Grass Wren

The Grass Wren occurs in high-elevation habitats across the Ecuadorian Andes, typically between 2,800 and 4,200 meters, where it inhabits páramo grasslands, marshy meadows, and shrubby edges. It is generally uncommon but locally present, often detected by its sharp, trilling song as it forages low in dense vegetation for insects and spiders. The species is listed as Least Concern by the IUCN, with a broad South American range and a stable population, though it may be sensitive to habitat degradation from grazing and fire. Natural history observations highlight its cryptic plumage, dome-shaped nests hidden in grass tussocks, and strong site fidelity, with breeding timed to coincide with the rainy season.
