Creepy black smoke circle in sky is back

[ThePaladin]

I noticed with all of those birds flying around like that, that it maybe a bunch of bugs flying in an odd circle, because those birds looked like they were picking things out of the sky. Maybe the ring is just a concentration of the bugs, and the rest were more scattered.

When we lived in Germany, birds came out at dusk and swooped and flew around until dark. They weren't after bugs, they just seemed to be flying. When there was a total solar eclipse, as totality approached, the birds came out and did their flying thing just as if it were dusk. The video appears to have been taken at dusk, so the birds would be flying about.

While it's possible that it could be insects, I dunno. Whatever it was, it kept the circular shape intact as it moved across the sky.

Not a portal, though.
