The Marsh Wrens that breed in salt marsh on Florida's Gulf Coast are a different subspecies ("Marian's" Marsh Wren, Cistothorus palustris marianae) than the Marsh Wrens that winter in coastal salt marsh or freshwater marsh in Florida's interior, including the Everglades. Another subspecies, "Worthington's" Marsh Wren (C.p. griseus), breeds in salt marsh on the southern Atlantic coast to north Florida. These two subspecies are believed to be non-migratory. The subspecies that winter in Florida, but breed elsewhere include C.p. palustris, C.p. thryophilus, C.p. dissaeptus and C.p. iliacus. These subspecies arrive in Florida beginning in September and leave by May. Thus, any Marsh Wren found in the Everglades in July would be a significant deviation from what is currently known .
