SOUND ON! 📣 What species felt particularly chatty this morning? . . . The highly intelligent Japanese macaque uses a variety of vocalizations to express their emotional or physical state, respond to happenings in their environment and convey specific messages to one another. When you visit the troop at the Zoo, listen for high-pitched squeaks and squeals, coos or barking alarm calls. #DetroitZoo #GuessthatSound
