Range Description

This species is restricted to the western Andes of Colombia, and is found where the departments of Chocó, Antioquia and Risaralda meet, in Munchique massif (Valle de Cauca) (Kroodsma and Brewer 2005), in extreme eastern Chocó and south-west Antioquia department, and in extreme south-eastern Chocó near the town of El Cairo where a population of at least 5 individuals was discovered in 2008 (van Oosten and Cortes 2009). It appears to have very specific habitat requirements, being restricted to the Pacific slope of the very peaks of the highest mountains/ridges on the Western Cordillera. The Western Cordillera is the lowest and narrowest of Colombia's three Andean ranges (T. Donegan in litt. 2006). As a result this species's global area of occupancy is tiny. A total of 5-8 territorial pairs or males were registered along a 2-km transect (equating to 10-16 pairs per km2). This represents a much lower density than parapatric populations of Grey-breasted Wood-wren (c.10-14 territorial pairs per 2 km transect) (P. Saraman in litt. 2006, T. Donegan in litt. 2006). Extrapolating the estimated population density across the known range gives a population estimate of 180-288 pairs (P. Salaman in litt. 2006). This extremely small population is likely to be declining owing to ongoing forest clearance. There have been many surveys of the high peaks along the Western Cordillera (both historically and in the past decade) that have failed to record this species, suggesting there are unlikely to be many undiscovered populations remaining (P. Salaman in litt. 2006).
