I'm having one right now!!!
I've set up at a local look out that has thick scrub behind me,across the road. I heard some piggies earlier and thought they'd just move on if I was noisy. Well I'd set up the shots, had attached dew strap and was heading back to car to turn it on when the blasted thing started going off at me!! Grunting and carrying on. I bolted into the car and shut the door Glad I started the imaging run cause I'm staying IN the car for now.
