{wiki=Drinking_bird}
A drinking bird is a novelty toy that simulates the action of a bird drinking from a water source. It typically consists of a plastic or glass figure resembling a bird, with a long neck and a beak that dips into a container of water. The bird is filled with a liquid, often colored, and has a temperature-sensitive mechanism that allows it to oscillate back and forth, creating the appearance of drinking. The drinking bird operates based on principles of thermodynamics and vapor pressure.
