Land cover and NDVI are important predictors in habitat selection along migration for the Golden-crowned Sparrow, a temperate-zone migrating songbird

The minimum (min), maximum (max), mean and standard deviation (SD) of environmental data values extracted across all presence (p) and random (r) locations. Environmental values include NDVI, daily precipitation (mm; Precip), maximum daily temperature (°C; Max Temp) and minimum daily temperature (°C; Min Temp) at known stopover (p, n = 233 for fall and n = 287 for spring) and random (r, n = 4660 for spring and n = 5740 for fall) locations for spring and fall migration
