Bird Species Checklists from USGS Alaska Science Center Field Camps
Scientists from the USGS Alaska Science Center regularly work in remote field camps, often for days or weeks at a time. Though not the primary research focus of these camps, many researchers maintain daily checklists of all bird species encountered during field work. These checklists can provide documentation of the presence, distribution, timing of arrival and departure, and breeding...
Avian Influenza Research
Since 2006, the USGS Alaska Science Center has been part of the State and Federal interagency team for the detection and response to highly pathogenic (HPAI) viruses in North America. Avian influenza or "bird flu" is a viral disease that primarily infects domestic poultry and wild birds. Avian influenza viruses are naturally occurring in wild birds such as ducks, geese, swans, and gulls. These...
Evidence for continental-scale dispersal of antimicrobial resistant bacteria by landfill-foraging gulls
Anthropogenic inputs into the environment may serve as sources of antimicrobial resistant bacteria and alter the ecology and population dynamics of synanthropic wild animals by providing supplemental forage. In this study, we used a combination of phenotypic and genomic approaches to characterize antimicrobial resistant indicator bacteria, animal...

Satellite tracking of gulls and genomic characterization of fecal bacteria reveals environmentally mediated acquisition and dispersal of antimicrobial resistant Escherichia coli on the Kenai Peninsula, Alaska
Gulls (Larus spp.) have frequently been reported to carry Escherichia coli exhibiting antimicrobial resistance (AMR E. coli); however, the pathways governing the acquisition and dispersal of such bacteria are not well-described. We equipped 17 landfill-foraging gulls with satellite transmitters and collected gull fecal samples longitudinally from...
Ahlstrom, Christina; Bonnedahl, Jonas; Woksepp, Hanna; Hernandez, Jorge; Reed, John; Tibbitts, Lee; Olsen, Björn; Douglas, David C.; Ramey, Andrew M. Blood parasite infection data from Blue-winged teal, Canada (Alberta, Saskatchewan) and USA (Texas, Louisiana), 2012-2013
This data set includes age, sex, location, and blood parasite infection data from Blue-winged teal (Anas discors) captured in Canada (Alberta, Saskatchewan) and the USA (Texas, Louisiana) in 2012-2013. Infection data for three different genera of blood parasites are given as are GenBank accession numbers for genetic sequences obtained from...
Reed, John Evidence for the exchange of blood parasites between North America and the Neotropics in blue-winged teal (Anas discors)
Blue-winged teal (Anas discors) are abundant, small-bodied dabbling ducks that breed throughout the prairies of the northcentral USA and central Canada and that winter in the southern USA and northern Neotropics. Given the migratory tendencies of this species, it is plausible that blue-winged teal may disperse avian pathogens, such as parasites...
Ramey, Andrew M.; Reed, John A.; Walther, Patrick; Link, Paul; Schmutz, Joel A.; Douglas, David C.; Stallknecht, David E.; Soos, Catherine Habitat use and foraging patterns of molting male Long-tailed Ducks in lagoons of the central Beaufort Sea, Alaska
From mid-July through September, 10 000 to 30 000 Long-tailed Ducks (Clangula hyemalis) use the lagoon systems of the central Beaufort Sea for remigial molt. Little is known about their foraging behavior and patterns of habitat use during this flightless period. We used radio transmitters to track male Long-tailed Ducks through the molt period...
Flint, Paul L.; Reed, John A.; Deborah Lacroix; Richard Lanctot Long-term effects of the 'Exxon Valdez' oil spill: Sea otter foraging in the intertidal as a pathway of exposure to lingering oil
The protracted recovery of some bird and mammal populations in western Prince William Sound (WPWS), Alaska, and the persistence of spilled 'Exxon Valdez' oil in intertidal sediments, suggests a pathway of exposure to consumers that occupy nearshore habitats. To evaluate the hypothesis that sea otter (Enhydra lutris) foraging allows access to...
