Available here are tracking data for the largest shorebird in North America, the long-billed curlew. This species nests in deserts and grasslands of central and western North America and spends the nonbreeding season in agriculture fields and pastures or along coastlines in California, Texas, and Mexico. These data were collected to better understand the migratory patterns of this unmistakable and...

Available here are tracking data of Caribou, an ungulate that ranges between the Alaska Peninsula, up through interior Alaska and the Arctic Coastal Plain, and over to the Yukon Territory. These data were collected from animals living in three different herds including the Fortymile herd, Nelchina herd, and Denali herd.

Available here are tracking data of buff-breasted sandpiper, a shorebird species that breeds only in Arctic Alaska and Canada, spending the winter in the grasslands of Brazil, Uruguay, and Argentina after a lengthy migration. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.

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.

Available here are tracking data for the Marbled Murrelet, a seabird species that forages in coastal marine waters and nests in old-growth forests of Alaska, Canada, and the western United States.

Available here are tracking data of Lesser Yellowlegs ( Tringa flavipes). These data were collected to inform the spatiotemporal migratory patterns of Lesser Yellowlegs between subarctic breeding areas in Alaska and Canada and wintering areas in South America, the Caribbean, Central America, and the contiguous United States.

Available here are tracking data of the Steller’s Eider, a species of seaduck that breeds throughout the circumpolar Arctic and spends the winter in coastal areas of western and southwestern Alaska. The Alaska-breeding population is listed as threatened under provisions of the Endangered Species Act. These tracking data were collected by the U.S. Fish and Wildlife Service. The entire data package...

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...

Available here are tracking data of Pacific walrus, a marine mammal that ranges between the Alaska Peninsula, up through the Bering and Chukchi seas, and over to Russia. These data were collected from animals marked in the northern Bering and Chuckchi sea to understand seasonal movement patterns, use of coastal haulouts in northwestern Alaska, and determine estimates of abundance in autumn.

Available here are tracking data for the Black Brant, a goose species that breeds in coastal areas of Alaska, northwestern Canada, and northeastern Russia and winters along coastal areas of North America from western Alaska to Mexico.

Available here are tracking data for the red-faced cormorant, a seabird species that is found only in the North Pacific Ocean, breeding and wintering from southern Alaska and throughout the Aleutian Islands to Far Eastern Russia. These data were collected to better understand the migratory patterns of red-faced cormorants that breed in the Aleutian Islands.

Available here are tracking data of Spectacled Eider, a sea duck species that breeds only in Alaska and Russia and spends the winter exclusively in the Bering Sea. The Alaska breeding population is listed as threatened under provisions of the Endangered Species Act. These data were collected to better understand the winter distribution in the Bering Sea and locate birds for winter aerial surveys...
