Pygmy Marmoset, PeruOn my first trip to Iquitos, my main target was the world’s smallest monkey, the pygmy marmoset. I got lots of images so wasn’t concentrating on them on this recent trip. That said, I did make a few visits to areas they’re known to frequent. They love to eat tree sap, which this guy was doing when he took a look around while licking his chops.
