Norovirus outbreak in a natural playground: A One Health approach.

Norovirus constitutes the most frequently identified infectious cause of disease outbreaks associated with untreated recreational water. When investigating outbreaks related to surface water, a One Health approach is insightful. Historically, there has been a focus on potential contamination of recreational water by bird droppings and a recent publication demonstrating human noroviruses in bird faeces suggested this should be investigated in future water‐related norovirus outbreaks. Here, we describe a One Health approach investigating a norovirus outbreak in a natural playground. On social media, a large amount of waterfowl were reported to defecate near these playground premises leading to speculations about their potential involvement. Surface water, as well as human and bird faecal specimens, was tested for human noroviruses. Norovirus was found to be the most likely cause of the outbreak but there was no evidence for transmission via waterfowl. Cases had become known on social media prior to notification to the public health service underscoring the potential of online media as an early warning system. In view of known risk factors, advice was given for future outbreak investigations and natural playground design.

An unusually large bird wing in mid-Cretaceous Burmese amber

All of the bird specimens previously recovered from Burmese amber have belonged to either immature specimens, or small-bodied taxa belonging to Enantiornithes. This has led to questions about whether the size bias inherent to preservation in amber has limited inclusions to smaller individuals or species, or if the avifauna of the amber-producing forest had a stronger representation of small-bodied taxa than other Cretaceous assemblages. A newly discovered inclusion of a fragmentary bird wing is described here: specimen LV-0321 likely belonged to an individual that was in excess of 10 cm long (snout to vent length). The new specimen also displays more prominent light-and-dark banding patterns among the primary flight feathers than any of the wings previously described from the deposit. In addition to increasing the known size range for enantiornithines within the assemblage, the new specimen sheds further light on the appearance of the plumage in these Cretaceous birds.

WILMOT W. BROWN: ONE OF THE MOST PROLIFIC COLLECTORS OF THE VERTEBRATE FAUNA OF THE NEW WORLD

Wilmot W. Brown (1870?–1953) collected birds, mammals, amphibians, and reptiles from 1890 until his death in 1953, amassing a collection that forms the core of knowledge of the distribution and taxonomy of the terrestrial vertebrate fauna of Central and South America. His collection of more than 18,000 bird specimens is spread over 25 institutions, although his longest collaboration was with Outram Bangs and John Thayer of the Museum of Comparative Zoology. He collected throughout the Caribbean; northern South America, including Colombia and Panama; and principally throughout Mexico, where he was based for more than 40 years, forming one of the most important collections ever amassed for that country. He collected more than 750 specimens now classified as some form of type specimen, and at least eight taxa are named in his honor, including two reptiles, a mammal, and five birds. Although he sent regular, detailed correspondence back to his benefactors in the United States, he never published a single professional article, and no field journal has been located, leaving his legacy obscured. In an era of lax data collection and fraudulent collectors, Brown's specimens and associated data have proven to be of high quality and help form the basis for our current understanding of New World biodiversity, although his legacy is marred by his disregard for the conservation plight of the species he collected.

Curation of the Historic England Zooarchaeology Reference Collection: Developing Strategies for Monitoring and Controlling Pests and Moulds

ABSTRACT The Historic England Zooarchaeology Reference Collection includes more than 3470 mammal, bird, amphibian, reptile and fish specimens, the majority of which are complete skeletons. It comprises important research collections that support internal, national and international projects, and is being continuously developed, mainly through in-house specimen preparation. The collection is housed in different locations at Fort Cumberland, an eighteenth-century military monument, and is therefore subject to varying environmental conditions, requiring tailored curation. This paper reports on an audit of the collection carried out in December 2016, in response to a perceived increase in the presence of insects, mould and grease, and the subsequent actions taken. The audit involved visual assessment and condition recording of each accessioned specimen. New specialist storage solutions were then implemented as part of the on-going collection curation, within the context of an integrated pest management strategy.

Diversifying Displays of Biological Sex and Sexual Behaviour in a Natural History Museum

Many natural history museums present species’ life histories in their galleries, which millions of visitors use to make meaning of the ‘natural world’ to which humans belong. Because curation is inherently practiced through a human’s perspective, and often the male gaze, images depicting the ‘natural world’ may be informed more by dominant understandings of sex and gender as social constructs of idealised bodies and behaviours than by scientific understanding. In this paper, we conduct a quantitative survey of displays in the Carnegie Museum of Natural History to test for biases that naturalise socially constructed gender ideals. We statistically tested for bias to display dioecious species (species where sex is partitioned into two bodies), to display male specimens, and to physically arrange taxidermy in ways that suggest females are coy and males are passionate. We find significant evidence of the invisibility of non-binary natural histories in noting that fewer than 10% of specimens on display are from monecious or non-binary species. Based on a survey of 392 mammal and bird specimens on display, there is a significant sex bias resulting in collections displaying one female specimen for every two male specimens. Moreover, the survey shows a significant bias in how a museum portrays female and male specimens, with 63% of 56 mixed-sex groups of mammals and birds physically arranged specimens in ways that suggested females are coy and males are passionate. Finally, we identify places where signage, programming, and interventions can be used as a starting point for a museum to tell more stories of non-binary biological sex, unfixed biological sex, same-sex sexual behaviour, and diverse family arrangements.

First report of Davaneidae and Strongylida parasitizing Ramphocelus carbo (Aves: Passeriformes: Thraupidae) in the southwest of the Brazilian Amazon region.

In Brazil, species of the genus Ramphocelus with the presence of various endoparasites have already been reported. Coccidia have been the parasites most frequently found. All species of this genus have similar habitats and ecological niches, which makes parasite transmission easy. The aim of this study was to diagnose the presence of endoparasites in fecal samples from specimens of Ramphocelus carbo that were caught in the Cazumbá-Iracema Extractive Reserve (Cazumbá Resex), in the State of Acre. The specimens (n = 30) were caught in mist nets arranged in different ecosystems of the Reserve. After identification, the bird specimens were placed in cloth bags for a maximum of 30 minutes to collect feces. Among the 22 samples collected, 63.63% (n = 14) were positive for endoparasites. The coccidia were the parasites most frequently. Helminths belonging to Ascaridiidae (Nematoda), Strongylida (Nematoda) and Davaneidae (Cestoda) were recorded for the first time in R. carbo in the State of Acre. Parasites belonging to Strongylida and Davaneidae were recorded for the first time in a species of Ramphocelus. These findings add information on the parasitic fauna of wild birds, since in the Amazon region there are few studies on this subject.

On birds of Santander-Bio Expeditions, quantifying the cost of collecting voucher specimens in Colombia

Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families. Such collection represents one of the largest series obtained during the historical ornithological exploration of Santander. We report differences among expeditions regarding the capture rate in mist nets, as well as differences in the sizes of taxa collected by mist nets and airgun. We discuss results in the context of previous ornithological expeditions in Colombia, commenting issues on the biology of some species, particularly those considered as noteworthy records (e.g., Red-legged Tinamou [Crypturellus erythropus], Cinnamon Screech Owl [Megascops petersoni], Saffron-headed Parrot [Pyrilia pyrilia], Black Inca [Coeligena prunellei], and Chestnut-crowned Gnateater [Conopophaga castaneiceps]). We calculated that the costs of obtaining and curating a specimen in Colombia, including tissues for molecular analysis, was ~US$60.4 (~$196 176 COP), which is among published costs of obtaining voucher specimens in other taxa and countries. These costs must be considered an investment in scientific capital because voucher specimens will provide biological information for hundreds of years.

Various Gallus varius hybrids: variation in junglefowl hybrids and Darwin's interest in them

Hybrids between Green Junglefowl Gallus varius and domestic fowl G. gallus domesticus confused several 19th-century ornithologists. The plumage of these hybrids is so unlike the colours and patterns of either of the parent species that they were considered to be distinct species: G. aeneusTemminck, 1825; G. temminckiiGray, 1849; and G. violaceusKelsall, 1891. Darwin wanted to understand if G. aeneus and G. temminckii were hybrids or species, as part of his research on the origin of the domestic chicken. His view was that all domesticated fowl have a single wild ancestor, Red Junglefowl G. gallus (formerly G. bankiva). A hybrid specimen now present in the bird collection of the Natural History Museum at Tring played an important role in Darwin's reasoning and, although the conclusions he drew from this specimen were incorrect, his single-ancestor origin theory for domesticated fowl stands.‘These hybrids were at one time thought to be specifically distinct, and were named G. aeneus. Mr. Blyth and others believe that the G. Temminckii is a similar hybrid' (Darwin 1868a: 234–235).

Survey and Characterization of Jingmen Tick Virus Variants.

We obtained a Jingmen tick virus (JMTV) isolate, following inoculation of a tick pool with detectable Crimean-Congo hemorrhagic fever virus (CCHFV) RNA. We subsequently screened 7223 ticks, representing 15 species in five genera, collected from various regions in Anatolia and eastern Thrace, Turkey. Moreover, we tested specimens from various patient cohorts (n = 103), and canine (n = 60), bovine (n = 20) and avian specimens (n = 65). JMTV nucleic acids were detected in 3.9% of the tick pools, including those from several tick species from the genera Rhipicephalus and Haemaphysalis, and Hyalomma marginatum, the main vector of CCHFV in Turkey. Phylogenetic analysis supported two separate clades, independent of host or location, suggesting ubiquitous distribution in ticks. JMTV was not recovered from any human, animal or bird specimens tested. Near-complete viral genomes were sequenced from the prototype isolate and from three infected tick pools. Genome topology and functional organization were identical to the members of Jingmen group viruses. Phylogenetic reconstruction of individual viral genome segments and functional elements further supported the close relationship of the strains from Kosovo. We further identified probable recombination events in the JMTV genome, involving closely-related strains from Anatolia or China.

Sex biases in bird and mammal natural history collections.

Natural history specimens are widely used across ecology, evolutionary biology and conservation. Although biological sex may influence all of these areas, it is often overlooked in large-scale studies using museum specimens. If collections are biased towards one sex, studies may not be representative of the species. Here, we investigate sex ratios in over two million bird and mammal specimen records from five large international museums. We found a slight bias towards males in birds (40% females) and mammals (48% females), but this varied among orders. The proportion of female specimens has not significantly changed in 130 years, but has decreased in species with showy male traits like colourful plumage and horns. Body size had little effect. Male bias was strongest in name-bearing types; only 27% of bird and 39% of mammal types were female. These results imply that previous studies may be impacted by undetected male bias, and vigilance is required when using specimen data, collecting new specimens and designating types.

Feather mites (Acari: Astigmata) of the Zoobotanical State Park in Teresina, Brazil

Feather mites are the most diverse avian ectoparasites. They mainly live on the plumage of birds, feeding on uropygial oil, and may occasionally cause skin irritation, especially on caged birds. Here we report the results of a survey of feather mites on wild birds of the Zoobotanical State Park of Teresina, Piauí, Brazil. The following mites were collected from seven bird specimens kept in the park from January to July 2017: Pandionacarus fuscus (Nitzsch, 1818) on the osprey (Pandion haliaetus); Freyana dendrocygni Dubinin, 1950 and Heterobrephosceles megathrix Peterson and Atyeo, 1977 on the white-faced whistling-duc (Dendrocygna viduata); Nyctibiolichus megamerus Atyeo, 1979 on the common potoo (Nyctibius griseus); Hieracolichus hirundo (Mégnin and Trouessart, 1884) on the harpy eagle (Harpia harpyja) and Hieracolichus sp. on the southern caracara (Caracara plancus). These findings increase the known ranges of the mite species, with four of them reported for the first time in Brazil.

Feathers and food: Human-bird interactions at Middle Pleistocene Qesem Cave, Israel

The presence of fast-moving small game in the Paleolithic archaeological faunal record has long been considered a key variable to assess fundamental aspects of human behavior and subsistence. Birds occupy a prominent place in this debate not only due to their small size and to the difficulties in capturing them (essentially due to their ability to fly and their elusiveness), but also due to their possible role in the symbolic array in regard to non-nutritional elements (feathers, talons, etc.) and as reflectors of complex human–world relationships. In this study, we attempt to contribute to this topic by presenting taphonomical data of bird specimens from Qesem Cave (Israel), dated between 420 and 200 ka. Human-induced damage, including cut marks, peeling and human gnawing, has been identified on wing bones of Cygnus sp., Columba sp., Corvus ruficollis and Sturnus sp. Our evidence suggests that avian exploitation was not limited to food only—either to complement the human diet or as occasional food item—but also presumably for the use of feathers. While the consumption of birds as a dietary source seems to be evident as early as the Early Pleistocene, the non-alimentary use of inedible elements, such as feathers and talons, appears to be a practice from the Middle Paleolithic onwards. We argue that the combined nutritional and symbolic use of birds is one characteristic of the new mode of adaptation practiced already by the late Lower Paleolithic Acheulo-Yabrudian hominins in the Levant starting 400 ka. The Qesem findings point to the possible emergence of new cognitive and behavioral skills, which are followed in later periods in the Old World. Finally, we discuss the possible ontological and cosmological significance of human–bird interactions to illuminate our hypothesis regarding the emergence of a new perception of human relationships with the world as an integral part of the new Acheulo-Yabrudian mode of adaptation.

High prevalence and diversity of extended-spectrum β-lactamase and emergence of OXA-48 producing Enterobacterales in wildlife in Catalonia.

Most of the studies focused on antimicrobial resistance (AMR) performed in wildlife describe Escherichia coli as the principal indicator of the selective pressure. In the present study, several species of Enterobacterales with a large panel of cephalosporin resistant (CR) genes have been isolated from wildlife in Catalonia. A total of 307 wild animals were examined to determine the prevalence of CR enterobacteria, AMR phenotypes and the presence of common carbapenem and CR genes. The overall prevalence of CR-phenotype was 13% (40/307): 17.3% in wild mammals (18/104) and 11.5% in wild birds (22/191) (p<0.01). Hedgehogs showed the highest prevalence (13.5% of 104) of the mammal specimens, and raptors the highest in bird specimen (7.3% of 191). Although CR E. coli was the most frequently isolated (45%), other CR- Enterobacterales like Klebsiella pneumoniae (20%), Citrobacter freundii (15%), Enterobacter cloacae (5%), Proteus mirabilis (5%), Providencia spp (5%) and Serratia marcescens (2.5%) were also isolated. A high diversity of CR genes was identified among the isolates, with 50% yielding blaCMY-2, 23% blaSHV-12, 20% blaCMY-1 and 18% blaCTX-M-15. Additionally, resistance to carbapenems associated to OXA-48 gene was found. Most of the CR isolates, principally K. pneumoniae and C. freundii, were multi-resistant with co-resistance to fluoroquinolones, tetracycline, sulphonamides and aminoglycosides. This study reports high prevalence of Enterobacterales harbouring a variety of CR genes and OXA-48 mediated-carbapenem resistance, all of them frequently associated to nosocomial human infections, for the first time in wild mammals and wild birds. Implementation of control measures to reduce the impact of anthropogenic pressure in the environment is urgently needed.

Migration flyways of geese in Central Siberia

Observations of geese abundance and migration in Central Siberia are especially relevant for international scientists due to the lack of objective data on this topic in English literature. The goal of this paper is to summarize the results of a long-term study (1980-2016) on migration of geese in Central Siberia, to distinguish and describe their migration routes in the environment of Continental Asia. The authors used a methodological complex comprising universally accepted techniques of ornithological studies, such as visual and instrumental observations at staging sites and along geese migration routes, registration of birds on the ground (travelling on foot, by boat or by car) and in the air (using aircraft). To clarify the subspecies, the authors carried out collection of birds or their body parts (heads, wings, legs, n = 1032 units). Capture and banding of nesting geese was done in the Altai-Sayan Ecoregion. The places and dates of maximum geese concentration, as well as the time of their departure, are quite permanent; that made it possible to carry out their definite registration using aircraft (25.5 thousand km). The works at each of the most significant sites were performed annually, at the same time of the year. They also analyzed data available in scientific literature and reports on returns of rings from the Ringing Center of the Russian Academy of Sciences, as well as information about geese received from hunters and specialists of environmental services. The paper shows main migration routes and their territorial connections. The Great Lakes Depression in Mongolia is a kind of “migration dead end” for a great number of waterfowl migrating in spring.

A New Enantiornithine Bird with Unusual Pedal Proportions Found in Amber

Recent discoveries of vertebrate remains trapped in middle Cretaceous amber from northern Myanmar [1, 2] have provided insights into the morphology of soft-tissue structures in extinct animals [3-7], in particular, into the evolution and paleobiology of early birds [4, 8, 9]. So far, five bird specimens have been described from Burmese amber: two isolated wings, an isolated foot with wing fragment, and two partial skeletons [4, 8-10]. Most of these specimens contain the remains of juvenile enantiornithine birds [4]. Here, we describe a new specimen of enantiornithine bird in amber, collected at the Angbamo locality in the Hukawng Valley. The new specimen includes a partial right hindlimb and remiges from an adult or subadult bird. Its foot, of which the third digit is much longer than the second and fourth digits, is distinct from those of all other currently recognized Mesozoic and extant birds. Based on the autapomorphic foot morphology, we erect a new taxon, Elektorornis chenguangi gen. et sp. nov. We suggest that the elongated third digit was employed in a unique foraging strategy, highlighting the bizarre morphospace in which early birds operated.

Adding value to collections: improving the data associated with Crested Ibis Nipponia nippon specimens held in the Natural History Museum, Tring

In the bird collection of the Natural History Museum at Tring (NHMUK), and no doubt in many analogous collections elsewhere, older specimens are increasingly likely to have become divorced from some, or even all, of the data that once accompanied them. As the utility of such specimens for research depends in large part on their accompanying data, it is important, though time-consuming, to try to restore missing data to them. Stimulated by a genomic research project request to sample all Crested Ibis Nipponia nippon specimens in the NHMUK collection, this paper presents a case study of such an attempt. The results are used to highlight the importance that such investigation is factored into projects aiming to make museum specimen data available online.

Analisis Dimorfisme Kupu-Kupu Sayap Burung (Ornithoptera sp.) Endemik Papua

Ornitophera sp. is one of the groups of butterflies endemic in Papua and West Papua provinces. The significant morphological differences between male and female butterflies (dimorphism) are in the shape, size and color of the wings. Morphological characteristics are important sources of information. Based on the results of specimen collections at the Papua Insect Collection Laboratory (KSP) Jayapura, there are several species from various locations in Papua. The variation in dimorphism is likely to occur in this species which gives rise to new sub-species. The purpose of this study was to record the dimorphism of the endemic Bird Wing of Papua which had been stored in the Papua Insect Collection Laboratory (KSP) Jayapura. The method used is a direct measurement of the morphology of bird wing butterfly specimens stored in the KSP Laboratory, Cenderawasih University. Morphometric data were analyzed using the SPSS 20 and Multi Variate Statistical Package (MVSP 3.1) programs. The results obtained were 7 Ornithoptera species stored in the KSP Jayapura Laboratory, namely O. chiamera, O. goliath, O. meridionalis, O. paradisea, O. priamus, O. thitonus and O. rothschildi. Based on observations there are striking differences in color, shape and size between male and female in the same species.   Key words: birdwing butterfly, Ornithoptera sp., KSP Jayapura, dimorphisme. Â

Avian mitochondrial genomes retrieved from museum eggshell

Avian eggshell is a bio-ceramic material with exceptional properties for preserving DNA within its crystalline structure, presenting an opportunity to retrieve genomic information from extinct or historical populations of birds. However, intracrystalline DNA has only been recovered from the large, thick eggshell of palaeognaths; members of their more-diverse sister group (neognaths) lay smaller, thinner eggs that may not exhibit the same propensity for DNA preservation. Here, we use three 40-60-year-old museum eggshell specimens of Australian neognath birds to determine the minimum mass of eggshell from which intracrystalline DNA can be retrieved, and to characterize the yield and quality of such DNA. In doing so, we describe the first protocol for successful extraction of intracrystalline DNA from neognath eggshells, with the view to unlocking the potential of vast museum egg collections for genetic research. We were able to retrieve DNA fragments over 200bp in length from 10mg of eggshell powder from all three specimens, and demonstrate that expanding the existing blow-hole can allow sufficient material to be collected for DNA extraction while minimizing damage to the appearance and structural integrity of the egg. Furthermore, we were able to reconstruct near-complete mitochondrial genomes at a coverage of 40-83X through shotgun sequencing of these extracts on three NextSeq lanes. Given the current extinction and extirpation rates of many avian species world-wide, genetic data from eggshell could provide a rapid and cost-effective approach to examining temporal changes in avian diversity, which is not only becoming crucial for conservation management, but also serve to deepen our understanding of genome-wide evolutionary processes.
