These were new for 2009. They were so simple - a framework of 2x2s, some Goodwill clothes (aged up a bit), and some raffia zip-tied to hang out of each wrist. The heads are the talking Rotten Skulls from Spirit a few years back - they never worked right, but they look good, and it felt good to get to use them for something for once. The crow's eyes light up and he caws; the bloody eyeball was made and added by us (just wire with hot glue over it, then painted).
My hint is to buy women's clothes (or at least men's size small) for scarecrows, since it seems to fit the proportions better.
