The mystery that has baffled the internet over whether a man is stroking a rabbit or a raven has been solved.

Dan Quintana, who filmed himself in the clip, has now put viewers out of their misery and disclosed that he is petting a bird.

The biological psychiatry researcher at the University of Oslo, posted the video with the playful title ‘Rabbits love getting stroked on their nose.’

But Mr Quintana has now revealed the true species and highlighted that at one stage the raven blinks with a translucent membrane – something rabbits do not have.
