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.
