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). [Another model]

(!) ATTENTION, for this model that mimic a bird can be in trouble, (hunt for example), we ask you to tell us the details of a combination of nature conservation or other similar organization to which you belong and who can demonstrate your respect for nature and birds.
