Each mount is cnc machined from a block of Delrin personalised with your phone number aiding in the quick return of a lost bird.  The Artisan tail mount also has a clever feature that enables a bell to be mounted using a small cable tie held in place by a special designed holder.  This means that the bell is not connected to the leather bewit fixed to the deck feathers. also a bell can be added or removed without the need of taking off the tail mount.   Please tell us the species and sex of the bird the mount is for in the drop down options.
