Most wall cuckoo clocks are made in the Black Forest region of Germany, in the style of either a chalet, or in the traditional style with carved leaves and animals. As the clock strikes the hour, or half hour, an automaton cuckoo appears from behind a trap door, the sound of the cuc-koo being reproduced by a pair of bellows. Cuckoo clocks are nearly always weight-driven, with either two or three distinctive pine cone weights. They do however exist as spring-driven mantel clocks.
Many of our reproduction cuckoo clocks have musical movements, and play a tune on a music box after striking the hours and half-hours. This may also be accompanied by other automata, for instance a woodchopper, or a beer-drinker; others have dancers.
