This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validation model selection procedure was used to select the best model for each species.

This data product consists of a database of population change and relative abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented in 6 separate spreadsheets for 2 methods of trend summary and 3 time periods for 548 species of birds. Metadata for the BBS data used to produce these estimates is available from a USGS ftp site (ftp://ftpext.usgs.gov/pub/er/md/laurel/BBS/DataFiles/). Metadata associated with this data product provides information specific to the analysis results.

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 Latitude is the average latitude of all 0.5 degree cells covering the eastern United States and southeastern Canada between longitude 60W and 102 W and latitude 24N and 49N, weighted by the unconditional probability of occupancy of Louisiana Waterthrush. Values given for the years 1997 to 2013. The Latitude_SE is the estimated standard error for the Latitude. Description of the data and analysis used to generate these values is given in: Clement, M.J., J.E. Hines, J.D. Nichols, K.L. Pardieck, D.J. Ziolkowski Jr. 2016. Estimating indices of range shifts in birds using dynamic models when detection is imperfect. Global Change Biology 22:3273-3285. doi: 10.1111/gcb.13283.
