To make the Sparrow call, do not blow. Just lower the bird call in one hand and then with the other squeeze to give small discrete moves. Take the pace, especially with every sparrow. Made with leather and metal.

These beautiful hand made bird calls have been made in France since 1970 and are put together using natural sustainable products. Each birdcall is presented in a handmade wooden box with a sketch of the bird and instructions for use printed inside.
