Obliterative endophlebitis in mute swans (Cygnus olor) caused by Trichobilharzia sp. (Digenea: Schistosomatidae) infection. (1/90)

Schistosome infections in mammals cause chronic proliferative vascular lesions associated with the presence of adult parasites in the lumen of mesenteric and portal veins. In birds, however, this has never been reported. In this study, we found obliterative endophlebitis associated with the presence of adult schistosomes (Trichobilharzia sp., probably Trichobilharzia filiformis) as the main pathologic finding in five of eight mute swans (Cygnus olor). On histologic examination, the intestinal and portal veins of these swans showed moderate to severe, diffuse, hyperplastic endophlebitis, characterized by myointimal hyperplasia, often with obliteration of the vascular lumen. In addition, moderate to severe lymphocytic and granulocytic enteritis occurred in all eight swans associated with the presence of schistosome eggs in the intestinal mucosa. Other findings included hepatic and splenic hemosiderosis and high hepatic copper levels. The vascular lesions associated with Trichobilharzia sp. infection may have contributed to the emaciation and death of those mute swans by obstruction of venous return in the intestinal and portal veins.  (+info)

Identification and characterization of avihepadnaviruses isolated from exotic anseriformes maintained in captivity. (2/90)

Five new hepadnaviruses were cloned from exotic ducks and geese, including the Chiloe wigeon, mandarin duck, puna teal, Orinoco sheldgoose, and ashy-headed sheldgoose. Sequence comparisons revealed that all but the mandarin duck viruses were closely related to existing isolates of duck hepatitis B virus (DHBV), while mandarin duck virus clones were closely related to Ross goose hepatitis B virus. Nonetheless, the S protein, core protein, and functional domains of the Pol protein were highly conserved in all of the new isolates. The Chiloe wigeon and puna teal hepatitis B viruses, the two new isolates most closely related to DHBV, also lacked an AUG start codon at the beginning of their X open reading frame (ORF). But as previously reported for the heron, Ross goose, and stork hepatitis B viruses, an AUG codon was found near the beginning of the X ORF of the mandarin duck, Orinoco, and ashy-headed sheldgoose viruses. In all of the new isolates, the X ORF ended with a stop codon at the same position. All of the cloned viruses replicated when transfected into the LMH line of chicken hepatoma cells. Significant differences between the new isolates and between these and previously reported isolates were detected in the pre-S domain of the viral envelope protein, which is believed to determine viral host range. Despite this, all of the new isolates were infectious for primary cultures of Pekin duck hepatocytes, and infectivity in young Pekin ducks was demonstrated for all but the ashy-headed sheldgoose isolate.  (+info)

Surveillance of amyloidosis and other diseases at necropsy in captive trumpeter swans (Cygnus buccinator). (3/90)

The purpose of this study was to characterize the incidence and diagnostic features of amyloidosis and other diseases found at necropsy in captive trumpeter swans (Cygnus buccinator). A search of Iowa State University's Department of Veterinary Pathology and Veterinary Diagnostic Laboratory databases yielded 31 trumpeter swan (C. buccinator) necropsy cases from captive swans in protected habitats. Eleven of the 31 birds had amyloid deposition most commonly in the spleen (8 of 11), liver (7 of 11), and kidney (6 of 11) and less often in the pancreas (2 of 11) and adrenal gland (2 of 11). Amyloid deposition effaced normal tissue with adjacent necrosis and hemorrhage in severe cases. Amyloidosis was most often diagnosed in February and March. Other disease diagnoses in the trumpeter swans included aspergillosis (5 of 31, 16%); bacterial infection (5 of 31, 16%); lead toxicosis (3 of 31, 10%); gout (2 of 31, 6%); parasitic infection (2 of 31, 6%); vitamin E deficiency (1 of 31, 3%); trauma (1 of 31, 3%); and ventricular foreign body (1 of 31, 3%). Histopathologic, toxicologic, and microbiologic analyses did not define an etiologic diagnosis in the deaths of 9 trumpeter swans. In these cases, necropsy lesions included emaciation (5 of 9), enteritis (1 of 9), pulmonary hemorrhage (1 of 9), and no lesions (3 of 9). The number of trumpeter swan case submissions was greatest in January and February. This study provides a reference for veterinary diagnosticians concerning incidence and diagnostic features of amyloidosis and other diseases in captive trumpeter swans of the midwestern United States.  (+info)

Cost of reproduction in a long-lived bird: incubation effort reduces immune function and future reproduction. (4/90)

Life-history theory predicts that increased current reproductive effort should lead to a fitness cost. This cost of reproduction may be observed as reduced survival or future reproduction, and may be caused by temporal suppression of immune function in stressed or hard-working individuals. In birds, consideration of the costs of incubating eggs has largely been neglected in favour of the costs of brood rearing. We manipulated incubation demand in two breeding seasons (2000 and 2001) in female common eiders (Somateria mollissima) by creating clutches of three and six eggs (natural range 3-6 eggs). The common eider is a long-lived sea-duck where females do not eat during the incubation period. Mass loss increased and immune function (lymphocyte levels and specific antibody response to the non-pathogenic antigens diphtheria and tetanus toxoid) was reduced in females incubating large clutches. The increased incubation effort among females assigned to large incubation demand did not lead to adverse effects on current reproduction or return rate in the next breeding season. However, large incubation demand resulted in long-term fitness costs through reduced fecundity the year after manipulation. Our data show that in eiders, a long-lived species, the cost of high incubation demand is paid in the currency of reduced future fecundity, possibly mediated by reduced immune function.  (+info)

Age-dependent genetic variance in a life-history trait in the mute swan. (5/90)

Genetic variance in characters under natural selection in natural populations determines the way those populations respond to that selection. Whether populations show temporal and/or spatial constancy in patterns of genetic variance and covariance is regularly considered, as this will determine whether selection responses are constant over space and time. Much less often considered is whether characters show differing amounts of genetic variance over the life-history of individuals. Such age-specific variation, if present, has important potential consequences for the force of natural selection and for understanding the causes of variation in quantitative characters. Using data from a long-term study of the mute swan Cygnus olor, we report the partitioning of phenotypic variance in timing of breeding (subject to strong natural selection) into component parts over 12 different age classes. We show that the additive genetic variance and heritability of this trait are strongly age-dependent, with higher additive genetic variance present in young and, particularly, old birds, but little evidence of any genetic variance for birds of intermediate ages. These results demonstrate that age can have a very important influence on the components of variation of characters in natural populations, and consequently that separate age classes cannot be assumed to be equivalent, either with respect to their evolutionary potential or response.  (+info)

Quantitative genetics of age at reproduction in wild swans: support for antagonistic pleiotropy models of senescence. (6/90)

Why do individuals stop reproducing after a certain age, and how is this age determined? The antagonistic pleiotropy theory for the evolution of senescence predicts that increased early-life performance should be accompanied by earlier (or faster) senescence. Hence, an individual that has started to breed early should also lose its reproductive capacities early. We investigate here the relationship between age at first reproduction (AFR) and age at last reproduction (ALR) in a free-ranging mute swan (Cygnus olor) population monitored for 36 years. Using multivariate analyses on the longitudinal data, we show that both traits are strongly selected in opposite directions. Analysis of the phenotypic covariance between these characters shows that individuals vary in their inherent quality, such that some individuals have earlier AFR and later ALR than expected. Quantitative genetic pedigree analyses show that both traits possess additive genetic variance but also that AFR and ALR are positively genetically correlated. Hence, although both traits display heritable variation and are under opposing directional selection, their evolution is constrained by a strong evolutionary tradeoff. These results are consistent with the theory that increased early-life performance comes with faster senescence because of genetic tradeoffs.  (+info)

Identification of a novel bile acid in swans, tree ducks, and geese: 3alpha,7alpha,15alpha-trihydroxy-5beta-cholan-24-oic acid. (7/90)

By HPLC, a taurine-conjugated bile acid with a retention time different from that of taurocholate was found to be present in the bile of the black-necked swan, Cygnus melanocoryphus. The bile acid was isolated and its structure, established by (1)H and (13)C NMR and mass spectrometry, was that of the taurine N-acyl amidate of 3alpha,7alpha,15alpha-trihydroxy-5beta-cholan-24-oic acid. The compound was shown to have chromatographic and spectroscopic properties that were identical to those of the taurine conjugate of authentic 3alpha,7alpha,15alpha-trihydroxy-5beta-cholan-24-oic acid, previously synthesized by us from ursodeoxycholic acid. By HPLC, the taurine conjugate of 3alpha,7alpha,15alpha-trihydroxy-5beta-cholan-24-oic acid was found to be present in 6 of 6 species in the subfamily Dendrocygninae (tree ducks) and in 10 of 13 species in the subfamily Anserinae (swans and geese) but not in other subfamilies in the Anatidae family. It was also not present in species from the other two families of the order Anseriformes. 3alpha,7alpha,15alpha-Trihydroxy-5beta-cholan-24-oic acid is a new primary bile acid that is present in the biliary bile acids of swans, tree ducks, and geese and may be termed 15alpha-hydroxy-chenodeoxycholic acid.  (+info)

Regulation of stroke pattern and swim speed across a range of current velocities: diving by common eiders wintering in polynyas in the Canadian Arctic. (8/90)

Swim speed during diving has important energetic consequences. Not only do costs increase as drag rises non-linearly with increasing speed, but speed also affects travel time to foraging patches and therefore time and energy budgets over the entire dive cycle. However, diving behaviour has rarely been considered in relation to current velocity. Strong tidal currents around the Belcher Islands, Nunavut, Canada, produce polynyas, persistent areas of open water in the sea ice which are important habitats for wildlife wintering in Hudson Bay. Some populations of common eiders Somateria mollissima sedentaria remain in polynyas through the winter where they dive to forage on benthic invertebrates. Strong tidal currents keep polynyas from freezing, but current velocity can exceed 1.5 m s(-1) and could influence time and energy costs of diving and foraging. Polynyas therefore provide naturally occurring flume tanks allowing investigation of diving strategies of free ranging birds in relation to current velocity. We used a custom designed sub-sea ice camera to non-invasively investigate over 150 dives to a depth of 11.3 m by a population of approximately 100 common eiders at Ulutsatuq polynya during February and March of 2002 and 2003. Current speed during recorded dives ranged from 0 to 1 m s(-1). As currents increased, vertical descent speed of eiders decreased, while descent duration and the number of wing strokes and foot strokes during descent to the bottom increased. However, nearly simultaneous strokes of wings and feet, and swim speed relative to the moving water, were maintained within a narrow range (2.28+/-0.23 Hz; 1.25+/-0.14 m s(-1), respectively). This close regulation of swim speed over a range in current speed of 1.0 m s(-1) might correspond to efficient muscle contraction rates, and probably reduces work rates by avoiding rapidly increasing drag at greater speeds; however, it also increases travel time to benthic foraging patches. Despite regulation of average swim speed, high instantaneous speeds during oscillatory stroking can increase dive costs due to drag. While most diving birds have been considered either foot or wing propelled, eider ducks used both wing and foot propulsion during descent. Our observations indicate that the power phase of foot strokes coincides with the transition between upstroke and downstroke of the wings, when drag is greatest. Coordinated timing between foot and wing propulsion could therefore serve to maintain a steadier speed during descent and decrease the costs of diving. Despite tight regulation of stroke and swim speed patterns, descent duration and total number of foot and wing strokes during descent increase non-linearly with increasing current velocity, suggesting an increase in energetic costs of diving.  (+info)

The trumpeter swan is the largest extant species of waterfowl. Adults usually measure 138-165 cm (4 ft 6 in-5 ft 5 in) long, though large males can exceed 180 cm (5 ft 11 in) in total length.[2][6][7][8] The weight of adult birds is typically 7-13.6 kg (15-30 lb). Possibly due to seasonal variation based on food access and variability due to age, average weights in males have been reported to range from 10.9 to 12.7 kg (24 to 28 lb) and from 9.4 to 10.3 kg (21 to 23 lb) in females.[2][9][10][11] It is one of the heaviest living birds or animals capable of flight. Alongside the mute swan (Cygnus olor), Dalmatian pelican (Pelecanus crispus), kori bustard (Ardeotis kori), and Andean condor (Vultur gryphus), it is one of a handful to weigh in excess of 10 kg (22 lb) between the sexes, and one survey of wintering trumpeters found it averaged second only to the condor in mean mass.[12][13] The trumpeter swans wingspan ranges from 185 to 250 cm (6 ft 1 in to 8 ft 2 in), with the wing chord measuring ...

We collected carcasses of 52 common eider Somateria mollissima adults and ducklings and blood samples from 11 nesting eider hens in the Gulf of Finland near Helsinki in 1994, 1995 and 1996. Samples of liver tissue were analysed for arsenic, cadmium, chromium, copper, iron, lead, magnesium, manganese, mercury, molybdenum, selenium and zinc. Blood was analysed for lead, mercury and selenium. Most of the 21 adults examined at necropsy were emaciated with empty gizzards, and no ingested shotgun pellets or other metal were found in any of the birds. Three adult females had a combination of lesions and tissue lead residues characteristic of lead poisoning. Two of these birds had acid-fast intranuclear inclusion bodies in renal epithelial cells and high concentrations of lead (73.4 and 73.3 ppm; all liver residues reported on dry weight basis) in their livers. The third was emaciated with a liver lead concentration of 47.9 ppm. An...

High-throughput or Next-Generation sequencing (NGS) has proven to be a time-efficient and cost-effective technique for the sequencing of whole-genomes. Despite its benefits, high-throughput sequencing is remaining a relatively nascent technique for phylogenetic analyses (McCormack 2013). We performed sequence assembly and analysis of genomic reads from a wild Tundra Swan (C. columbianus) and a wild Trumpeter Swan (Cygnus buccinator). The reads were assembled into Contigs that were later run through a custom Perl script designed to extract the differences between sequences. We also performed further analysis of the genetic relatedness between swan species using sequences of nuclear gene encoding the chromo-helicase-DNA binding domain (CHD) and associated introns that involved alignments and phylogenetic tree construction. Additionally, polymorphisms in the mitochondrial control region (D-loop) of Trumpeters, Tundra Swans, and hybrids were used for phylogenetic trees analysis. The phylogenetic ...
In April and May 2008, whooper swans (Cygnus cygnus) were found dead in Hokkaido in Japan. In this study, an adult whooper swan found dead beside Lake Saroma was pathologically examined and the identified H5N1 influenza virus isolates were genetically and antigenically analyzed. Pathological findings indicate that the swan died of severe congestive edema in the lungs. Phylogenetic analysis of the HA genes of the isolates revealed that they are the progeny viruses of isolates from poultry and wild birds in China, Russia, Korea, and Hong Kong. Antigenic analyses indicated that the viruses are distinguished from the H5N1 viruses isolated from wild birds and poultry before 2007. The chickens vaccinated with A/duck/Hokkaido/Vac-1/2004 (H5N1) survived for 14 days after challenge with A/whooper swan/Hokkaido/1/2008 (H5N1), although a small amount of the challenge virus was recovered from the tissues of the birds. These findings indicate that H5N1 highly pathogenic avian influenza viruses are circulating in

Pochard, (tribe Aythyini), any of the 14 to 16 species of diving ducks of the tribe Aythyini (family Anatidae, order Anseriformes), often called bay ducks. Pochards are round-bodied, big-headed, rather silent birds of deep water; they dive well, with closed wings, to feed chiefly on aquatic plants.
Hands were placed on the backs of the birds to restrain them and, in a well-practiced maneuver, slipped around both sides to grasp leathery black legs. The feathery bundles were then hoisted into canoes and kayaks for a trip to a shoreline processing station. Once captured, the birds sat stoically as their long, straight necks periscoped between the knees of the paddlers. Its a privilege to get this close to such magnificent birds, said volunteer Anne Lacey, who also works at the International Crane Foundation in Baraboo. Just 25 years ago, it would have been rare to see - and unthinkable to capture - a trumpeter swan here. Hunting and habitat loss wiped the birds out of the state in the late 1800s. The swans resonant, sonorous call - the source of its name - was absent from Wisconsin for more than 100 years when the DNR began its Trumpeter Swan Recovery Program in 1987, according to state wildlife officials.

Mute swans pair for life and they mate and begin buiding a nest in March and April. Pair bonding takes place from the age of two although swans are not generally mature until three years old and may breed at this age if there is a territory available. The nest is built on the ground, near to water, in an undisturbed place.. The cob collects reeds and sticks, bringing them to the female so she can arrange them. The nest is often a very big platform-like structure, and may be the pairs old nest which has been rebuilt and used year after year. Although the cob and pen look very similar at first glance, they can be told apart by looking at their beaks. In the spring and summer the cobs bill is a brighter colour than the pens, and the black knob is more bulbous. The cob is never far from his mate on the nest, keeping an eye out for intruders. If a potential predator gets too close, he will hiss at them (mute swans are quiet birds on the whole, but are not really mute!) and if necessary will charge ...

The Milky Way and other galaxies in the universe harbor many young star clusters and associations that each contain hundreds to thousands of hot, massive, young stars known as O and B stars. The star cluster Cygnus OB2 contains more than 60 O-type stars and about a thousand B-type stars. At a relatively nearby distance to Earth of about 5,000 light years, Cygnus OB2 is the closest massive cluster. Deep observations with NASAs Chandra X-ray Observatory of Cygnus OB2 have been used to detect the X-ray emission from the hot outer atmospheres, or coronas, of young stars in the cluster and to probe how these great star factories form and evolve. About 1,700 X-ray sources were detected, including about 1,450 thought to be stars in the cluster. In this image, X-rays from Chandra (blue) have been combined with infrared data from NASAs Spitzer Space Telescope (red) and optical data from the Isaac Newton Telescope (orange).

The white cygnet illustrates the fact that Mute Swans (Cygnus olor) have a colour form called immutabilis, or unchanging, and also known as Polish swan. The mutation is sex-linked and recessive, and occurs in a gene located in the Z sex chromosome. Unlike most mammals, female birds have two different sex chromosomes (ZW), while males have two of the same kind (ZZ). If the female has the mutation, she will be white as a cygnet and will moult into an adult white plumage directly. A male needs to have two mutated forms of the gene to be a Polish swan. Immutabilis adults are hard to tell apart when they are in the water, as the only trait that is different is the colour of the feet, which is paler. The immutabilis form is rarer in populations than the normal form, and it is more common in female swans ...

AGILE is detecting enhanced gamma-ray emission from a source positionally consistent with the microquasar Cygnus X-3. Integrating during the period 2011-05-28 07:58:37 UT to 2011-05-29 06:02:51 UT (MJD=55709.33-55710.25) the AGILE-GRID detected gamma-ray emission above 100 MeV from a source at Galactic coordinates (l, b) = (79.8, 0.3) +/- 0.8 (stat.) +/- 0.1 (syst.) deg, and flux F > 300 x 10^-8 photons/cm^2/s above 100 MeV (1-day multi-source-analysis significance in spinning mode ~4 sigma). The multi-source likelihood analysis was carried out taking into account the gamma-ray sources in the field including the nearby pulsars (PSR J2021+3651, PSR J2021+4026, PSR J2032+4127). We notice that the hard X-ray lightcurve of Cygnus X-3 as monitored by the BAT/Swift instrument (public data available at http:///heasarc.gsfc.nasa.gov/docs/swift/results/transients/CygX-3 ) shows an overall decreasing trend starting on MJD ~ 55680. This trend of decreasing hard X-ray emission in conjunction with gamma-ray ...

Each year REGI receives many Trumpeter Swans suffering from lead poisoning. Lead poisoning is a human-caused problem. Lead is accessed by swans when they forage on the bottom of ponds, streams or lakes. Our lakes throughout the country have been used for fishing and hunting of waterfowl for over a hundred years. Recently, the use of lead shot has been made illegal for waterfowl hunting in many states. It is, however, still available for use in fishing and other types of hunting. Unfortunately, lead is pervasive in the environment. It does not decompose. It will be at the bottom of bodies of water forever. Wildlife is particularly at risk to contacting the lead shot and sinkers in years when water levels are low. Lead is highly toxic. That is why we no longer have lead in the paint we use in our homes and unleaded gas is used in our cars. The fact is that a piece of lead the size of a grain of sand can poison a human child. You can imagine what a bit of lead shot can do to wildlife species much ...

The aim of this report is to present data on the trends in population numbers and other vital statistics for inland colonial waterbirds and marsh birds in Canadas 16 terrestrial ecozones+. The data were solicited from members of the Inland Colonial Waterbird and Marsh Bird Chapter of the Canadian Waterbird Technical Committee and other waterbird biologists from across the country. There were surprisingly few long-term datasets identified, particularly for some ecozones+. Some ecozones+ had no data (Taiga Cordillera, Taiga Shield, and Hudson Plains), some had historical data but no current data (Boreal Cordillera, Western Interior Basin, Montane Cordillera, and Prairies), some had data awaiting analysis, and some had recent but no historical data. Nine ecozones+ had one or more dataset of five or more years that was used to give preliminary data; some had much more data than others.

The trees are in their autumn beauty, The woodland paths are dry, Under the October twilight the water Mirrors a still sky; Upon the brimming water among the stones Are nine and fifty swans. The nineteenth Autumn has come upon me Since I first made my count; I saw, before I had well finished, All suddenly mount And scatter wheeling in great broken rings Upon their clamorous wings. I have looked upon those brilliant creatures, And now my heart is sore. Alls changed since I, hearing at twilight, The first time on this shore, The bell-beat of their wings above my head, Trod with a lighter tread. Unwearied still, lover by lover, They paddle in the cold, Companionable streams or climb the air; Their hearts have not grown old; Passion or conquest, wander where they will, Attend upon them still. But now they drift on the still water Mysterious, beautiful; Among what rushes will they build, By what lakes edge or pool Delight mens eyes, when I awake some day To find they have flown away ...

ezcol_1half]. Holy Terror is one of 5 tracks to be featured on the upcoming Mutes EP entitled Starvation Age, which shall be released on June 29th through One Note Forever records.. The midland-based, genre-spanning quartet (having evolved from the solo ambient project of frontman James) self-recorded the EP in a Leeds basement on analog equipment last year, the forthcoming release chews up the more ambient, restrained aspects of Mutes solo releases and spits them out in a far noisier, ragged and yet considered form.. Holy Terror, the first song to be taken from the EP, has been recently premiered on the405. Encapsulating the finer points of Mutes sonic arsenal, the recently released track at first hammers away with razor-sharp guitars, droning vocals and walls of feedback. But as the urgency of the initial assault gives way to soothing ambience and docile bass lines, it becomes clear that Mutes are not disposed to monotony.. [/ezcol_1half]. [ezcol_1half_end]. ...
I thought a lot about the studio while I was in China. During the seminar, we spent a lot of time sitting in classrooms listening to artist presentations, in addition to lectures about the state of religion in China. We visited historic sites, attended church, and moved through various points of interest in each city. Before departing for China, our team had been given a list of books to read. This gave us an opportunity to become more familiar with Chinese culture prior to arriving in Beijing. One book that especially impressed me was Wild Swans by Jung Chang. It told the story of three Chinese women who had lived through, or in close proximity to, Chinas Cultural Revolution. While this book is currently banned in China, I found myself viewing everything through the lens of its story. Wild Swans made me aware of the psychological weight that can be embedded in a place. I found myself questioning what I saw while I was there, while also recognizing that I was contending with my own projection. ...
Return to my illustration of a wetland owned as private property. The wetland is the owners. It is not the governments wetland. If government says the owner cannot fill the wetland because it is habitat for migratory waterfowl, then we should ask if this regulated land use harms the person or property of others. If it does, then government is not taking the persons property. If it does not, government is taking the persons wetland for its own use. No one else owns the habitat in this wetland but the individual owner. Therefore, filling the wetland cannot harm to the property of others. Perhaps the government will say that filling the wetland harms migratory waterfowl since there will be less habitat and hence a smaller population of waterfowl than would otherwise be the case. I think this makes lots of sense. But, who owns the waterfowl? No other person owns the waterfowl. Perhaps we should say that government owns the waterfowl. I think this makes lots of sense as well. Filling the wetland ...

Blood samples from 105 northern pintails (Anas acuta) captured on Hokkaido, Japan were tested for antibodies to avian influenza virus (AIV), Japanese encephalitis virus (JEV), and West Nile virus (WNV) to assess possible involvement of this species in the spread of economically important and potentially zoonotic pathogens. Antibodies to AIV were detected in 64 of 105 samples (61%). Of the 64 positives, 95% and 81% inhibited agglutination of two different H5 AIV antigens (H5N1 and H5N9), respectively. Antibodies to JEV and WNV were detected in five (5%) and none of the samples, respectively. Results provide evidence for prior exposure of migrating northern pintails to H5 AIV which could have implications for viral shedding and disease occurrence. Results also provide evidence for limited involvement of this species in the transmission and spread of flaviviruses during spring migration ...
I have to confess that my whole notion of New Jersey has been the opening scenes of the Sopranos. The words New Jersey have conjured the worst stereotypes of guys named Guido and gum cracking dames with whiny voices and bad red hair. Both of these cartoon characters wear gobs of hideous, big, cheap jewelry. So far, I havent met these people, though they may be lurking in any of the multitude of shopping malls around here. Until yesterday, it had seemed like New Jersey was endless parking lots, malls, concrete and cars. Though I had not met up with any hit men or hookers, New Jersey wasnt redeeming itself to me. But yesterday, David and I went south along the Garden State Parkway to Oceanville to the Edwin B. Forsythe National Wildlife Refuge (Brigantine Division). There, I saw one of the most beautiful things Ive ever seen, these Mute Swans. Birders refer to this Atlantic County wildlife refuge as simply Brigantine, though its not actually in the town of Brigantine. It is an amazingly ...

April 20, 2012 , 4 minute read Morehouse Parish, Louisiana - The U.S. Fish and Wildlife Service (Service) and The Conservation Fund announced today the completion of a multi-year project to add nearly 4,000 acres of mixed farmland and timberland to Upper Ouachita National Wildlife Refuge (NWR) in northeastern Louisiana. This action secures the largest remaining inholding for the Refuge, enabling more effective management of the area for wildlife habitat and public recreation. Located along the Ouachita River at the Louisiana-Arkansas border, the Upper Ouachita NWR provides a seasonal haven for tens of thousands of migratory ducks and geese, including mallards, pintails, wood ducks and snow geese, which visit the refuge every year for resting, foraging and breeding.

Monitoring colonial waterbirds is essential to detect and to provide insights about changes in waterbird distribution and abundance. For colonial waterbirds, major population fluctuations often go undetected because surveys are not conducted regularly, inventory methods are inconsistent, or estimates have unknown reliability. The waterbird colony at Chase Lake National Wildlife Refuge in North Dakota is one of the largest nesting colonies in the region and has changed dramatically during the past two decades. The colony has increased both in species composition and overall numbers. Many of these changes remain unquantified. Northern Prairie is developing and assessing methods to estimate breeding populations of ground- and shrub-nesting waterbirds at Chase Lake. The goal is to develop reliable methods for estimating the size of breeding populations for different waterbird species and to provide protocols for monitoring colonial species at Chase Lake NWR. The methods will be applicable to other ...
Highly pathogenic avian influenza H5N1 remains a serious concern for both poultry and human health. Wild waterfowl are considered to be the reservoir for low pathogenic avian influenza viruses; however, relatively little is known about their movement ecology in regions where HPAI H5N1 outbreaks regularly occur. We studied movements of the ruddy shelduck (Tadorna ferruginea), a wild migratory waterfowl species that was infected in the 2005 Qinghai Lake outbreak. We defined their migration with Brownian Bridge utilization distribution models and their breeding and wintering grounds with fixed kernel home ranges. We correlated their movements with HPAI H5N1 outbreaks, poultry density, land cover, and latitude in the Central Asian Flyway. Our Akaike Information Criterion analysis indicated that outbreaks were correlated with land cover, latitude, and poultry density. Although shelduck movements were included in the top two models, they were not a top parameter selected in AICc stepwise regression results.
Improving growth and survival of culture marine fish larvae: Striped trumpeter |i|(Latris lineata)|/i| a test case for Tasmania. CRC Final Report Project No 1D4 (FRDC2001/206)
Shooting has begun in Ontario on Chet Baker biopic Born To Be Blue with Ethan Hawke as the legendary jazz trumpeter. Written and directed by Canadian filmmaker Robert Budreau, the drama is inspired by Bakers rise, fall and eventual resurgence.
The tolerance of striped trumpeter, Latris lineata (Bloch and Schneider 1801) embryos to ozonated seawater was examined as a possible means of disinfection. The effect of a range of ozone doses and exposures (CT = concentration × exposure time) was tested at different stages of embryonic development. Three-day-old embryos two-thirds developed around the yolk were exposed for 0.5, 1 or 5 min to ozone concentrations of 0.5, 1, 2 and 5 mg O3 l−1 in a fully orthogonal factorial design. For each treatment there were four replicate 250 ml containers that each received 100 ± 15 embryos. There was no significant difference in hatching success between control-treated embryos or embryos ozonated at 0.5 or 1 mg O3 l−1 for 0.5, 1 or 5 min (P , 0.05). However, hatching success was significantly reduced when embryos were treated with 2 or 5 mg O3 l−1 for 5 min or 5 mg l−1 O3 for 1 min (P , 0.05). The tolerance of embryos to 0, 0.5 or 2 mg O3 l−1 for 1 min at different stages of development (Day 0, ...
Although it is on average about seven to eight cm shorter from beak to tail than the California condor, the Andean condor is larger in wingspan, which ranges from 270 to 320 cm (8 ft 10 in to 10 ft 6 in).[3] It is also typically heavier, reaching a weight of 11 to 15 kg (24 to 33 lb) for males and 8 to 11 kg (18 to 24 lb) for females.[15] Overall length can range from 100 to 130 cm (3 ft 3 in to 4 ft 3 in).[15] Among standard measurements, the wing chord is 75.7-85.2 cm (29.8-33.5 in), the tail is 33-38 cm (13-15 in) and the tarsus is 11.5-12.5 cm (4.5-4.9 in).[3] Measurements are usually taken from specimens reared in captivity.[3] The mean weight is 11.3 kg (25 lb), with the males averaging about a kilogram more at 12.5 kg (28 lb), the females a kilogram less at 10.1 kg (22 lb). According to a recently published manual of avian body masses, the species possesses the heaviest average weight for any living flying bird or animal, ahead of competitors such as trumpeter swans (Cygnus buccinator) ...

11/17/2020 This is week nine of waterbird surveys at the refuge for the fall migration. Last weekend a strong front came through Wisconsin with 40+ mph winds and rain showers. This brought down more cranes and mallards. More than 80% of the marsh was frozen (1/2 ice) on this weeks survey. Most birds were congregated in the middle of the marsh in open water. Anticipated warmer weather through the beginning of next week will bring back the open water. Canada goose numbers decreased- about 20,000 were counted on the refuge this week. Fall harvest is nearly complete. Many geese and cranes were observed feeding in corn stubble surrounding the refuge. Dabbling ducks numbers increased this week -almost 68,000. A big influx of mallards made up 90% of that total -~61,000. The only other species seen in the thousands was green-wing teal. Northern shovelers, Northern pintails, American black ducks, and gadwall were seen in the hundreds. Diving duck numbers total about 900. Three species were seen in the ...
The Large Area Telescope (LAT), on board the Fermi Gamma-ray Space Telescope, has detected a transient gamma-ray source in the Galactic Plane: Fermi J2102+4542. Preliminary analysis of the Fermi-LAT data indicates that on the 13th and 14th of March 2010, the source was detected with a >100 MeV flux of (1.0 +/- 0.3) x 10^-6 ph cm^-2 s^-1 and (1.4 +/- 0.4) x 10^-6 ph cm^-2 s^-1, respectively (statistical only) -- corresponding significances on these days are 8 sigma and 6 sigma. A systematic uncertainty of 30% should be added to this number. There is no previously reported gamma-ray source at this location. Combining data for the period from Mar 12 0:0:0 UTC and ending Mar 16 ~8:30 UTC, the preliminary LAT position is (J2000.0): RA = 315.60 deg., Dec = 45.71 deg. (l, b = 86.96 deg, -0.55 deg) which is in the Cygnus region of our Galaxy. There is no previously reported EGRET or LAT gamma-ray source at this position. Within the 95% confidence error circle radius of 0.12 deg (statistical only) is the ...
Species-specific strategies for financing the costs of reproduction are well understood, forming a continuum ranging from high to low reliance on stored nutrients. Animals relying mostly on stored reserves are termed capital breeders, whereas income breeders rely mostly on concurrent intake when financing the costs of reproduction. The role and adaptive value of individual variation in these strategies remain elusive. Life-history theory posits that capital breeding should be favoured when offspring reproductive value peaks, typically occurring early in the season, and that current income should increasingly be used with progressing season. Because resource limitation may hamper flexible resource allocation, a corollary prediction is that only good-condition individuals may show the expected seasonal shift in resource use. To test this prediction, we examined stable isotopes (δ13C and δ15N) in blood and lipid-free egg yolk of breeding eider females (Somateria mollissima) from the Baltic Sea to
I will be the first to admit that putting the title of Swan Song on a piece about swans is a corny thing to do, but there was no other choice. I wanted to talk about swan songs specifically Tundra Swan songs- so what else could I do? It probably would have been more insightful and clever to label this as Call of the North, Tundra Tunes, or Winter Windpipes, but then again it really doesn t matter what I call it. Pygmalion was the original title of My Fair Lady and that didn t affect the stage or theatre success of the musical, did it? O.K. then, I m here to talk about Cygnus columbianus the Musical. As you might expect, Tundra Swans are visitors from the high north (the north slope of Alaska & the Yukon territories). They come south every winter to bide their time in the relative comfort of our southern cold season. Most of the migrating population flies to the east coast and Chesapeake Bay, but a significant number do their time here in the western end of Lake Erie at the mouth of the Detroit ...

The end result of this is that because Ive been getting the silent treatment for the past forty-eight hours, now I have loads of spare time!

The migratory bird season is in full swing and avid bird watchers have flocked to Surajpur wetland to sight the charismatic Common Teal, Red-crested Pochard, Ferruginous Pochard, Bar-headed Goose, Greylag Goose, Northern Shoveler and Gadwall. It is noon and some birds can be seen resting and preening their feathers in the morning while others are skittish and hide in the tall grasses or in the dense thicket of trees. Some other birds can be seen wading in the shallow waters. One can catch a glimpse of nests teetering on the treetops. ...

Their camaraderie is also appealing - they nest in colonies of up to 10,000 or more. The mothers line their nests with that same wonderful fluffy Eider down that lines our nests in the wintertime. Their independence is remarkable, too. The chicks leave the nest within a day of hatching and go straight to the water, already knowing how to dive and feed themselves. Imagine what it would be like being born knowing how to dive. Every year, we follow a new crop of Eiders as they grow from chicks to teenagers over the summer. In May or so, groups called crèches float along the coast composed of fluffy newborn chicks and several moms. The females are a soft brown in color, in contrast with the black and white males, which helps them camouflage while they incubate their eggs. In these large groups, the multiple moms can successfully chase off predators. One afternoon, we watched as a bald eagle harassed a crèche and was sure he would make off with one of the fuzzy ducklings, but the moms prevailed and ...

CIDRAP News) About 250 wild swans died of an H5 avian flu virus infection on the Volga River delta in southern Russia, according to an Agence France-Presse (AFP) report yesterday that cited Russian news agencies. Tests to determine if the strain was H5N1 had not been completed.. As a result of the swan die-off, a quarantine was being enforced in an area near the city of Astrakhan, AFP reported. ...
The main thing is to challenge yourself, Michael Gira explained in a Nowness video last month, and make work that surprises you and that has magic. And if you do the same thing over and over, there is no magic. You have to find a new way to do things. That mission statement has remained strong throughout Giras career, but its been especially evident in the second coming of his post-punk band Swans. Since their reformation in 2010, the group has produced some of their finest material yet by constantly refining it through endurance-testing road trips, grueling rehearsals, and Giras own raw demos. To reinforce the importance of that creative process, Swans will release a digital Oxygen EP on November 25th that features four distinct versions of its title track: a home recording, an acoustic take, a live cut, and a blustery radio edit by Mute founder Daniel Miller. In other Swans news-outside of their looming Filth reissue-UK fans can expect two major appearances in the months ahead: a ...

Cygnus Launch Status: Due to weather concerns, Orbital has decided to delay the Cygnus launch from Tuesday to no earlier than Wednesday, January 8th. However, Orbital estimates less than 50% chance of being Go on the 8th. The main concern is due to forecasted cold temperatures. The limiting component is the frangible joints on the Antares fairing. Their lower limit is 20 degrees F. Weather remains favorable for a roll out to occur Saturday evening.. Body Measures: Flight Engineer (FE)-6 Wakata, with operator assistance from FE-5 Mastracchio, set up cameras and cabin video, performed body marker instrumentation, and collected calibration and body pose photos and circumference measurements for his flight day 45 session. It is anticipated that body measurements will change due to microgravity and fluid shifts. The goal of this study is to gather preliminary data to better understand the magnitude and variability of these changes. This data is important to be able to determine the changes that may ...
The idea seems to be that you have an array of single stranded DNA attached to a gold chip. A dark matter particle transfers kinetic energy into a gold nucleus, sending it flying through the DNA array and severing the chemical bonds along its trajectory. The severed DNA is collected, amplified via PCR (a molecular biology technique for rapid DNA replication, for those who havent heard of it), and sequenced. Since each DNA strand in the array has a different sequence, the identity of the severed DNA strands provides a record of the 3-dimensional direction in which the gold nucleus traveled. This is then compared to the time of day to test the hypothesis that the earth travels into the dark matter field while rotating towards Cygnus, and away from it while rotating away from Cygnus ...

Cygnus NG-13 Launch Update: The NG-13 mission is currently scheduled for launch from NASA Wallops Launch Facility on Friday, February 14th at 2:43 pm CT. Cygnus is scheduled for ISS arrival and capture on Sunday, February 16th at 3:40 am CT. Following capture and berthing to the Node 1 nadir port, the crew will ingress S.S. Robert Henry Lawrence Jr and begin the transfer of time critical payloads to the ISS. The NG-13 resupply mission is part of the Commercial Resupply Services-2 (CRS-2) contract.. Payloads:. Bartolomeo preparation: Today, the crew installed the Bartolomeo break out harness installation behind the Human Research Facility (HRF) 2 rack in the Columbus Module COL1A4 location. In order to access the harness installation area behind the rack, the crew cleared stowage from the HRF2 rack front, de-mated the rack service umbilicals, and rotated the rack down. Once the Bartolomeo breakout harness was installed the crew restored the HRF2 rack to its nominal configuration.. Designed to ...

Two key differences between flying and flightless birds are the smaller wing bones of flightless birds[15] and the absent (or greatly reduced) keel on their breastbone. (The keel anchors muscles needed for wing movement.)[2]. Adapting to a cursorial lifestyle causes two inverse morphological changes to occur in the skeleto-muscular system: the pectoral apparatus used to power flight is paedorphically reduced while peramorphosis leads to enlargement of the pelvic girdle for running.[9] Repeated selection for cursorial traits across ratites suggests these adaptions comprise a more efficient use of energy in adulthood.[6] The name "ratite" refers to their flat sternum that is distinct from the typical sternum of flighted birds because it lacks the keel. This structure is the place where flight muscles attach and thus allow for powered flight.[14] However, ratite anatomy presents other primitive characters meant for flight, such as the fusion of wing elements, a cerebellar structure, the presence of ...

The trumpeter swan is the largest extant species of waterfowl. Adults usually measure 138-165 cm (4 ft 6 in-5 ft 5 in) long, though large males can exceed 180 cm (5 ft 11 in) in total length.[2][6][7][8] The weight of adult birds is typically 7-13.6 kg (15-30 lb). Possibly due to seasonal variation based on food access and variability due to age, average weights in males have been reported to range from 10.9 to 12.7 kg (24 to 28 lb) and from 9.4 to 10.3 kg (21 to 23 lb) in females.[2][9][10][11] It is one of the heaviest living birds or animals capable of flight. Alongside the mute swan (Cygnus olor), Dalmatian pelican (Pelecanus crispus), kori bustard (Ardeotis kori), and Andean condor (Vultur gryphus), it is one of a handful to weigh in excess of 10 kg (22 lb) between the sexes, and one survey of wintering trumpeters found it averaged second only to the condor in mean mass.[12][13] The trumpeter swan's wingspan ranges from 185 to 250 cm (6 ft 1 in to 8 ft 2 in), with the wing chord measuring ...
