The researchers suggest that one explanation is that the birds' perception is physically different, with the location of their eyes ensuring that only a small part of their visual field can receive input from both eyes. And that's enough to tell us that their perception is quite different from ours. But one thing is clear: in the magic situation, where most humans got things wrong, the birds consistently guessed the right hand more often than not. Overall, the results were pretty confusing, with the birds' worst performance coming in the control experiments in two of the three cases. But in this control, the birds got it wrong 86 percent of the time, indicating that any learning of this sort is pretty limited. The researchers only had six birds, so some of the corvids' good performance may have come from learning where to expect the food. But they were often confused by the control experiment, in which the worm was retained in the original hand. And for the fast pass, where the worm does change hands, the birds weren't fooled at all. The birds did the worst on the control and did somewhat better when the worm was retained in the original hand (the magic condition)-and better still when the trick was performed slowly.įor the French Drop, the conditions didn't matter the birds consistently guessed the correct hand. Humans did well both on the slow transfer, where they could see what was going on, and on the control, where the worm was actually transferred. Results for the palm transfer were confusing. Slowing the process down so people had a better chance to see what was going on allowed almost all the humans to pick the correct hand. They chose the wrong hand after the palm transfer 115 times out of 160 tests they got the French drop wrong 120 times and they missed the fast pass 140 times. Out of 160 tests for each trick, humans were typically misled by the magic. The researchers got good enough at the tricks that they could consistently fool humans. Rather than relying on misdirection, this trick required that the actions take place too quickly for anyone (or any bird) to follow where the worm ended up. AdvertisementĪnother trick involved hand motions that obscured what was happening-and then an actual transfer of a worm to the opposite hand. The palm-to-palm transfer operates similarly-the object appears to be transferred but isn't. One was the French drop, in which the audience is convinced that the performer has moved an object to a new hand when it's actually retained in the original hand. Overall, the researchers tried three different tricks. So the researchers instead performed magic tricks with worms, which the birds were definitely interested in. So it's not a stretch to think that magic might be something birds could comprehend.īut unlike humans, birds aren't likely to be interested in what happens to coins or cards.

Many species of jays cache food (if you've ever found that oak trees have been seeded in your flower pots, jays are probably why) and often engage in elaborate deceptions to keep their fellow jays from stealing their caches. The birds in the study were Eurasian jays, who are part of a family (corvids) known to be unusually intelligent.

But a new study attempts magic with birds and finds that many tricks just don't work with them. Unsurprisingly, most early experiments were done with other primates, as they would likely have a lot of overlap with us. If the trick fails, we can identify points where our understandings of the world diverge. If animals are also fooled by magic tricks, we can identify where our cognitive skills overlap. Understanding why magic works can tell us important things about how humans direct their attention and form expectations.Īt some point, behavioral scientists realized they could take this idea and apply it to animals. To fall for a trick, people have to see things they perceive as important and ignore things that are actually important. Most magic tricks require a fairly sophisticated understanding of how humans perceive the world.
