The data set consists of data collected in 1995, 1996, and 1997 in wetlands in the Prairie Pothole Region of North Dakota and South Dakota. The data were summarized and used in the analysis for two publications in peer-reviewed journals. The data consists of one data set that includes bird abundance and richness data, wetland class (temporary, seasonal, semipermanent, permanent, alkali), and wetland type (private or federal). In conjunction with surveys of wetland birds, the following wetland variables also were recorded: wetland size, date, local-level habitat variables (percent coverage of open water, emergent vegetation, wet meadow, and shoreline/mudflat), and landscape-level habitat variables (percent cover...

The data are part of a larger, long-term project of lesser scaup on Lower Red Rock Lake, Montana, 2004-2015, conducted by the US Fish and Wildlife Service. This segment of the data has summarized results of late summer resighting surveys of nasal-marked adult females and GIS-derived habitat attributes. Scaup resighting surveys were conducted mid-August to early September, 2007-2013. The study site was divided into 16 survey plots (as shown as grid in figure); each plot comprised one to four 750 × 750 m survey blocks such that plots contained roughly equivalent area of open water Survey data included GPS location, number, and social status of marked females, wind conditions, and group size of other scaup associated...

The data set consists of data to evaluate bias in roadside surveys of secretive marsh birds in 2008 and 2009 in wetlands in the Prairie Pothole Region of Minnesota, North Dakota, and South Dakota during three survey periods (survey number). The data set includes detection values (species heard, species seen, species seen and heard) of seven focal marsh bird species (four-letter alpha codes and scientific names [genus and species]) by paired basin regime (temporary, seasonal, semipermanent, lake) locations using play-callback recordings and passive listening, and the detection distance to each species. In conjunction with surveys of wetland birds, the following location, weather and wetland features were recorded:...
The data set consists of data collected in 1995, 1996, and 1997 in wetlands in the Prairie Pothole Region of North Dakota and South Dakota. The data were summarized and used in the analysis for a U.S. Geological Survey Open File Report entitled: The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota. The data consist of two data sets. A species data set includes the common names, scientific names (species and genus), and four-letter alpha codes for 133 bird species observed during the three-year study. The bird abundance data set includes the abundance of wetland birds by wetland class (temporary, seasonal, semipermanent, permanent, alkali),...
The continental population of scaup ( Aythya affinis and A. marila) fell to >30% below the 1955-2008 average, and ~3 million birds below the North American Waterfowl Management Plan (NAWMP) goal of 6.3 million. Reviews of long-term databases noted a decrease in the sex and age ratios (number of females relative to males and number of immatures relative to adults, respectively) of lesser scaup in the U.S. harvest. These results indicate that recruitment and female survival of lesser scaup has declined during this period. Recruitment is the product of several demographic rates, including female survival during the breeding season, breeding propensity, nesting success, and duckling survival. Previous life-cycle models...

Population size and trends of most North American marsh bird species are poorly known, and continental marsh bird surveys are being proposed to provide better insight into marsh bird populations. The Prairie Pothole Region (PPR) is a critical and expansive breeding area for several focal marsh bird species (Beyersbergen et al. 2004). The study described here supports development of a regional and national monitoring program by furnishing data that can be used to develop models that relate roadside counts of marsh birds in the PPR to counts obtained from off-road sites for which access is more difficult. Roadside surveys (i.e. point-count surveys conducted from the road right-of-way) are being considered as a technique...
