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.
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...
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 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 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 Surf Scoters (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.
