Updates from camp:

  • As part of our new quarantine procedures at the Ozouga camp, a wooden cabin has been constructed as a transit between the forest and the camp. All clothes and shoes used in the forest are confined to this hut as a means to reduce contamination risks between humans and chimpanzees.
  • We have a new PhD candidate, Lara Southern, joining us this year to study the communicative interactions of the Rekambo males with a special focus on how this unique environment may have shaped communicative complexity and individual profiles.
