2. Population management & Animal welfare

Funders

Ongoing activities

□ Maintained frequency and diversity of enrichments in each section

□ Special Easter event: Distributed eggs to all the primates to celebrate Easter and give extra proteins to the animals.

Specific activities

□ Chimpanzee: Completed the integration of Papa and Nanga (two adult males) in the Mainland group (Image 1)

□ Chimpanzee: Completed the re-integration of Koto (adult male) into the Island

Group after 8 months of intensive daily cares, treatments, and enrichments to treat multi-abscess (Images 2-3)

□ Mona Monkey: Transferred Edogue (adult female) from Saker’s group to Mantum’s group and started introduction with her new group (Image 4)

□ Olive Baboon: Completed the re-integration of Mboppi (adult female) into her group after 8 months of intensive daily cares, treatments, and enrichments to treat multi-abscess (Image 5)

□ Red-capped Mangabey: water pressure machine cleaning of Eta’s enclosure and re-enriched the enclosure with new branches (Image 6)

□ Vet cares (April 2021): o Boosting primate immune system during Covid-19: providing on daily basis vitamins, plants infusion, extra protein and other nutritional enrichment to all primates (Image 7) o Primates: 131 individuals treated; 4 anaesthesia performed; 11 individuals sampled (1 blood samples for haematology analysis, 1 blood samples for biochemistry analysis, 10 faecal samples for coprology analysis, 0 pus swab for microbiology analysis); 0 contraception; 0 identification with a microchip; 0 laceration repairs; 100 drug therapies: 61% dietary supplements, 12% expectorant, 11% antibiotics, 6% topical disinfectant, 5% anti-inflammatories, 5% others; 0 death (Image 8) o African grey parrots: 11 individuals received extra care and nutritional supplement to boost feather regrowth; 0 deaths

Image 1. Nanga (newly integrated); Pecus (dominant male); Papa (newly integrated) Integrating chimps into a new group is a complex process that requires thorough observation to understand the progress and detect a possible issue. In the first picture, dominant male Pecus ( )approaches Nanga, newly integrated ( ) to show his dominance over him. Nanga is stressed, and Papa, the second newly integrated ( ), to

support Nanga, makes a gentle attempt to divert Pecus’s attention. But Pecus remains focused on Nanga and therefore Papa prefers to walk away to avoid the conflict. As a result, Nanga will have to face Pecus, submit to him and accept his dominance. The hierarchy is strengthened, which enables the group to stabilise. This process will repeat itself until each individual finds their place in the hierarchy.

Image 2. Dominant male TKC (right) and Koto (left) are having positive social interaction after 8 months of separation. Quickly, TKC accepted Koto back to the group.

Image 4. Edogue, a female adult Mona monkey (on the right), was transferred to Mantum’s group and placed in a satellite cage in a separate room to be progressively introduced. All individuals came rapidly to meet her and establish relationships Image 3. Koto enjoyed getting back out in the enclosure: he walked, foraged and interacted with the other individuals!

Image 5. Separated for several months for multi-abscess treatment, Mboppi is now back roaming in the baboon enclosure and enjoy walking, foraging and all social interactions with all the members of the group.

Image 6. The Red-capped mangabeys enclosure is enriched every week with fresh branches, elephant stalk and some peanuts scattered everywhere on the ground. Image 7. As the second wave of Covid-19 arrived in Cameroon, plant infusions are given to the great apes every other day to boost their immune system. We provide a wide variety of plants like ginger, hibiscus, turmeric and garlic.

Image 8a&b. An intervention was necessary on Nde, an adult male drill, because of a bacterial infection that spread and created a large opening on the left tight. Every day, the vet team changed his bandage, checked the condition of the wound and cleaned it for a quick recovery.

May 2021 objectives:

□ Continue with the ongoing activities

□ Drills: Complete the integration of juvenile male Mbigou into the group

□ Mandrills: Start the re-integration of adult male Nimbus to the group

□ Mona monkeys: Complete the integration of adult female Edogue into Mantum’s group.
