Range Description

Troglodytes monticola is endemic to the Sierra Nevada de Santa Marta, Colombia, where it is known from collections made in 1922, one record in the upper ro Fro Valley at 3,600 m, where a pair was observed and tape-recorded in a small montane forest patch (c. 2 ha) amidst heavily burned and overgrazed pramo (R. Strewe in litt. 2003), and 17 individuals located in a targeted search in 2011 (Luna and Quevedo 2012). Searches on the southern slopes and at the only other intact forest patch in the area failed to locate the species (R. Strewe in litt. 2003, Fundacin ProAves de Colombia 2011), however in December 2011 the species was photographed for the first time and a total of 17 individuals were observed in three days along a 3 km stretch (Luna and Quevedo 2012). Several pairs of the species were sighted recently during fire surveys in the Parque Nacional Natural Sierra Nevada de Santa Marta (Rojas and Vasquez 2015). The lack of recent reports may partly reflect the fact that the species is not found in the only area of the Santa Marta massif regularly visited (Ridgely and Tudor 1989).

Habitat and Ecology
The species is reportedly found in low, thick shrubbery at the timberline and in sheltered spots high in the pramo zone, from 3,200 to 4,600 m (Ridgely and Tudor 1989). It may actually be restricted to the timberline ecotone, rather than being a pramo specialist (Fundacin ProAves de Colombia 2011).

Justification
This species is considered Critically Endangered because it is suspected that it will undergo an extremely rapid decline over the next three generations. It is thought to have experienced a very rapid decline over the last three generations, as its habitats continue to be extensively cleared and heavily degraded in its very small range, in which it is known from only one location.
