While walking in Jackson Park last Sunday (Oct. 4) in the late morning, I saw the most amazing swarming of Common Grackles. There were thousands of them. What a spectacle! It was like the Hitchcock movie, The Birds. Everyone was in awe and the noise was deafening. I’ve seen large swarms of starlings before but nothing of this magnitude.
