I have the "fish tree" set up, as I mentioned in Backyard Camera Trapping last week.
Nothing TOO exciting has showed up yet, except maybe a coyote???
Notice the plastic container in the picture below. When I was checking the camera at one point, I deployed a weasel attractent scent (I'm dying to get that fisher back...), and hung it on a branch while I was checking the SD card, and apparently forgot it.
On my way back up to check it a few days later, I found the container at the edge of the woods, and thought, Well, THAT'S weird..., but when I checked the camera, I had my answer. Damn crows!
