(Troglodytes troglodytes), a bird of the family Troglodytidae of the order Passeriformes. The body length measures 10−12 cm long; the bird weighs 8–11 g. The plumage is grayish brown.
The wren is distributed in Europe, North Africa, Asia, and North America. In the USSR it is found from the western borders to the Kuril Islands (except Western and Central Siberia). In the northern part of its area of distribution it is a migratory bird, while in the south it is not. The wren stays in coniferous and leafy forests in dense underbrush. In the mountains of Middle Asia and on the Komandorskie and Kuril islands it is found on cliffs and in sparse thickets. The nest is globular, with a side entrance. The clutch contains six or seven eggs, which are white with reddish spots. The wren incubates the eggs 14–15 days. It feeds primarily on spiders and small insects; it also eats seeds and berries.
