Bird Water Whistle - Economical 4 pack. Fill them with water and blow into them to make a wonderful bird 'chirping' sound. For the best results, fill the whistle with water to 1/2 way.
Advantages of The Bird Water Whistle include:
The sound this whistle generates is very reinforcing
May be used to develop fine motor skills (emptying and filling)
Encourages grading of air flow and provides a goal for the child (if blown very hard water will bubble out of the bird's mouth)
