The Carolina wren (Thryothorus ludovicianus) is a species of wren common in the eastern United States, the extreme south of Ontario, Canada, the northeast and southeast of Mexico, and into northern Central America. Severe winters restrict the northern limits of their range, while favorable weather conditions lead to a northward extension of their breeding range. Their preferred habitat is in dense cover in forest, farm edges, and suburban areas. This wren is the state bird of South Carolina.
Ten subspecies are recognized, occurring across the range of the species; they differ slightly in song and appearance. It is generally inconspicuous, avoiding the open for extended periods of time. When out in the open, they energetically investigate their surroundings and are rarely stationary. After finding a mate, pairs maintain a territory and stay together for several years. Both males and females give out alarm calls, but only males sing to advertise territory. Carolina wrens raise multiple broods during the summer breeding season but can fall victim to brood parasitism by brown-headed cowbirds, among other species.

GBIF citizen-science records
It is estimated from how often the Carolina Wren is recorded against all the birds logged in Merritt Island National Wildlife Refuge (2,696 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
