Despite their size difference, African Buffalos and Oxpeckers have formed a convenient symbiotic relationship. The Buffalos tolerate the Oxpeckers because they help to remove bothersome ticks.
The Oxpeckers get to enjoy both a tick meal as well as opportunistic snacks provided by the numerous flies that frequent the Buffalo. The Buffalo are quite skittish and rarely stay still for long.
The Oxpeckers will often hop around the Buffalos’ faces, but they are in a constant state of motion and the Buffalo will shake them off if they linger on any one spot.
In short, it is not that easy to make a good image of an Oxpecker on a Buffalo face, but here I think I have managed it, capturing the moment that the Oxpecker was hopping from the nose to the head. I wanted the side profile to give the impression of the Buffalo watching and even begrudgingly greeting its unlikely partner.
