The design of a cuckoo clock is now conventional. Most are made in the "traditional style" (also known as "carved") or "chalet" to hang on a wall. In the "traditional style" the wooden case is decorated with carved leaves and animals. Most now have an automaton of the bird that appears through a small trap door while the clock is striking. The bird is often made to move while the clock strikes, typically by means of an arm that lifts the back of the carving.
There are two kinds of movements: one-day (30-hour) and eight-day movements. Some have musical movements, and play a tune on a Swiss music box after striking the hours and half-hours. Usually the melody sounds only at full hours in eight-day clocks and both at full and half hours in one-day clocks. Musical cuckoo clocks frequently have other automata which move when the music box plays. Today's cuckoo clocks are almost always weight driven, though a very few are spring driven. The weights are made of cast iron in a pine cone shape and the "cuc-koo" sound is created by two tiny gedackt (pipes) in the clock, with bellows attached to their tops. The clock's movement activates the bellows to send a puff of air into each pipe alternately when the clock strikes.
In recent years, quartz battery-powered cuckoo clocks have been available. As on mechanical cuckoo clocks, the cuckoo bird emerges from its enclosure and moves up and down, on some quartz clocks it also flaps its wings as it calls, but instead of the call being reproduced by the traditional bellows, the call 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 water fall and other bird call in the background. During the cuckoo call the double doors open and the cuckoo emerges as usual, but only at the full hour, and they do not have a gong wire.
