Paris - Ravens can imagine being spied upon by a hidden competitor, showing a capacity for abstraction once thought to be exclusively human, according to a study released on Tuesday.
In a clever set of experiments, scientists showed that the famously intelligent birds take extra care to hide food if they suspect their movements are being monitored by another raven, even when the second bird is not really there.
