Hiding Behaviour of Long-tailed Macaques (Macaca fascicularis): II. Use of Hiding Places during Aggressive Interactions

In an observational study on captive long-tailed macaques ( Macaca fascicularis ), the ability to hide was investigated in the social context of aggression. The use of five different types of hiding place during highly aggressive interactions was recorded and the choices of six different rank-sex classes were compared using an index of attractiveness of the different types of hiding place during highly aggressive interactions. There was no significant difference between the rank-sex classes in selection of the hiding places that could be connected with visibility: no specific location or type was preferred, either by the group as a whole or by any specific rank-sex class. Thus long-tailed macaques do not seem to hide shortly after aggressive interactions.
