www.absc.usgs.gov — This site links to a database of bird distribution which looks at patterns in the numbers of birds detected among Alaska Off-road Breeding Bird Survey routes. The database can be searched in two different ways: by area, and by species. To find out more about the data contained in the database of bird distribution, take a look at the metadata page, More...

www.cerc.usgs.gov — The primary goal of the proposed research is to evaluate selenium and atrazine exposure and effects to fish, amphibians, and waterfowl that utilize the Refuge. The following subordinate objectives will be met to investigate selenium exposure and effects to wildlife on the Refuge: 1.Measure selenium concentrations and total organic content in More...

alaska.usgs.gov — Remote sensing technology has been used to fill key information gaps on how the tribe Numeniini, to which godwits and curlews belong, migrate within and across continents. During 2007-2008, four species (Bar-tailed Godwit, Hudsonian Godwit, Bristle-thighed Curlew, and Long-billed Curlew) - representative of the various migration strategies More...

www.pwrc.usgs.gov — The North American Bird Phenology Program houses a unique and largely forgotten collection of six million Migration Observer Cards that illuminate migration patterns and population status of birds in North America. These handwritten cards contain almost all of what was known of bird status from the Second World War back to the later part of the More...

alaska.usgs.gov — It is estimated that 100,000-150,000 Bar-tailed Godwits breed in Alaska. Under the US Shorebird Conservation Plan, they are a species of High Concern mainly due to their small population size, threats to their non-breeding grounds (especially at migratory stopover sites in Asia), and their relatively restricted breeding distribution within the More...

alaska.usgs.gov — This resource is a life history profile of the Bristle-thighed Curlew (Numenius tahitiensis). The Bristle-thighed Curlew (Numenius tahitiensis) breeds only in North America. Its adult population numbers about 7,000 individuals, making it the rarest of the New World curlews and godwits. It is similar in appearance to the Whimbrel (N. phaeopus). More...

www.umesc.usgs.gov — Little is known about the movements of common loons (Gavia immer) during migrations and on wintering ranges in coastal waters. This information is needed to formulate effective regional and national conservation strategies. UMESC has collaborated with regional partners in the use of satellite telemetry to study the movements of common loons More...

srfs.wr.usgs.gov — The International Shorebird Survey (ISS) in the eastern and central United States and the Maritimes Shorebird Survey in southeastern Canada have been conducted for more than 20 years and provide a wealth of information about how to survey shorebirds in these areas through both national and regional monitoring programs. Enormous progress has been More...

www.fort.usgs.gov — The need for a single source of information about the management of waterfowl and their habitat was originally suggested by the north-central region of the U.S. Fish and Wildlife Service. Much of this information exists in scientific papers, unpublished reports, or has never been recorded, and thus is not readily accessible by waterfowl managers. More...

www.fort.usgs.gov — Identifying linkages between the seasonal habitats of migratory birds, especially neotropical migrants, is critical to conservation efforts and to effectively focus management actions. For most neotropical migrants, however, virtually nothing is known about which habitats are limiting, because the links between their seasonal habitats on different More...

alaska.usgs.gov — Mountains are the single dominant physiographic feature throughout most of Alaska. Indeed, mountains are such a defining feature of arctic Alaska and Beringia that they account for over 20 percent of the land area in the entire Holarctic (excluding the Greenland ice sheet). Not surprisingly, the avifauna of the region has been strongly More...

www.umesc.usgs.gov — Scientists with the U.S. Geological Survey and the Wisconsin Department of Natural Resources are evaluating a new way of monitoring movements and behavior of common loons. Miniature archival geolocator tags were attached to 18 adult common loons in northern Wisconsin this past summer.
