Fluid inside condenses from the evaporative cooling of the water off the birds beak, making it top heavy and dunking it back into the water. The condensate rejoins the liquid pool in the birds bulb, and he tips up again. Process continues indefinitely.
It works, but its not any more than moderately well made, and not any more than moderately priced. WARNING! The fluid and dye inside the bird can permanently stain, and the birds glass body can easily be broken.
Children are fascinated by the bobbing bird, and the educational possibilities are great. But they should watch it, not fondle it!!
