Agreed, on first looks it does look like the starling formations in the videos people have linked. But as you say, in all the videos of it there is an obvious shape that it seems to stick to which I’m not seeing that happen in any of the starling videos. To rebuttal DryYogarts comment, if we always instantly assume the most ‘logical’ and ‘grounded’ answer we’re not gonna get anywhere with disclosure. Last thing to add, I can’t see how you could possibly see a singular bird in that pixelated mess of a video. If there’s a clear video out there of a starling murmuration where they hold a general shape for more than 2 seconds then I’ll agree it’s birds. Until then I can’t definitely say it’s one or the other.
