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...
Does fish prey influence red-throated loon productivity?
This study will evaluate the nearshore marine feeding areas of breeding adult red-throated loons and assess the response of loon reproductive success to differences in the relative abundance, composition, and nutritional content of nearshore fish communities that vary in space and time.
Tracking Data for Emperor Geese (Anser canagicus)
Available here are tracking data for the Emperor Goose, an endemic waterfowl species to the Bering Sea region that breeds primarily in western Alaska on the Yukon-Kuskokwim Delta and spends the winter in southwestern Alaska and throughout the Aleutian Islands. These data were collected to better understand the migratory patterns, winter habitat use, and annual survival of emperor geese.
Tracking Data for Surf Scoter (Melanitta perspicillata)
Available here are tracking data of Surf 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 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
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.
