Cuckoo Clocks

Cuckoo Clocks

A cuckoo clock is a clocl, typicallypendulum - regulated, that strikes the hours with a sound like a common  call and typically has a mechanical cuckoo that emerges with each note. The mechanism to produce the cuckoo call was installed in almost every kind of cuckoo clock since the middle of the 18th century and has remained almost without variation until the presentree thing that is unique about some quartz cuckoo clocks is that they include a light sensor, so that when the lights are turned off at night they automatically silence the hourly chime. Other quartz cuckoo clocks are pre-programmed not to strike between a set of pre-determined hours. Whether this is controlled by a light sensor or pre-programmed, the function is referred to as a 'night silence' feature. On quartz clocks the weights are conventionally cast in the shape of Aleppopinecones made of plastic rather than iron, as are as the cuckoo bird and clock hands. The pendulum bob is often another carved leaf. The weights and pendulum are purely ornamental as the clock is driven by battery power. As with mechanical cuckoo clocks, the dial is usually small, and typically marked with  made of plastic rather than iron, as are as the cuckoo bird and clock hands.

Instead of the call being reproduced by the traditional bellows, it is a digital recording of a cuckoo calling in the wild (with a corresponding echo). The cuckoo call is usually accompanied by the sound of a waterfall and other birds in the background
