before you ever go look at arial and topo maps... look for ag fields near by, ridge tops, hollow, secluded pastures, points, and flats
if its a large property start early on a high listening spot and move when the birds sound off
if its smaller and not a lot of room to move, find a open feeding or strut zone, (field, pasture, clearcut, open flat or ridge top) and set up. if you dont hear or see much after a few hours take a walk around the property calling every 75yds. look for tracks, droppings, roost trees, dusting bowls, food (acorns, clover, berries)
