History: It is unknown where Abu was born, but it must have been around 2004. He arrived at MONA in 2008. He was bought illegally and kept in a private house, spending the first 4 years of his life being locked in a very small cage without stimuli or company of other macaques.
Personality: He seems to be very open and wants to be integrated into the macaque group and generally acts very cooperative towards the staff if veterinary treatment is needed. He has limited social skills, especially when it comes to prove himself within the hierarchy which is an important ability to be fully integrated and accepted within the group.
