My new Mole Killer

[Setter Man]

I’ll catch a couple on trail cams and occasionally see one dart across a two-track. Pretty cool to know they are out there but I’m guessing they have an impact on the grouse population.

[C.O.B.]

I think their impact on the grouse population isn't any greater than any other predator be it a fox, raccoon, hawk or owl. The grouse population where I deer hunt is actually increasing and I've seen three bobcats there in the last couple of years. They need to make a living in the woods just like any other inhabitant.

I couldn't say with any authority, but I think their diet is primarily vermin, Though I'm positive I saw one trout watching.
When I mow one field which only gets cut once per year, they, and fox, will be seen just watching for field mice.
