Chilla (Lycalopex griseus)

There are two similar looking foxes found on the Patagonian Steppe. This is the smaller more common Chilla posing at the entrance to its den. It differs from the larger Culpeo (Lycalopex culpaeus) in having distinct dark patches on its hind legs, and longer more closely spaced ears. It is sometimes called South American Gray Fox. This is presumably the nominate most southerly subspecies. Some West Coast populations were originally included with the similar Pampas Fox. Formerly placed in the genus "Pseudalopex."
