Yes they do atleast dead ones. I was just standing on my back deck smokin and heard a deer coming in the woods... I have a pile of fox bodys and coons right in the backyard well a coyote came trotting right in and started pulling on the flesh, It came out into the light from my deck it was awsome. grabbed the scanner and went to check tracks and there were quite a few 20 y behind the house. Must have spoked them walking down because they started howling and running cracking stick haha. This pile also happends to be 10ft to the right of my xbow target bag. seems convinent.
