How To Make A DIY Birch-Bark Horn For Calling?

Preparing the Birch Bark

When selecting birch trees, look for those with smooth, thin bark that is easily removable. Typically, paper birch (Betula papyrifera) or yellow birch (Betula alleghaniensis) work well. Harvest the bark in the spring or early summer when it is most pliable. Use a sharp knife to cut the bark into manageable pieces, about 1-2 inches wide and 8-10 inches long. Soak the bark pieces in water for several hours to make them more pliable.

Shaping the Horn

To shape the horn, use a drill or a knife to create a conical shape, about 4-6 inches long and 1-2 inches in diameter. Hold the bark piece over a candle flame or a heat source to dry and shape it further. Alternatively, use a hot knife or a heated metal rod to shape the birch bark. Be cautious not to burn the bark, as this will compromise its integrity.

Adding a Mouthpiece and Blowing Reed

To create a functional horn, add a mouthpiece and a blowing reed. Cut a small notch in the top of the horn and attach a piece of thin wood or a reed to serve as the blowing reed. Add a mouthpiece made from a small piece of wood or antler, about 1/4 inch in diameter and 1 inch long. Attach the mouthpiece to the horn using a small amount of beeswax or plant resin. When blowing into the horn, aim for a moderate pitch, around 250-300 Hz, which is suitable for moose calling.
