A video posted on Twitter on Sunday has some people thinking they see a bunny and others thinking they see a bird.

The optical illusion video, posted by University of Oslo researcher Daniel S. Quintana, shows someone petting an animal. Some see a bird, whose beak is pointing up, and others see a bunny with white on the tips of its ears.

"Rabbits love getting stroked on their nose," Quintana tweeted with the video.

CNN reported that those who think they see a bird are correct. The original video appears to have been uploaded to Instagram in May 2017 by Paige Davis, a curator of bird training at World Bird Sanctuary in Valley Park, Missouri.

Quintana said he shared the video based on the old rabbit/duck illusion.

"The static bird/rabbit illusion is well-known within psychology and philosophy, so when I saw a video, I thought it would be interesting to share it, " Quintana told CNet in an email.

"I thought it was fairly clear that the video was of a bird... as you can see the translucent nictitating membrane sweep across the eye horizontally (rabbits don't have membranes like this) and the positioning of the 'ears' are a little strange," he said.

Davis became aware of the viral tweet, and said that the bird is a raven named Mischief.

"Mischief is quite the talk on Twitter today! (Video in my story)," she posted Wednesday. "I can assure you that he is in fact a raven. And a talented raven at that!"
