Jeff, i have never tried it over a carcuss. im clueless on that one. I put a cam over a carcuss last year and got nothing but buzzard pics [&:](in the woods)several years ago i laid one behind my house in a picked field and had a yote feeding on it in the daylight hours. I think Yotes tend to be seen more when its super cold out cause they got to keep that fat content up to survive. IMO!!
