The Best Bird Seed for Camera Feeders: What to Buy, What Each Seed Attracts and What It Costs

The seed you put in a smart bird feeder decides which birds show up on camera, how messy the tray gets and how much the feeder costs to run over a year. Most camera feeders are small hoppers in front of a lens, so the choice matters more than it does with a big tube feeder in the back corner of the yard.

We haven’t tested seeds ourselves. What each food attracts comes from the Cornell Lab’s Project FeederWatch food guide and All About Birds; prices are what Amazon showed on November 12, 2026, converted to cost per pound.

The short version

Black-oil sunflower: the default

Project FeederWatch calls black-oil sunflower the most common feeder seed in North America and the preferred food of a wide variety of birds. It’s high in energy, its thin shells are easy for small birds to crack, and it’s a favorite of cardinals, chickadees, finches and sparrows; even woodpeckers take it occasionally.

For a camera feeder, it’s also the most economical. A 25 lb bag of Wagner’s black-oil sunflower was $41.98 on Amazon on November 12, 2026, about $1.68 per pound. That’s the price our true cost calculator uses by default.

The downside is shells. They pile up on the tray in front of the lens and on the ground below. FeederWatch recommends raking up waste under feeders regularly, because it can harbor pathogens and attract rodents.

Sunflower hearts: worth it for small hoppers

Hulled sunflower (“hearts and chips”) is the same seed without the shell. FeederWatch notes any bird that eats sunflower will take it, many prefer the easy meal, and there’s far less chaff. The catch: it spoils faster, so keep it dry.

Hearts make the most sense in small camera feeders. The Birdbuddy Pro Solar and Nook Solar hold only 0.9 L, and shells take up room and clutter the frame. Morning Song Sunflower Hearts & Chips worked out to about $2.78 per pound on November 12, 2026, so you pay roughly 65% more per pound, partly offset by not paying for shells.

Safflower: cardinals yes, squirrels mostly no

Safflower is a white seed that big-billed birds like cardinals take readily. All About Birds notes it has limited appeal for squirrels, which makes it a smart switch when your camera keeps recording squirrel raids. FeederWatch’s caveat is honest: most birds still prefer sunflower, so a safflower-only feeder usually shows fewer species.

Pennington Select Safflower, 15 lb was about $1.80 per pound on November 12, 2026. A common approach is to mix it with sunflower and shift the ratio toward safflower when squirrels or grackles take over. Our squirrel-proof feeder guide covers the hardware side.

Nyjer: great finches, awkward in camera feeders

Nyjer (often sold as “thistle”) is the goldfinch and Pine Siskin seed. FeederWatch says it needs a feeder with very small ports to prevent spillage and is best fed on its own, not in a mix.

That’s the problem: most camera feeders have open trays. Nyjer’s tiny seeds blow and spill out quickly. If goldfinches are your goal, hang a small-port finch feeder in view of the camera, or use a feeder with a split hopper so you can keep nyjer in a contained compartment. The Kiwibit Solar 4K has a two-compartment 1.5 L hopper, which The Gadgeteer noted lets you offer two seed types.

Suet: for the birds that don’t eat seed

Suet is rendered fat for insect-eating birds: woodpeckers, nuthatches, chickadees and wrens. FeederWatch warns that ordinary suet can go rancid in hot weather unless it’s specially processed, so use no-melt dough such as C&S Hot Pepper Delight in summer; the hot pepper also tends to put squirrels off while birds eat it normally.

Most camera feeders don’t hold suet cakes, so add a cage next to the feeder or a holder that clips on. Bird Buddy feeders take a third-party suet ball holder beside the perch.

Mealworms: the bluebird trick

FeederWatch calls mealworms one of the only foods that reliably attracts bluebirds, and chickadees, titmice, wrens and nuthatches relish them. Dried mealworms work in most tray-style camera feeders. They’re the priciest food per pound (about $6.80 for a 5 lb bag), so offer a small handful at a time.

Millet and mixes

White proso millet is loved by juncos, sparrows and doves that feed on the ground. It also draws House Sparrows and cowbirds, so offer small amounts on a low tray or the ground rather than filling a camera hopper with it. Avoid mixes heavy in milo, the reddish round grain FeederWatch says most birds (particularly in the East) leave to waste.

Nectar for hummingbird feeders

Hummingbird camera feeders like the Birdfy Hum 2K and Humbirdy 4K take sugar water. Audubon’s recipe is 1/4 cup of refined white sugar to 1 cup of boiling water; never use honey or red food coloring. Plain sugar is the cheapest option by far; dye-free ready-to-mix nectar is a convenience.

Matching seed to your feeder

• Small hoppers (0.9–1 L): Bird Buddy Pro, Nook, Kiwibit 2 Mini. Use sunflower hearts to cut mess and refill often.
• Mid hoppers (1.4–1.8 L): Birdbuddy Home, Birdfy Feeder 2 series, Birdfy Metal 2 4K, birdsnap TUC. Black-oil sunflower, plus safflower if squirrels are an issue.
• Big hoppers (2.7–3.2 L): Soliom BF08, Perky-Pet. Bulk black-oil sunflower is the economical choice.

What seed costs over a year

Seed, not the subscription, is often the biggest running cost of a busy feeder. At $1.68 per pound, a feeder going through 5 lb a month costs about $100 a year in sunflower; 10 lb a month is about $200. Plug in your own usage in the true cost calculator to see seed alongside each feeder’s subscription.

Find the right food for your region

Which seed is “best” also depends on who lives near you. Enter your region and season in the Which birds will I attract? tool to see likely visitors for each food, or read our winter feeding guide for cold-weather changes and our tips on attracting birds to a new feeder.
