Great Plains grassland bird abundance trends

Of all bird guilds in North America, grassland birds have experienced the sharpest declines since 1970. Here, we use the bbsBayes R package to estimate abundance of 50 species of grassland birds from 1984 - 2019 in the Plains states. To run these analyses, open the "GreatPlainsBirds.RProj" file, open the "GreatPlainsBirds_Analysis.R" script file, and run this script. NOTE: Running the abundance models can take days or weeks of runtime.
