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.
More than 170 white-lipped peccaries were filmed crossing the Rio Branco River in Caracaraí County, Roraima, Brazil in the Amazon. The peccaries were filmed for over 30 minutes when in the middle of the almost 2 km wide Rio Branco by agents of Brazil’s wildlife agency Ibama. Recording made on November 7, 2015.
