Abstract
Two novel reassortant highly pathogenic avian influenza viruses (H5N1) clade 2.3.4.4b.2 were identified in dead migratory birds in China in November 2021. The viruses probably evolved among wild birds through different flyways connecting Europe and Asia. Their low antigenic reaction to vaccine antiserum indicates high risks to poultry and to public health.

Abstract
This study aimed to evaluate antimicrobial resistance, virulence, and the genetic diversity of Aeromonas isolated from migratory birds from Guangxi Province, Guangdong Province, Ningxia Hui Autonomous Region, Jiangxi Province, and Inner Mongolia in China. A total of 810 samples were collected, including fresh feces, cloacal swabs, and throat swabs. The collected samples were processed and subjected to bacteriological examination. The resistance to 21 antibiotics was evaluated. A phylogenetic tree was constructed using concatenated gltA-groL-gyrB-metG-PPSA-recA sequences. Eight putative virulence factors were identified by PCR and sequencing, and a biofilm formation assay was performed using a modified microtiter plate method. In total, 176 Aeromonas isolates were isolated including A. sobria, A. hydrophila, A. veronii, and A. caviae. All isolates showed variable resistance against all 16 tested antibiotic discs, and only one antibiotic had no reference standard. Six kinds of virulence gene markers were discovered, and the detection rates were 46.0% (hlyA), 76.1% (aerA), 52.3% (alt), 4.5% (ast), 54.0% (fla), and 64.2% (lip). These strains were able to form biofilms with distinct magnitudes; 102 were weakly adherent, 14 were moderately adherent, 60 were non-adherent, and none were strongly adherent. Our results suggest that migratory birds carry highly virulent and multidrug-resistant Aeromonas and spread them around the world through migration, which is a potential threat to public health.

Abstract
The Asian longhorned tick (Haemaphysalis longicornis Neumann), native to East Asia, was first reported in the United States in 2017 and is now established in at least 17 states. Haemaphysalis longicornis feeds on birds in its range outside of the United States, and migratory birds disperse this tick and tick-borne pathogens. However, early studies in the United States did not find H. longicornis on migrating passerine birds. The transport of the parthenogenetic H. longicornis on birds has the potential to greatly expand its range. We report the first discovery of H. longicornis on migratory passerine birds in the Americas.

Abstract
A recent study demonstrated the possibility that migratory birds are responsible for the global spread of avian rotavirus A (RVA). However, little is known about what types of RVAs are retained in migratory birds. In this study, to obtain information on RVA strains in migratory birds, we characterised an RVA strain, Ho374, that was detected in a faecal sample from a gull species (Larus sp.). Genetic analysis revealed that all 11 genes of this strain were classified as new genotypes (G28-P[39]-I21-R14-C14-M13-A24-N14-T16-E21-H16). This clearly indicates that the genetic diversity of avian RVAs is greater than previously recognised. Our findings highlight the need for investigations of RVA strains retained in migratory birds, including gulls.

Abstract
Avian G18P[17] rotaviruses with similar complete genome constellation, including strains that showed pathogenicity in mammals, have been detected worldwide. However, it remains unclear how these strains spread geographically. In this study, to investigate the role of migratory birds in the dispersion of avian rotaviruses, we analysed whole genetic characters of the rotavirus strain RK1 that was isolated from a migratory species of birds [velvet scoter (Melanitta fusca)] in Japan in 1989. Genetic analyses revealed that the genotype constellation of the RK1 strain, G18-P[17]-I4-R4-C4-M4-A21-N4-T4-E4-H4, was highly consistent with those of other G18P[17] strains detected in various parts of the world, supporting the possibility that the G18P[17] strains spread via migratory birds that move over a wide area. Furthermore, the RK1 strain induced diarrhoea in suckling mice after oral gastric inoculation, indicating that at least some of the rotaviruses that originated from migratory birds are infectious to and pathogenic in mammals. In conclusion, it was demonstrated that migratory birds may contribute to the global spread of avian rotaviruses that are pathogenic in mammalian species.

Abstract
One possible hypothesis for the function of post-fledging dispersal is to locate a suitable future breeding area. This post-fledging period may be particularly important in migratory species because they have a limited period to gather information prior to autumn migration, and in protandrous species, males must quickly acquire a territory after returning from spring migration to maximize their fitness. Here we use color-ring resightings to investigate how the post-fledging dispersal movements of the Cyprus wheatear Oenanthe cypriaca, a small migratory passerine, relate to their first breeding territory the following year when they return from migration. We found that males established first breeding territories that were significantly closer to their post-fledging location than to their natal sites or to post-fledging locations of other conspecifics, but these patterns were not apparent in females. Our findings suggest that familiarity with potential breeding sites may be important for juveniles of migratory species, particularly for the sex that acquires and advertises breeding territories. Exploratory dispersal prior to a migrant's first autumn migration may contribute toward its breeding success the following year, further highlighting the importance of early seasonal breeding on fitness and population dynamics more generally.

Abstract
Eastern equine encephalitis virus (EEEV; family Togaviridae, genus Alphavirus) is a mosquito-borne pathogen found in eastern North America that causes severe disease in humans and horses. The mosquito Culiseta melanura (Coquillett) (Diptera: Culicidae) is the primary enzootic vector of EEEV throughout eastern North America while several mosquito species belonging to diverse genera serve as bridge vectors. The ecology of EEEV differs between northern and southern foci, with respect to phenology of outbreaks, important vertebrate hosts, and bridge vector species. Active transmission is limited to roughly half of the year in northern foci (New York, New Hampshire, Massachusetts, Connecticut), while year-round transmission occurs in the southeastern region (particularly Florida). Multiple phylogenetic analyses indicate that EEEV strains circulating in northern foci are likely transported from southern foci by migrating birds. Bird species that overwinter or migrate through Florida, are bitten by Cs. melanura in late spring, and arrive at northern breeding grounds in May are the most likely candidates to disperse EEEV northward. Available data indicate that common yellowthroat and green heron satisfy these criteria and could serve as virus dispersers. Understanding the factors that drive the phenology of Cs. melanura reproduction in the south and the timing of avian migration from southern foci could provide insight into how confluence of these biological phenomena shapes outbreaks of EEE throughout its range. This information could be used to develop models predicting the likelihood of outbreaks in a given year, allowing vector control districts to more efficiently marshal resources necessary to protect their stakeholders.

Abstract
The past two decades have seen the emergence of highly pathogenic avian influenza (HPAI) infections that are characterized as extremely contagious, with a high fatality rate in chickens, and humans; this has sparked considerable concerns for global health. Generally, the new variant of the HPAI virus crossed into various countries through wild bird migration, and persisted in the local environment through the interactions between wild and farmed birds. Nevertheless, no studies have found informative cases associated with connecting local persistence and long-range dispersal. During the 2016–2017 HPAI H5N6 epidemic in South Korea, we observed several waterfowls with avian influenza infection under telemetric monitoring. Based on the telemetry records and surveillance data, we conducted a case study to test hypotheses related to the transmission pathway between wild birds and poultry. One sedentary wildfowl naturally infected with HPAI H5N6, which overlapped with the home range of one migratory bird with H5-specific antibody-positive, showed itself to be phylogenetically close to the isolates from a chicken farm located within its habitat. Our study is the first observational study that provides scientific evidence supporting the hypothesis that the HPAI spillover into poultry farms is caused by local persistence in sedentary birds, in addition to its long-range dispersal by sympatric migratory birds.

Abstract
Large highly pathogenic avian influenza (HPAI) outbreaks caused by clade 2.3.4.4e H5N6
viruses occurred in Japan during the 2016–2017 winter. To date, several reports regarding
these outbreaks have been published, however a comprehensive study including geographical
and time course validations has not been performed. Herein, 58 Japanese HPAI virus (HPAIV)
isolates from the 2016–2017 season were added for phylogenetic analyses and the antigenic
relationships among the causal viruses were elucidated. The locations where HPAIVs were
found in the early phase of the outbreaks were clustered into three regions. Genotypes C1,
C5, and C6–8 HPAIVs were found in specific areas. Two strains had phylogenetically
distinct hemagglutinin (HA) and non-structural (NS) genes from other previously identified
strains, respectively. The estimated latest divergence date between the viral genotypes
suggests that genetic reassortment occurred in bird populations before their winter
migration to Japan. Antigenic differences in 2016–2017 HPAIVs were not observed,
suggesting that antibody pressure in the birds did not contribute to the selection of
HPAIV genotypes. In the late phase, the majority of HPAI cases in wild birds occurred
south of the lake freezing line. At the end of the outbreak, HPAI re-occurred in East
coast region, which may be due to the spring migration route of Anas bird
species. These trends were similar to those observed in the 2010–2011 outbreaks,
suggesting there is a typical pattern of seeding and dissemination of HPAIV in Japan.

Abstract
The spread of antimicrobial-resistant bacteria (ARB) in natural environments including wild animals is a concern for public health. Birds cover large areas, and some fly across borders to migrate in large flocks. As a migratory bird, the Greater White-fronted Goose (Anser albifrons) travels to Miyajimanuma, North Japan, each spring and autumn. To investigate the ARB in migratory birds and their surroundings, we collected 110 fecal samples of A. albifrons and 18 water samples from Miyajimanuma in spring and autumn of 2019. Isolation of Escherichia coli was performed using selective agars with or without antimicrobials (cefazolin and nalidixic acid). Isolates of E. coli were recovered from 56 fecal samples (50.9%) and five water samples (27.8%) on agars without antimicrobials. No isolates were recovered on agars with antimicrobials. One E. coli isolate derived from a fecal sample exhibited resistance to β-lactams (ampicillin and cefazolin), whereas all other isolates exhibited susceptibility to all tested antimicrobials. The resistant isolate harbored blaACC, which could be transferred to other bacteria and confer resistance to β-lactams. These results suggest a low prevalence of antimicrobial resistance in wild migratory birds and their living environments; however, wild migratory birds sometimes carry ARB harboring transferrable antimicrobial resistance genes and therefore present a risk of spreading antimicrobial resistance.

Abstract
Phenological shifts may ameliorate negative effects of climate change or create carryover effects and mismatches that decrease fitness. Identifying how phenological shifts affect performance is critical for understanding how individuals and populations will respond to climate change, but requires long-term, longitudinal data. Using 34 yr of data from the Magellanic penguin (Spheniscus magellanicus) colony at Punta Tombo, Argentina, we examined the consequences of the delayed onset of breeding (i.e., arrival and egg-laying dates) that has occurred at the colony since 1983. To understand how the delay propagates through the rest of the reproductive cycle, we identified phenological trends in hatch and fledge dates. Median hatch dates were 0.29 d later each year, amounting to a 10-d shift over the course of the study. Median fledge dates did not shift over the 34-yr period, however, thus shortening the median nestling period duration by 14%. We tested several predictions regarding performance outcomes of the compressed nestling period, finding that later-hatched chicks fledged significantly younger than earlier-hatched chicks, and that younger fledglings left the colony with smaller bills and with more chick down. Interestingly, although younger chicks fledged significantly lighter and in worse body condition than older fledglings early in the study, this trend reversed over time, with younger chicks actually fledging heavier and in better body condition in more recent years. Smaller and lighter fledglings were less likely to recruit to the colony as adults. We find that delayed breeding has significantly compressed nestling periods at Punta Tombo, influencing chick growth and fledgling condition. These findings highlight the importance of studying phenology across multiple life events to understand the consequences of phenological shifts for organismal fitness.

Abstract
Migratory birds are recently recognized as Vibrio disease vectors, but may be widespread transporters of Vibrio strains. We isolated Vibrio cholerae (V. cholerae) and Vibrio metschnikovii (V. metschnikovii) strains from migratory bird epidemic samples from 2017 to 2018 and isolated V. metschnikovii from migratory bird feces in 2019 from bird samples taken from the Inner Mongolia autonomous region of China. To investigate the evolution of these two Vibrio species, we sequenced the genomes of 40 V. cholerae strains and 34 V. metschnikovii strains isolated from the bird samples and compared these genomes with reference strain genomes. The pan-genome of all V. cholerae and V. metschnikovii genomes was large, with strains exhibiting considerable individual differences. A total of 2,130 and 1,352 core genes were identified in the V. cholerae and V. metschnikovii genomes, respectively, while dispensable genes accounted for 16,180 and 9,178 of all genes for the two strains, respectively. All V. cholerae strains isolated from the migratory birds that encoded T6SS and hlyA were non-O1/O139 serotypes without the ability to produce CTX. These strains also lacked the ability to produce the TCP fimbriae nor the extracellular matrix protein RbmA and could not metabolize trimetlylamine oxide (TMAO). Thus, these characteristics render them unlikely to be pandemic-inducing strains. However, a V. metschnikovii isolate encoding the complete T6SS system was isolated for the first time. These data provide new molecular insights into the diversity of V. cholerae and V. metschnikovii isolates recovered from migratory birds.

Abstract
The use of pesticides is associated with the decline of several avian species. In this study, we monitored the organochlorine contaminants in common swifts (Apus apus) in the years 2016 to 2018. These long-distance migrants breed in Europe and winter in Africa. Their only feeding source is aerial plankton. Pooled organ samples of 42 adult and 40 juvenile swifts were tested with the multi-residue method by gas chromatography-mass spectrometry (GC-TOF/MS). Predominantly, 4,4′-DDE, dieldrin, hexachlorobenzene (HCB), lindane and polychlorinated biphenyls (PCBs) were found in most of these common swifts. Only 4,4′-DDE (adult: 83 ± 70 μg/kg, juvenile: 17 ± 39 μg/kg) and dieldrin (adult: 2 ± 3 μg/kg, juvenile: 0.3 ± 1 μg/kg) concentrations were significantly different between adult and juvenile birds. All detected concentrations in our study were far lower than the previously recorded pesticide concentrations of common swifts in Italy and those which are known to cause toxicity and death in birds.

Abstract
The extended distribution and potential introduction of exotic ticks and associated tick-borne pathogens along the northern and southern routes of migratory birds pose zoonotic tick-borne disease risks to wild and domestic animals and incidentally to humans. A knowledge of bird migratory patterns, species of attached ticks, and associated pathogens during their migrations to and from their feeding and nesting grounds is central to understanding associated tick-borne disease risks. Tick-borne disease surveillance was conducted from 2010 to 2011 and 2016 at Hong-do (do = island), Heuksan-do, and Nan-do, major stopovers for migratory birds in Republic of Korea (ROK), as part of the Migratory Birds Research Center bird-banding program for studying bird migration patterns in the ROK. A total of 877 ticks belonging to three genera and nine species were collected, Ixodes turdus (576, 65.7%), Haemaphysalis flava (134, 15.3%), H. longicornis (91, 10.4%), I. nipponensis (56, 6.4%), H. formosensis (7, 0.8%), H. ornithophila (6, 0.7%), H. phasiana (5, 0.6%), H. concinna (1, 0.1%), and Amblyomma testudinarium (1, 0.1%) were collected from 274 birds belonging to 20 genera and 41 species. A total of 15/380 pools (3.95%) were positive for Borrelia species (14 pools of I. turdus and 1 pool of H. flava), while only 1/380 pools (0.26%) was positive for Anaplasma phagocytophilum (1 pool of I. nipponensis). Our findings support the role of migratory birds as possible vectors for the introduction of tick-borne pathogens, which requires continuous monitoring for the potential introduction of ticks and their associated tick-borne pathogens.

Abstract
Background: This study aimed to investigate the occurrence of mcr-1 encoding plasmid-mediated colistin-resistance gene in Escherichia coli isolated from migratory birds in Thailand. Materials and Methods: A total of 178 cloacal swabs from migratory birds was sampled and isolated from 2016 to 2017 in Nan, Trang, and Bangkok, Thailand. The multiplex polymerase chain reaction was used to screen the resistance genes. After screening, a disk diffusion assay and the minimum inhibitory concentration were investigated. The draft genome sequence of isolate 2A85589 was obtained using an Illumina HiSeq X-Ten platform. The genome was assembled using SPAdes 3.0.0. Antimicrobial resistance genes were identified using ResFinder 3.1. Results: We reported E. coli ST101 of isolate 2A85589, an mcr-1-carrying resistance gene isolated from the migratory bird species Hirundo rustica in Thailand. The draft genome of 2A85589 was 4,621,016 bp in size. IncHI1A plasmid was identified using PlasmidFinder with high coverage. In silico analysis detected the presence of eight putative acquired resistance genes, namely blaTEM-1B, mcr-1, mef(A), mef(B), QnrS1, sul3, tet(A), and tet(B), which conferred resistance to β-lactam, colistin, macrolide, quinolone, sulfonamide, and tetracycline. Conclusion: This study underlines the potential risk of the environmental contamination of mcr-1-carrying E. coli isolated from the migratory bird. The long range migration of birds can result in dissemination of mcr-1-carrying bacteria globally. Therefore, plasmid-mediated colistin is an urgent need to be addressed in both human and veterinary medicine for disease control and prevention.

Abstract
The gut microbiota of vertebrates play a crucial role in shaping the health of their hosts. However, knowledge of the avian intestinal microbiota has arguably lagged behind that of many other vertebrates. Here, we examine the intestinal bacterial communities of the hooded crane and the greater white-fronted goose at the Shengjin Lake of China, using high-throughput sequencing (Illumina Mi-Seq), and infer the potential pathogens associated with each species. Intestinal bacterial alpha-diversity in the greater white-fronted goose was significantly higher than that in hooded crane. The intestinal bacterial community compositions were significantly different between the two hosts, suggesting that host interactions with specific communities might have profound implications. In addition, potential pathogens were detected in both guts of the two hosts, suggesting that these wild birds might be at risk of disease and probably spread infectious disease to other sympatric vertebrates. The gut of hooded crane carried more potential pathogens than that of the greater white-fronted goose. The potentially pathogenic community compositions were also significantly different between the two hosts, suggesting the divergence of potentially pathogenic communities between hooded crane, and greater white-fronted goose. Finally, bacterial and potentially pathogenic structures showed strong evidence of phylogenic clustering in both hosts, further demonstrating that each host was associated with preferential and defined bacterial and potentially pathogenic communities. Our results argue that more attention should be paid to investigate avian intestinal pathogens which might increase disease risks for conspecifics and other mixed species, and even poultry and human beings.

Abstract
Introduction: Influenza A viruses have the potential to cause devastating illness in humans and domestic poultry. Wild birds are the natural reservoirs of Influenza A viruses and migratory birds are implicated in their global dissemination. High concentrations of this virus are excreted in the faeces of infected birds and faecal contamination of shared aquatic habitats can lead to indirect transmission among birds via the faecal-oral route. The role of migratory birds in the spread of avian influenza has led to large-scale surveillance efforts of circulating avian influenza viruses through direct sampling of live and dead wild birds. Environmental monitoring of bird habitats using molecular detection methods may provide additional information on the persistence of influenza virus at migratory stopover sites distributed across large spatial scales. Materials and methods: In the current study, faecal and water samples were collected at migratory stopover sites and evaluated for Influenza A by real-time quantitative reverse transcriptase PCR. Results and Discussion: This study found that Influenza A was detected at 53% of the evaluated stopover sites, and 7% and 4.8% of the faecal and water samples, respectively, tested positive for Influenza A virus. Conclusion: Environmental monitoring detected Influenza A at stopover sites used by migratory birds.

Abstract
Migratory birds are considered as vectors of infectious diseases, owing to their potential for transmitting pathogens over large distances. The populations of barn swallow (Hirundo rustica) migrate from Southeast Asia to the Japanese mainland during spring and migrate back to Southeast Asia during autumn. This migratory population is estimated to comprise approximately hundreds to thousands of individuals per year. However, to date, not much is known about the gastrointestinal microbiota of the barn swallow. In this study, we characterized the fecal bacterial community in barn swallow. Using 16S rRNA gene metagenomic sequencing analysis, we examined the presence and composition of potentially pathogenic bacteria in the fecal samples, which were collected during spring season from Osaka. The number (±S.D.) of total bacteria was approximately 2.1(±3.4)×108 per gram of feces. In most samples, the bacterial community composition was dominated by families, such as Enterobacteriaceae, Pseudomonadaceae, Mycoplasmataceae, Enterococcaceae, Streptococcaceae, and Alcaligenaceae. However, no relationship was found between the bacterial community composition and geographical area in the fecal samples. Potentially pathogenic bacteria were detected at the rate of >0.1%, which included Pseudomonas spp., Escherichia/Shigella spp., Enterobacter spp., Yersinia spp., Mycoplasma spp., Enterococcus spp., Achromobacter spp., and Serratia spp. Our results suggested that barn swallow is instrumental in the transmission of these genera over large distances.

Abstract
Aquatic prey subsidies entering terrestrial habitats are well documented, but little is known about the degree to which these resources provide fitness benefits to riparian consumers. Riparian species take advantage of seasonal pulses of both terrestrial and aquatic prey, although aquatic resources are often overlooked in studies of how diet influences the reproductive ecology of these organisms. Ideally, the timing of resource pulses should occur at the time of highest reproductive demand. This study investigates the availability of aquatic (mayfly) and terrestrial (caterpillar) prey resources as well as the nestling diet of the prothonotary warbler (Protonotaria citrea) at two sites along the lower James River in Virginia during the 2014 breeding season. We found large differences in availability of prey items between the two sites, with one having significantly higher mayfly availability. Nestling diet was generally reflective of prey availability, and nestlings had faster mean growth rates at the site with higher aquatic prey availability. Terrestrial prey were fed more readily at the site with lower aquatic prey availability, and at this site, nestlings fed mayflies had higher mean growth rates than nestlings fed only terrestrial prey. Our results suggest that aquatic subsidies are an important resource for nestling birds and are crucial to understanding the breeding ecology of riparian species.

Abstract
In migratory birds, arrival date and hatching date are two key phenological markers that have responded to global warming. A body of knowledge exists relating these traits to evolutionary pressures. In this study, we formalize this knowledge into general mathematical assumptions, and use them in an ecoevolutionary model. In contrast to previous models, this study novelty accounts for both traits-arrival date and hatching date-and the interdependence between them, revealing when one, the other or both will respond to climate. For all models sharing the assumptions, the following phenological responses will occur. First, if the nestling-prey peak is late enough, hatching is synchronous with, and arrival date evolves independently of, prey phenology. Second, when resource availability constrains the length of the pre-laying period, hatching is adaptively asynchronous with prey phenology. Predictions for both traits compare well with empirical observations. In response to advancing prey phenology, arrival date may advance, remain unchanged, or even become delayed; the latter occurring when egg-laying resources are only available relatively late in the season. The model shows that asynchronous hatching and unresponsive arrival date are not sufficient evidence that phenological adaptation is constrained. The work provides a framework for exploring microevolution of interdependent phenological traits.

Abstract
Susceptibility to infection varies by species, and asymptomatic birds could be carriers. In January 2014, an outbreak of infection with highly pathogenic avian influenza (HPAI) A(H5N8) virus began on a duck farm in South Korea and spread to other poultry farms nearby. During this outbreak, many sick or dead wild birds were found around habitats frequented by migratory birds. To determine the causes of death, we examined 771 wild bird carcasses and identified HPAI A(H5N8) virus in 167. Gross and histologic lesions were observed in pancreas, lung, brain, and kidney of Baikal teals, bean geese, and whooper swans but not mallard ducks. Such lesions are consistent with lethal HPAI A(H5N8) virus infection. However, some HPAI-positive birds had died of gunshot wounds, peritonitis, or agrochemical poisoning rather than virus infection. These findings suggest that susceptibility to HPAI A(H5N8) virus varies among species of migratory birds and that asymptomatic migratory birds could be carriers of this virus.

Abstract
Three echinostome species, i.e., Patagifer bilobus, Petasiger neocomense, and Saakotrema metatestis, are newly recorded in the trematode fauna of the Republic of Korea. They were recovered from 3 species of migratory birds (Platalea minor, Podiceps cristatus, and Egretta garzetta), which were donated by the Wildlife Center of Chungbuk (WCC) and the Conservation Genome Resource Bank for Korean Wildlife (CGRB). Only 1 P. bilobus specimen was recovered from the intestine of a black-faced spoonbill (P. minor), and characterized by the bilobed head crown with a deep dorsal incision and 54 collar spines. Twenty P. neocomense were recovered from the intestine of a great crested grebe (P. cristatus), and they had a well-developed head crown with 19 spines and 2 testes obliquely located at the posterior middle of the body. Total 70 S. metatestis were collected from the bursa of Fabricius of 1 little egret (E. garzetta). It is characterized by stout tegumental spines covered in the entire leaf-shaped body, posterior extension of the uterus, presence of the uroproct and a well-developed head crown with 12 pairs of collar spines on each side. By the present study, these 3 echinostome species are newly added to the trematode fauna in Korea.
