Bird or Bunny Optical Illusion. Which One Do You See?

A biological psychiatry researcher posted a short clip on Twitter showing an animal being rubbed on the head. Which One Do You See? Another day, another bizarre optical illusion doing the rounds on social media. Yup, we've already had the weird black and white/colour group shot and the car door/beach scene and now the latest is a video of a cute bunny being petted... or, is it a bird? Sharing the clip on Twitter Dan Quintana, a biological psychiatry researcher at the University of Oslo, wrote: "Rabbits love getting stroked on their nose." However, users were quick to respond to say that they saw a black bird, most likely a crow or raven, while others insisted that they saw a cute bunny getting its nose tickled. The animal can be seen as a bird which is having the back of its head rubbed, while it has its beak open; or the 'beak' can be seen as a couple of white-tipped bunny ears, while the 'nose' is being stroked.
