How to Make a Moose Call Out of Birch Bark

Harvest a piece of birch bark. Look for a dead tree and scrape or peel off the damp inner layers to find the pink bark beneath. Harvest a piece of bark from a tree about 9 inches in diameter.

Create a funnel shape. Roll the bark into a funnel shape with the white outer bark on the inside. Secure the corner of the bark to the funnel with a self-tapping screw about 1/2 inch from the edge.

Trim the ends. Trim several inches off both ends with a band saw to make the openings even.

Drill threading holes. Drill a series of holes about 3 inches apart along the outer edge of the bark where it overlaps on the outside of the funnel. Drill through two layers of bark.

Reinforce the large end of the funnel. Use the razor knife to cut a strip of bark about 1 inch wide and long enough to fit around the larger end of the funnel with about a 1 inch overlap. Wrap the strip around the outside of the funnel end and secure with a self-tapping screw. Drill a series of holes about 1 inch apart through the funnel right next to the strip.

Secure the funnel with the leather or moose hide cord. Sharpen the end of the cord with the razor knife and knot the opposite end. Start at the narrow end of the funnel and thread the cord in and out of the holes drilled along the outside edge. Finally, thread the cord over the reinforcing strip and around the outside edge at the large end of the funnel. Secure with a knot when finished and trim the end.
