Yellow headed woodpecker distress works well. Predators are very keen. Wind controll is a must. Coyotes and bobcats will usually circle a call to try and catch wind or sight of something try a moving lure and defiently you need good cover scent and quietness and stillness is a must. Move your stand about every 30 mis or so if no response. Always remember if one dog comes in another will show up shortly. So if one comes in and you miss the shot stick around another will show up.
