I was really hoping to encounter some Colobus monkeys having read about them in a description of the Rongai trail. Although our guides were really good at spotting wildlife for us, it was I who heard a rustling in the trees and paused long enough to identify the source. The reward was a great opportunity to photograph three monkeys. Unfortuantely, I was unable to get a good shot including their massive white tails which exceed their body size in length. These creatures are absolutely spectacular.
