Selecting realistic decoys and then arranging them properly into a natural-looking spread is only the first step in successful goose hunting. The next is calling to and finishing a flock of honkers; the game can be lost with the first note given to distant birds en route to feed or water or up-close when they're finishing.
Being able to vary the sounds a single call makes adds realism to your set up by making it seem as if more than one bird is sounding off. The key is to change the tone, pitch and volume of your calling.
In this video, Bill Saunders, one of the country's best goose callers, shows you how to hold and blow a short-reed goose call effectively by simply adjusting how you hold the call.
