I suspect that the people awaiting the bats at the Congress Avenue Bridge paid no attention to the grackles because they are very used to them. They are there always and their raucous conversations are in the air most of the day, especially in the spring. We moved from Austin to West Virginia 3 years ago, and to my amazement I find myself missing, from time to time, that startling, nearly metallic sound of great tailed grackles.
