Our objective was to determine whether there were subpopulations within the eastern population of tundra swans ( Cygnus columbianus columbianus ) wintering along the mid‐Atlantic coast. Movement rates between regions were substantial enough to result in continual mixing of wintering birds. Thus, we were unable to identify distinct subpopulations based on exclusive use of specific wintering areas. These birds should therefore be monitored, and their harvest managed, as if they were one population.
