To imitate mouse and vole squeaks, place the o-ring, your teeth or lips at the outermost notch and blow with short thrusts in the call.
Distress calls from rabbit and hare
These calls are easy to make by placing the o-ring, your teeth or lips at one of the two notches in the middle of the mouth piece and blow into the call. The further back on the membrane the coarser the sound. Vary long and short sounds for 15-25 seconds and repeat every 3-4 minutes. Open and close your hand in front of the call’s opening as you blow for a more life like sound.
