KooKoo has given the cuckoo clock a new and modern design: clear, simple, and pure. The colorful birds and pendulums can be combined and easily exchanged as desired. At BirdHouse, a bird appears every hour and calls once or several times, corresponding to the hour. There are 12 authentic, naturally recorded songs of native songbirds and the call of the cuckoo to choose from. At night, the birds go to sleep. A built-in light sensor ensures a quiet night in the BirdHouse. Additionally, there are 4 colorful birds and 4 colorful pendulum discs for swapping, which are included with the clock.
