Declines in populations of capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) have been reported from both Central Europe and the continuous boreal forests of Fennoscandia. While intensified land-use is assumed to be the underlying cause of these declines, the mechanisms are not yet understood. Predation is the proximate cause of mortality of eggs, chicks and adults throughout capercaillie and black grouse ranges, but the link between predation and habitat and/or climate change remains unclear. To investigate temporal trends in reproductive output of woodland grouse, we collated previously published and unpublished data of reproduction in capercaillie and black grouse throughout their ranges from 1930 to 2012. We show that, overall, reproductive success has decreased and stabilized at low levels in most regions whilst capercaillie reproductive output in Scotland is still declining. With todays net reproduction, capercaillie and black grouse adult survival is too low to compensate for
Establishment of a pheasant (Phasianus colchicus) spermatogonial stem cell line for the production of interspecies germline chimeras
Greater sage-grouse, Centrocercus urophasianus, have been a model system in studies of sexual selection and lek evolution. Mate choice in this species depends on acoustic displays during courtship, yet we know little about how males produce these sounds. Here we present evidence for previously undescribed two-voiced sound production in the sage-grouse. We detected this `double whistle (DW) using multi-channel audio recordings combined with video recordings of male behavior. Of 28 males examined, all males produced at least one DW during observation; variation in DW production did not correlate with observed male mating success. We examined recordings from six additional populations throughout the species range and found evidence of DW in all six populations, suggesting that the DW is widespread. To examine the possible mechanism of DW production, we dissected two male and female sage-grouse; the syrinx in both sexes differed noticeably from that of the domestic fowl, and notably had two sound ...
Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents.
2Numbers of black grouse Tetrao tetrix and their breeding success were therefore monitored at 20 sites in the north of England from 1996 to 2000. Ten treatment sites included areas where grazing was reduced before and during the study to , 1·1 sheep ha −1 in summer and , 0·5 sheep ha −1 in winter. Each was paired with a reference site that held sheep at two (summer) to three times (winter) the density on the experimental sites. The reduced grazing sites ranged from 0·4 to 3·2 km 2 in size and most were part of existing agreements within agri-environment schemes that had been in place for 1-5 years before 1996 ...
The Galliformes are a clade of bird species of cosmopolitan distribution that, with the Anseriformes, belong to the branch Galloanserae. The group have more than 270 living species and includes the megapodes, chachalacas, guans, curassows, turkeys, grouse, New World quails, pheasants, partridges and guineafowl. They are, with Neoaves, the two main lineages of Neognathae. Extinct species assignment follows the Mikkos Phylogeny Archive and Paleofile.com websites.

Among bird species, the most studied major histocompatibility complex (MHC) is the chicken MHC. Although the number of studies on MHC in free-ranging species is increasing, the knowledge on MHC variation in species closely related to chicken is required to understand the peculiarities of bird MHC evolution. Here we describe the variation of MHC class IIB (MHCIIB) exon 2 in a population of the Grey partridge (Perdix perdix), a species of high conservation concern throughout Europe and an emerging galliform model in studies of sexual selection. We found 12 alleles in 108 individuals, but in comparison to other birds surprisingly many sites show signatures of historical positive selection. Individuals displayed between two to four alleles both on genomic and complementary DNA, suggesting the presence of two functional MHCIIB loci. Recombination and gene conversion appear to be involved in generating MHCIIB diversity in the Grey partridge; two recombination breakpoints and several gene conversion ...
... is a new field of science that applies novel whole-genome sequencing technology to problems in conservation biology. Re-examining Patterns of Genetic Variation in Sage-grouse Using Genomic Techniques - Principal Investigator - Sara Oyler-McCance. The goal of this study was to use new comprehensive genomic markers to re-examine patterns of genetic variation in sage-grouse focusing on differences between Gunnison Sage-grouse, the Bi-State population of Greater Sage-grouse, and the rest of the range of Greater Sage-grouse. We found that by using genomic methods we were able to reveal that Gunnison Sage-grouse are much more diverged from Greater Sage-grouse than the Bi-State population of Greater Sage-grouse is from Greater Sage-grouse. This study confirms definitively that Gunnison Sage-grouse represent a distinct species and that the Bi-State is a distinct population of Greater Sage-grouse. This study also confirms that Gunnison Sage-grouse have much lower genomic diversity ...
Understanding the genetic basis of biological processes is a fundamental component of modern ecology and evolutionary biology studies. With the recent advent of next generation sequencing (NGS) technologies, it is now possible to perform large genome and transcriptome projects for ecologically important non-model species. In this thesis, I focused on the development and application of genomic resources of two non-model bird species, the black grouse (Tetrao tetrix) and the great snipe (Gallinago media). Using the chicken genome as a reference, I developed a reference guided NGS pipeline to assemble the complete draft genome of black grouse. The draft genome has a good coverage of the main 29 chromosomes of the chicken genome. The genome was used to develop a vast number of genetic markers. Comparing this genome with that of other species, I identified the genomic regions which were important for the lineage specific evolution of black grouse. I also sequenced and characterised the spleen ...
This study assessed the presence of sialic acid α-2,3 and α-2,6 linked glycan receptors in seven avian species. The respiratory and intestinal tracts of the chicken, common quail, red-legged partridge, turkey, golden pheasant, ostrich, and mallard were tested by means of lectin histochemistry, using the lectins Maackia amurensis agglutinin II and Sambucus nigra agglutinin, which show affinity for α-2,3 and α-2,6 receptors, respectively. Additionally, the pattern of virus attachment (PVA) was evaluated with virus histochemistry, using an avian-origin H4N5 virus and a human-origin seasonal H1N1 virus. There was a great variation of receptor distribution among the tissues and avian species studied. Both α-2,3 and α-2,6 receptors were present in the respiratory and intestinal tracts of the chicken, common quail, red-legged partridge, turkey, and golden pheasant. In ostriches, the expression of the receptor was basically restricted to α-2,3 in both the respiratory and intestinal tracts and in mallards

Results of recent studies showed that 2,3,4,7,8-pentachlorodibenzofuran (PeCDF) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) are equipotent in domestic chicken (Gallus gallus domesticus) while PeCDF is more potent than TCDD in ring-necked pheasant (Phasianus colchicus) and Japanese quail (Coturnix japonica). To elucidate the mechanism(s) underlying these differences in relative potency of PeCDF among avian species, we tested the hypothesis that this is due to species-specific differential binding affinity of PeCDF to the aryl hydrocarbon receptor 1 (AHR1). Here, we modified a cell-based binding assay that allowed us to measure the binding affinity of dioxin-like compounds (DLCs) to avian AHR1 expressed in COS-7 (fibroblast-like cells). The results of the binding assay show that PeCDF and TCDD bind with equal affinity to chicken AHR1, but PeCDF binds with greater affinity than TCDD to pheasant (3-fold) and Japanese quail (5-fold) AHR1. The current report introduces a COS-7 whole-cell binding ...
Serums from 838 ring-necked pheasants (Phasianus colchicus) reared on 28 Iowa game farms were tested for Mycoplasma gallisepticum specific antibodies. Two hundred serums reacted with tube agglutination antigen, but only eight were confirmed with the hemagglutination-inhibition test.
The aim of this study was to determine the chemical composition and fatty acid composition of the Musculus pectoralis major of wild and farmed pheasants (Phasianus colchicus sp. L.). The chemical composition did not show a statistically significant difference (p>0,05). Pheasant breast muscle contains 72% water, 0,5-0,7% fat, 26% protein and 1,3% ash. The most abundant fatty acids are oleic (C18:1), palmitic (C16:0), linoleic (C18:2) and stearic (C18:0). The content of saturated fatty acids (SFA) did not differ significantly in farmed and wild pheasants, while the increase of monounsaturated fatty acids (MUFA), mainly because of high content of oleic acid, had farmed pheasant. A higher proportion of polyunsaturated fatty acids (PUFA) had wild pheasants. The n-6 /n-3 ratio did not differ regarding of the method of cultivation and was 4,76 in farmed and 4,82 in wild pheasants. Phesant meat is a valuable food product thanks to high protein and low fat content ...
Toxoplasma gondii is an intracellular protozoan parasite infecting almost all warm-blooded animals, including birds, with a worldwide distribution. Surveys of T. gondii infection in wild birds have been reported extensively in the world, but little is known of T. gondii infection in peafowls worldwide. This study was performed to determine the seroprevalence of T. gondii infection in peafowls in Yunnan Province, southwestern China. Sera from 277 peafowls, including 272 blue peafowls (Pavo cristatus) and 5 green peafowls (Pavo muticus) originated from two geographic areas in Yunnan Province were assayed for T. gondii antibodies using the modified agglutination test (MAT). Specific T. gondii antibodies were detected in 35 of 277 (12.64%) peafowls (MAT titer ≥ 1:5). Seropositive birds were found in both species, 33 in 272 blue peafowls and 2 in 5 green peafowls. There was no significant difference in T. gondii seroprevalence between the adolescent birds (6.74%) and the adult birds (6.67%) (P | 0.05). The
The Northern Red-legged Frog is a medium-sized (7-10 cm) reddish-brown and black-speckled frog that gets its name from the translucent red undersides of its hind legs. Its range extends along the Pacific coast, west of the Coast and Cascade Mountains from southwestern British Columbia to northwestern California. In British Columbia, the Northern Red-legged Frog occurs mainly throughout the forested lowlands (| 1200 m elevation) of Vancouver Island, the adjacent Gulf Islands, along the mainland coast as far north as Kingcome Inlet, and in the Lower Fraser Valley to Hope. The Northern Red-legged Frog requires structurally complex wetlands (i.e., the ratio of emergent vegetation to open water) and forest habitats (i.e., abundant canopy cover, downed wood and litter) in a suitable spatial configuration to complete its life cycle.

Grouse and ptarmigans Family Tetraonidae Grouse, ptarmigans, and prairie chickens are all chicken-like birds with short, curved, strong bills, part of the family Tetraonidae. This group includes 25 species residing mostly in North America. They are mainly ground-dwellers and have short, rounded wings for brief flights. They are well adapted to winter by growing feather "snowshoes" on their feet and roosting beneath the snow. They range in size from the 13-inch white-tailed ptarmigan to the 28-inch sage grouse. Their plumage is dense and soft and is most commonly found in shades of red, brown, and gray to camouflage to the ground. They are polygamous and male courtship behavior includes strutting and dancing and aggressive fighting for possession of females. The typical clutch size is between seven and 12 eggs. Turkeys Family Meleagrididae Turkeys are large, long-legged birds that can grow up to four feet in height and weigh up to 30 lbs in the wild. They have a long, broad, rounded tail with ...

Perdicinae is a subfamily of birds in the pheasant family, Phasianidae, regrouping the partridges, Old World quails, and francolins.[1] Although this subfamily was considered monophyletic and separated from the pheasants, tragopans, junglefowls, and peafowls (Phasianinae) till the early 1990s,[1][2] molecular phylogenies have shown that these two subfamilies actually constitute only one lineage. For example, some partridges (Perdix genus) are more closely affiliated to pheasants, whereas Old World quails and partridges from the Alectoris genus are closer to junglefowls.[3][4] Perdicinae is a non-migratory Old World group. These are medium-sized birds, and are native to Europe, Asia, Africa, and the Middle East. They are ground-nesting seed-eaters. The subfamily includes the partridges, the snowcocks, the francolins, the spurfowl and the Old World quail. ...
The gamebird shooting industry involves the shooting of the native grey partridge and red grouse in addition to non-native gamebirds such as red-legged partridge and pheasant. These populations are managed for shooting and there is no evidence to suggest that shooting has resulted in population declines. In order to enhance gamebird populations, a range of native birds and mammals are killed legally as part of pest control campaigns. These species are generalist predators, including foxes, stoats, weasels, carrion crows and magpies. There is no evidence to suggest that this has an adverse affect on populations of these species, although little information is available on which to assess the impacts of killing stoats and weasels. The illegal persecution of native birds of prey, especially for the threatened hen harrier in England, has been associated with game rearing interests and remains a serious problem.. ...

For herbivores, maximizing energy intake is limited by the relatively low nutritional quality of plants and high concentrations of potentially toxic plant secondary metabolites (PSMs). Although several studies have demonstrated that herbivores prefer diets with the highest nutrient and lowest PSM constituents, these studies are primarily confined to laboratory feeding trials due to the difficulty of observing diet selection in free ranging herbivores. Field observations have demonstrated that pygmy rabbits (Brachylagus idahoensis) and greater sage-grouse (Centrocercus urophasianus), both facultative specialists on sagebrush (Artemisia spp.), forage on specific sagebrush plants more than others within a foraging patch. I used these species to test the hypothesis that sagebrush plants heavily browsed (browsed) by pygmy rabbits and sage-grouse are higher in crude protein and lower in PSMs and are preferred to rarely browsed plants (unbrowsed). To test the hypothesis, I analyzed crude protein, digestibility

TY - JOUR. T1 - The impact of pelvic lateral rotation on hindlimb kinematics and stride-length in the red-legged running frog, Kassina maculata. AU - Collings, Amber. AU - Porro, Laura. AU - Hill, Cameron. AU - Richards, Christopher T.. PY - 2019/5/8. Y1 - 2019/5/8. N2 - Some frog species, such as Kassina maculata (red-legged running frog), use an asynchronous walking/running gait as their primary locomotor mode. Prior comparative anatomy work has suggested that lateral rotation of the pelvis improves walking performance by increasing hindlimb stride length; however, this hypothesis has never been tested. Using non-invasive methods, experimental high-speed video data collected from eight animals were used to create two three-dimensional kinematic models. These models, each fixed to alternative local anatomical reference frames, were used to investigate the hypothesis that lateral rotation of the mobile ilio-sacral joint in the anuran pelvis plays a propulsive role in walking locomotion by ...

Summary: Wing-assisted incline running (WAIR) is a form of locomotion in which a bird flaps its wings to aid its hindlimbs in climbing a slope. WAIR is used for escape in ground birds, and the ontogeny of this behavior in precocial birds has been suggested to represent a model analogous to transitional adaptive states during the evolution of powered avian flight. To begin to reveal the aerodynamics of flap-running, we used digital particle image velocimetry (DPIV) and measured air velocity, vorticity, circulation and added mass in the wake of chukar partridge _Alectoris chukar_ as they engaged in WAIR (incline 65?85°; N=7 birds) and ascending flight (85°, N=2). To estimate lift and impulse, we coupled our DPIV data with three-dimensional wing kinematics from a companion study. The ontogeny of lift production was evaluated using three age classes: baby birds incapable of flight [6?8 days post hatching (d.p.h.)] and volant juveniles (25?28 days) and adults (45+ days). All three age classes of ...
Meat microorganisms are one of the main sources of food borne illnesses, posing serious challenges in developing countries including Ghana. This study determined the microbial load of 150 fresh and smoked meat samples (50 beef, 50 pork and 50 guinea fowl meat) collected from meat retail shops in the Bolgatanga Municipality. Beef samples were obtained from Stanbic, Starlife, Central mosque, Jolly hut, and Mobile clinic shops; pork samples were obtained from Soe, Atulbabisi, Pobaga, Zobisi, and Dagbew shops; guinea fowl samples were obtained from Atibire, Next door, Comeci, Speed link and Ojam shops. The surface of fresh and smoked meat samples were swabbed using cotton swabbed and stored under 4°C for transportation to the Spanish Laboratory of the University for Development Studies, Nyankpala. The meat samples were analyzed immediately on arrival at the Laboratory under aseptic conditions for total aerobic bacteria. The surrounding environments of the retail shops were also observed. Total ...
The common name given to this bird in the Eastern and Middle Districts of our Union is that of Quail, but in the Western and Southern States, the more appropriate appellation of Partridge is bestowed upon it. It is abundantly met with in all parts of the United States, but more especially towards the interior. In the States of Ohio and Kentucky, where they are very abundant, they are to be seen in the markets, both dead and alive, in large quantities. This species performs occasional migrations from the north-west to the south-east, usually in the beginning of October, and somewhat in the manner of the Wild Turkey. For a few weeks at this season, the north-western shores of the Ohio are covered with flocks of Partridges. They ramble through the woods along the margin of the stream, and generally fly across towards evening. Like the Turkeys, many of the weaker Partridges often fall into the water, while thus attempting to cross, and generally perish; for although they swim surprisingly, they have ...

Over the weekend I attended a conference at the University of Chicago on The Biological Basis of Preferences and Behavior, and Balazs Szentes stole the show with a new theory of the peacocks tail. In Balazs theory a world without large and colorful peacock plumage is simply not stable.. A large tail is an evolutionary disadvantage: it serves no useful purpose and it slows down the male and makes him conspicuous to predators. So why do genes for large tails appear and take over the population of male peacocks? Balazs answer is based on matching frictions in the peacock mating market. Suppose female peacocks choose which type of male peacock to mate with: small or large tails. Once the females sort themselves across these two separate markets, the peacocks are matched and they mate.. The female peacocks are differentiated by health, and within a peacock couple health partially compensates for the disadvantageous tail. In the model this means that healthy females who mate with big-tailed ...

You are now presented, kind reader, with a species of Grouse, which, in my humble opinion, far surpasses as an article of food every other land-bird which we have in the United States, except the Wild Turkey, when in good condition. You must not be surprised that I thus express an opinion contradictory to that of our Eastern epicures, who greatly prefer the flesh of the Pinnated Grouse to that of the present species, for I have had abundant opportunity of knowing both. Perhaps, after all, the preference may depend upon a peculiarity in my own taste; or I may give the superiority to the Ruffed Grouse, because it is as rarely met with in the Southern States, where I have chiefly resided, as the Pinnated Grouse is in the Middle Districts; and were the bon-vivants of our eastern cities to be occasionally satiated with the latter birds, as I have been, they might possibly think their flesh as dry and flavourless as I do. The names of Pheasant and Partridge have been given to the present species by ...

Hatchling Australian brush turkeys consistently out-performed older birds as they climbed a variable-pitched inclined ramp, built to emulate inclined objects that birds encounter in nature (e.g. earthed mounds, trees, boulders, cliffs). Although capable of true flight, the day they emerge from their ground nest, brush turkeys, like other Galliformes, preferentially used WAIR to ascend to an elevated refuge. Ricklefs [3] argued that precocial species should be adept at burst locomotion. In the wild, young brush turkeys are often exposed to intense predation (,15% may survive the first three weeks), and they seek elevated refuges when threatened or for roosting [2]. As adults, brush turkeys and other Galliformes can outrun many predators and use their wings only for brief escape flights. To avoid predators, young brush turkeys must negotiate a highly variable terrestrial environment on their own. Our data suggest that one trait promoting early incline-running performance is their extraordinarily ...
Thanks for that David. I wasnt trying to stifle discussion, merely suggesting that this is an area where different outlooks may actually be responsible for our differing conclusions rather than simply evidence. Im not going to be dogmatic in saying that either is right or wrong, but we certainly view things differently. You could be right, perhaps I am misunderstanding. But I think I do understand, I just come to a different conclusion. I do realise that cladistics and phylogenetic nomenclature are different things. But I was (perhaps not very clearly) trying to make a somewhat different point, but I wont belabour that. As for what sort of scientist I am - well I think you were joking, so Ill leave that one - lol.. Any way on to more interesting stuff..

The Crested Partridge ranges from the Malaysian peninsula to Borneo and Sumatra, and is found in tropical lowland evergreen forests. The Crested Partridge is recognizable by its vivid red legs and circle of red skin around the eyes of both sexes, while the male also has a tall red crest on its head. Like most gamebirds, it forages on the ground for fruit, small lizards, insects and seeds; however, the young are fed by their parents, which is unusual for Galliformes. The Crested Partridge is known to associate with wild pigs, feeding on discarded fruits that are normally too large for it to tackle ...
The wyandotte bantam. This version is lighter than its larger counterpart, therefore create less damage to flowerborders, manicured lawns and enclosures. Other than this, they are a replica of their large counterpart.. Cockerels weigh about 1.7kg while hens weigh around 1.3kg. Wyandotte bantams come in a similar array of colours, but my favourite must be partridge bantams.. Partridge wyandottes are very versatile. Like all other wyandottes, they are excellent egg producers, but are also a successful colour in the showring. Unlike colours such as whites and lavenders, they dont get dirty, but are still very pretty birds.. I recommend these birds for first time owners and first time exhibitors, but even if you have owned chickens for many years, these birds still make a delightful addition in any garden..

High mountain systems are predicted to be especially vulnerable to the impact of climate change, with the climatically-constrained tree limit rapidly shifted upslope. In turn, the impact of upward treeline migration on mountain-dwelling bird species is expected to significantly reduce habitat suitability. We developed the first projection of the expected climate-driven rise of the whole treeline (19,256 km) of the Italian Alps. The study area extends over 20,700 km2, ranging over 550 km in longitude and 320 km in latitude. We then investigated how much the expected treeline rise will induce a) shrinking and shifting of the elevation range and b) loss in suitable habitat for the flagship species rock ptarmigan, an alpine bird species dwelling above the treeline and, similarly to many other alpine species, highly vulnerable to treeline rise. We also investigated the potential gain in suitable habitat for rock ptarmigan due to the climate-driven upshift in the uppermost thermal limit. At lower ...
