Sound.
It's egg units getting hit randomly at night. Some birds stay out at night etc.
There is a visitor's sign in book in a little shed. If I can I want fit a chair inside and bait a spot withing sight and possibly put a white board to possibly aid not illuminating the victim. Put a trail cam up and keep baiting hoping for a pattern to emerge.
Side note. I use to have PH safari in 308.
Got it cheap as "it won't shoot". By the time I finished with it it would put three rounds down the same hole!
I will get a box of kitty food when I get set up.
Thanks all.
