We have lots of Grackles here. They are pretty smart, too. I was amazed to witness a survival skill they've developed.
When it's 100+ degrees and water gets tough to find, I've watched them milling around at red lights, dashing under the waiting cars so they can drink the condensed water dripping from the car A/C systems.
Not letting it hit the ground, but catching the drips!
They also love the sound of the lawn mower. They follow closely behind as you mow to catch the snacks (crickets, etc) you expose.
