The Culpeo (Lycalopex culpaeus), sometimes known as the Culpeo zorro or Andean fox (wolf), is a South American species of wild dog.
This female was busy nursing pups somewhere close. She was very weary of our presence, but the 400mm lens meant I could photograph her and keep my distance. This fox was photographed in the Torres del Paine National Park in Patagonia, Chile. Wildlife photography is all about making the best of a situation you find yourself in.
Sometimes lugging all that heavy camera gear proves worthwhile.
