Researchers from Northeastern University, MIT, and the University of Glasgow taught a group of domesticated parrots to make video calls to each other using tablets and smartphones. The parrots were able to initiate calls, recognize each other, and form friendships. The study suggests that video calls can improve the quality of life for pet parrots by providing social interaction and mental stimulation. The researchers caution that introducing video calls to parrots requires careful handling and monitoring to avoid stress or aggression.
