Clearly thats a flying Stingray…..
I would have to guess an owl or bat. Every once in a while I will get a random figure like that on my cuddebacks. Its always a bird of some sort. It will either show up clear on the next pic or on the video. I get a fair amount of birds cause ill often throw out a gallon or two worth of cracked corn when I replenish mineral. Gets the deer in front of the camera for a bit longer as they mill around and check every thing out, giving me a ton of different angles to check out their head gear.
If its a UFO ask them if they have deer there, Im looking for another property to hunt
