Mr Olsen said: 'My footage felt very special as nobody ever manages to see how the herd moves as one body from the air. It's watching a huge flock of birds in flight.

'Filming the event was a spur of the moment thing as the reindeer stay well away from urban areas and it's a trek out to find them.

'Using a drone was always just a hobby to me, but I get a lot of satisfaction out of the footage as it is so rare for somebody to film from the sky above.'
