Figure 1. The population structure on the breeding range is delineated by five genetically distinct clusters (colored polygons) from the results of the admixture analysis (top panel). Population structure was determined using 169 individuals from 16 sites (black points) on the breeding range. Individuals sampled from the non-breeding range were determined to originate from a given breeding population through population assignment tests (n = 138; colored circles). The point colors on the nonbreeding range represent the breeding population of maximum likelihood of assignment and the extent of the nonbreeding range is provided by the grey polygon. Strong migratory connectivity is evident from the general separation of breeding population assignment across the wintering range.
