Project Description


Bongo came to the centre, along with Waty, when he was 2 years old. They were in very bad shape; skinny,malnourished and very traumatized. They were seized because the chimpanzee trainer who used to rent them for advertisements, circuses and television programs did not have the correct papers. When we went to rescue them, Bongo was in a cage the size of a microwave.


Date of Birth: November 2, 2000
Place of Birth: In captivity, Valencia
Arrival at MONA: July 2002



Due to the early separation from his mother, Bongo was very insecure. He was so traumatized that he did not trust anyone and was so insular that he spent many hours stress-rocking and sitting on one leg, which would then affect his movement. At first he didn’t dare to laugh and concealed laughter when he was tickled. Until the age of seven he lived with The Family Group, and Romie, the old lady of the group, exercised the role of foster mother, and even taught him how to eat solids (because up to that point he would only feed from bottles since his rescue).


Today we can say that Bongo has overcome all of his problems. He’s never returned to the stress-rocking or the strange sitting posture he used to exhibit and nowadays laughs loudly when he plays. When he was 7 years old he moved to The Males Group and his integration was seamless. From a young age he’s been completely black and has become a spectacular chimpanzee with great athleticism and intelligence.


He belongs to The Mutamba Group. A couple of years ago, during one night, he defeated the dominant male at that time, Marco. But he doesn’t seem to be able to take the alpha position completely, probably because he’s just a teenager and doesn’t inspire enough confidence in the other group members yet to occupy such an important position.


  • He loves to impress everyone with his strength and does not care whether the spectators are human, his enclosure companions, or his family group neighbours; he does not discriminate!
  • Bongo is one of the few chimpanzees at MONA who likes to make a sleeping nest in a different position almost every day (in the wild, chimpanzees never re-use a nest, but in captivity they usually have a preferred place for the night).


  • When visitors come to MONA, Bongo sometimes welcomes them by throwing dirt over the fence.
  • When Bongo makes a display of strength, he always starts by ‘blowing a raspberry’ (a noise), and finishes by doing some impressive jumps and thumping his chest.
  • When Bongo’s having dinner he always asks Toni for some of his rice.
  • When caregivers need a chimpanzee to help remove the straw that sometimes blocks a sliding door (from one area to another), Bongo is always the first to help and very happy to do so!


He is part of the group we call the Mutamba.*

Mutamba: Strychnos spinosa is a native tree of tropical and subtropical Africa. After the rainy season it produces a sweet, juicy yellow sour fruit, a supplemental source of food for the rural population and a highly nutritious fruit that also feeds many animals, including the monkeys. In fact, it is also named “spiny monkey-orange”.
