Yellow-billed Oxpecker

We were driving along a backroad when this giant giraffe walked into the street. I had too much lens to capture after the animal, so I turned my lens on this hitchhiker as he pecked at the beast's leg. The bird isn't hurting the giraffe; he's grooming the animal and removing (i.e. eating) ticks and other parasites. So, its a win for both.
