Best Finch Bird Seed: 5 Nyjer Seeds and Finch Blends Compared

The best finch bird seed for most backyards is straight nyjer, the tiny black seed often sold as thistle, poured into a feeder with very small ports or a mesh sock and offered on its own. Project FeederWatch’s guide to food types says nyjer attracts finches including American Goldfinch, Pine Siskin, and Common Redpoll, and that it is best fed by itself rather than in a mix to prevent waste. Our Best Overall is Wagner’s Nyjer Seed in a 10 lb bag. Per Wagner’s, it packs 150,000 seeds per pound, and Wagner’s sells the same seed in 2, 5, 10, and 20 lb bags. We compare five finch seeds in all: three bags of straight nyjer and two finch blends.

We compared the five on ingredients, the fat guarantee where the maker prints one, bag size, the sizes each maker sells, and the feeders each listing names. Two published sources set the criteria. FeederWatch’s food guide covers what nyjer is and how to feed it. Audubon’s list of top foods for winter bird feeding says nyjer is eagerly eaten by the small finches, naming goldfinches, House, Purple, and Cassin’s Finches, Pine Siskins, and redpolls, and that it has to go in a thistle feeder: a tube with small, seed-sized holes or a thistle sock.

This guide covers choosing seed for backyard feeders. It is not advice on caring for sick or injured birds; if you find one, contact a licensed wildlife rehabilitator or your state wildlife agency.

Our Top Finch Seed Picks

• Best Overall: Wagner’s Nyjer Seed. Straight nyjer with 150,000 seeds per pound, which Wagner’s calls extra clean and sells in four bag sizes; this listing is the 10 lb bag, for yards with several finch feeders.
• Best High-Fat Finch Blend: Kaytee No Mess Finch Seed and Nyjer Blend. Nyjer and hulled sunflower chips with a guaranteed minimum of 44.0% crude fat, per Kaytee, the highest fat figure any maker prints for a product in this guide.

Three picks carry no title. Lyric Nyjer Seed and Kaytee Nyjer Seed are both straight nyjer like our Best Overall, in smaller 3 lb bags. Kaytee prints a guaranteed analysis for its nyjer (at least 35.0% crude fat). Lyric’s listing says its seed is sterilized so it will not sprout, but FeederWatch says imported nyjer is heat-treated anyway. Neither point earns a title. Kaytee Wild Finch Blend is a multi-seed mix led by millet. It is on the list because its listing names finches and Kaytee includes nyjer, but Nebraska Extension advises against finch mixes built this way, as explained below.

Finch Seed Compared

Ingredients, fat, and the other sizes on offer come from each maker’s page, linked in the first column. Bag size is the size on the Amazon listing. Feeders are those named on the listing or the maker’s page; two products name none.

How We Chose

We searched Amazon US for nyjer seed, thistle seed for finches, and finch bird seed, and considered products from the bird food brands on our reviewed list. Each product had to be sold new, average at least 4.0 out of 5 from at least 30 owner ratings, and name nyjer, niger, thistle, or finches in its own listing. We then read every listing in full and cut what did not belong. The same Wagner’s nyjer is also listed on Amazon in 5 lb and 50 lb bags; we kept one listing so you see five different products. Two Kaytee blends named finches among many other birds but are a general songbird mix and a balcony blend whose listings do not mention nyjer, so they were dropped. A canary and finch food sold for pet birds was left out, and so was a Kaytee nyjer listing that sells the seed already packed in two mesh socks, since the plain bag of the same seed is here. We took no more than three products from one brand, which is why two more Kaytee finch blends did not make the list.

For Best Overall we require a product from a brand we have vetted, with at least 1,000 owner ratings and an average of at least 4.2 out of 5, that fits the keyword best and that its maker still lists. All three straight nyjer bags meet that bar, and straight nyjer is the form FeederWatch recommends. Wagner’s takes the title: it is the one bag here whose maker gives a seed count per pound (150,000), Wagner’s calls the seed extra clean, and its own page still lists it in four bag sizes, from 2 to 20 lb, so you can match the bag to how fast your finches eat. The 10 lb bag on this listing suits a yard with several finch feeders; with one feeder, a smaller size makes more sense. The other four follow our research order, straight nyjer first and blends after. The FeederBirdLab Score on each card is a separate measure and does not set the order or the Best Overall, as explained in how we calculate the score.

We matched each Kaytee listing to Kaytee’s product page by UPC, and found the same product names, ingredients, and sizes on the Wagner’s and Lyric pages. None of the five listings conflicts with its maker on ingredients or bag size, so no FeederBirdLab Score was adjusted. Our full method is on the How We Review page.

How to Choose the Best Finch Bird Seed

All five bags here feed finches, but they are built differently: three are a single seed, one is a two-seed blend, and one is a mix of seven ingredients. These are the checks that separate them.

Match the seed to the feeder you already own

A bag sold as thistle bird seed, niger, or nyjer holds the same seed, and FeederWatch’s food guide, which covers the common types of bird seed, says nyjer is so small it requires a special feeder with very small feeding ports. The question here is which bag suits the finch feeder you have: Wagner’s says its nyjer is for finch feeders with smaller holes and tiny perches, Lyric’s listing names nyjer tube or sock feeders, Kaytee says its nyjer can be used in a tube or sock feeder, and the No Mess blend’s listing names no feeder at all.

Decide whether a blend earns its place

Makers and sources disagree here. Kaytee says its No Mess Finch Blend of nyjer and sunflower chips is more enticing than straight nyjer alone. FeederWatch says nyjer is best fed by itself to prevent waste. Nebraska Extension’s bird feeding guide sits between the two: it says a good finch mix contains only fine sunflower chips and nyjer seed, and it warns against commercial finch mixes with millet, canary grass seed, and other fillers that finches reject and scatter on the ground. Our default follows the more cautious advice. Buy straight nyjer for a finch feeder; if you want a blend, pick one that is only nyjer and sunflower chips, like the Kaytee No Mess blend, and check that your feeder’s ports pass the chips without letting the nyjer run out.

That leaves the Kaytee Wild Finch Blend as the odd one out. Per Kaytee, millet is its first ingredient, followed by niger, canary grass seed, hulled sunflower, and flax, which is the kind of mix Nebraska Extension tells finch feeders to avoid. FeederWatch says millet is a favored food of many smaller ground-foraging birds and that a handful on the ground keeps juncos and sparrows happy. So the Wild Finch Blend makes sense where you want finches above and juncos and sparrows below. If your goal is a feeder that finches empty and nothing else touches, it is the wrong bag.

Read the fat guarantee where there is one

Only Kaytee’s product pages print a guaranteed analysis for the products here, and the three figures are far apart. The No Mess Finch Blend guarantees at least 44.0% crude fat and 23.0% crude protein, the straight Kaytee nyjer at least 35.0% fat and 18.0% protein, and the Wild Finch Blend at least 13% fat and 11% protein. Wagner’s describes its nyjer as having high fat and protein content but gives no number, and Lyric’s page gives none. Treat these as minimums from the label, not measured averages, and use them to compare bags, not to judge how well a bird is fed.

Buy a bag your finches will finish while it is fresh

Nebraska Extension explains why bag size matters with nyjer. The seed is imported and heat-sterilized to avoid introducing non-native plants, the sterilization shortens its shelf life, and finches will reject old nyjer. The guide’s advice is simply to make sure the seed is fresh. In practice, that means buying the size you will use up, and every maker here sells more than one. Wagner’s sells its nyjer from 2 to 20 lb, Lyric in 3 and 10 lb, and Kaytee from 3 to 20 lb; only the No Mess blend comes in a single 8 lb size. If you run one tube for a handful of goldfinches, a 3 lb bag of the Lyric or Kaytee nyjer is the safer start. If you have a crowd of siskins emptying two socks a week, the 10 lb Wagner’s bag makes sense.

Storage helps too. Kaytee’s pages tell you to reseal the package and keep it in a cool, dry place, preferably in a sealed container, to protect against insects, and to discard old food before refilling a feeder. The Wagner’s listing says its bag closes with a velcro press-lok, which keeps the bag shut between fills, but Kaytee’s advice to use a sealed container applies to any bag.

Check the first bag for debris

Nyjer goes through very small ports, so in our view twigs, stems, and dust in the bag deserve a look before you fill. Wagner’s calls its nyjer extra clean, and the Lyric listing says its seed is carefully selected and cleaned. Lyric owners mostly agree: one says the seed seems really clean, with no other seeds, no stems, and no dust they noticed. Another titles their review “Good but inconsistent”: one bag had virtually no junk, but the latest order has “junk in the seeds that I have to pick out, piece by piece.” The same owner mentions a past problem with debris in seed clogging the bottom holes of a feeder. When a new bag arrives, pour a scoop onto a plate and pick out anything that is not seed before you fill the feeder.

Who Should Look Elsewhere

If you want one bag for every bird in the yard, nyjer is the wrong place to start. The sources here tie it mainly to finches, so a general wild bird mix is the better fit for a single hopper. Nyjer is a second feeder for finches, not a replacement for your main one. If you do not have a small-port tube or a mesh sock yet, buy the feeder first; nyjer in a sunflower tube is the spillage FeederWatch warns about.

Among the picks, skip the 10 lb Wagner’s bag if only a few finches visit and the seed would sit for weeks. Skip the Kaytee Wild Finch Blend if you want a finch-only feeder, since millet leads its ingredient list. Skip the Kaytee No Mess blend if you only have a fine nyjer sock or a nyjer tube and do not want to experiment: the listing names no feeder type, so you would have to see whether the sunflower chips pass your feeder’s openings.

Finch Bird Seed FAQ

Is straight nyjer or a finch blend better?

Start with straight nyjer. FeederWatch recommends feeding it by itself to prevent waste, and every straight bag here fits a standard nyjer tube or sock. A blend of nyjer and sunflower chips, such as the Kaytee No Mess Finch Blend, is the reasonable second choice if your feeder’s ports pass the chips. Avoid finch mixes heavy in millet and canary grass seed if finches are the only birds you want, as Nebraska Extension advises.

Will the sunflower chips in the No Mess blend fit my nyjer feeder?

Maybe. The Amazon listing names no feeder type, and neither the listing nor Kaytee’s page gives a size for the hulled sunflower chips, so check before you fill. Pour a little into the feeder over a plate and see whether the chips come through the ports or mesh. If they stay stuck inside, keep that feeder for straight nyjer.

Is nyjer seed high in fat?

Kaytee’s pages give minimums: at least 35.0% crude fat for its straight nyjer, 44.0% for the No Mess blend of nyjer and sunflower chips, and 13% for the millet-led Wild Finch Blend. Wagner’s describes its nyjer as high in fat and protein without giving a figure, and Lyric’s page lists none. A guaranteed minimum tells you the least the bag holds, not the exact amount.

Why won’t finches eat my nyjer seed?

Old seed is the first thing to check. Nebraska Extension says heat sterilization gives nyjer a short shelf life and that finches reject old nyjer. Kaytee’s feeding instructions say to discard old food before refilling and to clean feeders regularly to keep down mold and bacteria. Empty the feeder, refill it with seed from a fresh bag, and buy a smaller size next time if the last one sat open for months. Fresh seed will not help if no finches are nearby: FeederWatch says nyjer has become popular largely because of its ability to attract finches.

Final Thoughts

Buy straight nyjer for a feeder built for it, in a bag your finches will finish while it is fresh. Our picks by need:

• Best Overall: Wagner’s Nyjer Seed. Straight nyjer, 150,000 seeds per pound and sold in four bag sizes, per Wagner’s.
• Best High-Fat Finch Blend: Kaytee No Mess Finch Seed and Nyjer Blend. Nyjer and sunflower chips, at least 44.0% crude fat, per Kaytee.

If you want a smaller bag of straight nyjer, the 3 lb Lyric and Kaytee bags are straight nyjer in a size one feeder can finish. For more seed, suet, and feeding supplies, browse our Bird Food section.
