Serengeti National Park encompasses 5,700 square miles of grassy plains and woodlands near the northern border of Tanzania, and is home to more than 3,500 lions grouped into a couple dozen prides. Photographer Nick Nichols and videographer Nathan Williamson made several extended trips to the Serengeti between July 2011 and January 2013, determined to break new visual ground in their coverage of the Serengeti Lion. The pair used cameras mounted on small remote-control vehicles to make images up close and at low angles, as well as hand-held cameras for both day and nighttime shots. Nichols shot 242,000 images and Williamson recorded 200 hours of video, often while lying on the floor of a specially outfitted Land Rover. Hildur, C-Boy's partner, frequently makes a long run to visit the Simba East pride. A coalition that controls two prides must maintain vigilance over both.
