Hand calling is difficult, but can give you greater flexibility in calling and communication with the birds. Place the call between your thumb and index finger, making a cup around the end with your hands. Rather than blow through, you will want to make a growling noise into the call, as if you were clearing your throat. [4] X Research source
You can also create an artificial structure if you do not have enough natural spaces. Drive or set poles into the ground, then place a cross-bar between them for more roosting room. [7] X Research source
