The best bird feeders for bluebirds

Bluebirds are the bird people most want and least often get, and the reason is simple enough to state in one line: they do not eat what is in your feeder.

Audubon's account of the Eastern Bluebird's diet is mainly insects and berries — it forages by dropping onto prey from a perch and takes fruit heavily in winter. Nothing in that description involves cracking a sunflower seed. A yard running three seed feeders and a suet cage can be completely invisible to a bluebird sitting on the fence.

So this page is shorter on hardware than most of ours and longer on the two decisions that actually matter: the food, and whether anything else gets to it first.

What a bluebird needs from a feeder

That second row is the whole product category. An open dish of mealworms works perfectly and is emptied within minutes by whichever starling, jay or mockingbird finds it first. An enclosed feeder with a bluebird-sized entry is the only way the expensive food reaches the intended bird.

How we ranked these

On what the listings publish and on whether the design solves the exclusion problem — no testing claim, because we have not run one. The uncomfortable part is that this is a category where sellers publish very little: two of our picks state materials and mounting and essentially nothing else. Where a listing does not give a figure, the product entry says so rather than guessing, and the entry-hole size is the one thing we would measure on arrival. Full criteria here.

We weighed cost heavily here for a specific reason: the odds of success depend on whether bluebirds already live near you, which you cannot know before trying. That makes the cheap feeder a genuinely sensible first purchase rather than a compromise.

The food is the expensive part

Dried mealworms cost more per pound than any seed on this site, and unlike seed almost none of it is wasted, because you are putting out small amounts for one species.

Two practical notes. Dried is the sensible default — live mealworms work better and involve keeping a tub of live insects, which is a commitment most people discover they do not want. And soaking dried worms briefly before putting them out makes them noticeably more attractive, which costs nothing.

Do not put out more than will be eaten in a day. Our mealworm feeder comparison goes into the formats, and the seed-by-bird guide covers where bluebirds sit relative to the birds you already have.

The starling problem, again

Mealworms are the most attractive thing you can put in a yard, and starlings are the most efficient birds at exploiting exactly that. If your enclosed feeder gets raided, the fix is the same one Project FeederWatch recommends for suet: access from underneath only, so the birds that can hang get the food and the ones that cannot, do not.

That is why an upside-down feeder is in our picks on a page about bluebirds. It is not the obvious purchase and it is the one that saves the mealworm budget in a yard with a starling flock. The full bully-bird playbook is here.

Where to put it, which is the opposite of usual

Most of this site tells you to site feeders close to cover — FeederWatch asks for roughly ten feet from trees or shrubs, so a nervous bird has an escape route. Bluebirds want something different.

They hunt over open ground from a perch, so a bluebird feeder works best with open lawn or field around it and a perch nearby to watch from — a fence line, a wire, a bare branch. A feeder tucked into a shrub is well placed for chickadees and wrong for this bird.

The squirrel rules do not change, though. It still wants a baffled pole, and an open site actually makes that easier, because there is nothing to jump from. General placement is here.

Honest odds

This is the part most pages on this subject skip. Whether you get bluebirds is mostly decided before you buy anything.

Audubon puts the Eastern Bluebird in open country with scattered trees: farms and roadsides, forest clearings and open pine woods, and locally in suburbs where there are extensive lawns. If that describes the land around you, a mealworm feeder has a real chance. If you are in dense suburb or woodland, you can run the best bluebird setup available and see nothing, and that is not a failure of the equipment.

Check before you spend: if you have never seen a bluebird within sight of the house, a feeder is unlikely to be the thing that changes it. The cheap feeder plus a small bag of mealworms is the right-sized experiment, and the cedar one is the upgrade you buy once the answer is yes.

What each pick costs you

• The cedar feeder publishes almost no specifications, so the entry hole — the thing the entire design depends on — has to be checked when it arrives.
• The budget feeder publishes even less, and build quality at that price is not comparable to cedar.
• The mealworms are the most expensive food on this site per pound, and they go stale — buy small bags and keep them dry, per the storage rules.
• The upside-down feeder is a suet design being used as a starling workaround; it is not a purpose-built bluebird feeder and some birds take a week to work it out.

The season matters more than with seed birds

A seed feeder is roughly as useful in October as in February. A bluebird feeder is not, and knowing why saves a wasted autumn.

Audubon notes that the Eastern Bluebird eats many berries, especially in winter — the diet shifts from insects toward fruit as the cold arrives. That shift is exactly when a reliable protein source becomes valuable, which is why mealworms tend to get a much better reception in late winter and early spring than in high summer, when insects are everywhere and your dish is competing with an entire meadow.

Two practical consequences. If you are starting in summer and seeing nothing, that is the expected result rather than a failed setup — keep the feeder up and reassess when the weather turns. And late winter, when natural food is thinnest, is the point in the year where a bluebird feeder is most likely to be found for the first time. What else changes in winter is here.

Water does more than you would expect

This is the one addition that changes the odds for this particular bird, and almost nobody mentions it on a page about feeders.

Bluebirds are not seed eaters, which means the single strongest attractant in an ordinary yard — a full seed feeder — does nothing for them. What does work on every bird, regardless of diet, is open water. A shallow bath brings in birds that will never touch a feeder of any kind, and in a freeze it is scarcer than food.

If you have run a mealworm feeder for a season with no result, adding water is a better next move than buying a second feeder. Depth, heating and the cleaning commitment are covered here — and the depth guidance matters, because a deep ornamental basin is as useless to a bluebird as it is to everything else.

What we are deliberately not covering

Nest boxes. They are the other half of attracting this species and they are a genuinely effective one, but this is a bird feeding site and a nest box is a different product with different specifications — entry hole diameters, predator guards, mounting heights and spacing rules that deserve their own treatment rather than a paragraph borrowed from a feeder page.

We mention it because it would be misleading not to: if you have open ground and no bluebirds despite a well-run mealworm feeder, housing is more likely to be the limiting factor than food is. That is worth knowing even though we are not the page that solves it.
