Weeper capuchin

Si es de Puerto Ordaz entonces es Cebus Apella Apella

I think all three are same specie. Caroline, your spotting also have Reddish hair on back as I feel. Face is also Pinkish, but not acknowledged due to light and different angle you got.

Diogenes, I'm 99% sure these spottings are the same primate:

You can upload those pictures in this spotting, so we can see the 3 pictures together, do you know how to this? If you don't let me know.

Also, looking at those pictures I'm pretty sure it is a Weeper capuchin :)

Hola Carolina, si tengo algunas otras fotos, las voy a poner.

Diogenes, tienes otra foto de este primate?

Carolina, I think you have almost reached...!!
I think its a young one so not easy to match..!!

I must say a Weeper capuchin (Cebus olivaceus), but still not sure.

I'm not sure about a spider monkey...

Looks alike..Spider Monkey
