I was on another message board looking at some paranormal topics whilst my wife was watching a show that I had no interest in. On the board I came across these videos claiming to show pixies in their natural habitat.
Filmed by a chap named Erwin Saunders, they may be a product of rather good CGI or not. That, I'll leave up to you. His reaction to seeing/filming them seems genuine and surprising, but then he may just be a good actor.
Nonetheless, whatever you make of it, the footage is rather endearing.
Video 1 - Pixie makes appearance at 6.15
Video 2 - Sightings occur at 9.39 and 10.34 when it steals his lunch (a sandwich)
