I have a decorative scarecrow that I put up this time of year. For Halloween he carries an extra large meat clever and for Thanksgiving he just hangs out. Since he hangs out right next to the birdfeeder I can't say he scares the birds much. But to his credit, I've not seen any crows there.
The Fine Print: Not just any chili peppers I should warn you, but Hatch, NM, chili peppers. That's like the gold standard of chili. All stamps by Copper Leaf Creations.
