Gregory's Server@AdditionalQuench @MeanwhileinCanada It's actually the imprint of takeoff. The owl's wings were up went it hit the snow, then downward for takeoff.
This vid shows a nice view of the position of the wings (there are some good videos to watch these days of owls hunting); https://youtu.be/w4OH6gMN6vY
@julescelt01 @MeanwhileinCanada I watched this on tv once, cool show, in fact the memory of those slowmo videos of their kill move was part of my initial skepticism. And slapping the ground on takeoff to make a perfect wing imprint sounds inefficient & unlikely. But it's the internet, so believe whatever possibility you brings you the most joy I suppose.
