Terracotta Tweet Bird. Fill these bird-shaped whistles with water and blow! Whistles that make birdsong sounds and beautifully mimic the actual sound of Real Bird Singing. If you blow through the stem of the EMPTY bird, no sound will come out. Then fill the bird’s tummy half with water and on blowing now the bird will whistle. How does the birds whistle? All sounds from a guitar or a car are sound waves that travel through and reach our ears through vibrations. The bird’s whistle is no different. It works through vibrations in the air inside the bird. As you blow through the bird’s tail the air is split by a narrow blade. This creates a turbulent vortex and causes the air to vibrate. The bird’s tummy which is the resident chamber makes the sound louder. You can alter the pitch of the sound by lowering or raising the bird.
