The best bird seed for wild birds

Seed is where a beginner's money quietly disappears. The bag looks cheap, the picture on the front shows a cardinal, and a third of what is inside gets flicked onto the lawn within a week. The fix is not spending more. It is reading the panel on the back.

How we ranked these

On published ingredients and guaranteed analysis, both of which are printed on every bag and none of which is a matter of opinion. Fat content matters in cold weather. Ingredient order tells you what you are actually buying. Everything else — the artwork, the species list on the front — is not information.

The panels, side by side

Two things jump out of that table. Nyjer is the lowest-fat item on the list, which is worth knowing before you pay the most per pound for it — you are buying it for finches specifically, not for energy. And mealworms are in a different league on protein, which is why they are a treat food rather than a staple.

Start with black oil sunflower. Really.

Project FeederWatch calls black oil sunflower “the most common type of seed offered at feeders in North America” and “the preferred food item for a wide variety of birds,” naming cardinals, chickadees, finches and sparrows. One ingredient means nothing gets rejected and nothing gets raked up. It is the cheapest way to fill a feeder that birds will empty.

The one real downside is hulls: black oil sunflower leaves a carpet of shells under the feeder, which can kill grass and, left long enough, attracts rodents. If that is a problem where you are, that is what the no-mess bags solve.

When to pay for a no-mess mix

On a patio, a deck or a balcony, hulls are not acceptable and a shell-free mix earns its price. There are two kinds and they are not the same:

• Genuinely filler-free — Lyric Delite is shelled peanuts, sunflower kernels, pecans, pistachios and pumpkin seed. No corn, no millet, nothing birds discard. Expensive per pound; nearly all of it gets eaten.
• Hulled but still padded — Kaytee's Waste Free Blend has no sunflower shells, but cracked corn and millet are in the ingredient list. Nothing gets dropped as a hull, but ground-feeding species will still scatter what they do not want.

The full comparison is in no-mess bird seed.

The specialist seeds, and when they earn a place

Safflower when squirrels have taken over: cardinals, house finches, chickadees and titmice take it and most squirrels leave it. Honest caveat in safflower and squirrels.

Nyjer when you want goldfinches, and only in a narrow-port finch feeder. Detail in nyjer seed.

Suet from October: the highest-energy option and the fastest route to woodpeckers. See suet and suet cakes.

Mealworms for bluebirds, wrens and robins, which largely ignore seed.

Bag size, and the mistake in buying big

Twenty-five pounds is only cheaper if you get through it before it turns. Seed absorbs damp, goes stale and can grow mold, and old nyjer in particular is the single most common reason a finch feeder sits untouched. Buy roughly a month at a time until you know your traffic, and store it properly — how to store bird seed.
