When on the ground, they move in jerky hops pillaging through various objects, whether man-made or natural.
Carolina wrens are wary and are more often heard than seen. They also probe bark crevices on lower tree levels or pick up leaf-litter in order to search for prey. Some populations have been affected by mercury contamination.Ĭarolina wrens are active during the day and spend the majority of their time on or near the ground searching for food, or in tangles of vegetation and vines. Carolina wrens raise multiple broods during the summer breeding season, but can fall victim to brood parasitism by brown-headed cowbirds, among other species. Both males and females give out alarm calls, but only males sing to advertise territory. After finding a mate, pairs maintain a territory and stay together for several years. When out in the open, they investigate their surroundings and are rarely stationary. The birds are generally inconspicuous, avoiding the open for extended periods of time. There are seven recognized subspecies across the range of these wrens and they differ slightly in song and appearance. This wren is the state bird of South Carolina. Their preferred habitat is in dense cover in forest, farm edges and suburban areas. Severe winters restrict the northern limits of their range while favorable weather conditions lead to a northward extension of their breeding range. The Carolina wren ( Thryothorus ludovicianus ) is a common species of wren that is a resident in the eastern half of the United States of America, the extreme south of Ontario, Canada, and the extreme northeast of Mexico.
