Audio file for stimulating and training the singing of warblers to sing with great vigor. 💡 How to use effectively: Turn the volume to a moderate level for the bird to listen to each day (about 30-45 minutes). Avoid turning it up too loud, as this may scare or stress the bird. Combine with a regular diet and sun exposure for best results.
