I was in the Selva Maya of Quintana Roo putting dendrometer bands around some of the timber trees to measure growth (see Selva Maya III). There were monkeys (Ateles geoffroyi yucatanensis) jumping around in the canopy and making a lot of noise and one landed very close to me and was checking me out. I tried to get a picture, but my camera focused on the leaves in the foreground, not the monkey in the background. [NOTE: I hate it when that happens].
