The Parrot With a Call as Infectious as Laughter 🔗 🦜

By studying these birds, Schwing also realized that they have a ‘play call’—a warbling noise that they make while they’re playing. And the call isn’t just a statement. It’s also a trigger. It seems to induce playfulness in other keas within earshot; when they hear it, they also start playing with nearby peers. It has an infectious quality—just like human laughter. ‘When kids play and laugh, other kids want to play more,’ says Schwing. ‘And this still exists in adults: That’s why American sitcoms have laugh tracks.’
