The drinking bird is a heat engine that exploits a temperature difference to convert heat energy to a pressure difference within the device, and performs mechanical work. Like all heat engines, the drinking bird works through a thermodynamic cycle. The initial state of the system is a bird with a wet head oriented vertically.
After the bird’s beak is dipped into a cup of water, it springs back into its natural upstanding position, and the water begins to evaporate and cool the head.
