The upper parts are rufous brown, and the underparts a strong orange-buff, usually unmarked but faintly barred on the flanks in the southwest of the range. The head has a striking pure white supercilium (eyebrow) and a whitish throat.
Their preferred habitat is in dense cover in forests, farm edges and suburban areas. This wren is the state bird of South Carolina. The Carolina Wren is sensitive to cold weather. Since they do not migrate and stay in one territory the northern populations of Carolina wrens decrease markedly after severe winters.
