On November 10, 2015, large numbers of white-lipped peccaries moved across the town of Caracaraí in Roraima State, Brazil. Many became trapped in yards or were killed by townspeople. Caracaraí has a population of over 10,000 people. Jose Fragoso (1997, 2004) described these exceptional movements as possible population level dispersal events or perhaps a herd that abandoned its usual home area after long term persecution by humans.
