The blackbird whistles. Whistle like him, by whistling four to six times with a soft "Co-co-co". You can also make short notes by aspiring with the mouth pursed. With this bird call, one can closely follow the blackbird's modulations and his long bursts of unbroken song. Made with beech 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.
