The nature of this amazing photo taken by Nuray Gonulalan is up for debate down at ScienceBlogs. Is this some a masterly creation with the aid of photoshop resembling a flock of starlings forming a tornado-like column or something more sinister akin to Hitchcock's "The Birds"?

There are many clips on youtube of starlings flowing in and out of beautiful formations like schools of fish.

It's only a couple of minutes worth. But I stood there for an hour in amazement.
