Coyotes sound like foxes a bit; Have to call them in too mostly.
I have a mate with a scope (can't recall what) that cost him $7000AUD. Amazing at night. I think it's thermal rather than IR and has video recording also. I think I've seen your scope here, one of my other friends is a Vortex dealer and has a few other brands including an IR for around $800 which would be around $400USD.
Would love to head out your way and do some stalking. I'm reasonable at it but I think also it's fast becoming a dying art. Too much effort for the young kiddies.
