On September 19 at about 07:30 I saw a flock of slightly over 600 Common Grackles in an urban park – Crescent Heights park. I had never seen such a large flock before. They were feeding on the ground, eating acorns from oak trees, and feeding on the seeds left in pine cones, in other words, they ate almost anything they could find. The colours on them were brilliant – dark blues and purples. Quite a sight. Several early strollers also stopped to watch them.
