As the furry mammals wander the park, they pick up all sorts of fleas, ticks and other creepy crawlies. The best way for them to be ridded of such pests comes in the form of the Red-billed Oxpeckers. They fly from Giraffe, to Impala, to Rino, to Cape Buffalo, doing a cleaning service for whoever needs it. They are not bashful, climbing in to any orifice that might contain a bug of some form. Ears, noses, and even backsides all get thoroughly checked.
