• Special measures at the beginning of association: Species were repeatedly associated
for a few hours and separated at night.
• Special behavioural observations (intra- or interspecific): Species did not mix up
their groups and stayed spatially separated. In March 1999 the breeding C. penicillata
male was replaced by a new male. This new male showed severe aggressive behaviour towards
the owl monkeys and caused the termination of this association.
• Problems and risks (animals, technical, vet. medical): Problems arose with the introduction
of a new C. penicillata male which harassed the owl monkeys until they fled to the
ground.
• Cause of problems and trouble shooting: After several unsuccessful attempts to reassociate
the groups, association was terminated.
