The call of the cuckoo-clock bird is heard from nearly every window in the village deep in the Black Forest.

Schonach is the capital of the world's cuckoo-clock industry, which is centered here and in the surrounding villages of Triberg, Furtwangen, Schwenningen and Villengen.

Last year 1,000 Kuckuck Urh Machers - cuckoo-clock makers turned out 700,000 hand-carved cuckoo-clocks, 80 per cent of which were shipped to 70 countries around the world. One of every seven cuckoo clocks produced here was sold in the United States.

Factory prices for the clocks begin as low as $20 and go as high as $1,000 each. Retail prices in America are three to four times that.

Cuckoo clocks have been the exclusive product of the Black Forest ever since a farmer in Furtwanger with nothing else to do in the winter of 1640 created the first of the clocks with the little bird that pops out and sings out the hour.

There are 15 cuckoo-clock factories. Some employ as few as 10 persons and others as many as 70. All the factories get the movements for the clocks from the same factory in the Black Forest.

The face of the cuckoo clock is usually the traditional hunting scene - a deer with antlers on top, a hunting gun, powder bag and horn, a rabbit and a pheasant all hand carved out of Linden wood. The carvers follow the craft of several generations before them.

The cuckoo call comes from a pair of bellows, made from goatskin. Women in the villages have been making the cuckoo clock bellows in their homes for three centuries.

The cuckoo-clock factories where the clocks are assembled have been in the same families for generations.
