Description: For each suitable radar sampling day, we used instantaneous measures of vertically-integrated radar reflectivity (VIR; the relative emigrant density in the air from the ground to 1.5 km above ground) interpolated in time to the peak of bird nocturnal flight exodus to map relative emigrant bird stopover densities. We classified bird stopover use by the seasonal mean emigrant density (mean VIR) and coefficient of variation of emigrant density (CV VIR) to identify areas of consistently-high emigrant density. Radars provided direct comprehensive observations of the spatio-temporal patterns of stopover use of migrating birds across nearly a quarter of the land area within the state of North Carolina.
