Hi Christian,  I think the simplest solution for you would be to
contact MMM Mechanische Musikwerke Manufaktur GmbH, Rheinallee 7,
65385 Rdesheim am Rhein, Germany, tel.: +49 (0) 6722 47994
email: info@musicboxworld.de.geentroep [delete ".geentroep" to reply]

They are the current manufacturers of the former Griesbaum mechanical
singing bird boxes and bird cages, and you should be able to purchase
pre-made mechanical singing bird bellows and whistle assemblies
directly from them.

Alternately, you could also look on eBay for singing bird boxes and
bird cages for purchase and cannibalize the mechanisms from them for
use in your automation.  However, those on eBay often require some
repair or restoration before they are functional.

Please let me know if I may be of any further service to you.

Most sincerely,
