Rhino notching in Lewa. (Courtesy)
How many men does it take to corner and subdue a rhino? Close to 40 perhaps, especially the ill-tempered black rhino. But it can also take one man if that happens to be Dr Michael Njoroge, the Kenya Wildlife Service veterinary doctor.
With a single shot of a tranquilliser dart each, Njoroge was able to calm 40 rhinos during the 10-day long ear-notching exercise in the sprawling Lewa and Borana conservancies.
