I think if it was on all the time or was automatic, they'd learn to ignore it. They stop and scatter because it's us, and we often yell too. You remember all the issues I had with shooting them. They're still issues... and at this point, we haven't seen them when they party like that... not even eyes. Too much brush and undergrowth.
I talked to the trapper on the phone after the other sightings when they were getting bold. He said he could come out and set traps, but that coyotes can be crafty and hard to trap and it might take a while. Honestly, I still feel that we'll never eliminate them, I just want to keep a good fence between them and the dogs, a good sense of fear in them about letting themselves be seen, and the kittens will either have to learn to stay in the compound or stay within a short sprint of a tree. That's just the way it is.
That makes sense. I don't have too worry about dangerous critters too much. Every now and then we'll get a raccoon or a deer in the yard.
Mostly its tree-rats and voles/moles that cause me grief. And the occasional mouse.
