The heat generated by the lamp (conversion of electrical energy into thermal energy) warms the liquid in the bird's stomach, expands and rises into the bird's body. This causes the bird to shift its center of gravity and tilt forward. The energy the bird contains due to its movement is also known as kinetic energy. The returning fluid and a renewed supply of heat cause the bird to bounce back and forth.
