Nowadays, anything curious that circulates on the Internet can go viral.
But this time, the latest trend is an optical illusion that emerged from a video on Twitter posted on Sunday.
Daniel Quintana, Principal Investigator in Biological Psychiatry at the University of Oslo in Norway, posted a short clip on his page that shows an animal being rubbed on the head that many wonder if it is a bird or a rabbit.
"Rabbits love to have their noses nuzzled," he tweeted. "I thought it was pretty clear that the video was of a bird," he concluded, planting a small seed that revolutionized tweeters. Quintana reportedly used a video released by Imgur photography service on Saturday.
"As you can see, the translucent nictitating membrane stretches horizontally across the eye (rabbits don't have membranes like this) and the position of the" ears "is a little bit strange," he said. "I made the rabbit comment to the main readers so they would think it was actually a rabbit, to give it at least one chance to fight. When you only see the beak in your peripheral vision, it really looks like it's ears. Without this misleading signal, I thought most people would have seen a bird, "he told CNET.
The idea was based on "the static bird / rabbit illusion" created by psychologist Joseph Jastrow in 1899 as a way to demonstrate the power of suggestion.
"The static bird / rabbit illusion is well known in psychology and philosophy, so when I saw the [Imgur] video, I thought it would be interesting to share it," Quintana said.
As expected, comments from thousands of Netizens started on what kind of creature it really was.
"That's not a rabbit, in fact, it's a Corvid," wrote one netizen. “Observe the nictitating membrane when it blinks. Instead of moving up and down, it runs horizontally through the eye like a windshield wiper and is translucent.”
Quintana finally revealed that the creature was, in fact, a bird, most likely a "white-necked crow" or Corvid. Several users were able to find the correct answer on their own.
