10 Fascinating Ways Animals Communicate Everyday

3. Gorillas Hum to Call Members

When it’s time to eat, gorillas have a charming way of making it known—especially the alpha of the group. They’ll often break into soft hums or low melodic sounds, almost like a gentle song, to signal to the group that mealtime has begun. It’s not just noise for the sake of it; this behavior serves a practical purpose, letting everyone know that food is available and encouraging the group to gather. But there’s more to these hums than just communication. The sounds also seem to express contentment, similar to how a person might let out a happy sigh during a delicious meal. Experts believe this vocal behavior strengthens social bonds within the group, creating a sense of harmony as they share food.
