Résumé :	ABSTRACT Midwest breeding populations of the eastern North American Marsh Wren (Cistothorus p. palustris) perform intra-summer movements presumably to breed at two different locations during the same summer. It appears that birds that initially breed during May-June move south to breed again during mid-July through August. Because this unique behavior is shared with its closest living relative, the North American Sedge Wren (C. platensis stellaris), it may be an ancestral trait of Cistothorus.
