The bird in a cuckoo clock is usually a carving or model of a Common Cuckoo. The Common Cuckoo is a species of cuckoo bird found throughout much of Europe, Asia and Africa. It is known for its distinctive two-note “cuckoo” call.
What is a cuckoo clock?
A cuckoo clock is a typically pendulum-regulated clock that strikes the hours with a sound like a common cuckoo’s call and has a mechanical cuckoo that emerges from a door or window on the clock face on each hour to ‘cuckoo’ the correct number of times to indicate the time. Cuckoo clocks are almost exclusively made in the Black Forest region of Germany.
The cuckoo clock was invented in 1730s or 1740s in Germany’s Black Forest region. Clockmakers developed the cuckoo clock as a way to keep track of time and incorporate an element of nature into clockmaking. The distinctive ‘cuckoo’ sound helped mark the passing hours in an era when most people did not have watches.
Main features of cuckoo clocks
Cuckoo clocks have several distinctive features and mechanisms, including:
- Pendulum – Long pendulum that swings back and forth, regulating the timing.
- Weights – Heavy weights that drive the clock movement through descent.
- Gear train – System of gears that transmit power from the weights to the clock dial.
- Bellows – Produces the ‘cuckoo’ sound.
- Automaton bird – Mechanical bird that emerges on the hour.
Additionally, cuckoo clocks often feature decorative wood carvings of animals, people, and scenes from Germany and Switzerland such as beer drinkers, couples dancing, or villages.
Origin and history of the cuckoo clock
The cuckoo clock originated in Germany’s mountainous Black Forest region in the early 18th century. Clockmaking was a thriving craft in the Black Forest area due to the availability of beech trees, which provided durable, lightweight wood. The region also had many long winter evenings when craftspeople could carve the components of cuckoo clocks.
While the exact origins are uncertain, the first cuckoo clocks were created around 1730-1750. Early models were relatively simple, wood-carved clocks with a cuckoo automaton. But clockmakers steadily added innovations like musical mechanisms, dancers, and bell-ringers.
By the mid-19th century, cuckoo clocks were widely produced for export around the world. Today, many Black Forest villagers, clockmakers, and shops continue the cuckoo clock tradition.

Common cuckoo bird
The Common Cuckoo is the species of cuckoo bird that typically appears on cuckoo clocks. Here are some key facts about this species:
- Scientific name: Cuculus canorus
- Widespread distribution across Europe, Asia, Africa
- Grey-brown plumage with lighter underside
- Distinctive ‘cuckoo’ call, males and females have different pitch
- Brood parasitic breeding habits
- Migratory species, winters in Africa
Physical description
The Common Cuckoo is a slender, long-tailed bird that measures 32–34 cm (12.5–13.5 in) in length and weighs around 100 grams (3.5 oz). Plumage is grayish-brown on the upperparts and lighter and more scaled on the underside. The wings are pointed. The tail is long with subtle white spots on the underside corners. The bill is an olive-yellow color.
Call
The Common Cuckoo’s most characteristic feature is its loud, ringing two-note call. The male’s call is usually described as “cuckoo” while the female makes a bubbling sound sometimes written as “bouteloup.” The call is often heard in spring and early summer.
Distribution and habitat
The Common Cuckoo has a very wide distribution across Europe, Asia, and Africa. Its breeding range extends from Britain across Scandinavia and southern Europe all the way to China and Japan. The northern populations migrate south to winter in sub-Saharan Africa.
Preferred habitats include open woodlands, heaths, farmland, parks, and gardens. The cuckoo occupies semi-open landscapes with lookout posts like wires or fence posts and nesting sites in low vegetation.
Brood parasitism
The Common Cuckoo is an obligate brood parasite, meaning it lays its eggs in the nests of other bird species. The female will watch a potential host bird and then lay an egg in the nest that closely matches the egg color and pattern of the host species. Some common hosts include meadow pipits, dunnocks, reed warblers, and pied wagtails.
Once hatched, the cuckoo chick will eject the other eggs or hatchlings from the nest. The host parents raise the cuckoo chick as their own, feeding it for up to 20 days until it fledges and leaves the nest.
Types of cuckoo clocks
While the traditional Black Forest cuckoo clock style remains popular, clockmakers now produce many different types of decorative cuckoo clocks in a variety of styles.
Chalet
Chalet style cuckoo clocks feature wood cases painted or carved to resemble alpine chalets or cottages with overhanging roofs and decorative eaves. These clocks often have painted scenes with people in Bavarian or Swiss dress.
Hunter
Hunter model clocks depict colorful scenes of hunters, game animals like deer or boar, and hunting dogs. The clocks may play hunting or shepherd’s horn music at intervals.
Musical
Musical cuckoo clocks incorporate elements like bells, a music box, or moving figures of dancers that perform to songs like The Happy Wanderer when the clock strikes. More complex musical clocks can play over a dozen tunes.
Modern
Modern cuckoo clock styles use newer materials like acrylics and metals and have minimalist, contemporary designs without the traditional wood carvings and motifs.
How cuckoo clocks work
Cuckoo clocks have intricate mechanical workings to produce the cuckoo call on the hour and move the automata. Here are the main elements that make the clocks work:
Weights
Traditional cuckoo clocks use cast iron weights ranging from 10-15 pounds on average. The weights are suspended via chains or cords that pass over a pulley and attach to gears. As the weights slowly descend under gravity, they power the clock movement.
Pendulum
The pendulum is a weighted disk or metal rod that rocks back and forth continuously. Each swing takes exactly one second, which regulates the timing of the clock’s internal mechanism.
Escapement
The escapement is a gear apparatus that converts the pendulum’s motions into rotational force that turns the clock hands at a controlled rate. It transmits the force from the weights to the gears.
Gear train
The gear train is a set of meshing gears that transfers power from the descent of the weights through the escapement and to the clock’s hands to keep time. The gear ratios control the hands’ speed.
Bellows
The bellows are a pair of flexible air chambers that produce the 2-note cuckoo sound. On the hour, a mechanism engages the bellows which ‘inhale’ and ‘exhale’ air across a reed, imitating a cuckoo’s vocalization.
Automaton
The cuckoo automaton is the moving bird model that emerges from a door to ‘cuckoo’ the hour. The automaton is made of carved wood. It moves when actuated by the clock’s mechanism at the top of each hour.
Modern cuckoo clock mechanisms
While traditional cuckoo clocks use purely mechanical parts and weights, modern clock technology also includes:
Quartz movements
Many modern cuckoo clocks run on quartz movements, which use an electronic quartz crystal oscillator and battery to regulate timekeeping instead of a pendulum and weights. Quartz movements make the clocks run more accurately.
Digital sound
Higher-end contemporary cuckoo clocks may have digital rather than analog sound. This generates a more accurate and realistic bird call sound.
Electric motors
Electric motors powered by batteries or AC current are sometimes used instead of weights to power the clock’s internal mechanisms and automata.
Conclusion
In summary, the bird in a cuckoo clock is a Common Cuckoo automaton. Cuckoo clocks originated around 1730 in Germany’s Black Forest region and are defined by their ‘cuckoo’ call and moving bird figurine that marks the hours. While traditionally carved and mechanized, modern cuckoo clock technology now incorporates quartz movements and digital features. Yet whether old or new in design, the cuckoo clock remains a symbol of German folk art, craftsmanship, and engineering.
