A pair bond may form between a male and a female at any time of the year, and the pair will stay together for life. Members of a pair stay together on their territory year-round, and forage and move around the territory together.
Near homes, they’re versatile nesters, making use of discarded flowerpots, mailboxes, propane-tank covers, and a variety of other items. Their nests have even been found in old coat pockets and boots. Males often build multiple nest starts, and the female makes the final selection.
Male and female Carolina Wrens complete the nest together. One member of the pair may stay at the site while the other gathers material.
