Grackles cackling for Halloween

I've just had a lovely weekend in Austin, Texas, and I'll have details at ten, as they say on the local t.v. news teases. I do need to broadcast this late-breaking Special Alert:



(Not an actual photo, sorry! This is an artist's conception, to use N.A.S.A. lingo.)

We stayed at a very pleasant hotel at the junction of I-35 and Highway 290. The yellow warning sign shown above was posted under the trees in the hotel parking lot. There was no oppressive build-up of grackle splats on the parking lot surface. Maybe it is just a warning sign of our litigious society. Heaven help us if a driver parks under a tree and the car is decorated by mulberry-eating grackles and cowbirds!
