in Tb. Repeatability of measurements by radio transmitters was high (> 80%) when readings were taken within 20 min, but reduced to 16% when measures were spaced 3.5 h apart. PIT tag data for the 3.5 h interval were more repeatable (33%) and less variable (cv). Data were ...
The effect of Melatonin (MEL) and p-chlorophenyl-alanine (PCPA), a β-adrenergic antagonist on immune and reproductive status was studied during reproductively active phase of Indian Passeriformes Finch, Lonchura punctulata. MEL treatment to these birds showed significant increase in the immune parameters such as spleen weight, blastogenic response of splenocytes, total leukocyte count and lymphocyte count, whereas PCPA treatment showed significant decrease in all these immune parameters. On the other hand the treatment of MEL and PCPA together to the birds showed an increase in immune parameters as compared with control group of birds. Histological observations of the spleen substantiate the data of spleen weight analysis as MEL treatment to the bird increased the splenocytes density in spleen, whereas PCPA treatment to the bird showed depletion of splenocytes in spleen. The results of the present study suggest immune-stimulatory and anti-gonadal effect of the neuro-hormone MEL in this avian species.

Two recent papers analysing nuclear DNA sequence data shed new light on the origin of perching birds (Passeriformes) and the structure of their radiation. Both papers find that the New Zealand wrens Acanthisitta fall at the base of the passerine radiation, implying an origin of this clade in Gondwana. Additionally, among oscine passerines (songbirds), both papers fail to support a sister group relationship between the largely Australo-Papuan Corvida and the Afro-Eurasian Passerida, as outlined in Sibley and Ahlquists tapestry. Rather, they converge on a phylogeny in which the Passerida is nested within the Corvida, suggesting an origin of songbirds in eastern Gondwana (Australia plus New Guinea). Finally, a Cretaceous origin of passerine birds is supported by the new data, albeit more on grounds of biogeography than of molecular clocks. The new papers solidify a synthesis of paleontological, phylogenetic and molecular data that has been growing over the past decade, and pave the way for a new ...

Arkhon Infaustus est un groupe de black/death metal français (Paris) fondé en 1997 par Dk Deviant et 666 Torturer. Leur musique est caractérisée par la brutalité du death metal dans la voix et linsalubrité du black metal dans le reste des instruments. Arkhon Infaustus est réputé pour évoluer dans un monde sataniste et sado-maso ce qui leur vaut la critique de nombreuses personnes.
Eighty-nine free-living birds of prey and owls were examined and blood samples and radiographs were taken. In addition, 126 specimens of renal tissue were obtained without complications, with a mean postbiopsy haemorrhage time of 67 seconds. On average, the samples were 2.2 mm long, 1.3 mm wide and 1.0 mm deep and they all contained proximal and distal tubuli and from one to 89 glomeruli; 49 of them contained from one to four intralobular veins, and on average each sample contained 10.7 per cent air sac tissue; 113 of the 126 samples could be evaluated histologically.. ...

Cape white-eyes are small passerines that measure up to 12 cm in length and weigh about 9.15 g. These birds have rounded wings with a wingspan of 7 cm. Cape white-eyes plumage is greenish yellow on the upper portions of the body with a gray upper back while the throat is a bright yellow. Their belly is usually a peach color and the most distinguishing feature is the white ring around their eyes. They go through no seasonal plumage color change. These birds feature black, short decurved beaks which aid in gathering nectar. The legs are either gray to brown or pink depending on age. Older birds and fledglings maintain a pinkish shade while first-years have grayish-brown coloration. Cape white-eyes are sexually monomorphic.. Some subspecies exhibit plumage differences, mainly in coloration of breast and belly. (Z. p. virens) and (Z. p. caniviridis) have a greenish-yellow breast and belly while (Z. p. atmorii) and (Z. p. capensis) have a gray coloration. (Z. p. pallidus) and (Z. p. sundevalli) ...
Despite no difference in the time spent foraging terrestrially (and thus exposed to terrestrial predators), drongos gave alarm calls to terrestrial predators more often when following pied babbler groups. This difference may be explained by the benefits received from audience response. Drongos foraging solitarily regularly alarmed at aerial predators providing support for the idea that individuals may use alarm calls as signals to warn approaching predators that they have been detected (Zahavi 1977; Bergstrom & Lachmann 2001). Since solitary drongos primarily forage by hawking aerial prey, terrestrial predators are unlikely to pose a threat to them, and thus there is little benefit in giving an alarm call to this predator type. In contrast, drongos following pied babbler groups benefit from giving alarm calls to terrestrial predators because these predators are a direct threat to their host species (Ridley & Raihani 2007). While drongos in kleptoparasitic mode spent a greater proportion of time ...
As a case study for single-nucleotide polymorphism (SNP) identification in species for which little or no sequence information is available, we investigated several approaches to identifying SNPs in two passerine bird species: pied and collared flycatchers (Ficedula hypoleuca and F. albicollis). All approaches were successful in identifying sequence polymorphism and over 50 candidate SNPs per species were identified from ≈ 9.1 kb of sequence. In addition, 17 sites were identified in which the frequency of alternative bases differed by , 50% between species (termed interspecific SNPs). Interestingly, polymorphism of microsatellite/intron loci in the source species appeared to be a positive predictor of nucleotide diversity in homologous flycatcher sequences. The overall nucleotide diversity of flycatchers was 2.3-2.7 × 10−3, which is ≈ 3-6 times higher than observed in recent studies of human SNPs. Higher nucleotide diversity in the avian genome could be due to the relatively older age of ...

In natural populations, mating between relatives can have important fitness consequences due to the negative effects of reduced heterozygosity. Parental level of inbreeding or heterozygosity has been also found to influence the performance of offspring, via direct and indirect parental effects that are independent of the progeny own level of genetic diversity. In this study, we first analysed the effects of parental heterozygosity and relatedness (i.e. an estimate of offspring genetic diversity) on four traits related to offspring viability in great tits (Parus major) using 15 microsatellite markers. Second, we tested whether significant heterozygosity-fitness correlations (HFCs) were due to local (i.e. linkage to genes influencing fitness) and/or general (genome-wide heterozygosity) effects. We found a significant negative relationship between parental genetic relatedness and hatching success, and maternal heterozygosity was positively associated with offspring body size. The ...

1. Persistent pesticide residues remain a significant environmental pollutant, reducing breeding success of predatory birds even where such pesticides have been banned for many years. The ability to detect such residues inexpensively without destructive sampling would be a valuable tool for ecotoxicological monitoring. We suggest that assaying eggshell colour might provide such a tool. 2. Recent studies have revealed two mechanisms affecting eggshell pigmentation in, and believed to be specific to, passerine birds. In the great tit Parus major, reddish protoporphyrin speckles on their otherwise white eggs coincide precisely with thin shell and are related to calcium shortage. In the pied flycatcher Ficedula hypoleuca, the intensity of the eggshells blue-green ground-colour (pigment biliverdin) is related to the females health (immunocompetence) at laying. We studied the effect of the insecticide DDT (notorious for reducing eggshell thickness in raptors by blocking calcium availability to the shell
The Bronzed Cowbird is a brood parasite that ranges from the U.S. - Mexico border southward to northern Colombia, occurring in all Central American countries in between. Bronzed Cowbirds are slightly larger than the better known and related Brown-headed Cowbird (Molothrus ater); the average host of the Bronzed Cowbird is also larger than the average host of the Brown-headed Cowbird. Many aspects of the Bronzed Cowbirds breeding biology are probably similar to those of the Brown-headed Cowbird, although the former may be more specialized in its host selection.. Human settlement of the New World has led to habitat changes favorable for Molothrus cowbirds; range expansion by Bronzed Cowbirds, in particular, was first noted early this century and a more dynamic northward expansion began in the 1950s in the United States. As the overlap in distribution between Bronzed and Brown-headed Cowbirds increases, the resulting dynamics of community interactions between brood parasites and hosts will ...
Combinations of microstructural and pigmentary components of barbs create the colour displays of feathers. It follows that evolutionary changes in colour displays must reflect changes in the underlying production mechanisms, but rarely have the mechanisms of feather colour evolution been studied. Among bluebirds in the genus Sialia, male rump colour varies among species from dark blue to light blue while breast colour varies from blue to rusty. We use spectrometry, transmission electron microscopy and Fourier analysis to identify the morphology responsible for these divergent colour displays. The morphology of blue rump barbs is similar among the three species, with an outer keratin cortex layer surrounding a medullary spongy layer and a basal row of melanin granules. A spongy layer is also present in blue breast barbs of mountain bluebirds Sialia currucoides and in rusty breast barbs of western Sialia mexicana and eastern bluebirds Sialia sialis. In blue barbs melanin is basal to the spongy ...
Metaller är grundämnen som inte kan bildas eller förstöras av människan. De förekommer i mineraler i berggrunden och finns överallt på jorden. Människans användning av metaller har dock medfört att de återfinns i högre halter i miljön än de annars skulle gjort.. Trots att metallerna kan spridas och transporteras långa sträckor med luftmassorna, är det främst kring källorna, såsom metallindustrier, man kan hitta metaller i tillräckligt höga halter för att orsaka skada på växter och djur. I denna avhandling presenteras undersökningar av hur svartvit flugsnappare (Ficedula hypoleuca) påverkas kring två metallindustrier i norra Sverige. Det ena är en numera nedlagd blygruva med anrikningsverk i Laisvall, där vi studerade populationer av svartvit flugsnappare före och efter att industrin stängdes.

Passerines respond to high temperature by substantially increasing their body temperature (Tb) in an attempt to save water initially. However, most year-round passerines are able to inhabit areas with drastic thermal fluctuations with their ability to be physiologically plastic when faced with increases in temperature. We will collect individuals from 5 different avian species: Sturnus vulgaris (European starling), Passer domesticus (House Sparrows), Poecile atricapillus (black- capped chickadee), Junco hyemalis (dark eyed juncos), Columba livia (Rock pigeon). The species included in this experiment have been chosen because they abundantly available year-round in central New York, and because they vary in body sizes from 10 g to 300 g, allowing this study to further incorporate body mass scaling as a component. Birds will be collected in the field using mist-nets, placed in cages and transported back to Colgate University. Birds will be acclimated to a control (ambient temperature) and heat ...
There is a question as to why the majority of the hosts of brood parasites care for the nestlings of their parasites. Not only do these brood parasites usually differ significantly in size and appearance, but it is also highly probable that they reduce the reproductive success of their hosts. The mafia hypothesis evolved through studies in an attempt to answer this question. This hypothesis revolves around host manipulations induced by behaviors of the brood parasite. Upon the detection and rejection of a brood parasites egg, the hosts nest is depredated upon, its nest destroyed and nestlings injured or killed. This threatening response indirectly enhances selective pressures favoring aggressive parasite behavior that may result in positive feedback between mafia-like parasites and compliant host behaviors.[13]. There are two avian species that have been speculated to portray this mafia-like behavior: the brown-headed cowbird of North America, Molothrus ater, and the great spotted cuckoo of ...

Variation in the reactivity of the endocrine stress axis is thought to underlie aspects of persistent individual differences in behavior (i.e. animal personality). Previous studies, however, have focused largely on estimating baseline or peak levels of glucocorticoids (CORT), often in captive animals. In contrast, the temporal dynamics of the HPA axis-how quickly it turns on and off, for example-may better indicate how an individual copes with stressors. Moreover, these HPA components might be correlated, thereby representing endocrine suites. Using wild-caught great tits (Parus major) we tested birds for exploratory behavior using a standardized novel environment assay that serves as a validated proxy for personality. We then re-captured a subset of these birds (n=85) and characterized four components of HPA physiology: baseline, endogenous stress response, a dexamethasone (DEX) challenge to estimate the strength of negative feedback, and an adrenocorticotropic hormone (ACTH) challenge to ...

John James Audubon named this bird while he was in South Carolina. The curious, intelligent Carolina Chickadee looks very much like a Black-capped Chickadee, with a black cap, black bib, gray wings and back, and whitish underside. Carolina and Black-capped chickadees hybridize in the area where their ranges overlap, but the two species probably diverged more than 2.5 million years ago.

This led the team to conclude that note sharing is probably not the main mechanism by which Western Bluebirds recognize their relatives. It may be a piece of the puzzle, but is unlikely to be sufficient for kin recognition, because unrelated neighbors share notes as well, and related males did not share notes if they didnt live next to each other. There may be some other cue that allows bluebirds to more reliably distinguish kin from non-kin. Alternatively, there may not be any one blanket signature that is common to all members of a family. Instead, Western Bluebirds may actually know the song of each male in their area and recognize them as individuals. If this is the case, it still begs the question of how the bluebirds learn which individuals are related to them. This remains a mystery waiting to be unraveled.. Reference: Akçay, Ç., Hambury, K.

Very similar to the Black-capped Chickadee, this bird replaces it in the southeastern states. Living in milder climates, it has been reported to be less of a visitor to bird feeders, but it does come into suburban yards for sunflower seeds. Where the ranges of Black-capped and Carolina chickadees come together, they often interbreed. In these contact zones, they also can learn to imitate each others songs -- causing great confusion for birdwatchers.

BaseballStL) -- It all really began as a way to, as Mike Matheny put it, waken up the starters. The Cardinals were not a good bunting team last year. And, really, thats being nice. They were borderline atrocious.. So, Matheny had a bunting competition. Pitchers. Position players. Everyone was invited to participate. After several preliminary rounds, it was down to two.. And today, Pete Kozma (representing the position players) and Michael Blazek (representing the pitchers) took part in the championship. The entire team congregated on one of the practice fields to watch - once and for all - who the bunting champion turned out to be.. Now, Kozma ended up winning. Is that a big deal? Is that something thats going to change the fortunes of this franchise?. Um. No.. But what Mathenys doing is making bunting a fun game to get everyone to care about it more. If theres a gigantic competition with the whole team watching, clearly they wont want to embarrass themselves. Theyll subconsciously, or ...

They are robust, seed-eating birds with strong bills. The familys smallest member is the 12-cm (4.7-in), 11.5-g (0.40-oz) orange-breasted bunting. They are typically associated with open woodland. The sexes usually have distinctive appearances. The northern cardinal type species was named by colonists for the males red crest, reminiscent of a Catholic cardinals biretta.[1]. The North American buntings are known as such to distinguish them from buntings of the Old World family Emberizidae. The name cardinal-grosbeak can also apply to the cardinalid family as a whole. Most species are rated by the IUCN as being of least concern, though some are near threatened.[2]. ...
For both pied flycatchers and blackcaps, our data obtained under the stationary sky can best be explained by Hypothesis 3. Birds use the stars as a compass only, and this compass most likely is based on geometrical recognition of star patterns learned during ontogeny, and therefore seems independent of celestial rotation and time later in life.. The pied flycatchers clearly oriented in more or less the normal migratory direction all night, even though the stars were stationary. No clear change in direction towards the end of the night, as would be expected if they had been performing true star navigation, was observed (Hypothesis 1a-c). In other words, they did not seem to perceive any longitudinal displacement during the night. Also, there was no gradual change in orientation consistent with a time-compensated star compass (Hypothesis 2).. The data on the blackcaps are less clearcut, probably because of the relatively low sample size (N=7). The data appear to show a turn towards the west in the ...
Monday of this week, I was pleasantly surprised when I came home and found a male painted bunting on my bird feeder. After a few minutes of feeding, he flew away. I figured he might well be a migratory bird just passing through. I did not see one again until this morning when there was not one, but two male painted buntings on my feeder simultaneously. They were flitting out to the woods behind my fence and back for a good twenty minutes. Ive not seen a female so far, but I expect that I will. The colors are blue, green, and red. They also have remarkable ruby-red eyes.They are indigenous to the area, but its the first time Ive seen them in the 15.5 years Ive been here. Anyone else? Meanwhile, activity is picking up over at the occupied blue bird house on the back fence. Im guessing eggs have now hatched.

Birders might say that this blackbird is rusty because it spends so much time in the water. In migration and winter it is usually in swampy places, wading in very shallow water at the edges of wooded streams. In summer it retires to northern spruce bogs; no other blackbird has such a northerly breeding distribution. The name Rusty applies to the colors of fall birds, but it could also describe the rusty-hinge sound of the creaking song.

Sunbirds range in body length from 4-9 in (9-22 cm). The wings are short and rounded, and the tail is quite long in some species. They have a long, pointed, down-curved beak, which in some species exceeds the length of the head. The tongue is long, tubular for about two-thirds of its length, and its tip is split. The unusual bill and tongue of sunbirds are adaptations to feeding on the nectar of flowers. There are fine serrations near the tip of the beak, which are thought to be an adaptation to gripping insects.. Male sunbirds are brightly and garishly colored in bold patterns of green, blue, purple, red, black, or white. Many of these superb hues are due to a iridescence of the feathers, which is a prism-like, physical phenomenon, rather than the color of pigments. Female sunbirds are more subdued in their coloration, and are not iridescent. The sunbirds and hummingbirds (family Trochilidae) are not related, but they are similar in aspects of their iridescent coloration, and their ...
