Randall would say: “Oh those birds are just crazy! Look at them swarm and oh, look they’re turning again and diving! Get out of my way stupid, I want to go this way now!”
When growing up I would see maybe a quarter of that amount of red-winged black birds doing the same thing however they were constantly chirping, and over the large fields you could hear thier wings cutting through the air as well.
I saw something quite similar in Italy as starlings (presumably) migrated to Africa. My mom thought someone had pelted our villa with grapes after they flew over but we quickly realized they had been eating in the vineyards and as the massive wave flew overhead they dropped little purple bombs of poo. It was an amazing sight and it elicited giggles from grown men not unlike the girls in the video. Something you never forget. Glad I took the time to watch.
