These primates are of the species Macaca sylvanus
, the only genus of macaque that lives in Africa and the only primate, apart from Homo sapiens living in Europe (Gibraltar). Pipa belongs to the only group of macaques living permanently in MONA. The group is formed by two females and two males and is led by Pipa. In the wild, Macaques live in groups containing males and females.
Higher ranking individuals get first access to food and other resources, which means here at MONA, with Pipa being the dominant female she gets first choice of food and enrichment.
Katy and Titin are interchangeable in the middle of the group. Depending on the situation and day, Titin can rank higher than Katy and on other days, Katy can rank higher than Titin.
Katy threatens humans a lot, mainly when Pipa can see her. This is because normally when caregivers are in close proximity it means the Macaques are being fed and Pipa always wants to eat first. If Katy is seen to be threatening the caregivers there is nothing for Pipa to attack her for. Basically, she is trying to deflect any negative attention from Pipa towards humans. However, when Pipa is not around Katy is calm with her caregivers.
