Many studies have shown that certain primates and birds behave differently in the presence of snoopers, i.e. the peers who might want to steal their food. While some researchers think this shows a theory of mind, others say they might just be reacting to visual cues, rather than having a mental representation of what others can see and know.
However, a new experiment shows that ravens hide their food more quickly if they think they are being watched, even when no other bird is in sight.
It’s the strongest evidence yet that ravens have a "theory of mind" – that they can attribute mental states such as knowledge to others.
