Via USGS news release, includes data files and photos :”Species distribution modeling was used to assess the relative impacts of climate and land-use change on fifty bird species for the conterminous United States. Species presence data, current and projected land-cover data, current and projected climate data, and topographic data were used in a maximum entropy modeling framework to assess impacts of climate and land-cover on bird distributions for 2001, and for multiple 2075 scenarios. The following provides access to output data for this assessment, including:

1. Output range maps for 2001 and 2075 for each of the fifty modeled species
2. Images (maps) of the predictor variables (covariates) used to construct the species models
3. Comprehensive spreadsheet providing quantitative output results reported in the accompanying paper.
