Who is this?

We are deeply into our mango season and that means visitors from the forest. There are some 600 mature mango trees on this property. The wild monkeys come to our compound seeking mature mango fruit. But also get involved with our residents. Early in the season we had unwelcome Capuchin visitors that attacked and injured Pancho. I reported that in an earlier post.
Yesterday was a different story. We had a visit from a young adult Howler. He has been good mannered, centering his interest above the enclosure of MonaLisa, Emma and Nancy. He obviously has an eye for the girls. He is young and very hansom. Unfortunately our photograph does not really do him justice. The telephoto ability of small digital cameras is not good. He remained in a tree above their enclosure overnight, joining in the evening and early morning chorus. This is a recurring phenomenon. Often we get a male and alongside him a small female visitor. I have the impression that it has been the same monkey for a few years now although I do not recognize our recent visitor. He is a new comer.
I would like to welcome him but my fears about transmitted disease from the forest prevent me from feeding him or encouraging him.
