@TheBookEscape, Pretty sure it is a flock of many many bords. The bord are be wings. No stingers is not but. Many bord out of truck at time and bord core not.
So, after watching like 30 times, I think I figured it out. The truck is hauling birds. And all the cages are opened at once. I'm assuming her, but the guy running away probably did it.
Pigeon racing is actually extremely popular among wealthy Chinese men. This GIF is the beginning of a pigeon race where they are all released at once and must fly to a predetermined location
I have no idea what's going on here...
