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"?

It's only a couple of minutes worth. But I stood there for an hour in amazement.
There are many clips on youtube of starlings flowing in and out of beautiful formations like schools of fish.
