Plain-tailed Wren

The Plain-tailed Wren occurs along both slopes of the Ecuadorian Andes, where it inhabits dense Chusquea bamboo thickets within humid montane forests typically between 2,200 and 3,400 meters. It is generally uncommon but locally present, often detected by its rich, antiphonal duet singing, with pairs weaving through tangled understory as they forage for insects. The species is listed as Least Concern by the IUCN, with a broad Andean range and a stable population, though its strong dependence on bamboo makes it vulnerable to habitat disturbance. Natural history observations highlight its cooperative vocal behavior, cryptic plumage, and specialized foraging techniques, while nesting biology in Ecuador remains lightly documented.
