In a lecture on the "Meaning Crisis", John Vervaeke, an assistant professor of cognitive science at the University of Toronto, and a colleague of Jordan B. Peterson, states:
Caledonian crows will tumble down roofs in order to make themselves dizzy for no other purpose than to alter their state of consciousness.
I believe vertigo does affect animals other than humans, including birds, which makes me wonder why any animal would intentionally induce such an awful feeling, and why crows specifically, as opposed to any other animal that could easily do this (think dog chasing their tail for example) if they actually enjoyed the experience.
Google did not yield any matches resembling this claim. Is this claim supported by evidence?
