Zaratornis stresemanni is patchily distributed in the Cordillera Occidental of the Andes in Peru (La Libertad, Ancash, Lima and Ayacucho), with most records on the west slope. It has been observed at Tayabamba, La Libertad, in the Cordillera Central, where it may be resident, seasonal or vagrant. A recent observation at El Molino, also in La Libertad, suggests its range may be greater than previously thought (F. Angulo Pratolongo in litt. 2012). It is common north of OyÃ³n, with an estimated 500 birds in this district (FjeldsÃ¥ and Kessler 1996); in the Cordillera Huayhuash area (Maynard and Waterton 1998), and in the upper Santa Eulalia Valley, where it numbers upwards of 250 birds (Maynard and Waterton 1998, G. Servat in litt. 1999). It is also fairly common in parts of the rÃo CaÃ±ete drainage, Lima (FjeldsÃ¥ and Kessler 1996, Maynard and Waterton 1998, G. Servat in litt. 1999). In 1992, the population was estimated at c.3,000 individuals; actual numbers are probably between 1,500 and 6,000.
