Abstract (from https://www.ncbi.nlm.nih.gov/pubmed/26990459): There is intense interest in basic and applied ecology about the effect of global change on current and future species distributions. Projections based on widely used static modeling methods implicitly assume that species are in equilibrium with the environment and that detection during surveys is perfect. We used multiseason correlated detection occupancy models, which avoid these assumptions, to relate climate data to distributional shifts of Louisiana Waterthrush in the North American Breeding Bird Survey (BBS) data. We summarized these shifts with indices of range size and position and compared them to the same indices obtained using more basic modeling...

This data product provides summary information of changes in relative visibility of 408 species of North American birds (phenology effects) through the April - July time period in which the North American Breeding Bird Survey (BBS) is conducted. These phenology effects are presented for selected latitudes and years, documenting changes in visibility and a variety of statistics to allow users to assess the significance of those effects. Results are presented as R data sets as supplemental material to primary results presented as csv files.

These data indicate the modeled density of greater sage grouse for 75% of birds in 26.9% of their overall range. This dataset was provided by BLM with minimal metadata.

This data product provides summary information, by species, of changes in relative visibility of birds (phenology effects) through the April - July time period in which the North American Breeding Bird Survey (BBS) is conducted. Data are presented for 408 species of birds. Seasonal phenology effects are presented for selected latitudes and years, documenting changes in visibility and a variety of statistics to allow users to assess the significance of those effects. This Child Item is a supplement to the Sciencebase Data Release "Phenology effects in the North American Breeding Bird Survey," in which the results are presented in summarized graphical form in species-specific pdf files.

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.

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.
