I baited a Hav-A-Heart trap with a quail corpse set on the opposite side of the hole I figured the weasel was using. I don't know if it was the dead quail or that the Hav-A-Heart was seen as a thoroughfare, but I caught one that way.

My first experience with one was a coop full of dead pigeons. The first few that I quickly inspected had no obvious "trauma," so I concluded that their food had mold or something that killed them all. It wasn't until I saw a pigeon with no head did I go back and look closer at the first birds and discovered they had a vampire like injury to their jugular.
