I was in downtown San Antonio a few weeks ago. Hundreds of birds were flying where ever I went. I thought they were pretty. They were loud though and I could see businesses and hotels having concerns.
Did you not see the mess that Grackles make?
This time of year we have all the birds down here that migrated from up north. Soon they'll start migrating back and then we get different species coming through at different times, but winter is always the busy season for bird activity.
