Any farm / ranch area with good cover and water.
I hunt in Socal where there is a lot of cattle and deer, but most often where there is a lot of rodents (ground squirrels & rabbits) !
Go to extactly where you see them in full camo, including a head cover and gloves.
Pattern their movements in the area and learn how to best plan your final approach.
Otherwise, all you will do is educate them - understand, because they do !!!
Set-up in good cover with a good view, especially down wind of your location.
You would be wise to bring a low slung chair or at laest a cushion, so you can remain motionless for extended periods of time.
Put a stick and strink with a turkey feather on it(any decoy will help) about 100 feet out front & upwind of your location.
Call softly until you get better...................they'll know exactly where the call is coming from, so no need to continuing calling once you see them (remain motionless).
You must see them before they see you !!!
Bring shooting sticks so you can prop your gun on them to steady your shot.
1 in 10 attempts is good for a hawk getting a mousse, so don't get discourged
