The amount of potential Bicknell’s Thrush habitat (km2) in protected and unprotected areas estimated from the most parsimonious Maxent model (land cover, wprecip, aspect, slope, and elev).

We used the 10 percentile training presence logistic threshold (0.248) to create a distribution map of potential Bicknell’s Thrush winter habitat. The Nature Conservancy provided up-to-date protected areas boundaries for our study area. We used both officially designated and newly proposed protected areas for our analysis as a best-case scenario.
