KooKoo has given the cuckoo clock a modern design: clear, simple, and pure in black or white. The colorful birds and pendulums can be combined and easily exchanged as desired. KooKoo brings nature into the home. At BirdHouse, a bird appears every hour and calls once or multiple times, depending on 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 peaceful night in the BirdHouse.
