Drill – Zoo Atlanta https://zooatlanta.org/animal/drill/
Drills are very distinctive primates that are related to baboons. They live in complex social groups led by a single dominant male. Social interactions are mostly focused around grooming, and communication comes in the form of visual displays and vocalizations. Deforestation and unsustainable harvest for the commercialized bushmeat trade are creating an uncertain future for this species.
