This might be one of the coolest bird things I've ever seen.
Oh wow, talk about perfect timing with that last photo!! I've heard of starling murmurations, but have never actually witnessed one myself.

To my knowledge we don’t have murmurations. I have never seen such large groups of starlings here in Michigan, although they are very abundant here. Some people consider them a threat to the native wildlife (especially to the bluebird population). They have been known to invade bluebird nesting boxes and lay their own eggs in them. I don’t particularly like starlings for understandable reasons, but the large gathering of them could be a spectacle.
Here is some more information about starlings in Michigan:
