There is no lack of great sounding sparrow ID courses. Here's a snippet from one:
"To flush the birds from their hiding places, he (Tim Keyes) and his fellow co-leader, ornithologist Gene Keferl, brought along a 60-foot rope with weights attached in the middle. During our field sessions, they dragged the rope length-wise through the dense marsh grass of a salt marsh and through the tall weeds of an old field to get the sparrows to come out."
I just think that's hilarious.
