In 2000, Rafael Reyna-Hurtado spotted a herd of white-lipped peccaries for the first time in the Mayan Forest. The sight, he says, took his breath away. Never before in his life had he seen nearly a hundred animals of the same species move so steadfastly, perfectly in a straight line, he says.
“I was amazed,” Reyna-Hurtado says of unexpectedly encountering them while helping a friend study tropical deer in Mexico. “It’s a reason why I wanted to study peccaries.”
