I have every predator there is except big cats and big snakes. I also live in a wildlife corridor, so there is a constant parade of hungry animals wandering through my yard. Historically, I have lost very few birds and all the losses have been due to aerial predation. I knew when I started poultry keeping that predation was going to be my biggest issue, so I planned accordingly and set up veritable fortresses for the birds to live in.
The ground near the kill site is very wet, but I found no prints at all. A big animal like a coyote or bear should have left some prints behind. The losses have all occurred during the day when there are people and dogs all around. The snatches have left little to no evidence behind. One minute everything is fine and the next minute I am down one more bird. The predator is very bold. My duck pen is butted up to the side of my house. Anything that got in there was practically in my house. The predator has to be tough. That fence doesn't move easily especially since I have it staked down with many extra rods to prevent sagging. About 20 feet of the fencing was ripped out. And it's electric. That had to hurt.
I have been assuming that the culprit is a fisher because one was spotted hanging around. I hadn't had any fisher problems for about 8 years. In fact, I haven't seen or heard one at all in several years. This one is new to the area and has decided to stay.
I am setting up my game cam to see what I can see. My Conibear was shipped, so I should be getting that in the next couple days. I will catch this thing. Whatever it is.
