From the ol' JSH mailbag:
Hello there! I was googling "weird bird vortex" and your blogspot popped up and while I didn't investigate all the archives, I did think maybe you would have heard something about it.
About twelve years ago I lived in Bowling Green, KY and I was walking toward the square and I espied what appeared to be hundreds of starlings swirling in a cyclone pattern over the parking lot of the community services building. I asked a friend about it and he said that it happens every year on a certain date and is something akin to the egg-standing-on-end phenomena.
Have you ever heard of this and if so could you give me your knowledge on the subject? Much appreciated.
Unfortunately, I haven't heard anything about the connection of starlings to the balanced egg phenomena, although it sounds fascinating! Any other readers know anything about this?
I do remember taking some pictures in Georgetown, KY last year of a huge murmuration of starlings, who were swirling for over an hour in a peculiar sort of frenzied cyclonic cloud, much in the same way as in this video but more consistently figure-8-shaped. Going back through the files now to retrieve them.
