How a rooster sound is produced in a clock

An interesting and lively thread on The Automata / Automaton Facebook Group page started by artist Aaron Kramer has to do with means for producing the sound of a crow. Not wind-generated method, but a mechanical one. Among the many wonderful responses, this video was posted by the automaton-maker Thomas Kuntz.

The video explains the clever mechanism within a rare musical clock that is used to create the sound of a rooster on the hour. The clock was made by Emilian Wehrle of Furtwangen, Germany around 1890. The video is from www.blackforestclocks.org
