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.本研究采用训练存在记录10%分位数逻辑回归阈值（0.248），绘制了比克内尔鸫（Bicknell’s Thrush）的潜在越冬栖息地分布图。大自然保护协会为本研究区域提供了最新的保护区边界数据，本分析纳入正式划定与新申报的保护区，以构建最优情景假设。
