Drinking birds, also known as dunking birds, drinky birds, water birds, or dipping birds [1] [2] [3] are toy heat engines that mimic the motions of a bird drinking from a water source. They are sometimes incorrectly considered examples of a perpetual motion device.
The story concerns a thirsty crow that comes upon a pitcher with water at the bottom, beyond the reach of its beak. After failing to push it over, the bird drops in pebbles one by one until the water rises to the top of the pitcher, allowing it to drink.

Common ravens can be observed in oceans consuming water. However, when birds consume salt loaded prey or drink salt water, the body’s internal osmoregularity increases. The solution produced is considerably more concentrated than seawater. [37] Birds are the only group of vertebrates that have the ability to produce hyposmotic urine.
Albatrosses, along with all Procellariiformes, must excrete the salts they ingest in drinking sea water and eating marine invertebrates. All birds have an enlarged nasal gland at the base of the bill, above their eyes. This gland is inactive in species that do not require it, but in the Procellariiformes, it acts as a salt gland. Scientists are ...
The American dipper's nest is a globe-shaped structure with a side entrance, close to water, on a rock ledge, river bank, behind a waterfall or under a bridge. The normal clutch is 2–4 white eggs, incubated solely by the female, which hatch after about 15–17 days, with another 20–25 days to fledging. The male helps to feed the young.
But using the drinking bird method, scientists have managed to generate an output of 100 volts using just 100 millilitrers of water, enough to power small electronic devices.
