Which wild bird food to buy for your garden birds

Part of our guide on choosing food for small birds

Most garden birders waste half their seed buying mixes stuffed with milo and wheat that only pigeons and house sparrows want.

Match the seed to the beak

Say you fill a feeder with a grocery-store mix and half of it lands on the ground by evening. The birds are tossing out the milo, wheat, and oats to get at the sunflower seeds underneath. Those filler grains are cheap, but most desirable backyard birds cannot crack them or simply ignore them. You are paying for waste.

Black-oil sunflower seed has a thin shell and a high oil content. Chickadees, titmice, finches, cardinals, grosbeaks, nuthatches, and jays crack it easily. Even smaller birds like goldfinches will take it if nothing else is available. A 25-pound bag of straight black-oil sunflower draws 15 or more species and costs less per pound than a mixed bag of the same weight.

Suet cakes are rendered beef fat, often mixed with seeds, nuts, or insects. Woodpeckers, nuthatches, Carolina wrens, and chickadees eat them year-round. Suet provides the high-calorie fat these birds need, especially during migration and winter. A no-melt formula works in summer without turning rancid or dripping.

White proso millet is the other seed worth buying. It is smaller than sunflower and appeals to ground-feeding birds like juncos, sparrows, and doves. If you scatter millet on the ground or in a platform feeder, those species show up. Tube feeders are the wrong place for it. Before you commit to anything, it is worth looking at what household foods can birds eat.

Nyjer seed, also called thistle, is tiny and loved by goldfinches and pine siskins. It needs a specialized feeder with small ports. If you do not see goldfinches regularly, skip it. The seed is expensive and ignored by most other species.

Buy by the bag, not the box

Picture a 5-pound bag of wild bird seed at a grocery store for nine dollars. That is $1.80 per pound. A 25-pound bag of black-oil sunflower from a farm-supply retailer or an online seller runs around $20 to $25, or $0.80 to $1.00 per pound. You are paying less than half per pound, and the larger bag lasts a month or more for a household running two or three feeders.

Bulk bags also let you control what you are buying. Small boxes are nearly always mixes, and the ingredient list hides how much filler you are getting. A 20 or 40-pound bag of straight black-oil sunflower or white millet is exactly what the label says. No surprises. If that sounds like your situation, read up on 40 pound seed for birds next.

Online sellers ship 20 to 50-pound bags with delivery included in many regions. Farm-supply chains and feed mills sell the same sizes in-store, often for a dollar or two less per bag than online. A feed mill also stocks cracked corn, whole peanuts, and other single-ingredient feeds if you want to experiment.

Suet cakes are sold in packs of 10 to 20. Buying a variety pack with different flavors (insect, nut, berry) lets you see which formula your woodpeckers prefer. Store unopened suet in a cool, dry place. It keeps for 6 to 12 months if the packaging is intact.

• Online: search for 20 to 40-pound bags of black-oil sunflower or no-melt suet packs. Delivery is included or flat-rate in most cases.
• Farm supply stores: Tractor Supply, Rural King, and regional chains stock 25 and 40-pound bags year-round at competitive prices.
• Feed mills: local mills sell by the bag and often at a few cents less per pound than chain stores. Call ahead to confirm they stock black-oil sunflower.
• Big-box stores: Home Depot and Lowe's carry 20-pound bags in spring and fall, but selection shrinks in summer and winter.

How to identify the right bird food for common garden birds

Say you hang a feeder and see a mix of small brown birds, a few red cardinals, and a woodpecker. That tells you what to stock. The small brown birds are likely chickadees, titmice, or sparrows. Cardinals need something they can crack with a heavy beak. Woodpeckers want fat, not seed.

Chickadees and titmice take black-oil sunflower from tube or hopper feeders. They also eat suet. If you have both, they visit all day. Cardinals, grosbeaks, and jays crack sunflower easily and prefer platform feeders or large perches on hopper feeders where they can land and shell seeds without clinging. Finches (house finches and purple finches) also take sunflower from tube feeders, and goldfinches prefer nyjer if you offer it in a dedicated feeder.

Woodpeckers, nuthatches, and wrens are after suet. Downy and hairy woodpeckers, red-bellied woodpeckers, and flickers visit suet cages. Nuthatches take both suet and sunflower seeds, so they show up at multiple feeders. Carolina wrens, common in the Southeast, eat suet but rarely touch seed.

Ground feeders (juncos, native sparrows, doves, and towhees) prefer white proso millet scattered on the ground or in a low platform feeder. They rarely visit elevated tube feeders. If you see these birds hopping under a feeder, they are cleaning up spilled seed. Offering millet directly saves them the trouble and reduces waste.

Identify your visitors for a week and stock the seed they actually eat. If you never see goldfinches, skip the nyjer. If cardinals and jays dominate, a 25-pound bag of sunflower and a hopper feeder are enough. If woodpeckers are common, add a suet cage and restock it every two to three weeks.

Where to buy wild bird food online or locally

Online sellers ship bulk bags with tracking and flat-rate or included delivery. Search for black-oil sunflower in 25 or 40-pound bags. Major retailers and bird-supply specialists both stock it. Delivery takes two to five days in most of the US. Suet packs and nyjer seed ship the same way, though suet may cost more to ship in hot weather because of the need for faster delivery or cold packing.

Farm-supply stores (Tractor Supply, Rural King, Fleet Farm) carry 20, 25, and 40-pound bags of black-oil sunflower, millet, and cracked corn year-round. Prices run $18 to $28 for a 25-pound bag depending on the season and your region. Suet cakes are stocked near the seed, usually in 10-packs. These stores also sell feeders, so you can pick up a tube or hopper feeder and seed in one trip.

Feed mills and co-ops sell bird seed by the bag or in bulk by the pound. A mill often has the lowest per-pound price in your area, sometimes as low as $0.70 per pound for black-oil sunflower in 50-pound bags. Call ahead to confirm they stock it, because some mills focus on livestock feed and carry limited bird seed. Bring your own container or buy bags at the mill.

Big-box home-improvement stores (Home Depot, Lowe's, Menards) stock 20-pound bags of black-oil sunflower and mixed seed in their garden sections from March through October. Selection shrinks in winter, and prices run slightly higher than farm-supply stores. Suet is stocked inconsistently.

Local bird-specialty shops carry premium seed mixes, suet, and feeders, along with advice on what works for your region. Prices are higher than farm supply or online, but the staff can tell you which species are moving through your area and what seed they prefer. Worth a visit if you are new to feeding birds or if you want regionally specific recommendations.

Price ranges and buying options for wild bird food

A 5-pound box of mixed seed at a grocery store costs $7 to $10, or roughly $1.40 to $2.00 per pound. That same money buys a 10-pound bag of black-oil sunflower at a farm store, or feeds your birds for two to three weeks instead of one. Small boxes are convenient, but the per-pound cost is double or triple what you pay for bulk bags.

A 20 to 25-pound bag of black-oil sunflower runs $18 to $25 online or at a farm-supply store, about $0.80 to $1.00 per pound. That bag lasts four to six weeks for a household with two tube feeders restocked every three to four days. A 40-pound bag drops the per-pound cost to $0.70 to $0.90 but only makes sense if you have the storage space and go through more than 10 pounds a month.

Suet cakes are sold individually for $1.00 to $1.50 each or in 10 to 20-packs for $10 to $25. A single cake lasts one to two weeks in a suet cage with moderate woodpecker traffic. No-melt suet costs slightly more (around $1.30 to $1.80 per cake) but works in summer without melting or going rancid.

Nyjer seed is the most expensive at $1.50 to $2.50 per pound even in 10-pound bags, because it is imported and must be heat-treated to prevent sprouting. A 10-pound bag runs $20 to $30 and lasts two to three months in a single nyjer tube feeder with regular goldfinch visits. If goldfinches are rare in your area, the cost is hard to justify.

Mixes with filler grains (milo, red millet, wheat) sell for $0.50 to $0.70 per pound, but half of it ends up on the ground. You are paying less per bag, but feeding fewer desirable birds. A 25-pound bag of straight black-oil sunflower delivers more birds per dollar even at a higher per-pound price.

What not to buy and why it fails

Mixes with milo, red millet, wheat, or oats as the first or second ingredient are sold cheaply, but songbirds throw them out. You will see piles of uneaten seed under the feeder within a day. House sparrows, pigeons, and squirrels eat these grains, but if you are trying to attract chickadees, finches, or cardinals, you are wasting your money. Check the ingredient label before you buy a mix and skip anything with milo in the top three ingredients.

Striped sunflower seed has a thicker shell than black-oil sunflower. Larger birds like jays and cardinals crack it, but smaller songbirds struggle or ignore it. Black-oil sunflower draws a wider range of species and costs about the same per pound. Striped sunflower is common in cheap mixes because it is a lower grade, not because birds prefer it.

Seed bells, cakes, and wreaths are sunflower or millet pressed with gelatin. Birds eat them slowly, and the gelatin gets soft or moldy in rain. They cost two to three times as much per pound as loose seed and work no better. A tube feeder with loose seed is cheaper and easier to keep clean.

Pre-filled feeders sold as ready-to-hang kits are convenient but expensive. The seed inside is often a cheap mix with filler grains. The feeder itself is usually lightweight plastic that cracks after one season. Buy a durable feeder separately and fill it with bulk black-oil sunflower for better results and lower cost.

Flavored suet with artificial colors or added sugar does not attract more birds. Woodpeckers and nuthatches prefer plain suet or suet with insects, nuts, or dried fruit. Brightly colored suet cakes are marketed to people, not birds. Save your money and buy plain rendered suet or a no-melt formula with natural ingredients.

Questions people still ask

I have been feeding backyard birds for over a decade in both suburban and rural settings, and switching from cheap mixes to straight black-oil sunflower doubled the number of species at my feeders while cutting my monthly seed cost by a third.
