Leptasthenura xenothorax has a very restricted and severely fragmented range in the Runtacocha highland (Apurmac), the Nevado Sacsarayoc massif and the Cordillera Vilcanota (Cuzco), south-central
Peru. Significant populations of c.35-70 individuals were estimated at three sites in Cuzco in 1987-1989, but declines have been observed at some of these, and the population density is very low in the Runtacocha highland (Fjelds and Kessler 1996). The patchiness and scarcity of its habitat, which may now occupy less than 3% of the estimated potential cover in large parts of Cuzco (Fjelds and Kessler 1996), suggests that the total population must now be very small (Fjelds and Krabbe 1990), with one recent estimate of 500-1,500 individuals (Engblom
et al. 2002)
