It would be nice to have an unedited version of the video. One take uninterrupted, instead of being cut, zoomed around and cropped. But, just from the lighting, it looks to me like all the frames in this video are at about the same time frame. The sun has not moved much.
Silk threads, or some thread-like object, sounds like a perfectly good explanation. I would be surprised if this is not the answer. They do look mostly vertical, but their angle varies slightly, they could be connected on both top and bottom and almost taut, just sagging slightly, so they wobble around a bit. They would be illuminated by something like a pillar of light passing through a slot, similar to the space between boards in the door to the back, but on a different angle. I'm thinking it's one of those ceiling holes.
As they move around they "sample" the shape of the beam of light (I'm having a hard time putting this in clearer words), and I think the shape of the light beam could be inferred from this "sampling", which would give us a rough shape of the hole where the light is passing through.
Also, even though the threads appear to be one next to the other, in the same "plane", at the same distance from the camera, that's an illusion. The one that appears higher up is farther to the back, so it crosses the pillar of light at a higher point. Taking this into consideration, when they appear to move up and down it is actually back (away from the camera) and forth (closer).

Looks to me like dust and small debris that was disturbed by the bird's flapping. Might as well be insects, but I don't see a way to make that distinction.A flurry of insects appears at around 0:24 right after the bird flies off at 0:22.
We have a fairly good idea of the position of the sun based on the illuminated ground, and it is in front of the camera. That's why the threads would have to be backlit.Does it have to be backlit for highlights to appear?
