little people with tails

The monkeys around here are prolific, mostly little reddish brown ones. While walking through the streets, we got a chance to see some up very close. Here is a mama and baby from about five feet a

way. We didn't see many of this species. When we asked the waiter last night what kind of monkeys were all around, he told us "monkeys are like little humans, with two hands and two feet but a very long tail." We palyed along. We still don't know what species they are.
