The Common Yellowthroat Genoscape. The top panel depicts the STRUCTURE analysis with each line representing the posterior probability of assignment of each individual belonging to one five genetic groups. Numbers indicate the locations of sampling sites on the map. The bottom panel depicts a spatially explicit map of population structure clipped to the breeding range (eBird 2021), with the intensity of color representing the certainty in the assignment of individuals from a particular region belonging to a genetic group. Circles on the wintering represent sampled individuals color coded by the genetic assignments according to rubius. The wintering dots are jittered to facilitate visualization.
