Each morning when I'm down by the river at sunrise this time of year, clouds of blackbirds or grackles make their way across the river as the sun comes up. This morning I skipped the morning walk and sit down by the river and the flock came to me.
It was pretty mind altering to be sitting quietly in silence and hear this cacophony right out the back door.
