Guianan Squirrel Monkey, GuyanaThese squirrel monkeys were daily visitors to the mango trees in the backyard of the lodge I was staying at in Guyana. They are appropriately named as they really are about the size of a common grey squirrel. Nikon Z8 with Nikkor 500mm PF lens, ISO 1800, f/5.6 at 1/500th of a second.
