That's quite an interesting piece of video.
At .14 what I'm seeing (in HD on a large screen) is movement of what looks like a huge "U" shaped set of antlers or branches with a central "figure"
Over the next 3-4 secs the figure moves to our right (together with the antler/branches) and then stops.
The figure then drops down low to the ground (from our perspective) and stays low for a few secs.
It re-appears (as if standing up from a crouched position) in the same location but at an angle, leaning towards our right.
It pauses for a few secs, then moves off to our right and gets lost from view as the camera pans left.
I don't really see any antler/branches after the pause and drop-down, so I'm thinking that the start of the video maybe
shows someone (or
something!) standing still, holding a large "V" shaped branch. They then lift & carry that branch off to our right for a few steps before setting it
down. Maybe it falls over and that's when the drop-down takes place?
They drop down out of sight, perhaps unsuccessfully trying to retrieve the situation, and then re-appear bent over at an angle (tired or maybe looking
down at the branch thing?).
They then decide to leave it and wander off to the right again...
I don't see any birds/bats or similar.
I've taken some screenshots and cropped them (with notes) to make it easier to explain what I'm seeing:
I've also joined these into an animated gif which makes the movement a bit clearer:
***If you watch the video again (in HD) after seeing this animated gif, it's easier to see what's going on then.***
I think that it could
be a large Elk of similar, but I don't see the main part of it's body as it moves to the side?
I think it more likely to be a bipedal (human or...?) holding a large "V" shaped branch, which it then drops...
What do you guys think?
