I was eating dinner one evening and saw this happening again outside. I’ve encountered this a couple of times in the past and I see it very rarely. I don’t know why a bunch of sparrows would start swarming one area, but it is pretty cool to see. I couldn’t cut out some parts of the video so feel free to edit it if you want (sorry if that’s an inconvenience) Also, I don’t really want any money, just answers lol. Love your uploads!
