I'll admit it, I play golf. Our local public course is inundated with these guys. Makes putting through goose poop very frustrating! But I've witnessed this type of maneuver on a couple of occasions. I think they may be on some sort of psychedelic from the fertilizer!
We have Canada geese here on my little lake -- every now then I hear them and then see them coming in for a landing or taking off -- now I'm going to start watching to see if anybody's upside down during the process! LOL!
