On a late-afternoon game drive in the Naboisho Conservancy, in Kenya’s Maasai Mara, I had a wildlife encounter that Sir David Attenborough could have been narrating.

Not five yards from my vehicle, a pair of lions began to mate, a ritual that took about 10 seconds. Afterward, the female looked bored, and then, perking up at the grunts of nearby warthogs, hungry. She wanted dinner and rose to procure it. (Lionesses are the hunters in the pride.)
