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:...
This dataset describes features of 2941 duck nests that were found in the Prairie Pothole Region of North and South Dakota during 2002-2003. Nest features include estimated initiation date, incubation stage and status as active. The dataset accompanies a scientific journal article describing an evaluation of the density and success of duck nests in conservation fields in 36 study areas that were seeded with native or tame grasses. Field features in this dataset include seeding treatment, planted area, and area of grassland patch.
A biologist and field crew from Northern Prairie Wildlife Research Center visited sites nine times throughout the breeding season (late May to mid-July) to record counts of grassland birds. Surveyors applied North American Breeding Bird Survey methodology to obtain counts at On-, Near-, and Off-road Stops, but unlike the North American Breeding Bird Survey, which features a single survey at each site, three replicate surveys were conducted on back-to-back-to-back days during each survey period to facilitate estimation of detection and occupancy probabilities. Assignment of surveyors to individual sites followed a design protocol that allows observer effects to also be estimated. The biologist visited each site once...

This dataset presents four tabular data files that evaluate the effect of predator exclosures around piping plover (Charadrius melodus) nests on plover nest, chick, within-season, and annual adult survival. During 2014-2016, we designed an experiment to examine nest (n = 418), chick (n = 453), and adult (n = 367) survival at alkaline wetlands of the Northern Great Plains. Alkaline wetlands were divided between treatment wetlands and control wetlands (no exclosures placed anywhere on wetland). Field crews aimed to place predator exclosures around half of all plover nests found resulting in three treatment types: uncaged nest on control wetland, uncaged nest on treatment wetland, and caged nest on treatment wetland....
This data set is part of a data release as a companion to a manuscript titled "Foraging movements and colony attendance of least terns (Sternula antillarum) on the central Platte River". This data release includes three tabular digital data file representing movement patterns, behaviors, and foraging success of least terns that nested on sandpits near the Platte River during 2009 and 2010. Movement, behavior, and foraging data were collected at the sandpits where birds nested as well as on riverine sites.
