Lots of interesting ideas here. Yes, we have a wet weather creek through the property, and a good sized pond as well. We're actually thinking of putting up a game cam there, and on the trail where all the kills have been found. The issue with catching the predator(s) "in the act" is not the size of our spread, it's that we're only up there once a month or so. Once the cows get there, we'll have people on the place more often just to check in and make sure they're ok, but more often than not, there's simply no one out there to hunt the predators.
Some of our neighbors are also "absentee owners", so a sort of neighborhood watch for predators probably isn't going to happen. However, the wildlife technician for the area will be coming out to visit eventually, and I'll talk to him about it then.
The kills are always just off the trail, up in tall grass. I haven't looked for scrapes but didn't know to until I got back this week and started researching. There's not enough of the pelt left to reliably tell what sort of teeth went into it, but I can certainly check for large canine teeth marks (which would suggest a cougar).
If I go up next week to finish the gate, I'll try to remember to take my FIL's binoculars to scan the trees for bobcats. Unlike cougars, if there's a bobcat on or around, it's possible to find them during the day up overlooking their hunting spots.
No burros. I don't want to buy something that will try to run me off my own land, lol.
