you need something moving to draw their attention, I had one of those battery powered wiggly tail things ha ha I don't know what their called but I pull the little squeaker out of small dog toys and hold that in my lips like a mouth call and it worked twice so far,,,, I put the wiggly thing at the best shot angle where I'm shooting through a lane or between trees set it inside the brush so they can't really see it that good which brings em in closer but it really draws their attention especially if its brushing against a leaf when it spins and seems to work the best,,,,, I'm hunting urban coyote and coyote calls did nothing but they love that little ball squeaker it sounds like a mouse caught by something.
for camo I wear a ghilly suit but had a leafy suit when I shot the first one...... shot two from a stand and one from the ground,,,,,,, one coyote did come in on a fawn bleat I was actually hunting deer that day it was a primos fawn bleat.
