Woolly Monkey, PeruHere’s another look at the woolly monkey I photographed in Peru. There are two species and 5 subspecies of woolly monkey. I got many frame-filling shots of this guy, but I always seem to prefer the images when I go a bit wider and include the environment. You can see the use of that prehensile tail acting like a third arm as he swings through the forest. Nikon D500 with Nikkor 500mm PF lens, ISO 1250, f/4 at 1/800th of a second.
