The selection of the cuckoo as the representative bird for clocks has several reasons. An important factor is the presence of this species in the area where clocks originated. The term 'cuckoo' generally refers to birds of the Cuculidae family, which includes over 140 different types. Among them, the common cuckoo (Cuculus canorus) stands out, known for emitting the characteristic 'cuckoo' sound and inspiring cuckoo clocks.
The common cuckoo is a migratory bird that can be found in Europe, Asia, and parts of Africa. It is particularly frequent in the Black Forest, a region of Germany where cuckoo clocks were developed. This bird migrates away during the German winter and returns in the warmer months, establishing a link between its song and the arrival of spring.
Another relevant aspect is the simple nature of the cuckoo's song. Its sound consists of only two notes: a higher one followed by a lower one. This simplicity facilitates the mechanical replication of this sound, as occurs in clocks. Traditional models use a bellows mechanism that directs air through wooden whistles, generating these two distinctive notes.
Although the precise origin of cuckoo clocks remains uncertain, it is known that their production and commercialization became popular in the mid-18th century, serving as an additional source of income for artisan peasants in the Black Forest. Clockmaker Franz Anton Ketterer is cited as one of the possible inventors of the cuckoo clock, although this hypothesis has not been confirmed.
In summary, the song of the cuckoo bird combines desirable elements in a sound that marks time: it is easy to mechanically replicate, is linked to the passage of time, and has a short and simple duration, avoiding auditory boredom.
