Selected Mixed Species Exhibits of Primates in German ... - DPZ

• Special measures at the beginning of association: L. catta group was habituated first
to the enclosure. Then E. f. albifrons individuals were successively associated.
• Special behavioural observations (intra- or interspecific): With increasing group
size of E. f. albifrons aggressive interspecific encounters occurred, including some biting especially
during feeding.
• Problems and risks (animals, technical, vet. medical): see above
• Cause of problems and trouble shooting: Spatially dispersed feeding solved problems
of interspecific aggression.

• Special measures at the beginning of association: C. guereza was habituated first to
the outdoor enclosure. Then they were kept indoor for two days, when E. f. albifrons was habituated
to the outdoor enclosure. During this habituation phase E. f. albifrons was already
visible for C. guereza. Then species were associated in the outdoor enclosure.
• Special behavioural observations (intra- or interspecific): During a short period of
time (1-2 days) C. colobus gang together and browbeated individual E. f. albifrons, but did
not bite them.Thereby a species hierarchy was quickly established.
• Problems and risks (animals, technical, vet. medical): none
• Cause of problems and trouble shooting: Dispersed feeding, 4-5 times a day twigs with
fresh leaves for C. guereza.

• Special measures at the beginning of association: The group of Barbary sheeps was
introduced to the outdoor enclosure when Barbary macaques were already present.
• Special behavioural observations (intra- or interspecific): Sociopositiv (playful) behaviour
between juveniles of both species were observed. This includes riding and jumping
of monkeys on sheeps.
