We only saw one lone monkey scurry down a branch in the shadows of a tree in Costa Rica but in Nicaragua we saw a number of them…2 kinds.
The first group was on the Islet Tour in Lake Nicaragua near Granada. There are 365 islets (big enough for at least a house if not more) formed from the eruption of a volcano long ago. One of those islets has 4 spider monkeys.
The monkeys are quite used to tourists in the boats coming and feeding them so they are easy to see. We did an afternoon tour so they weren’t hungry (and we didn’t know to bring fruit for them anyway) but I understand that during morning tours they are even more visible.
The second group was at Charo Verde Reserve on Ometepe Island. Those were Howler monkeys and I’m not sure how many we saw, at least a half dozen. They were above us in the mango trees, taking a bite out of the fruit and throwing it down to the ground (reminded me of the squirrels and our peach trees at the house in San Antonio.
The monkey we have seen the most of is Mona the Common Marmoset at Finca Soley. She gets her own posting.
