Have you ever paused to think about how magic works?

In order to trick the brain, magicians need to understand the brain - its processes of logic and capacity to predict the future.

So being deceived by tricks actually requires a level of intelligence.

Nicola Clayton and her team at the University of Cambridge decided to create a series of sleights of hand designed by in-house magicians and psychologists to test the cognitive abilities of a species of crow.

The crows themselves employ a type of deception to fool scavengers about where they hide their food.

Watch the video to see how they react to human magic.
