Replacement glass dish for BBF1C Bluebird Feeder.  Complete with retainer ring that keeps the entire assembly off the base. 

The YCUP will fit into any of our barrier guarded feeders, and can be used in place of any internal feed dispenser. This feature allows your customers to install different feeding options in the same barrier guarded shell. Eg. use the YCUP for mealworms in spring and then switch to the YSUET in fall. Changeover is accomplished in seconds and without tools by simply loosening the large thumb nut at the bottom of the feeder shell. This quick disassembly feature also allows for quick cleaning of the feeder.   

The retainer ring is made by Erva in the USA. The glass dish is imported.
