? Did you know: Orangutans use facial expressions and body language to communicate. Among the vocalizations they use are kiss-squeak and belching vocalizations when they are upset, and a loud, deep long call used typically by males for long-distance communication.

Meet our primate keepers and learn more about our orangutans at the 1:30 p.m. Think Tank research demonstration! PLAN YOUR VISIT: https://nationalzoo.si.edu/visit/daily-events.
