Avian influenza antibody prevalence increases with mercury contamination in wild waterfowl Avian influenza antibody prevalence increases with mercury contamination in wild waterfowl
Environmental contamination is widespread and can negatively impact wildlife health. Some contaminants, including heavy metals, have immunosuppressive effects, but prior studies have rarely measured contamination and disease simultaneously, which limits our understanding of how contaminants and pathogens interact to influence wildlife health. Here, we measured mercury concentrations...

Spatiotemporal changes in influenza A virus prevalence among wild waterfowl inhabiting the continental United States throughout the annual cycle Spatiotemporal changes in influenza A virus prevalence among wild waterfowl inhabiting the continental United States throughout the annual cycle
Avian influenza viruses can pose serious risks to agricultural production, human health, and wildlife. An understanding of viruses in wild reservoir species across time and space is important to informing surveillance programs, risk models, and potential population impacts for vulnerable species. Although it is recognized that influenza A virus prevalence peaks in reservoir waterfowl in...

Highly pathogenic avian influenza (HPAI): An emerging disease threat in North America Highly pathogenic avian influenza (HPAI): An emerging disease threat in North America
Highly pathogenic avian influenza (HPAI) is an ecologically and economically significant avian disease that is quickly spreading among wild and domestic birds throughout North America. In this blog post, we provide information and resources that can help you to be informed, be prepared, and be ready to take appropriate action should you observe wild birds that may be affected by HPAI.

Maintenance and dissemination of avian-origin influenza A virus within the northern Atlantic Flyway of North America Maintenance and dissemination of avian-origin influenza A virus within the northern Atlantic Flyway of North America
Wild waterbirds, the natural reservoirs for avian influenza viruses, undergo migratory movements each year, connecting breeding and wintering grounds within broad corridors known as flyways. In a continental or global view, the study of virus movements within and across flyways is important to understanding virus diversity, evolution, and movement. From 2015 to 2017, we sampled waterfowl...

Genomically diverse carbapenem resistant Enterobacteriaceae from wild birds provide insight into global patterns of spatiotemporal dissemination Genomically diverse carbapenem resistant Enterobacteriaceae from wild birds provide insight into global patterns of spatiotemporal dissemination
Carbapenem resistant Enterobacteriaceae (CRE) are a threat to public health globally, yet the role of the environment in the epidemiology of CRE remains elusive. Given that wild birds can acquire CRE, likely from foraging in anthropogenically impacted areas, and may aid in the maintenance and dissemination of CRE in the environment, a spatiotemporal comparison of isolates from different...

Genetic assignment of fisheries bycatch reveals disproportionate mortality among Alaska Northern Fulmar breeding colonies Genetic assignment of fisheries bycatch reveals disproportionate mortality among Alaska Northern Fulmar breeding colonies
Global fisheries kill millions of seabirds annually through bycatch, but little is known about population-level impacts, particularly in species that form metapopulations. U.S. North Pacific groundfish fisheries catch thousands of Northern Fulmars (Fulmarus glacialis rodgersii) each year, making fulmars the most frequently caught seabird in federally managed U.S. fisheries. Here, we used...

Highly pathogenic avian influenza is an emerging disease threat to wild birds in North America Highly pathogenic avian influenza is an emerging disease threat to wild birds in North America
Prior to the emergence of the A/goose/Guangdong/1/1996 (Gs/GD) H5N1 influenza A virus, the long-held and well-supported paradigm was that highly pathogenic avian influenza (HPAI) outbreaks were restricted to poultry, the result of cross-species transmission of precursor viruses from wild aquatic birds that subsequently gained pathogenicity in domestic birds. Therefore, management...

Antimicrobial resistance: Wildlife as indicators of anthropogenic environmental contamination across space and through time Antimicrobial resistance: Wildlife as indicators of anthropogenic environmental contamination across space and through time
Prior assessments support wildlife as indicators of anthropogenically influenced antimicrobial resistance across the landscape. A ground-breaking new study suggests that wildlife may also provide information on antimicrobial resistance in the environment through time.

Assessment of variation in the detection and prevalence of blood parasites among sympatrically breeding geese in western Alaska, USA Assessment of variation in the detection and prevalence of blood parasites among sympatrically breeding geese in western Alaska, USA
Haemosporidian parasites may impact avian health and are subject to shifts in distribution and abundance with changing ecologic conditions. Therefore, understanding variation in parasite prevalence is important for evaluating biologically meaningful changes in infection patterns and associated population level impacts. Previous research in western Alaska, US, indicated a possible...

Evidence for interannual persistence of infectious influenza A viruses in Alaska wetlands Evidence for interannual persistence of infectious influenza A viruses in Alaska wetlands
Influenza A viruses (IAVs) deposited by wild birds into the environment may lead to sporadic mortality events and economically costly outbreaks among domestic birds. There is a paucity of information, however, regarding the persistence of infectious IAVs within the environment following deposition. In this investigation, we assessed the persistence of 12 IAVs that were present in the...
