I would recommend some light cow calls, just some little mews.... spot them and then infiltrate with some light cow talk. Where good matching camo (matches your area) and make sure to be scent free, and a little extra cow scent on the boots would also be good. And also get one of those little air checker bottles (little puff bottles full of whiteish powder) and keep the wind in your face.

That should be a good starting point, Good luck!!!
