Harmful Algal Bloom Toxins in Alaska Seabirds
Elevated ocean temperatures are linked to the development of harmful algal blooms (HABs). Toxins from these blooms may pose health threats to marine organisms, including seabirds. Since 2015, the USGS has worked with a variety of stakeholders to develop testing methods and research projects to better understand the geographic extent, timing and impacts of algal toxins in Alaska marine ecosystems...
Changing Arctic Ecosystems
Arctic regions of Alaska are important for cultural and economic sustainability and host a wide variety of wildlife species, many of which are of conservation and management interest to the U.S. Department of the Interior. The USGS and collaborators provide information about Arctic ecosystems that are used by Arctic residents, management agencies, and industry.
Loon Research
Scientists at the USGS Alaska Science Center have conducted research on Alaska’s three loon species since the late 1970s. Loons rely on freshwater lakes for nesting habitat and fish and invertebrates inhabiting lakes and marine ecosystems for food. All three loon species in Alaska occur within the National Petroleum Reserve-Alaska (NPR-A) on Alaska’s northern coast. Research by the USGS is...
Landbird Research in Alaska
On this page, learn about USGS work on Beak Deformities and Boreal Partners in Flight.
Annual Data and Model-based Estimates of Pacific Black Brant Age Ratios
Pacific brant are an Arctic-breeding sea goose that stage and feed on seagrasses during the non-breeding season in coastal areas of Alaska. Brant are an important subsistence and sport harvest species and the focus of several population surveys by state and federal agencies. Each fall the entire population stages during migration in Izembek Lagoon, Alaska, presenting a unique opportunity to survey...
Boreal Partners in Flight
WELCOME to the Alaska Landbird Resource Information System, the official web site for Boreal Partners in Flight! Thanks for taking the time to learn more about the Boreal Partners in Flight program and our efforts to understand and conserve northern populations of landbirds.
Tracking Data for Bar-tailed Godwits (Limosa lapponica)
Available here are tracking data for two subspecies of Bar-tailed Godwits. One of the subspecies, Limosa lapponica baueri , nests in Alaska and spends the nonbreeding season in New Zealand and eastern Australia whereas L.l.menzbieri nests in Siberia and spends the nonbreeding season in western Australia. This study was the first to describe the year-round movements of these extremely long-distance...
Waterfowl Research
Scientists at the USGS Alaska Science Center have conducted research on waterfowl species (ducks, geese, and swans) in Alaska since the 1970s. Because Alaska is an international crossroads of migratory bird flyways, with millions of birds from Asia and North America breeding in Alaska each summer, USGS research has also taken place in adjacent countries (Russia, Japan, Canada, Mexico) and in the...
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 chronology...
Tracking Data for Long-tailed Ducks (Clangula hyemalis)
Available here are tracking data of long-tailed duck, a species of seaduck that breeds throughout the circumpolar Arctic and spends the winter in coastal areas of northern and mid latitudes. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.
Tracking Data for Common Eiders (Somateria mollissima)
Available here are tracking data of Common Eider, a sea duck species found across Alaska and the Arctic. Some populations migrate between distant breeding and wintering areas while others are essentially nonmigratory. These data were collected to better understand the migration of the different populations in Alaska and migratory connectivity to adjacent regions, such as Russia.
Tracking Data for Whooper Swans (Cygnus cygnus)
Available here are tracking data for the whooper swan, a Eurasian species that closely resembles the trumpeter swan in North America. These data were collected to better understand the potential transmission of avian influenza viruses carried by swans and provide information on the migratory habits of whooper swans in East Asia.
