Description
Black Oil Sunflower is a popular seed that attracts a wide variety of birds. Its thin shell is able to be opened by virtually all seed-eating birds. The seeds contains a high crude fat content, a very important element for most winter birds. We recommend a large-port tube feeder, a hopper feeder or a feeder tray for this product. Black Oil Sunflower is available in 20# and 40# bags.
