House Wrens occupy the northern two-thirds of the United States and parts of Canada. They breed in forest edges, shrub lands, swamps, fields, farmlands and suburban parks. The breeding season begins in late April for birds living in the southern portion of their range; it begins in early May in the northern portion. House Wrens nest in natural cavities, tree stumps, woodpecker holes, building nooks and crannies, and in nest boxes. They have also been known to nest in such unique places as cow skulls, flower pots, tin cans, boots, scarecrows, and the pockets of hanging laundry. The male arrives first on the breeding territory. Males return to the same breeding territory year after year. Once he establishes a territory, he builds "dummy nests" in all available cavities on his territory. When the female arrives, she selects a nest site that may or may not be one of the nests started by the male. House Wren nest boxes should be mounted 5 to 10 feet high near trees or tall shrubs.

Carolina Wrens are commonly found in the southeastern United States. These shy wrens require dense shrub and brushy habitats for concealment. As a result, they are more often heard than seen. They are common in forests, clear cuts, and wooded suburban areas with thick underbrush. They prefer moist bottomland forests and swamps over dry upland woods. Carolina Wrens begin breeding as early as mid-March in some regions, in early April in others. Males build multiple nests within the territory, but females select the final nest site. Nests are usually built in enclosed areas: natural cavities, vine tangles, upturned roots, tree stumps, or abandoned woodpecker holes. They also nest in nest boxes and other, less-natural nooks and crannies such as mailboxes, glove compartments, tin cans, and old shoes. Carolina Wren houses should be mounted 5 to 10 feet high near trees or tall shrubs.
