n.
Any of 59 species (family Troglodytidae) of chunky songbirds, found in the Western Hemisphere.
One species, Troglodytes troglodytes , has spread to the Old World; typical of the family, it is about 4 in. (10 cm) long and dark-barred brown, with a short, slightly downcurved bill, short rounded wings, and short cocked tail. Common throughout the Western Hemisphere is the house wren. The largest U.S. species (8 in., or 20 cm, long) is the cactus wren of southwestern deserts. Wrens hunt insects in marshes, rocky wastes, or shrubbery, revealing their presence by chatter and loud song. They nest in holes, in thickets, or on ledges.
