I recently wire-tied a dead mallard (breast meat removed) to a tree and set up the trail cam to see what wanted it. I must have wire-tied it well because it took them two or three nights, but a raccoon and a possum finally finished it off. This video is roughly 72 hours condensed into 2 minutes. BTW, there was one single video clip (goes by too fast to see) when a coyote passed by the mallard, but he apparently never slowed down to check it out. Bon appetit!
