Cardinals, finches, and woodpeckers oh my! Feeding black oil sunflower seeds, (BOSS) will provide a great variety of birds in your backyard habitat. Mourning doves, grosbeaks, purple finches, house finches, gold finches, blue jays, chickadees, and most varieties of woodpeckers will all feast on BOSS.
BOSS has a thinner shell than other sunflower seeds, making it easier for small birds to crack open, and eat the heart. Compared to grey striped sunflower, BOSS has a higher oil content, making the hearts more nutritious, and calorie dense.
Hopper feeders, fly through feeders, and specific black oil sunflower feeders can be used with BOS
