Monkey Island
Hola Señora Habs :)
It looks like you have 2 different species here and a subspecie. The gray one looks like a Monk saki (Pithecia monachus), and the one in the left like a White-tailed titi (Callicebus cupreus discolor), and the one in the bottom like a Callicebus cupreus. But I'm not quite sure, I'd like someone else reviewing this information first.
