Ring-necked pheasant (Phasianus colchicus; i.e., pheasant) hunting participation is declining across North America, reflecting a larger downward trend in American hunting participation and threatening benefits to grassland conservation and rural economies. To stabilize and expand the pheasant hunting population, we must first identify factors that influence pheasant hunter participation. We used an extensive in-person hunter survey to test the hypothesis that hunter demographics interact with social-ecological traits of hunting locations to affect hunter decisions, outcomes, and perceptions. We built a series of Bayesian mixed effects models to parse variation in demographics, perceptions, and hunt outcomes of pheasant hunters interviewed at public access hunting sites across 3 regions in Nebraska, USA, that varied in pheasant abundance and proximity to urban population centers. Among pheasant hunters in Nebraska, access to private lands was negatively related to the human population density of a pheasant hunter’s home ZIP code and the distance a hunter had traveled to reach a hunting location. Pheasant hunters interviewed closer to metropolitan areas tended to be more urban and travel shorter distances, and their parties were more likely to include youth but less likely to include dogs. Hunter satisfaction was positively associated with seeing and harvesting pheasants and hunting with youth. Whereas youth participation and the number of pheasants seen varied by study region, hunter satisfaction did not differ across regions, suggesting that hunters may calibrate their expectations and build their parties based on where they plan to hunt. The variation in hunter demographics across hunting locations and disconnects between social and ecological correlates of hunter satisfaction suggests that diverse pheasant hunting constituencies will be best served by diverse pheasant hunting opportunities.

Understanding predator-prey coexistence mechanisms is essential for conserving endemic species in montane ecosystems. Galliformes serve as critical ecological indicator species, yet their populations are declining globally due to habitat fragmentation and anthropogenic pressures. Elliot’s pheasant (Syrmaticus ellioti , Swinhoe, 1872), a Galliformes species endemic to China, is primarily distributed south of the Yangtze River. However, its coexistence mechanisms with sympatric predators remain undocumented. Here, using six years (2019–2024) of camera-trap data from 90 stations in Jiemuxi National Nature Reserve, Hunan Province, Southwest China, we employed a MaxEnt model and kernel density estimation to investigate spatiotemporal coexistence mechanisms between Elliot’s pheasant and its primary predator, the leopard cat (Prionailurus bengalensis , Kerr, 1792). Across 36,946 camera-days, we obtained 227 independent detections of Elliot’s pheasant and 82 of the leopard cat. Spatial niche analysis revealed high overlap (Schoener’s D = 0.769; Hellinger’s I = 0.952). Both species exhibit similar preferences for main environmental variables. Conversely, significant temporal niche segregation occurred: Elliot’s pheasant displayed diurnal bimodal activity, whereas the leopard cat was strictly nocturnal, resulting in low overlap (Δ[sub.4] = 0.379, p < 0.01). Critically, during Elliot’s pheasant’s breeding season, increased temporal overlap with the leopard cat (Δ[sub.1] = 0.479, p < 0.01) suggested that reproductive behaviors elevate predation risk. Our findings demonstrate that temporal niche partitioning serves as the primary coexistence mechanism, while spatial niche overlap and behavioral adaptations under predation pressure drive dynamic predator-prey interactions. This provides a scientific foundation for targeted conservation strategies and predator management of these threatened Galliformes.

Since the introduction of the Golden Pheasant (Chrysolophus pictus)to Haleakala volcano, Maui, three decades ago, subsequent reports have hinted at an expansion of this nascent population. We draw from a variety of data sources to learn about this pheasant's present status on Maui. First, forest bird surveys conducted every five years revealed that the frequency of Golden Pheasant detections has greatly increased, and the bird has both maintained its former distribution and expanded eastward into Haleakala National Park (NP). Second, reports to eBird from The Nature Conservancy's Waikamoi Preserve, where Golden Pheasants first appeared on Maui, demonstrate that the frequency of observations has increased and is strongly seasonal, predominantly in the spring. Third, autonomous recording units monitoring endangered forest birds recorded pheasants too, adding new locations. Finally, trail cameras set to monitor mammals picked up pheasants as well, showing males of two color morphs: original \"wild-type\" and \"dark-throated.\" Trail cameras also documented a small juvenile at Waikamoi Preserve and both females and males in Haleakala NP. By \"connecting the dots\" of mapped occurrences, we traced the pheasant's progression through a narrow band of subalpine cloud forest with open understory, extending from Waikamoi Preserve eastward to upper Kipahulu Valley, a distance of 14 km. In summary, this body of evidence supports the claim that the Golden Pheasant has established a self-sustaining population on Maui, and we propose that the species' success there may be attributed to the minimal influence of predators and the absence of competing gallinaceous birds in its preferred habitat.

Captive breeding programs are crucial to ensure the survival of endangered species and ultimately to reintroduce individuals into the wild. However, captive-bred populations can also deteriorate due to inbreeding depression and reduction of genetic variability. We genotyped a captive population of 82 individuals of the endangered Hume's pheasant (Syrmaticus humiae, Hume 1881) at the Doi Tung Wildlife Breeding Center to assess the genetic consequences associated with captive breeding. Analysis of microsatellite loci and mitochondrial D-loop sequences reveal significantly reduced genetic differentiation and a shallow population structure. Despite the low genetic variability, no bottleneck was observed but 12 microsatellite loci were informative in reflecting probable inbreeding. These findings provide a valuable source of knowledge to maximize genetic variability and enhance the success of future conservation plans for captive and wild populations of Hume's pheasant.

Infectious diseases in captive pheasants (Phasianus colchicus) are well known, but there is a lack of knowledge about occurrence and distribution of pathogens in free-ranging pheasants in Germany. We investigated 604 sera from hunted pheasants and 152 sera from wild caught pheasants between 2011 to 2015, with the aim to determine the prevalence of specific antibodies against different viruses: Avian influenza virus (AIV) of subtypes H5, H7, H9, paramyxovirus type 1 (PMV-1), avian encephalomyelitis virus (AEV), infectious bursitis disease virus (IBDV), infectious bronchitis virus (IBV), infectious laryngotracheitis virus (ILTV), avian metapneumovirus (aMPV) and Salmonella sp., Mycoplasma synoviae (MS) and Mycoplasma gallisepticum (MG). In addition, 178 caeca were investigated for Histomonas meleagridis. The study reveals an ongoing circulation of IBV in the wild pheasant population during the study. Also high seroprevalences of specific antibodies against aMPV depending on the area and a strong increase in prevalence of IBDV antibodies in sera of pheasants in Lower Saxony were detected. ILTV antibody prevalences differed between areas and AEV antibody detection differed between years significantly, whereas specific antibodies against PMV-1 could not be detected and antibodies against AIV-H5, -H7 and -H9 and Mycoplasma spp. were detected in very few cases.

Lead concentrations in commercial dogfood containing pheasant in the UK
2023
UK and EU regulators are evaluating the potential health benefits of restricting the use of lead ammunition. Little information is available on exposure of pets to ammunition-derived dietary lead from petfood containing meat from wild-shot game animals. We found dogfood including wild-shot pheasant meat to be widely available in the UK. 77% of samples from three raw pheasant dogfood products exceeded the EU maximum residue level (MRL) for lead in animal feed, with mean concentrations approximately 245, 135 and 49 times above the MRL. Concentrations > MRL were also found in a dried food containing pheasant, but not in a processed food, nor in chicken-based products. Lead concentrations in raw pheasant dogfood considerably exceeded those in pheasant meat sold for human consumption, possibly because the dogfood mincing process further fragmented lead particles from shot. Dogs frequently consuming such high-lead food risk adverse health effects; this should be considered within decision-making processes about regulation.

Decrease in Hatchability of Pheasant Eggs Associated with Enterococcus faecalis
2020
A game bird producer in the North Central region of the United States submitted unhatched ring-neck pheasant (Phasianus colchicus) eggs for diagnostic evaluation. The submitting complaint was a drastic drop in hatchability. This operation has its own breeder birds that are housed in outside pens. This hatch occurred in the latter third of the production cycle. Typical hatchability for this operation is around 75% (± 3%). The hatchability of this hatch was between 14%–15%. Approximately 30,000 eggs were set with an expected hatchability of about 23,000 birds. The number of birds from this hatch was less than 4500, with a net loss approaching 20,000 chicks. All unhatched eggs submitted were in late stage development. The chick embryos had pipped through the shell but died before hatching. Approximately 5000 eggs originating from an outside breeder source were also set at the same time in the same machines and experienced a normal hatch. The exterior surfaces of the eggshells of the unhatched eggs experiencing low hatchability were swabbed and submitted for bacteriologic evaluation. Additionally, embryos from some of the unhatched eggs were removed aseptically from their eggshells, and their internal organs were harvested and submitted for bacteriologic evaluation. The bacteriology results identified no pathogenic bacteria from the eggshells. However, the embryo samples revealed large quantities of Enterococcus faecalis. In discussions with the producer, the only factor identified was an unusually warm period followed by an atypically cold and wet period during the time of egg collection for those eggs experiencing low hatchability.

The ‘pheasant of the future’: Encountering and imagining Reeves’ pheasant in Britain, 1831 – 1913
2024
This paper examines the presence of Reeves’ pheasant ( Syrmaticus reevesii ) in Britain. It investigates how encounters between British people and Reeves’ pheasant informed their imaginings of the species, from its first introduction into Britain from China in 1831 to 1913 when a serious decline in its numbers began. Drawing on natural history texts, records from the Proceedings of the Zoological Society of London , technical literature on pheasant rearing, and extracts from periodicals, magazines, and generalist encyclopaedias, this paper shows how imagined and physical encounters with Reeves’ pheasant, by naturalists, acclimatisers, pheasant enthusiasts, and sportsmen, informed shifting constructions of the species, which influenced and shaped its presence in Britain.

Habitat suitability assessment for the Near Threatened Hume's Pheasant (Syrmaticus humiae) in a new distribution location in southwestern China
2022
We discovered a population of the Near Threatened Hume's Pheasant (Syrmaticus humiae) in the Ziyun County of Anshun City in 2016. Land and forestry administrators jointly proposed establishing a nature reserve for the conservation of this population. We conducted surveys and a habitat suitability assessment of this pheasant in support of the conservation strategy planning and proposed nature reserve. Our results suggest that this pheasant uses heavily disturbed, open canopy, broad-leaved forests at a certain distance to roads on northwest- to north-facing slopes. It also uses sparse canopy forests on moderate to steep slopes below elevations of 1,050 m near water. The use of heavily disturbed, open canopy forests of this pheasant population is not consistent with reports from the literature. This could be a response of this population to available disturbed habitat. This population may be part of an undiscovered population of the wildlife management units of Guangxi and Guizhou. Understanding habitat requirements of this species warrants further investigations, e.g., genetic tests such as sequencing of mitochondrial DNA to compare with other populations and assessment of its population status, patterns of habitat use, and interactions with heavily disturbed habitats.
