Leopards are fiercely territorial and if you spend enough time in one place, you get to know them personally.
This leopard was one of my all-time favourites. His name was Tyson, due to his propensity to not shy away from a brawl. Here he sits aloft a termite mound, softly lit from the side by a spotlight. Note the nick on the bridge of his nose (Sabi Sand, South Africa).
