Walrus Research
The USGS Alaska Science Center conducts long-term research on the Pacific walrus to provide scientific information to Department of Interior management agencies and Alaska Native co-management partners. In addition, the USGS Pacific walrus research program collaborates with the U.S. Fish and Wildlife Service (USFWS) and the State of Alaska’s Department of Fish and Game and Alaska Native co...

Q&A: Vessel Cruise for Estimates of Pacific Walrus Demography
Adult female and juvenile Pacific walruses reside in the northern Bering Sea and Chukchi Sea in the late spring and summer. In June of 2024, the U.S. Fish and Wildlife Service and the USGS will again conduct a walrus research cruise on the Research Vessel Norseman II. The cruise will depart from Nome, Alaska on May 31, 2024, and return to Nome on June 28, 2024. The research cruise will be...
Restoration of Common Loons in Minnesota
During the breeding season (late March to early September), common loons can be found in the northern United States, and portions of Alaska and Canada. Common loons nest in lakes that range in size from 12 acres to over 10,000 acres. Nests are generally found near shore in a protected bay or in the lee of islands. Common loons prefer to nest on clear lakes with abundant small fish and are...
Greater White-Fronted Goose Habitat Analysis
The greater white-fronted goose ( Anser albifrons) is generally found in natural wetlands and agricultural lands but can also be found in grasslands, wet tundra, and coastal marshes, where they feed on seeds, grains, grasses, and berries. In recent years there has been a decline in greater white-fronted geese in Louisiana during the winter. Winter counts of greater white-fronted geese in Illinois...
Q&A: Estimates of Abundance for Pacific Walrus
The Pacific walrus ranges across the Bering and Chukchi seas during the year. This wide geographic distribution makes it difficult to estimate Pacific walrus population abundance. However, recent technological advances in genetics and drone imagery have generated precise regional and range-wide abundance estimates.
