The Birds

We often see large swarms, flocks, whatever, of Starlings and other birds move through during migration season.  I've seen swarms of Grackles while in Texas, but I think this was the first time I've seen Grackles in such groups here in Alabama (I may have seen them and just thought they were Starlings).  The photo doesn't do this crowd justice.  I could only capture about 20% (if that) of them at any one time.
