Categorisation of cats: Managing boundary felids in Aotearoa New Zealand and Britain

Abstract Management of domestic and wild animals is an integral part of conservation and is often based on how an animal is categorised. For example, feral cats are often killed, while valued companion cats and native wildcats are protected. Drawing on qualitative research and using the concept of boundary‐work, this paper examines the complex categorisation and management of cats within conservation in Britain and Aotearoa, New Zealand (NZ). We examine how, both in theory and in practice, valued companion and wildcats are distinguished from unprotected feral cats, and in‐between categories of stray and hybrid cats. We demonstrate that stakeholders draw boundaries between cat categories differently. These differences in boundary‐drawing reflect the inherent blurriness of category boundaries, practical challenges and, importantly, differences in values, in particular whether priority is placed on the life of the cat or the cat's potential victim, particularly native or game birds. This can mean that laws outlining protections for specific categories of animals have limited effect if, in practice, those encountering cats draw boundaries differently. This paper also reports on important differences between the two case studies. In NZ, even cat advocates support the humane killing of unambiguously feral cats while this is less true in Britain. Furthermore, due to the nature of the contexts, conservationists in NZ are more inclined to assume that ambiguous cats are feral whereas conservationists in Britain are more inclined to assume that they are wildcats. This paper demonstrates that values not only shape people's perceptions and treatment of animals but also how they draw boundaries between them. This finding may have important implications for understanding other controversies in conservation and animal management. Read the free Plain Language Summary for this article on the Journal blog.

Diagnostic Detection of H7N3 Low Pathogenicity Avian Influenza in a Commercial Game Bird Flock.

Low pathogenicity avian influenza (LPAI) H7N3 was diagnosed in a flock of commercially raised Japanese quail (Coturnix japonica) breeder hens. The birds were submitted with an initial complaint of a drop in egg production and watery droppings. Initial PCR testing of the flock for avian influenza (AI) was negative; however, mortality started increasing drastically, prompting further examination and the submission of more birds to the diagnostic laboratory. On antemortem examination, the birds appeared lethargic, with ruffled feathers, and had labored breathing. Gross examination revealed poor body condition, moderate dehydration, splenomegaly, ovarian regression, and airsacculitis. Several hens produced thin-shelled and shell-less eggs. Microscopically, lymphoplasmacytic encephalitis with neuronal cell necrosis, fibrinoheterophilic pneumonia, and splenic lymphoid depletion with amyloid deposition were seen. AI virus was detected in a follow-up submission and characterized as LPAI H7N3. Quail are a species of interest in the pathobiology of avian influenza viruses, underlined by the ability to serve as an amplification host.

GAME BIRDS IN THE ECONOMY OF THE POPULATION OF BEREZOV (BASED ON THE RESULTS OF ARCHAEOZOOLOGICAL ANALYSIS)

Based on the evidence from osteological collection of birds (over 7,000 specimens), the hunting of game by the population of the town of Berezov in Modern period was reconstructed. The study identified species composition of game birds and conducted an analysis of the ratio of skeletal elements, fragmentation of bones, and external influences. The main purpose of bird hunting was to obtain an additional source of meat for the population of the town. Over time, the relative significance of poultry in the diet of the urban population decreased, but the intensity of game hunting remained constantly high. The game was hunted all year round. Spring-summer hunting for waterfowl was a dominant type. In winter, they hunted mainly for wood grouse and ptarmigan. Based on the average weight of each species, the authors calculated the potential amount of meat that can be obtained from the hunting for the three main groups of birds. It is shown that in the cold season, the supply of additional meat products from bird hunting decreased almost threefold compared with the spring-summer time.

The Sandringham Estate: the Prince of Wales’s 1862 purchase and implications for local people, wildlife and landscape

Abstract The Sandringham Estate was purchased in 1862 by the Prince of Wales to be his home away from London. This article uses a variety of sources to chart the changes to the estate as the prince developed his new holding. The acquisition required staff at all levels and in many and varied roles, which gave opportunities to local people and to those who moved in from further away. The countryside changed dramatically too with new plantations of trees and significantly increased rearing of game birds. There were benefits for the local population in having a royal landlord but there was also tension related to the prince’s predilection for blood sports and his level of control. The hitherto nearly invisible lower ranks of staff on this royal estate come to the fore in this article, which is a striking example of ‘history from below’ set immediately beside the royal family.

Status and Diversity of Ornithofauna in Joggers Park, Lucknow, Uttar Pradesh, India

The present study was done to account for the status and diversity of ornithofauna of Joggers Park, Lucknow, U.P., India. The field explorations were carried out from September 2021 to August 2022. During the period of study, a total of 62 species of ornithofauna were identified which belonged to 13 orders and 32 families. The order Passeriformes had a maximum number of bird count (34 species) belonging to 16 families. The least number of bird species was recorded in orders Strigiformes, Charadriiformes, Apodiformes, and Galliformes each containing 1 species. All the 62 avian species reported in Joggers Park come under the least concerned category of IUCN. Out of the total species, 49 species were resident and 13 Residents were Migratory (RM).

Evaluation of the host specificity of Eimeria uekii and Eimeria raichoi for Japanese rock ptarmigans by oocyst transfer to taxonomically related birds.

Eimeria spp. are protozoan parasites that are commonly found in a broad range of vertebrate hosts. These parasites generally exhibit strict host specificity, but some Eimeria spp. can infect groups of closely related species such as species within a genus or family. Compared with Eimeria spp. that infect livestock, limited information is available about such infections in wild animals including data on host specificity, virulence, and prevalence. The Japanese rock ptarmigan, Lagopus muta japonica, is an endangered bird belonging to the family Phasianidae, order Galliformes, and inhabits only alpine areas of Japan. In conservation efforts for these birds, two Eimeria spp., E. uekii and E. raichoi, were frequently detected. Here, we examined cross-transmission of the parasites to other bird species to characterize their infectivity as well as the development of experimental bird models to contribute to conservation programs by the oocyst transfer. Consequently, among the examined eight bird species (chickens, Japanese pheasants, turkeys, chukar partridges, quails, helmeted guineafowls and ducks), only turkeys (family Phasianidae, order Galliformes) could be infected with E. raichoi. However, the number of oocysts per feces was relatively low, and few parasites in the intestinal mucosa could be found by histopathological analyses. These results might indicate that E. uekii and E. raichoi are highly adapted to Japanese rock ptarmigans that inhabit the alpine zone although further studies are anticipated.

Review of the legal and regulatory history of lead in hunting

AbstractIn the United States, regulations to restrict the use of lead in ammunition have evolved at both the federal and state levels since lead shot was banned for hunting waterfowl nationwide by federal regulation in 1991. Prior to 1991, most of the effort and discussions were focused on reducing lead ingestion by wildlife from, and finding alternatives for, shotgun ammunition i.e., ammunition firing multiple small projectiles from one shell. Shotgun ammunition is often used for hunting small game mammals and birds. Since then, much, but not all, of the focus has shifted to reducing lead ingestion by wildlife from, and finding alternatives for, rifle ammunition i.e., ammunition firing a single projectile. Rifle ammunition is often, but not exclusively, used for hunting large game. Herein I will review the history of regulating lead in hunting ammunition in the U.S., and discuss some of the social, scientific, economic, and technological issues regarding switching from lead to nonlead alternatives.

At a fine scale, hardwood patches support wildlife diversity in longleaf pine woodlands

AbstractRestoring and maintaining biodiversity in a changing world is increasingly challenging due to the competing needs of species for suitable space and resources. One ecosystem that has seen considerable anthropogenic changes in extent and structure is the longleaf pine (Pinus palustris) ecosystem. Understanding how wildlife responds to restoration is important to informing forest restoration and conservation. We monitored game birds and mid‐large‐sized mammal occupancy in and around hardwood patches embedded within a longleaf pine woodland at The Jones Center at Ichauway in Newton, GA. We found that 11 species use the transition zone between the longleaf pine and hardwood hammocks. Gray squirrels (Sciurus carolinensis), Virginia opossums (Didelphis virginiana), and nine‐banded armadillos (Dasypus novemcinctus) occupancy increased along the gradient while fox squirrel (Sciurus niger) declined. Our results suggest that oak patches and transitional zones are important to maintaining biodiversity within the longleaf pine ecosystem.

Effects of human and nonhuman predation risk on antipredator movement behaviors of an upland game bird

AbstractPredators elicit antipredator behaviors such as proactive and reactive movements in prey, but both are rarely investigated simultaneously. Impacts of human predation risk on antipredator behaviors can be greater than those of nonhuman predators, resulting in increased effects on populations and community structure. We compared the influence of human and nonhuman predation risk on proactive and reactive antipredator movement behaviors of male Eastern wild turkeys (Meleagris gallopavo, hereafter turkey). We used simultaneously collected GPS locations from 31 turkeys and 36 coyotes (Canis latrans) to investigate the antipredator behavior of turkeys to coyotes. To assess antipredator behaviors of turkeys to hunters, we used 1661 hunting tracks collected while monitoring 109 turkeys. For proactive movements, we quantified how predation risk influenced resource selection. To investigate reactive movements, we quantified changes in movement behavior of turkeys after encountering hunters and coyotes. Coyote and turkey home range overlap was high, but lack of core area overlap, encounters, and similar resource selection suggested the use of different areas on the landscape. Turkeys selected areas associated with decreased coyote risk and closer to hardwoods. Coyotes preferred shrubs and open areas, suggesting turkeys avoided coyote risk and the habitats coyotes preferred. We detected 17 coyote and turkey contacts, and the probability of contact decreased by 16.6% for every 100 m farther from a forest edge. Turkeys did not display reactive movement behaviors after a direct encounter with coyotes, as step lengths were similar prior to and after encounters, which did not differ from random step lengths. After hunting, turkeys selected areas farther from public access points and closer to private property, suggesting proactive avoidance of hunter risk. We detected 31 hunter and turkey contacts; increased step lengths after hunter contacts suggested fleeing behavior. The probability of a hunter–turkey contact decreased by 5.5% for every 100 m farther from a secondary road. Antipredator movement behaviors by turkeys suggest coyote risk to be low over a broad temporal window, while hunter risk is high for a narrow temporal window. We provide insight into how human‐induced fear can cause antipredator behavioral responses greater than nonhuman fear, potentially causing changes in species distribution and community structure.

A chromosome-level genome assembly for the Rock Ptarmigan (Lagopus muta).

The Rock Ptarmigan (Lagopus muta) is a cold-adapted, largely sedentary, game bird with a Holarctic distribution. The species represents an important example of an organism likely to be affected by ongoing climatic shifts across a disparate range. We provide here a high-quality reference genome and mitogenome for the Rock Ptarmigan assembled from PacBio HiFi and Hi-C sequencing of a female bird from Iceland. The total size of the genome is 1.03 Gb with a scaffold N50 of 71.23 Mb and a contig N50 of 17.91 Mb. The final scaffolds represent all 40 predicted chromosomes, and the mitochondria with a BUSCO score of 98.6%. Gene annotation resulted in 16,078 protein-coding genes out of a total 19,831 predicted (81.08% excluding pseudogenes). The genome included 21.07% repeat sequences, and the average length of genes, exons, and introns were 33605, 394, and 4265 bp, respectively. The availability of a new reference-quality genome will contribute to understanding the Rock Ptarmigan's unique evolutionary history, vulnerability to climate change, and demographic trajectories around the globe while serving as a benchmark for species in the family Phasianidae (order Galliformes).

Landowner and biologist perceptions of game bird predators and management

AbstractNest survival has been identified as one of the most influential vital rates causing population change in game birds, and depredation, often influenced by habitat loss and fragmentation, is the primary cause of nest failure of upland game birds. We were interested in quantifying and comparing the perspectives of landowners and biologists in South Dakota regarding complex predator‐prey interactions to improve communication and management efficacy. We developed a questionnaire regarding the following: 1) general attitude statements about game bird species; 2) perceived impacts of 9 factors (e.g., development, pollution, predators) and 13 potential predators on game bird abundances; and 3) attitude statements regarding use of lethal predator control and nesting habitat management practices. A cluster analysis using landowner attitude statements about predator management identified 3 landowner segments that had strong (most supportive; 37%), moderate (moderately supportive; 35%), or weak (least supportive; 28%) attitude statements about lethal predator control. Landowner segments most supportive and moderately supportive of predator control rated predators as the primary negative factor impacting game bird abundances and agreed that predators were the primary cause of game bird abundance declines, whereas the landowner segment least supportive of predator control rated habitat loss as the top factor and disagreed that predators were the primary cause of game bird declines. Biologists rated habitat loss as the top factor negatively impacting game bird abundances and disagreed that predators were the primary cause of game bird abundance declines. Thus, when considering the effectiveness of strategies to reduce nest depredation, most landowners focused on the direct cause of nest failures (predators), whereas biologists focused on an indirect cause (habitat loss). Perception differences among these groups emphasizes the need for better communication on proximate and ultimate factors affecting game bird populations and how these differences may impact management decisions.

The Effect of Rearing System on Plumage Quality and Foot-Pad Dermatitis in Guinea Fowls and Pheasants

This study aims to determine welfare parameters such as foot-pad dermatitis (FPD) and plumage quality (PQ) scores at different slaughter ages in barn and free-range rearing systems for guinea fowl and pheasants. The birds randomly distributed with half of 200 Pheasant and 200 guinea fowl chicks were reared in both indoor and free-range systems. Game birds were examined for both FPD score and feather score (PQ) at 6, 12, 14, 16 and 18 weeks of age. The litter moisture content was also measured at 14, 16 and 18 weeks of the growing period. In guinea fowls, litter moisture content differed significantly according to the rearing system (P0.05). In terms of FPD, there was no difference in guinea fowl according to the rearing system, gender and slaughter age, but there was a difference in pheasants according to the slaughter age. In guinea fowl, the head PART feather quality was lower than the barn system (P

Reference genome of the Virginia rail, Rallus limicola.

The Virginia rail, Rallus limicola, is a member of the family Rallidae, which also includes many other species of secretive and poorly studied wetland birds. It is recognized as a single species throughout its broad distribution in North America where it is exploited as a game bird, often with generous harvest limits, despite a lack of systematic population surveys and evidence of declines in many areas due to wetland loss and degradation. To help advance understanding of the phylogeography, biology, and ecology of this elusive species, we report the first reference genome assembly for the Virginia rail, produced as part of the California Conservation Genomics Project (CCGP). We produced a de novo genome assembly using Pacific Biosciences HiFi long reads and Hi-C chromatin-proximity sequencing technology with an estimated sequencing error rate of 0.191%. The assembly consists of 1,102 scaffolds spanning 1.39 Gb, with a contig N50 of 11.0 Mb, scaffold N50 of 25.3 Mb, largest contig of 45 Mb, and largest scaffold of 128.4 Mb. It has a high BUSCO completeness score of 96.9% and represents the first genome assembly available for the genus Rallus. This genome assembly will help resolve questions about the complex evolutionary history of rails and evaluate the potential of rails for adaptive evolution in the face of growing threats from climate change and habitat loss and fragmentation. It will also provide a valuable resource for rail conservation efforts by quantifying Virginia rail vagility, population connectivity, and effective population sizes.

Validation of an LC-MS/MS method for assessment of fenbendazole sulfone drug residue in northern bobwhite liver.

The Northern Bobwhite (Colinus virginianus) is an economically important game bird within the Rolling Plains Ecoregion. Within this region, bobwhite is experiencing extreme cyclic population fluctuations which are resulting in a net decline in total population. It is suspected that within this region two helminth parasites, an eyeworm (Oxyspirura petrowi) and a cecal worm (Aulonocephalus pennula), are contributing to this phenomenon. However, this has been difficult to study as the primary mode of investigation would be the deployment of anthelmintic treatment. Unfortunately, no registered treatments for wild bobwhite currently exist. Thus, utilizing an anthelmintictreatment for wild bobwhite would require registration of that treatment with the U.S. Food and Drug Administration (FDA). As bobwhite are game birds that are hunted, they are considered food-producing animals to the FDA, and as such require the assessment for the withdrawal of the drug residues to be assessed for human food safety. In this study, we optimized and validated a bioanalytical method for the quantification of fenbendazole sulfone in bobwhite following the U.S. FDA Center for Veterinary Medicine Guidance for Industry #208 [VICH GL 49 (R)] for assessment of fenbendazole sulfone drug residue in Northern bobwhite liver. The official method for quantifying fenbendazole sulfone in domestic chicken (Gallus gallus) was adapted for use in bobwhite. The validated method quantitation range is 2.5-30 ng/mL for fenbendazole with an average recovery of 89.9% in bobwhite liver.

Molecular detection of cestoda in black francolin (Francolinus francolinus) of Babylon Province, Iraq

Cestodes or tapeworms (Class Cestoda, phylum Platyhelminthes) are widespread parasites of birds, as they cause various damages, which may lead to the death of their hosts, especially when the infection is severe. The Black Francolin belongs to the Phasianidae family of pheasants and, in the order Galliformes, the gallinaceous birds, and it is called Francolinus francolinus. Considering it as a local bird in Asia, it was referred to as the black partridge. The current study was conducted from January to October 2019 to determine the Cestoda infections within F. francolinus. Thirty-five birds from F. francolinus were examined for the presence of cestoda, of which 17 birds (48.57%) were infected with cestoda parasites. Molecular diagnosis based on sequences of cytochrome c oxidase 1 (COI) gene regions was performed to confirm the diagnosis of this cestoda. This revealed a close identification of up to 93.44-100% for COI gene regions with other cestoda species obtained from GenBank. Phylogenetic analysis supported the placement of this species within three families, Davaineidae, Taeniidae, and Hymenolepididae, with close relationships to the previously described species of Raillietina sp., R. mahnerti, R. hymenolepidoides, Ophryocotyloides dasi, Rodentolepis nana and Hydatigera parva based on the COI gene regions. This is the first study in Iraq to diagnose Cestoda in birds by molecular methods, where five species of cestoda parasitic on F. francolinus were recorded for the first time in Iraq.

Chukar partridge in northern Iraq: A review article

Iraqi Sulaymaniyah is a treasure land of wildlife, especially avian species. Most of this treasure is not discovered, and even the guidance map is not completed yet. The geographical area of Sulaymaniyah is suitable for many types of wildlife animals, including Chukar partridges, locally known as Khasa Kaw. The Chukar partridge is present in many countries in the Middle East region, but there is a subspecies in the northern of Iraq. The Sulaymaniyah nature is a natural habitat for this fantastic bird, seen in the valleys and around water springs throughout the region. Also, Chukar partridges are used as game birds and raised as pets or for fighting between the males. Unfortunately, there is no detailed scientific study on this bird, even though it is one of the most common and beloved birds. This article provides information on the history of the bird, its life cycle, behavior, taxonomy, distribution, sex, and age determination of Chukar partridges. It also mentions the most common diseases of chukar partridge and its natural predators.

Assessing Global Efforts in the Selection of Vertebrates as Umbrella Species for Conservation.

The umbrella-species strategy has been proposed as an attainable tool to achieve multi-species and community conservation with limited investment. There have been many umbrella-related studies since the concept's inception; thus, a summary of global study efforts and recommended umbrella species is important for understanding advances in the field and facilitating conservation applications. Here, we collated 213 recommended umbrella species of terrestrial vertebrates from 242 scientific articles published during 1984-2021 and analyzed their geographic patterns, biological features, and conservation statuses to identify global trends in the selection of umbrella species. We found a considerable geographic bias: most studies and, consequently, recommended umbrella species are from the Northern Hemisphere. There is also a strong taxonomic bias, with grouses (order Galliformes) and large carnivores being the most popular umbrella species and amphibians and reptiles being largely overlooked. In addition, wide-ranging and non-threatened species were frequently recommended as umbrella species. Given the observed biases and trends, we caution that appropriate species need to be chosen for each location, and it is important to confirm that popular, wide-ranging species are effective umbrella species. Moreover, amphibians and reptiles should be investigated for their potential as umbrella species. The umbrella-species strategy has many strengths and, if applied appropriately, may be one of the best options in today's conservation research and funding landscape.

Beaver pond identification from multi-temporal and multi- sourced remote sensing data

ABSTRACT The maintenance and restoration of wetland habitat is a priority conservation action for most waterfowl and other wetland-dependent species in North America. Despite much progress in targeting habitat management in staging and wintering areas, methods to identify and target high-quality breeding habitats that result in the greatest potential for wildlife are still required. This is particularly true for species that breed in remote, inaccessible areas such as the American black duck, an intensively managed game bird in Eastern North America. Although evidence suggests that black ducks prefer productive, nutrient-rich waterbodies, such as beaver ponds, information about the distribution and quality of these habitats across the vast boreal forest is lacking with accurate identification remaining a challenge. Continuing advancements in remote sensing technologies that provide spatially extensive and temporally repeated information are particularly useful in meeting this information gap. In this study, we used multi-source remotely sensed information and a fuzzy analytical hierarchy process to map the spatial distribution of beaver ponds in Ontario. The use of multi-source data, including a Digital Elevation Model, a Sentinel-2 Multi-Spectral Image, and RadarSat 2 Polarimetric data, enabled us to identify individual beaver ponds on the landscape. Our model correctly identified an average of 83.0% of the known beaver dams and 72.5% of the known beaver ponds based on validation with an independent dataset. This study demonstrates that remote sensing is an effective approach for identifying beaver-modified wetland features and can be applied to map these and other wetland habitat features of interest across large spatial extents. Furthermore, the systematic acquisition strategy of the remote sensors employed is well suited for monitoring changes in wetland conditions that affect the availability of habitats important to waterfowl and other wildlife.

Checklist and distribution of Galliform Birds (Order: Galliformes) in Iraq

A total of four genera and four species belong to one family, Phasianidae, Order Galliformes; about 72 specimens deposited in the bird's collection in the Iraq "Natural History Research Center and Museum INHM" were reviewed. In the current study, morphometrics of four species of taxidermy Galliform birds: Chukor Alectoris graeca (Meisner, 1804), Seesee Ammoperdix griseogularis (Brandt, 1843), Quail Coturnix coturnix (Linnaeus, 1758), and Black Partridge Francolinus francolinus (Linnaeus, 1766) were documented. In addition, the distribution ranges throughout Iraq and the Global Conservation Status of each mentioned species were reviewed and comprehensively discussed. The current study concluded that the collection of four species belongs to the Phasinidae Family of Galliformes Order, which deserved in INHM still abundance in the Iraqi environment; that Chukers Alectoris sp. more abundance in mountains and hills areas west and north of Iraq; While, Black partridge Francolinnus francolinus is more abundance in wetlands and Marshes south of Iraq. Global Conservation status listed them as Least Concern (LC). Keywords: Black partridge, Chukar, Galliform birds, Phasianidae, Quail.

Landscape characteristics and predation risk influence spatial variation in auditory courtship of an upland game bird

ContextNumerous wildlife species use a polygynous mating system, where males use auditory courtship behaviors to secure breeding opportunities. The acoustic adaptation hypothesis, risk reward, and landscape of fear theories suggest spatial variation in male auditory courtship will be influenced by areas in landscapes where sound transmission is increased, and predation risk is reduced. However, it is often unclear what landscape features drive spatial variation in courtship behaviors.ObjectivesWe quantified the influence of predation risk, land cover type, and resource selection on spatial trends in the auditory courtship behavior (gobbling activity) of Eastern wild turkeys (Meleagris gallopavo silvestris).MethodsWe used 53,025 gobbles coupled with GPS locations from 111 turkeys and 36 coyotes (Canis latrans), and distance metrics associated with hunter activity and land cover type, to investigate influences of predation risk, resource selection, and land cover type on spatial variation in gobbling activity in Georgia, USA.ResultsDistance to public access during hunting was the most influential predictor of gobbling activity, wherein the expected number of daily gobbles increased by 40% for every 500 m farther from public access. Daily gobbles decreased by 22% for every 500 m farther away from private property during hunting. We failed to find significant effects of land cover type and coyote use but found limited evidence that areas with increased predicted probability of turkey use was associated with increased gobbling.ConclusionsPredation risk associated with increased anthropogenic disturbance had the greatest influence on gobbling activity. Our findings suggest that altering hunter access by closing roads to vehicle use, reducing hunter activity, or creating refuge areas on the landscape could positively influence gobbling activity.
