C. chinchilla was recently recorded in pellets from Bubo magellanicus in the province of Salta (Ortiz et al 2010; Fig. 1.). Camera trapping efforts from 2011 registered a C. chinchilla colony at Parque Nacional Nevado Tres Cruces, a second colony was detected further north in Santa Rosa, the northern area of the park. The species appears to be more common than originally thought (Augustin Iriate Walton pers. comm.).
