YOUNGLING VERVET MONKEY - Tarangire National Park, Tanzania.

Take a look at the closest limb and you'll see a VERVET MONKEY sitting atop. But also look to the background for another one in the tree behind it. From the series "Into Africa"

THE CUDDLE.  Lots of debate out there about the differences between blue and Syke's monkey, but one thing I found is that many people use these names interchangeably, despite disputes.  Blue monkeys do live in the evergreen, canopied forests and I saw many during my visit to Arusha National Park.  Grooming and cuddling is a major part of their social interaction.
