I think I see what you are seeing. Basically there is a mat of pine limbs on the ground that would have been above the the snow that is not present in the rest of the woods. Is that why you think it is a BF nest?
The reality is it is impossible to prove or dis-prove that this is a real BF nests. Odds are frankly against it primarily due to the fact that BF, if they exist, are exceeding rare, their nest are even rarer and weird tree formation caused by nature are a dime a dozen and it is very very hard to determine the difference. That does not mean you have not found one, just that the odds are stacked against you. Your video was a pain to watch and I recommend if you see these again to simply take hi-def pictures to tell the story with annotations. My primary concern with your area is the deadfall and bent limbs look to me to be most likely caused by the weight of snow over the winter that recently melted away. I would be more convinced if you were able to show prints (Foot, hand, and/or body) in the area, limbs deliberately woven together to hold in place, limbs deliberately stacked in a manner that would be close to impossible via natural causes, and better cover over the nest.
I have run across 2-3 potential nest over the last 2 decades and never was able to get a photo or video that did them justice. Here is one from last fall which I am sure will not look like a nest to anybody here. But what is not captured well is that it is a tight leanto that was built off of a recently fallen tree, many of the branches had to be deliberately stacked by something with hands, and there is a perfect pocket inside of it with a leafy floor. Also, I found the nest following a path of bent trees with the last one being quite impressive and looks to be created by someone/thing of immense size and strength. This story is probably worth its own thread if I ever get motivated enough to put it together.
My 2 cents and happy hunting. Remember, it is getting out in the woods and experiencing nature that is the real fun.
