Backyard bird feeding, worked out properly
Which feeder, which seed, hung where, cleaned how often, and what to do when a squirrel beats all of it. Every answer here is built from published research and agency guidance, then worked through to the number or the decision you actually need.

The one thing most bird feeding advice gets wrong#
Almost every "best bird feeder" article ranks products. That is the wrong unit. A feeder only works as part of a set: a design, a food, a position, and a cleaning interval. Change any one of them and the birds change. A tube of black oil sunflower on a baffled pole in the open produces a completely different yard from the same tube filled with a supermarket mix and hung off a fence post, and the feeder is not the variable that mattered.
So this site is organized the way the decision actually works. Pick the birds you want, and the food follows. Pick the food, and the feeder follows. Pick the position, and your squirrel problem is either solved or permanent before you have bought anything.
Which birds are even possible depends on where you live, so if you are starting from scratch, feeder birds by region is the fastest way to find out what your yard can realistically produce.

Bird Feeder TypesHow feeder designs divide the bird community into perching, clinging, ground, nectar and fruit feeders, what each design is for, and which three cover a yard.Bird Food and SeedEvery food a backyard feeder can offer, sorted into seven groups, with the two questions that decide which ones belong in your yard and which are wasted money.Backyard Feeder BirdsWork out which feeder birds your yard can get, using range, habitat, season and food, then feed the five guilds that make up almost every North American feeder list.Squirrels, Pests and Problems at Bird FeedersWork backwards from what you can see: an emptied feeder, shells with no birds, untouched seed, a yard that went silent. Each symptom has a short list of causes.Feeder Placement, Safety and MaintenanceThe four variables that decide whether a feeding station works: where it stands, whether it is safe, how often it is cleaned, and what holds it up.Feeding Birds Through the YearWhat really changes between January and July at a feeder: wild food supply, energy demand, molt, migration and breeding, and why the summer lull is not a problem.Head-to-Head ComparisonsTwelve bird feeding decisions people get stuck on, each settled with a verdict and the condition that flips it: feeders, seed, nectar and squirrel defense.Bird Feeding Calculators and ToolsSix free calculators for backyard bird feeding: nectar ratios, seed cost per pound eaten, feeder selection, baffle geometry, cleaning intervals and food matching.Data and Original AnalysisOur reference tables for backyard bird feeding: the species-by-food preference matrix, cost per pound eaten, energy density, and every feeder design scored.Reference DeskThe support layer of the site: a glossary of feeding terms, the questions that cut across every guide, where our numbers come from, and the myths worth retiring.
The preference matrix#
Most feeder advice repeats the same soft claims: "cardinals like sunflower", "finches like nyjer". Useful up to a point, useless when you are standing in front of six bags of seed. So we scored every common feeder food against every common feeder bird on one five-point scale, from top-tier favorite down to not-a-feeder-food, and published the whole grid.

That is eight of the thirty-four species in the full food preference chart. Read a row to see what one species wants. Read a column to see who a bag of seed actually buys you. Feed the matrix into the bird food matcher and it will tell you the smallest set of foods that covers the exact birds on your list.

What a bag of seed really costs#
Shelf price is not the price. Black oil sunflower is roughly a quarter hull by weight, so a $1.35 per pound bag delivers food at about $1.80 per pound eaten. Cracked corn is the cheapest thing in the shed per pound and the leanest, which makes it a ground-tray food rather than a substitute for sunflower or suet in cold weather. The full working, seed by seed, is in cost per calorie.
| Food | Edible fraction | kcal / 100 g edible | Fat | Price / lb | Cost / lb eaten | kcal per dollar |
|---|---|---|---|---|---|---|
| Black oil | 75% | 584 | 51% | $1.35 | $1.80 | 1,472 |
| Hearts | 100% | 584 | 51% | $2.60 | $2.60 | 1,019 |
| Safflower | 65% | 517 | 38% | $1.95 | $3.00 | 782 |
| Nyjer | 86% | 515 | 35% | $3.40 | $3.95 | 591 |
| Millet | 82% | 378 | 4% | $1.10 | $1.34 | 1,278 |
| Cracked corn | 100% | 365 | 4% | $0.75 | $0.75 | 2,208 |
| Suet | 100% | 740 | 75% | $2.20 | $2.20 | 1,526 |

How this site is put together#
We publish the reasoning, not just the conclusion. Every number that is our own model rather than a published measurement is labeled as such, and the assumptions behind it are written down in our methodology. Where the evidence is genuinely thin, the page says so instead of picking a side.
We do not sell feeders, seed or anything else, we take no product samples, and no page here recommends a brand. That is a deliberate constraint: it means the answer to "which feeder" can be "none of them, move the pole" when that is the truth.
