ABSTRACT:
An abrasive surface is provided on the feeding surface of a bird feeder pan. Thus as the birds eat, their beaks are abraded and trimmed. This controls the growth simultaneously with feeding the birds. The abrasive surface includes abrasive particles bonded to the feeding surface directly or may be bonded to the carrier which is adhered to the feeding surface.
