Fill your favorite backyard bird feeder with sunflower seeds and wait for birds with cone-shaped bills to swoop in for lunch. Birds like northern cardinals, rose-breasted grosbeaks, evening grosbeaks and purple finches have thick, short beaks designed for breaking open seeds with ease. Here’s how to choose the best sunflower seeds for birds.

Black-Oil Sunflower Seed

Sunflower seeds are an ideal snack for many birds. There are two types of commercial sunflower seeds. Oil seed (known as black-oil sunflower seed to backyard birders) is small, black and processed for sunflower oil. Black-oil sunflower seed is the pizza of bird food: Nearly everyone in the backyard will enjoy it. It’s an ideal option if you have space for only one feeder. These seeds have fatty meat and a thin shell for easy feasting.

A seed preference test performed by the Cornell Lab of Ornithology showed that the majority of feeder birds prefer high-fat black-oil sunflower seed. It’s simple to serve, too—spread it right on the ground or fill up a tube, tray or hopper feeder. The seed is popular with most birds that winter in the northern regions and is typically easy to find in feed stores or even grocery stores.

Striped Sunflower Seed

Non-oil seed is larger, black and-white striped and used in food. These are the same kinds of seeds you may eat as a healthy snack—but make sure they’re unsalted and unseasoned if you want to share with your feathered friends. Striped sunflower seeds are hearty but tougher to crack. Because the seeds are less fragile than black oil sunflower, birds may have a harder time cracking them open easily.

With both of these types of seeds, sunflower seed shells may collect on the ground under your feeders, and there’s no need to remove them right away. Many birds are more comfortable feeding on the ground, and they’ll rummage through the shells looking for morsels that other birds have missed. But if the debris is more than an inch or two deep, you should remove it and add it to your compost pile, since it can get moldy or spread diseases.

If you’re trying to attract birds to a balcony or if you just don’t want the mess of seed shells on your lawn and garden, sunflower seed hearts or chips (small pieces) might be a better choice for you.

You may also attract birds like wrens that have trouble cracking open seeds. There’s no waste, and birds don’t have to use extra energy to get to the food.
