Bird Feeder Guide: Feeder Types, the Best Foods and Where to Hang Them

Bird feeder types and the birds each one draws

Ten feet is the number to start with. That is the gap Project FeederWatch gives between a feeder and the nearest tree or building, because a squirrel can cover anything shorter in a jump, and no squirrel proof bird feeder design outlasts a squirrel that can simply land on it. The feeder itself comes second. A bird feeder delivers one kind of food to one kind of bird, and most feeder trouble is a mismatch: millet in a tube the millet-eaters will not use, sugar water left in the sun for a week.

The feeder types below follow the categories used by the Cornell Lab’s FeederWatch program and the U.S. Fish & Wildlife Service, whose baseline is blunt: if only one feeder goes up, make it a sunflower tube with metal ports or a metal hopper.

Tube feeders

A tube is a hollow cylinder with ports and perches along its length. FeederWatch notes that tubes keep seed fairly dry, and short perches suit small birds such as finches while excluding grackles and jays. Without perches, only clinging birds can feed: finches, chickadees, titmice and woodpeckers. Large-port tubes take sunflower; small-port tubes take nyjer.

Hopper feeders

A hopper is a platform with walls and a roof that hold seed and keep it out of the weather. FeederWatch says large hoppers attract most species, while small hoppers let small birds feed without grackles taking over.

Platform and ground feeding

A platform is any flat, raised surface with food spread on it, and it needs plenty of drainage holes. It is the least selective option. Some birds will not use anything else: FeederWatch points out that many sparrows and doves prefer large flat surfaces and may never visit an elevated feeder. The Fish & Wildlife Service still prefers a raised station to seed tossed on the lawn, because food on the ground picks up damp, mold, bacteria, droppings, fertilizer and pesticide.

Suet feeders

A suet feeder is a wire cage or mesh bag that holds a block of fat, and it is the one feeder of the common types that serves insect-eaters instead of seed-eaters. The Fish & Wildlife Service says the birds that like peanuts (woodpeckers, jays, nuthatches, titmice and chickadees) also take suet. Cages that open only at the bottom are the useful variant, because starlings dislike feeding upside down and woodpeckers do not mind.

Nyjer feeders

Nyjer is a tiny seed that falls straight through ordinary ports, so FeederWatch says it needs a feeder with very small openings. It is best offered alone, not in a mix, to cut waste. It is the classic goldfinch food.

Nectar feeders for hummingbirds and orioles

A hummingbird feeder dispenses sugar water through small holes, and FeederWatch’s one design rule is that it must come apart easily for cleaning. Oriole feeders work the same way with a weaker mix (more on ratios below). Hummingbirds get their protein from insects, so the nectar is only part of what draws them; the Fish & Wildlife Service suggests hanging the feeder near red flowers, and nectar planting is covered in the butterfly garden guide.

Window feeders

A window bird feeder sticks to the glass or hooks onto the frame. Birds can be slow to accept one. The U.S. Fish & Wildlife Service notes that window feeders take longer to be found than hanging or pole feeders and suggests a strip of aluminum foil on the hanger, since the flash of light can catch a passing bird’s eye. Once found, a window bird feeder gives the closest view in the yard.

The best seed for each species

Black-oil sunflower is the best single seed, and every source consulted for this page agrees on it. FeederWatch calls it the preferred food of a wide variety of birds, naming cardinals, chickadees, finches and sparrows; the U.S. Fish & Wildlife Service calls it the hands-down favorite at tube and house feeders. Hulled sunflower leaves no shells on the ground.

For the rest, the match is by species:

Food	Best offered in	Main takers (per FeederWatch and USFWS)
Black-oil sunflower	tube, hopper	cardinals, chickadees, finches, sparrows, nuthatches
Safflower	hopper, platform	cardinals and other big-billed birds; chickadees, mourning doves
Nyjer	small-port tube	American Goldfinch, Pine Siskin, Common Redpoll
White proso millet	platform, ground	juncos, sparrows, doves
Cracked corn	platform, ground	doves, quail, sparrows
Peanuts	mesh cage, platform	jays, chickadees, nuthatches, titmice, woodpeckers
Suet	suet cage	woodpeckers, jays, nuthatches, titmice, chickadees
Mealworms	dish, platform	chickadees, titmice, wrens, nuthatches, bluebirds
Fruit	platform, spike	orioles, mockingbirds, catbirds, robins, waxwings

Cheap mixes are the weak link. The Fish & Wildlife Service describes birds kicking most of a mix out of the feeder to reach the sunflower, and lists corn, milo, oats, wheat, canary seed and colored “berry” pellets as fillers tube-feeder birds do not favor. Separate feeders for separate foods waste less.

Safflower has a second use as a filter. The Fish & Wildlife Service says squirrels and blackbirds tend to leave it alone, and suggests switching to only safflower and nyjer if grackles, starlings, cowbirds or crows are crowding the feeders.

Squirrels, starlings, bears and other guests

Squirrels are the reason the squirrel proof bird feeder exists, and the agencies largely agree on what works. FeederWatch says baffles are usually the best way to keep squirrels off seed. On a pole, the baffle goes below the feeder; the Internet Center for Wildlife Damage Management puts it at least 4 feet off the ground and the feeder itself at least 6 feet up and 10 feet from branches or structures. When squirrels come from above, FeederWatch suggests a tilting baffle at least 18 inches in diameter over the feeder. For a feeder hung on a horizontal line, lengths of plastic tubing threaded over the line spin under a squirrel’s feet. The same climbing-guard principle protects martin poles, as the pole guard notes describe.

Squirrels chew through wood and plastic but not metal and wire, according to the Fish & Wildlife Service, which also warns that most plastic “squirrel-proof” feeders eventually give way despite the claims on the box. Weight-sensitive feeders close the ports when a squirrel’s weight lands on the perch bar, once the tension is set correctly; the ICWDM adds that some squirrels learn to hang from one end and feed anyway. A squirrel proof bird feeder of any kind still needs the 10-foot gap.

Two cheaper tactics have limits. Safflower deters some squirrels, but the ICWDM says some will eat it anyway. Hot pepper works on mammals and does not bother birds’ taste, but the same source warns that powdered cayenne can irritate birds’ eyes and that pepper mixed into suet is the safer form.

Starlings and House Sparrows are not native to North America and are aggressive toward other birds, so the Fish & Wildlife Service recommends choosing feeders and seed that exclude them where possible; a bottom-access suet cage is one example. Cats are worse; feeders belong away from brush piles and low shrubbery that give a cat cover. A hawk is a different matter: if a pile of feathers turns up and no cats live nearby, the Fish & Wildlife Service points out that trapping or poisoning a hawk is against state and federal law.

Bears are the guest that changes the calendar. Bird seed is rich in protein and fat, and the Alaska Department of Fish and Game says feeders should be down between April 1 and November 1. Other states set their own dates.

A placement guide: glass, cover and height

Window strikes are the placement question that matters most, and the reason a window bird feeder or any feeder near glass needs thought. Utah State University Extension cites an estimate of nearly 600 million birds killed by windows in the U.S. each year, with some researchers putting it as high as 988 million. The Ornithological Council’s fact sheet, citing a 2025 estimate, gives 1 billion to more than 3 billion deaths a year across North America.

The usual advice is the 3/30 rule: feeders within 3 feet of a window or more than 30 feet from it, never in between. Utah State University Extension repeats it, and the near half has some support: the Ornithological Council notes that feeders within about 1 meter of a window have been suggested in the research literature as a way to reduce collisions, though strikes still happen if the glass is reflective. The far half is weaker than it sounds. According to the Ornithological Council’s February 2026 fact sheet, the idea that about 10 meters is a safe distance comes from the design of the original study, where 10 meters was simply the furthest point tested. Its conclusion is that no distance from reflective or transparent glass is safe, and that the order of work should be reversed: treat the windows first, then hang the feeder wherever viewing is easiest.

That is the better guide, because a rule of thumb that rests on where a researcher stopped measuring should not decide where a feeder goes.

Treating glass is mostly about spacing. The Ornithological Council calls a pattern 2 inches by 2 inches on center ideal, with 2 by 4 inches also working; FeederWatch says marks should be no more than 2 inches apart; screens on the outside of the glass work too. Turning off lights at night during migration helps, since most birds migrate in the dark. The Council suggests starting with every window that faces the feeder and treating any other window as soon as a strike happens there.

Cover is the other variable. The Fish & Wildlife Service wants feeders near the trees and shrubs birds travel through, but not tucked against brush where cats hide, and Virginia Cooperative Extension makes the same point about clear sight lines with escape cover close by. A feeder far from the door will not get filled in an ice storm, which is exactly when birds need it. Moving the feeder a few feet each season, as the Fish & Wildlife Service suggests, gives the ground underneath time to break down shells and droppings. Nest boxes follow the same yard logic, as the birdhouse guide explains.

Hummingbird feeder nectar, sizes and cleaning

The recipe is short. One part white table sugar to four parts water, which the Smithsonian’s National Zoo, Penn State Extension and FeederWatch all give. Honey, corn syrup and raw sugar are out; the Smithsonian also rules out powdered sugar because it often contains cornstarch, and Penn State Extension warns that fermented honey can cause a fatal fungal disease in hummingbirds.

Two details are contested. Penn State Extension and FeederWatch say to pour boiling water over the sugar, while the Smithsonian says boiling is not needed as long as the sugar fully dissolves. Either way works, as long as the nectar cools before it goes out. Red dye is the other one: FeederWatch calls it harmful, the Smithsonian says it could be harmful, and an older Fish & Wildlife Service booklet said there was no evidence either way but that it was probably unnecessary. Nobody claims it helps, so leave it out. A hummingbird feeder with red ports already does the job.

Size is where people overspend effort. The Fish & Wildlife Service notes that one hummingbird drinks about twice its body weight a day, still less than an ounce, and that early in the season the birds are territorial. A two-ounce hummingbird feeder is enough for one bird; a sixteen-ounce one mostly gives the nectar time to ferment in the sun. Freshness is the real limit. The Ornithological Council says to replace the solution every day in hot weather and every two to three days in cooler weather, and to clean the feeder at least weekly. Extra nectar keeps in the refrigerator for up to a week, according to the Smithsonian.

Bees arrive in hot weather; the Fish & Wildlife Service advises against vegetable oil around the ports, which risks contaminating the nectar. Orioles take a weaker sugar water, one part sugar to six parts water in FeederWatch’s guidance, and FeederWatch also notes that oranges cut in half will often bring them in.

A separate page, hummingbird houses, covers the question of nest boxes for hummingbirds and what to plant and leave in place so they nest nearby.

Cleaning schedule, disease and avian influenza

The most current single document on feeder hygiene is the Ornithological Council’s fact sheet, updated in February 2026 and based on published studies and agency recommendations. It names the diseases linked to seed feeders: salmonellosis, mycoplasmosis, trichomonosis and aspergillosis from moldy seed. It also admits that research on the right cleaning interval is thin. Its recommendation is to clean seed feeders at least once a month, or every two weeks when debris and droppings build up, and nectar feeders weekly. FeederWatch and Virginia Cooperative Extension both suggest about every two weeks. Monthly is the floor, and a busy winter feeder will need more.

The method is specific. Wear gloves, work outside or in a utility sink, never in the kitchen, and skip the dishwasher; the Council notes that home dishwashers vary in whether they actually sanitize. For lightly used feeders, either a soap scrub (1 to 2 teaspoons of dish liquid per gallon of water, about 5 minutes of soaking, then scrubbing) or a bleach soak works. For a dirty feeder, do both: scrub first, then soak 10 minutes in 1 part bleach to 9 parts water, rinse and air dry. Vinegar is untested for this, so the Council says to avoid it. Rake up the hulls and droppings under the feeder about once a month, and never use a leaf blower or vacuum on them, which can put pathogens into the air.

House Finch eye disease is the outbreak most people will actually see. FeederWatch traces it to a strain of Mycoplasma gallisepticum, first noticed in House Finches in the winter of 1993 to 1994 in Virginia and Maryland, with a few cases since in goldfinches, Purple Finches and grosbeaks; sick birds have red, swollen, watery or crusty eyes. When a sick bird shows up, the Ornithological Council suggests taking feeders down for a couple of weeks and cleaning them with both methods before they go back up, while admitting that evidence for this step is mostly lacking.

Avian influenza is the question that brings most people to this topic, and the guidance has held steady. As of October 2026, the USDA’s Animal and Plant Health Inspection Service continues to track detections of highly pathogenic avian influenza in wild birds (its surveillance page was updated October 2, 2026), but that page carries no instruction to remove backyard feeders. The Cornell Wildlife Health Lab states that it is not recommending removal of bird feeders and that passerines do not seem susceptible to the virus or important in spreading it. Cornell’s veterinary college gives the same short answer, “No,” because the disease is very rare in common feeder songbirds, while noting that the outbreak has reached at least 173 species. In 2022 the USDA said removing feeders was not something it specifically recommended unless the household also kept poultry, as quoted by the Wild Bird Feeding Institute. The Ornithological Council’s 2026 fact sheet agrees, with two exceptions: properties with poultry, and yards where wild ducks or geese visit, in which case feeding should stop until no waterfowl have been around for a few days.

Dead birds are a separate step. The Council advises contacting the state wildlife agency or health department, and for large numbers the USDA at 1-866-487-3297. States differ in what they want: the Missouri Department of Conservation asks for reports of dead geese, other waterfowl, raptors and other large birds, and specifically says not to report songbirds. Anyone who must handle one should wear gloves and wash thoroughly afterward.

DIY bird feeder projects the sources describe

The Fish & Wildlife Service is matter-of-fact about building a feeder. Its simplest version is a piece of scrap wood raised a few inches off the ground with a few drainage holes drilled through it, which makes a working platform; birds find it soon enough. A pine cone spread with peanut butter and sprinkled with seed, then hung from a branch, is the classic first DIY bird feeder. A third design uses a wooden dowel or a dead branch with holes carved into it and packed with suet or a peanut butter and cornmeal mixture.

Peanut butter raises the choking question, and the Fish & Wildlife Service answers it: there is no evidence birds choke on it, but since birds have no salivary glands, mixing it with lard, cornmeal or grit makes it easier to eat, and water nearby helps. Like suet, it is a cold-weather food that softens and turns rancid in summer.

The test for any DIY bird feeder is the same as for a bought one. It has to drain, keep seed reasonably dry and come apart or wipe clean, because the Ornithological Council’s first recommendation is a feeder that protects seed from moisture, limits droppings and disassembles for cleaning.

Feeding through the year

Winter is when feeding does the most good. In northern areas the Fish & Wildlife Service suggests starting before cold weather sets in, so birds have time to find the station, and a suet feeder belongs to the cold months.

The fear that feeders make birds helpless is mostly misplaced. Research on Black-capped Chickadees, as summarized by Virginia Cooperative Extension, found that birds with regular feeder access drew only about a fifth of their daily energy from feeders, and that their survival did not differ from birds without feeders. The Fish & Wildlife Service adds that seed feeding can stop once insects are reliable in spring, while fruit and nectar can continue all year.

Spring and the nesting season shift the menu toward protein. FeederWatch notes that mealworms reliably attract bluebirds and are relished by chickadees, titmice, wrens and nuthatches. The Fish & Wildlife Service adds that grit helps birds grind food in winter and spring, and that crushed eggshells add calcium for egg-laying birds in spring. Purple martins are their own case: they take flying insects (the Fish & Wildlife Service notes a preference for dragonflies), so the purple martin section centers on housing, with supplemental feeding in the martin feeding notes.

Fall raises the hummingbird question. The Smithsonian’s National Zoo says it is a myth that late feeders keep hummingbirds from migrating and that keeping clean feeders up past the usual season does no harm, The older Fish & Wildlife Service booklet still advised taking feeders down after Labor Day where winters freeze; the Smithsonian’s position is the more recent one.

Water

Water belongs beside any feeding station. The Fish & Wildlife Service says a source of water can double the number of species in a yard, especially if the water drips, splashes or moves. Penn State Extension’s guidance is specific: birds will only use shallow water, no more than 2 to 3 inches at the deepest; the water should ideally be changed every day, which also stops mosquito larvae; and the basin should be scrubbed weekly. A ground-level bath does best 10 to 15 feet from hiding places so birds can see a cat coming, with shrubs or low branches close enough for a quick escape from hawks. In winter, heated baths or submersible heaters keep water open, and the Fish & Wildlife Service stresses that fresh water matters as much in winter as in any season.

Camera and smart feeders, explained

The technology behind camera feeders is simpler than the marketing. A motion sensor or the camera itself detects movement at the feeder and records a short clip; software then finds the bird in the frame and runs it through an image classifier trained on labeled bird photos, and the result is sent to a phone or saved for later.

A 2025 field study by El Mustapha Mansouri at the Université Libre de Bruxelles, published on arXiv, shows the limits. His system paired a motion-triggered camera on an ordinary feeder with one model that located birds in frames and a second, fine-tuned on 40 Belgian species, that named them. It scored 99.53 percent on held-out test images but about 88 percent top-1 accuracy in the field. Poor winter light reduced performance, the system could not work at night, and males and females of the same species were sometimes confused. That gap between test set and garden is a fair expectation for any camera feeder: strong on clear daylight shots, weaker in dim light and on look-alike plumages.

A camera changes none of the feeding rules: the same seed ports, squirrel gap, cleaning schedule and treated window apply. For the broader picture of attracting birds to a yard, the site index lists the house, feeder and garden pages together.

What stays out of the feeder

Bread is the familiar mistake. The Fish & Wildlife Service lists bread items among the foods to drop when unwanted birds crowd a feeder, and the Ornithological Council’s disease list explains why damp leftovers are a risk: aspergillosis comes from moldy feed. Anything wet, moldy or rancid goes in the trash, and the feeder gets cleaned before it is refilled.

Peanuts are the one item the agencies disagree on. The Fish & Wildlife Service recommends roasted peanuts with no salt and no sugar, and advises against raw peanuts and peanut hearts, while FeederWatch lists peanut hearts as a fine food for small hoppers and platforms. Honey, corn syrup and dyed nectar stay out of the hummingbird feeder. And seed bought for the feeder should be birdseed, not planting stock. The Fish & Wildlife Service warns that a red or pink coating on cracked corn or other seed is a fungicide used on seed meant for planting, one that can kill horses, other mammals and wild birds, and that a bag of it should go straight back to the store.
