Language: French; Spanish

Wikipedia Abstract

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. 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 forests, farm edges and suburban areas.
