Out on a game drive in Ol Pejeta Conservancy, I came across a herd of Reticulated Giraffes. When these animals finish drinking, they flick their head and a dribble comes out of their mouth. I waited for the giraffe to start raising its head at the water hole and took a series of pictures. What I did not foresee was the oxpeckers flying away.
