According to a recent study published in the Journal of Animal Ecology, birds are capable of learning good eating habits from watching others, even without being present to experience the smells and sounds. The study was conducted by Dr. Liisa Hamalainen, from the University of Cambridge, on 2 types of birds, blue tits and great tits. She made 2 types of food items out of almond flakes, some of them soaked in a bitter solution, and placed a cross or a square on an outer wrapping. The birds' reactions were then filmed and shown to members of both their own and other species. Upon eating the bitter flakes, the birds reacted with a comical disgust, making a great show of their distaste, whose meaning their viewers recognized. Both blue tits and great tits got the message and steered well clear of the bitter flakes, confirming that the educational video worked.
