Résumé :	We analyzed 2426 records of recoveries of banded House Wrens (Troglodytes aedon) to identify wintering sites of individuals coming from different parts of this species' broad North American breeding range. Records suggest that most birds breeding approximately east of the Appalachian Mountains (n = 6) winter in the far southeastern United States, especially Florida. In contrast, birds breeding west of the Appalachian Mountains (n = 23) into the eastern Great Plains may winter anywhere from South Carolina and Florida west into Texas. It also appears that individuals from the same breeding populations winter in different sites. The few recoveries (n = 4) of birds from breeding sites on the western Great Plains indicate that at least some individuals from this region travel not due south but rather southeast during migration and winter in the eastern half of the southern U.S. No long-distance recoveries have been made of birds from breeding in or west of the Rocky Mountains.
