Influenza A antibodies in Pacific (Gavia pacifica), Red-throated (G. stellata), and Yellow-billed Loons (G. adamsii) in Alaska, 2008-2017 Influenza A antibodies in Pacific (Gavia pacifica), Red-throated (G. stellata), and Yellow-billed Loons (G. adamsii) in Alaska, 2008-2017
This data set contains three spreadsheets with results of Influenza A Virus (IAV) screening in blood from Pacific, Red-throated, and Yellow-billed Loons at three locations in Alaska. Loons were captured along the Beaufort Sea Coast, Chukchi Sea Coast, and Yukon-Kuskokwim Delta from 2008-2017. Three different tests were used and the results are presented in separate spreadsheets. All...

This data release contains a mark-resight encounter history table for Pacific and Yellow-billed loons from the Arctic Coastal Plain in northern Alaska, 2011-2014.
Pacific (Gavia pacifica), Yellow-billed (G. adamsii), and Red-throated Loon (G. stellata) Nest Monitoring Data; National Petroleum Reserve-Alaska, 2011-2014 Pacific (Gavia pacifica), Yellow-billed (G. adamsii), and Red-throated Loon (G. stellata) Nest Monitoring Data; National Petroleum Reserve-Alaska, 2011-2014
This data set contains information (in two spreadsheets) from the monitoring of nests of Pacific, Yellow-billed and Red-throated loons at two 64 km2 sites in the National Petroleum Reserve-Alaska (NPR-A) during the summers of 2011-2014. We categorized each nest site by the physical aspects of the lake and proximity to other nesting loons. To determine nest fate (incubating, nest...
Serological data on influenza A from birds and mammals on the Arctic Coastal Plain of northern Alaska, 2011-2017 Serological data on influenza A from birds and mammals on the Arctic Coastal Plain of northern Alaska, 2011-2017
These data (in two spreadsheets) are the results of screening for influenza A viruses (IAV) in blood from wild animals that utilize the Arctic region of Alaska. 758 blood samples from nine wildlife species (3 mammal, 6 waterbird) were collected in Arctic Alaska, 2011-2017. Two different tests were used and the results are presented in separate spreadsheets. All blood samples were...
Data for Evaluating Efficacy of 1- versus 2-prong Radio Transmitter Attachment for Scoters in Alaska and Washington, 2008-2010 Data for Evaluating Efficacy of 1- versus 2-prong Radio Transmitter Attachment for Scoters in Alaska and Washington, 2008-2010
A major challenge of wildlife telemetry is choosing an attachment technique that maximizes transmitter retention while minimizing negative side effects. For waterbirds, attachment of transmitters with subcutaneous anchors has been an effective and well-established technique, having been used on >40 species. This method was recently modified to include a second subcutaneous anchor...

Antibiotic-resistant Escherichia coli in migratory birds inhabiting remote Alaska Antibiotic-resistant Escherichia coli in migratory birds inhabiting remote Alaska
We explored the abundance of antibiotic-resistant Escherichia coli among migratory birds at remote sites in Alaska and used a comparative approach to speculate on plausible explanations for differences in detection among species. At a remote island site, we detected antibiotic-resistant E. coli phenotypes in samples collected from glaucous-winged gulls (Larus glaucescens), a species...

International migration patterns of Red-throated Loons (Gavia stellata) from four breeding populations in Alaska International migration patterns of Red-throated Loons (Gavia stellata) from four breeding populations in Alaska
Identifying post-breeding migration and wintering distributions of migratory birds is important for understanding factors that may drive population dynamics. Red-throated Loons (Gavia stellata) are widely distributed across Alaska and currently have varying population trends, including some populations with recent periods of decline. To investigate population differentiation and the...

A suspended dive-net technique for catching territorial divers A suspended dive-net technique for catching territorial divers
A variety of methods such as night-lighting and lift nets have been used to catch divers (Gavidae), although 24-hour daylight in the Arctic summer and the remote nature of field sites can make the use of these traditional methods impossible. Our research required capture of adult divers at remote locations in northern Alaska. Here we describe a suspended dive-net technique that we used...

Interacting effects of latitude, mass, age, and sex on winter survival of Surf Scoters (Melanitta perspicillata): Implications for differential migration Interacting effects of latitude, mass, age, and sex on winter survival of Surf Scoters (Melanitta perspicillata): Implications for differential migration
We quantified variation in winter survival of Surf Scoters (Melanitta perspicillata (L., 1758)) across nearly 30° of latitude on the Pacific coast of North America to evaluate potential effects on winter distributions, including observed differential distributions of age and sex classes. We monitored fates of 297 radio-marked Surf Scoters at three study sites: (1) near the northern...

Nest visits and capture events affect breeding success of Yellow-billed and Pacific loons Nest visits and capture events affect breeding success of Yellow-billed and Pacific loons
Accurate estimates of breeding success are essential for understanding population dynamics and for managing populations. Unfortunately, research activities to collect these data can negatively impact the breeding success of the study species and bias estimates of breeding success. Despite the potential for negative impacts, few studies have documented the effect of capturing incubating...
