The thrush is simply mimics
Since you have to hit the bottom of the bird call low blows,
Gently, "Tic, tic," or "Trip, trip ...."
But beware! The Thrush is a musician.
In the south, many farmers require some thrushes "Tourdre" (Latin  Turdus = Thrush)

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.
