A medium sized monkey that travels the forest in groups of 5-20, from what I've seen. They have black fur except for on their face, shoulders and upper chest, which are white.
These were in seasonally dry tropical forest in the Lomas Barbudal Biological Reserve. But they seem to be found in most forests across the country.
I spotted these monkeys from a bit of a distance and sat down on a rock about 20m away. They slowly worked their way towards me till they were almost right in front of me. One walked by within reaching distance. I've never seen wild monkeys so at ease with a person. I suspect they must be used to people around them.
