Lion Yawn, KenyaA lion’s yawn might look sleepy, but it’s often a social signal rather than just a sign of tiredness. Lions yawn to help wake up the body and brain, especially before a burst of activity like a hunt or going on patrol. Among pride members, frequent yawning can also help synchronize group behavior, like getting everyone up and moving around the same time.
