Probably the most commonly used bird seed, birds eat sunflower seed due to its high fat content. There are primarily three sunflower seed options; black-oil sunflower, striped sunflower, and hulled sunflower. Black-oil sunflower seed is eaten by more birds than striped sunflower seed due to its smaller size and easier to crack shell. Though striped sunflower seed will still be eaten (and may be preferred) by larger bird species like Blue Jays and Woodpeckers. Hulled (shell removed) sunflower seeds attract the greatest number of bird species because they are easiest to eat, especially for birds who don’t have the beak strength to crack shelled sunflower seed. While hulled sunflower seed is the most expensive, it does not make the mess the shelled varieties often make.
