Moving on to South America (Argentina, specifically) and "foxes" - the variability makes it a killer problem and everywhere there are at least two species in range:
C1: Near Salinas Grandes, NW of Cordoba: Pampas and SA Gray possible
C2: Sierra de las Quijadas, San Luis: Pampas and SA Gray possible
C3-4: Ushuaia, Tierra del Fuego: Andean and SA Gray possible
C5: Malargue, Mendoza: Andean and SA Gray possible
Birds: world 1974, WP 561 (#1 Czech WP birder!*)
* and my wife is #3
