Since starlings are ground feeders, that can't be it. Doesn't look like courting behavior either, as it would serve no purpose in that regard. It could be for flock protection because predators couldn't get as many. I think it is bonding behavior, so keep the flock connected as this is definitely a flocking species. Maybe someone knows the actual purpose, I am just using an educated guess.
Thank you. It is interesting to watch though I have to say that.
