If you’re looking for an economical triple tube feeder, look no further! This Woodlink feeder has fully looped perches and a tray making it easier for the birds to feed and look for predators. It also features polycarbonate tubes for long lasting clarity. Since most all seed eating birds can feed from this feeder, we recommend that you offer black oil sunflower seed in one tube, shelled sunflower chips or hearts in another, and safflower in the third. This will really please cardinals and ALL seed eating birds love shelled sunflower chips!
