www.pwrc.usgs.gov — Breeding Bird Survey (BBS) is a project monitored by the USGS and the Canadian Wildlife Service on the status and trends of North American bird populations. The data can be used to estimate population trends and relative abundances at various scales. The BBS is a cooperative effort between the U.S. Geological Survey's Patuxent Wildlife Research More...

www.werc.usgs.gov — Mercury is a contaminant of significant concern in waterbirds because it can accumulate to high concentrations in their tissues and cause deleterious effects such as impaired reproduction. Numerous studies and monitoring programs have evaluated concentrations of mercury in waterbird tissues as an index of risk to exposure. However, no single More...

pubs.er.usgs.gov — This report presents the results of the 2006 International Census of Piping Plovers (Charadrius melodus). Two sets of tabular data are reported: one for distribution and abundance of wintering Piping Plovers, the other for distribution and abundance of breeding Piping Plovers. The winter census resulted in the observation of 3,884 Piping Plovers 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...
