The Carolina wren is an adaptable dweller of forest lands, swamps, farms, and tree-filled human communities. Carolina wrens are small but very vocal animals. Males are especially outgoing and are the only ones to produce songs. They employ one of the loudest songs per volume of birds. They are apt to sing anytime and anyplace they happen to be. Carolina wrens are usually found in pairs, and each pair stays on its home territory all year long.
