I photographed a few of these guys in the Falklands and then saw them again on this most recent trip to Patagonia. This one was spotted just north of Punta Arenas, Chile on our way to Torres Del Paine. A bit of a rear view here, but the entire breast is that red color that you see on the face.

This pair of gray foxes were taking a morning rest in Torres Del Paine. We would see them again later that morning, attempting to grab all they could of a puma’s kill before the rightful owner returned to claim her property.

As soon as I saw this puma about to make a run at a group of guanacos, I quickly lowered the shutter speed of my camera by closing down the aperture, and I steadily tracked along with her. Unfortunately for the puma, her effort went unrewarded as the faster guanacos all got away. As for me, I was able to caputure a nice series of motion blurred images. I’ll post a few of the others in the future.

Meet the lesser rhea, otherwise known as Darwin’s rhea. Also otherwise known as the flightless bird they make feather dusters out of. In addition to their feathers, they are also farmed for their meat and eggs, their hide for leather and their oil for cosmetics. Needless to say, they have become near threatened in much of their range. Within Torres Del Paine, they are protected, at least from humans. Pumas will hunt them to add variety to their guanaco-rich diet. Rheas are related to the emu and are one of the world’s four large flightless birds along with the cassowary and the ostrich (there are other flightless birds in the world, but those four are the big boys).

I previously posted this mother and also posted the cub. Here they are together, traveling along a lake in Torres Del Paine National Park. A few yards back and out of frame were two other cubs. Shortly after taking this photo, I turned my attention to an owl that was behind me. When I looked back, I had lost site of the pumas, but at least I got a few shots of them on the move after an afternoon of rest.

The great thing about guanacos is that they were seemingly everywhere in Torres Del Paine. When the light was good, it didn’t take long to find one — or two in this case — up on some ridge top with dramatic mountains and clouds in the background.

I watched this puma stalking, and then half-heartedly chasing, a herd of guanacos. It almost seemed as if she knew she had no chance but was going to give it a go anyway just in case. After all her would-be victims disappeared over the horizon, she plopped down for a nap. I’ll post some of the stalking pics soon.

The two photos making up this gif are of the same crested duck, taken from the same spot. But as the duck moved slightly, those colorful feathers on the back side changed from a maroonish to a deep green and then back again. They’re called the speculum feathers. Many ducks have them and they are often iridescent, allowing changes in color based on wing position, angle of view and lighting conditions.

With all the spectacular scenery in Torres Del Paine, it was tough not really having the time to get proper landscape shots. The hours of best light were spent tracking pumas so I had to grab landscapes where and when I could. Usually I would never shoot in the middle of the day like this, but with a polarizing filter, plus a 3 stop neutral density filter, and a bit of cloud cover, I was able to slow down the shutter enough to make this view of a waterfall interesting. In the background is the Cordillera Paine, the centerpiece grouping of towers, horns and peaks that give the park its name.

The European hare is a non-native species in Patagonia. Quite often, introduced species wreak havoc on their new environment, but in the case of this guy, all seems fine — at least in Torres Del Paine National Park (I’ve read of problems elsewhere where they cause damage to orchards, plantations, etc, and compete for grazing with cattle). But in the park, European hares add a bit of variety to the diet of pumas and don’t appear to have any ill effect on native species of fauna or flora. They are mostly nocturnal and were all over the front lawn of our lodge at night, but I was able to photograph this guy in the last light of the day.
