Kea Birds' Playfulness and Behavior

Biologist Raul Schwing studies the playful behavior of keas, a bird species known for their extended playfulness into adulthood. His experiments reveal that keas are attracted to vibrant colors and new objects, which stimulate play. Schwing discovers that keas use a specific play call to encourage group play, similar to how infectious laughter works in humans. This play call can instantly change the mood of keas, making them more playful. The study is the first to document such an effect in birds, highlighting the social and communicative complexity of keas.
