www.werc.usgs.gov — Working closely with several environmental groups in Malawi, Nigeria, and Mali, the task of this project is to deploy solar satellite transmitters (size in grams) on three species of wild ducks including garganey (12g), white-faced whistling ducks (18g), and comb ducks (30g). These represent a continental migrant, an African migrant, and a More...

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...

fresc.usgs.gov — The Conservation Genetics Lab carries out molecular analysis, pedigree analysis, modeling, data management, and cryogenic sample repository. As a part of this research, the lab investigates the effectiveness of molecular markers used to enhance enforcement of the Endangered Species Act policy. During the past 15 years, this research has involved 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 — 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...

www.umesc.usgs.gov — This web resource is a tool for mapping and modeling migratory birds for bird conservation planning. The focus of this study is to develop statistically sound, science-based models to support public land management for high priority bird species within a regional context. The site links to a Project Description, Modeling Avian Abundance, Desktop More...
