The plain-tailed wren (Pheugopedius euophrys) is a species of songbird in the family Troglodytidae. It has a mostly rufous body with a gray, black, and white striped head. It is found in the Andes of southern Colombia, Ecuador, and northern Peru. Its natural habitat is subtropical or tropical moist montane forests. Plain-tailed wrens are so-called bamboo specialists and live almost exclusively in chusquea bamboo thickets. Like other wrens, its diet consists mainly of insects with some seeds and berries.
Taxonomy
The plain-tailed wren belongs to the order Passeriformes and the family Troglodytidae. Three subspecies are recognised:
P. e. euophrys (Sclater, PL, 1860) – southwest Colombia and west Ecuador
P. e. longipes (Allen, JA, 1889) – central east Ecuador
P. e. atriceps Chapman, 1924 – north Peru north of the Río Marañón
The grey-browed wren was formerly considered as a subspecies but is now treated as a separate species based on the distinctive vocalizations and some morphological differences.
