The Underneath Bird FeederTM is the only feeder that delivers black oil sunflower seeds from underneath the tube. This unique concept solves the problems customers complain about most -- squirrels, big birds and bad weather. No more stolen or moldy seeds! And since the seed is never exposed to bird droppings, it helps prevent the spread of bird diseases. And since birds pull only one seed at a time from the steel mesh and can't flick through the seeds, that means a healthy, cleaner feeding area and a lot less waste. The Underneath Bird FeederTM by Duncraft retails for $64.95.
