Not labelled with a species but looks like [i]Saimiri boliviensis[/i] - a single animal that may have been an ex-pet.
This is the Grand Canyon Deer Farm, Williams, Arizona. Not a famous or spectacular place, but we'd had several excellent roadside views of Mule Deer and Pronghorn without being able to take any photos for various reasons (car surrounded by Pronghorns and the cameras in the boot being the most annoying!) so 14-year-old me convinced parents to call in here so I could get some shots. Which I did, after a fashion.
