What to Feed Birds in Winter: Best Foods & What to Avoid

The winter menu at a glance

Food (and feeder)	Who eats it in winter	Why it matters now
Black-oil sunflower tube, hopper, or platform	Cardinals, chickadees, titmice, nuthatches, finches, jays, woodpeckers	High in oil, thin shell — the most calories for the least effort
Suet suet cage or tail-prop feeder	Woodpeckers, nuthatches, chickadees, titmice, Carolina Wrens	Nearly pure fat; stands in for the insects winter takes away
Peanuts (plain, unsalted) mesh peanut feeder or platform	Blue Jays, woodpeckers, nuthatches, titmice, chickadees	Fat and protein together
Sunflower hearts tube or hopper under a weather dome	Goldfinches and every sunflower eater	No shells to crack, no hulls on the snow
Nyjer (thistle) thistle tube or nyjer sock	Goldfinches, plus Pine Siskins and redpolls in some winters	Tiny, oily seed small finches can manage
White proso millet low platform or cleared ground	Juncos, White-throated and Song Sparrows, Mourning Doves	The favorite of birds that feed on the ground
Safflower hopper or platform	Cardinals, titmice, chickadees, doves	Rich in fat, and squirrels and starlings usually leave it alone

If you only buy one thing, buy black-oil sunflower. If you buy two, add suet. Those two cover nearly every bird that winters in a Northeast backyard. For the year-round version of this chart, see our bird food guide.

Why fat matters most in winter

Gram for gram, fat carries more than twice the calories of carbohydrate or protein. For a bird that weighs less than half an ounce, that difference is everything.

Small birds spend a winter day eating almost nonstop, storing a thin layer of fat that they burn overnight to stay warm. Black-capped Chickadees go a step further: on cold nights they let their body temperature drop by roughly 10 to 20°F to save energy — a controlled hypothermia — and warm back up at dawn. That's why the first hour of daylight is the busiest at any winter feeder. The birds are refueling after a long night.

High-fat foods let birds replace those reserves quickly. Low-fat fillers — and bread — take up room in a small stomach without delivering the energy a cold night demands.

Suet: the cold-weather powerhouse

Suet is beef fat, usually sold as rendered cakes that slide into a wire cage. It's one of the best winter foods you can offer, because the birds that love it most — woodpeckers, nuthatches, chickadees, titmice, and Carolina Wrens — normally live on insects, and winter takes those away.

A few practical notes:

Winter is suet season. Cold weather keeps it firm and fresh. In warm weather it can go rancid or soften, so many people take it down in summer or switch to "no-melt" cakes.
Plain cakes are fine. Woodpeckers don't need fancy flavors. Cakes with seeds, nuts, or dried fruit mixed in simply draw a wider crowd. Or make your own with our no-melt suet recipe.
A tail-prop feeder helps bigger woodpeckers. Red-bellied Woodpeckers and flickers like to brace with their tails, the way they do on a tree trunk.
Skip bacon grease and meat drippings. They're often heavy in salt and preservatives, so plain rendered suet is the safer choice.

Don't forget water

This is the thing most people overlook. Most birds drink every day, in every season, and they bathe to keep their feathers clean. Clean, well-kept feathers are what hold a bird's insulating layer of warm air. In a Northeast January, though, open water is hard to find. Birds can eat snow, but melting it costs body heat they can't easily spare.

A heated birdbath, or a small heater made for an existing bath, keeps water open on the coldest days. Some practical rules:

Keep it shallow — an inch or two deep is plenty.
Add a few stones that poke above the surface, so birds can drink without getting soaked. Cornell's FeederWatch team calls this especially important in winter.
Never add antifreeze, glycerin, or salt to keep water from freezing. They can harm birds and mat their feathers. Use a heater made for birdbaths, plugged into a ground-fault (GFCI) outlet.
Place it near cover, like your feeders, so birds have a quick escape.
Keep it clean. Rinse and refill every few days.

In many yards, open water in a hard freeze draws birds that never touch the feeder.

What not to feed birds in winter

The kindest instinct — sharing kitchen scraps — can do more harm than good. Leave these out:

Bread, crackers, and baked goods. They fill birds up without real nutrition, leaving less room for the fat they need.
Salted or seasoned foods. Salted nuts, chips, and seasoned leftovers. Buy plain, unsalted peanuts sold for birds.
Bacon grease and meat drippings. Salt and preservatives; offer rendered suet instead.
Milk. Birds can't digest it.
Moldy, wet, or clumped seed. Mold can make birds sick. Toss it, dry the feeder, and refill with fresh seed.
Cheap filler mixes. Bags heavy with red milo, wheat, and oats are mostly kicked to the ground, where they rot under the snow.

When to start feeding in fall — and the bear rule

October and November are the perfect time to start. Dark-eyed Juncos and White-throated Sparrows arrive from the north with the first cold nights, and resident birds are settling into the routes they'll follow all winter. A feeder that's up by Thanksgiving is part of the map.

The exception is bear country — and black bears now live across most of the Northeast, from northern New Jersey and Connecticut up through Maine. They stay active into late fall and are drawn to bird feeders. Vermont Fish & Wildlife, for example, recommends waiting until December 1 to put feeders up and taking them down by April 1; in southern New England, agencies ask for feeders to come down by mid-March. If bears live near you, check your own state wildlife agency's advice before you hang the first feeder.

Seven habits that help most in winter

Fill up before a storm. Birds feed heavily ahead of snow. A full feeder the afternoon before a storm helps them through it.
Clear the snow afterward. Brush off platforms and feeder roofs, and sweep a patch of ground for juncos, sparrows, and doves.
Mind the rush hours. Make sure food is out at first light, after the long night, and again in the last hour or two before dusk.
Be steady through the worst weather. Birds don't depend on any one feeder, but in a severe cold snap a full feeder is a real help. If you're away for a stretch, ask a neighbor to top it up.
Add shelter. A brush pile, or your old Christmas tree propped up near the feeders, gives birds a windbreak and a hiding place from hawks.
Leave nest boxes up. Chickadees, titmice, and bluebirds sometimes roost in them on cold nights.
Keep feeders clean and the seed dry. Winter crowds help diseases spread. Wash feeders about every two weeks, and use a weather dome or tray so seed doesn't sit wet.

The bottom line

In a Northeast winter, feed fat: black-oil sunflower and suet first, then peanuts, sunflower hearts, nyjer, and millet for the ground feeders. Add open water, keep the food steady through storms, and skip the bread and salty scraps. Your feeder becomes a reliable stop for the birds riding out the cold just outside your window.

Common questions

What is the best food to feed birds in winter?

High-fat food. Black-oil sunflower seed and suet are the top two, followed by plain peanuts, sunflower hearts, nyjer for finches, and white proso millet for ground-feeding birds like juncos and sparrows.

Do birds become dependent on feeders in winter?

No. A Wisconsin study of Black-capped Chickadees found that birds with feeders nearby got only about 21% of their daily energy from them — the rest still came from wild food. Feeders are a help rather than a lifeline, but in severe cold that help counts: in a companion study, chickadees with feeder access survived harsh winters at a markedly higher rate.

Should I put out water for birds when it's freezing?

Yes, if you can keep it open. Birds need water all winter to drink and to keep their feathers clean for insulation. Use a heated birdbath or a birdbath heater, keep it shallow, and never add antifreeze, glycerin, or salt.

Is it OK to feed birds bread in winter?

It's best not to. Bread fills birds up without the fat and nutrients they need to survive cold nights. Black-oil sunflower seed or suet does far more good for about the same cost.

When should I start feeding birds in the fall?

October or November is ideal — winter visitors like juncos arrive with the first cold nights. In bear country, wait for your state's go-ahead: Vermont, for example, recommends putting feeders up on December 1.
