Tepui Wren is a small Troglodytes wren of southern Venezuela and adjacent Brazil and Guyana. Like many other unique species of the region, the wren is geographically restricted to its namesake tepuis, the massive table-top mountains that are isolated in northern South America away from the Andes. Due in part to ancient sandstone connections to other highlands on the continent that have largely eroded away, the tepuis are havens for biological endemism. Specifically, Tepui Wren favors edge habitats from 1000-2800 meters in elevation. It is similar to the Mountain Wren in appearance, and is dark rufous brown above and paler brown below with black barring on the wings and tail and a buffy supercilium. The song of the Tepui Wren, a rapid jumble of high pitched notes, is useful for locating this secretive species that skulks around on the ground.
