Expand Your Calling Arsenal
One key to successfully calling shy ducks is diversifying your calls. Kelly Haydel of Haydel's Game Calls suggests adding a variable tone call that allows you to do a short series of old hen calls combined with a series of young hen calls, which provides a more natural sound. Mixing in a pintail whistle is an excellent finisher. Rene Dandry of Louisiana Delta Outfitters likes to combine a gadwall call and a whistle, a pairing that has worked well for him when hunting call-shy birds.
