Border Dispute - two black rhinos fight over their territory in Nairobi National Park. On a particularly busy morning in the Park, I drove off in the most random direction and came across these two fighting each other no holds bared. The one on the right, clearly exhausted, was playing the defensive and was getting the worse of it, with bright red blood dripping down from a wound in his chest. After an hour of this back and forth and for no particular reason I can comprehend, the aggressive rhino stopped, turned around and walked off into the distance, leaving the “survivor” in the middle of the road, immobile and panting for air, for some twenty minutes, before he slowly moved off. This photo immortalizes the scene for me, the left one, with intensity and power radiating from every part of it, especially the glint in its eye, and the right one, fighting on despite the one-sided nature of this contest, holding its ground, no matter how difficult it was getting.
