Science and Products
Tracking Data for Black Scoter (Melanitta americana)
Available here are tracking data of Black Scoter, a duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. These data were collected to better understand the timing and patterns of migratory movements between breeding and wintering areas.
Tracking Data for Pacific Loons (Gavia pacifica)
Available here are tracking data of Pacific Loons, a species that breeds throughout much of Alaska and winters throughout the Pacific Ocean basin, along the costs of East Asia and the U.S. These data were collected to better understand timing of spring arrival, fall departure, and habitat use patterns on the North Slope of Alaska.
Tracking Data for Tundra Swans (Cygnus columbianus)
Available here are tracking data of Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of habitats in breeding, wintering, and migratory areas of North America.
Tracking Data for Yellow-billed Loons (Gavia adamsii)
Available here are tracking data of Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada. This species winters along the Pacific coasts of North America and Eurasia. These data were collected to better understand the patterns of migratory movements and seasonal use of different regions of Alaska
Swan Research
USGS research on swans in Alaska has focused on pathogens, contaminants, and demographic rates in each of the different breeding areas of Alaska. The vastly different migration patterns of swans in Alaska means that there are multiple factors on the wintering grounds and during migration that may influence population size and trends.
Community Outreach and Engagement
It is critically important that Alaska Native, rural communities and tribal organizations and Alaska co-management councils are kept informed of USGS research activities and findings. Involvement of and collaboration with students also provides valuable perspectives to USGS science. This page offers information on how USGS communicates its activities and seeks opportunities to gain important...
Tracking Data for Blue-winged Teal (Anas discors)
Available here are tracking data of Blue-winged Teal, a duck species that breeds throughout much of North America and whose wintering range includes neotropical areas of the Caribbean and Central and South America, thus providing a migratory link between the continents of North and South America. These data were collected to better understand the timing and patterns of migratory movement of...
Tracking Data for Red-throated Loons (Gavia stellata)
Available here are tracking data of Red-throated Loons, a species that breeds in coastal areas throughout Alaska and winters along the Pacific coasts of North America and Eurasia. These data were collected to better understand the patterns of migratory movements and seasonal use of different regions of Alaska.
Tracking Data for Northern Pintails (Anas acuta)
Available here are tracking data of Northern Pintails, a duck species that, in Alaska, nests throughout the state and in adjacent regions of Russia and Canada. These data were collected to better understand the timing and patterns of migratory movements of Northern Pintails from wintering grounds in Japan as part of a project on the possible spread of Eurasian forms of avian influenza to North...

Movements and habitat use of loons for assessment of conservation buffer zones in the Arctic Coastal Plain of northern Alaska
Oil and gas development in the Arctic Coastal Plain, Alaska, may pose threats to wildlife. Management guidelines within the National Petroleum Reserve-Alaska dictate buffer zones for coastal wildlife habitat and for breeding and foraging sites of yellow-billed loons (YBLOs; Gavia adamsii), a species of conservation concern. However, few data...

Visualizing populations of North American sea ducks: Maps to guide research and management planning
North American sea ducks generally breed in mid- to northern-latitude regions and nearly all rely upon marine habitats for much of their annual cycle. Most sea duck species remained poorly studied until the 1990s when declines were noted in several species and populations. Subsequent research, much of which was funded by the Sea Duck Joint Venture...
