Black oil sunflower seed is the most popular bird seed among a wide variety of backyard birds, and most birds will at least sample the seeds even if they prefer other foods. Sprinkle the seeds directly on the ground or put them in a hopper, platform, or tray feeder. The soft shell makes it suitable for small songbirds.
This wild birdseed is a good source of quality protein and has a high concentration of oil. This is particularly important in the winter when birds will spread oil from their oil glands over their feathers to keep them buoyant, dry and warm.
