A Patagonian grey fox looks up to survey the situation, making sure that a puma isn’t about to come back and lay claim to a guanaco carcass, Torres Del Paine National Park in Chile.

I’ll admit, I was a bit nervous when this Patagonian hog-nosed skunk got up on its hind legs to sniff the air. It was bothered no doubt, by a particular camera-carrying American. I remained as still as possible (snapping away of course) until the skunk regained its confidence and resumed the serious task of eating grass.

When flamingos take off from the water it can look like they’re running across the surface. This guy decided it was time for a new location and allowed me a series of images as he/she took to the air.

A puma makes her way to a watering hole for a quick drink before continuing on to a kill she had hidden in the grass. Torres Del Paine National Park in Chilean Patagonia.

My guide and I had to climb pretty high up a steep slope to capture images of this puma surveying her territory. She eventually spotted a small group of guanacos and made an unsuccessful run down the hill. I was hoping to get her positioned on the ridge line, but that wasn’t to be. Fortunately, however, my high vantage point did enable me to capture the distant snow capped mountains in the backdrop, giving a sense of the Patagonian landscape in which these amazing cats thrive. Being springtime for us, it was fall for the southern hemisphere and you can see all the rust-colored leaves dotting the mountainsides.

As I mentioned recently, guanacos can be great subjects, especially when framed within the landscape of Torres Del Paine in Patagonian Chile. The early morning light was hitting these two with direct light while the massive face of that mountain in the background was in shadow, and partially obscured by fog and clouds.

This puma was moving stealthily below a ridge, out of sight of the guanaco up on the hill. Eventually the guanaco caught wind of the puma and made a dash for it in the other direction. The puma, unfazed, continued on her way, as she had already made a kill and was on her way back to it for dinner. Pumas, however, are opportunistic hunters and had the guanaco been completely fooled, there would most likely have been an attempt at a second kill.

I saw lots of these raptors in Chile. This is the southern crested caracara, formerly thought to be the same species as the northern crested caracara. The northern species ranges as far north as the extreme southern portions of the US, whereas this guy can be found from mid Brazil on down to the tip of South America. For this image, I was able to capture a bit of the fall colors — in the top third of the frame — that defined much of the landscape en route to Torres Del Paine.

As I mentioned previously, the guanacos on my Chilean trip were great subjects due to their iconic shape and the fact that they were so ubiquitous throughout Torres Del Paine National Park. I photographed this one late in the day while waiting for the puma that I posted on Monday to get back to her kill.

We tracked this puma for about half a mile as she slowly made her way back to a kill that she had hidden in the grass earlier in the day, or perhaps the night before. She got a bit ahead of me, but I was still able to get a few of Torres Del Paine’s majestic peaks in the background.
