The original iconic A-6F Classic Bird Feeder was brought back in 2015 from its five year retirement. In 1969, Droll Yankees founder Peter Kilham invented the very first tubular bird feeder, the A-6F. Over one million A-6F feeders later, this feeder remains a classic. If one of your childhood memories is feeding and watching birds at home, chances are your family owned a Droll Yankees bird feeder!
