As the liquid rises, the bird becomes top heavy and tips over. When the bird tips over, the bottom end of the neck tube rises above the surface of the liquid in the bottom bulb. A bubble of warm vapor rises up the tube through this gap, displacing liquid as it goes.

A 6″ bird with a felt covered head and has plastic feet who cannot get his fill of water. You buy the drinks.
