Troglodytes is a genus of small passerine birds in the wren family.These wrens are around 11–13 centimetres (4.3–5.1 in) long. They are brownish above and somewhat paler below, with strong legs. Their short rounded wings and frequently cocked tail have a dark barred pattern. The flight is direct and buzzing. Like other wrens, they are elusive as they hunt for small insects and spiders, but they readily reveal their positions through their loud songs. These are territorial birds, but the tiny winter wren will roost communally in a cavity in cold weather to help conserve heat.
