Seasonal
Bird Feeding Calendar
The feeding year has a shape: two traffic peaks, one long lean stretch, and about a dozen jobs that need to happen at roughly the right time. Here is that year month by month, plus instructions for moving it to fit your own climate.
The short answer
- Feeder traffic peaks twice a year: during fall migration, and again in late winter when the natural seed crop has been picked over.
- February and March are the leanest weeks of the year for wild food, not December, which is when most people assume the pressure is worst.
- The single most important calendar entry is not a food at all: it is keeping water available and unfrozen in January and drinkable in July.
- Every date on this page shifts by three to five weeks between the Gulf Coast and southern Canada, so anchor it to your own average last frost date instead of following it literally.
- Cleaning intervals should follow the weather, not the calendar: hot humid weeks need weekly cleaning, dry cold weeks can run monthly.
- Two months carry real deadlines: put nectar feeders out ahead of your local hummingbird arrival, and get seed feeders clean and stocked before the first hard freeze.
A feeding year has a predictable shape. Feeder traffic climbs through fall as migrants pass through and resident flocks form, drops off in late spring when insects take over, and then peaks a second time at the end of winter when the wild seed crop has finally been stripped. Almost every job worth doing at a feeder hangs off one of those turning points.
The calendar below is written for a yard at roughly the latitude of Philadelphia, Kansas City or Denver. That is a deliberate midpoint, and it will be wrong for you by a few weeks in one direction or the other. On the Gulf Coast, spring events run three to five weeks early and fall events run late. In southern Canada and the northern Plains, the reverse is true, and the lean winter stretch is both longer and harder. The regional feeding guides are the fastest way to see how far your area sits from the middle.
Use this as a checklist rather than a script. Read the row for the month you are in, do the one job listed at the end, and ignore what does not apply to your yard. If you only ever act on two entries, make them the January water check and the pre-freeze clean in November.
How to shift this calendar to your own place#
The most useful anchor point in North American bird feeding is your average last spring frost date, which you can get from a local extension service, a seed packet chart or any regional gardening reference. Almost everything that happens in a feeding year tracks it within a couple of weeks, because it tracks the same thing: the return of insects, the leafing out of trees, and the arrival of the birds that eat both.
Work out how far your last frost date sits from mid-April, the midpoint this calendar assumes. If yours is March 1, run every spring entry about six weeks early. If it is May 20, run them about five weeks late. Fall entries move the opposite way against your average first frost.
- Average last spring frost: sets nectar feeder timing, the start of the nesting season, and the point where seed demand drops.
- Average first fall frost: sets the return of heavy feeder traffic and the deadline for a pre-winter deep clean.
- Local hummingbird arrival date: worth looking up separately, because it can run weeks ahead of the frost date on the Gulf and Pacific coasts.
- When your local oaks, conifers and berry shrubs drop their crop: a heavy mast year can suppress feeder traffic until January.
Anchor on frost, not on the month name
Write your own average last and first frost dates at the top of this page in your head, then read every month here as an offset from them. A reader in Houston and a reader in Winnipeg are doing the same jobs in a different order of months.
The feeding year at a glance#
This table is the whole calendar compressed. The detail in the sections below explains why each entry is there.
| Month | What arrives or leaves | Feeder jobs | Watch for |
|---|---|---|---|
| January | Winter flocks settled; irruptive finches may appear | Two fills a day in cold snaps, keep water open, clean monthly | Frozen water, seed frozen into a plug, sick finches |
| February | Same flocks, now hungriest; earliest owl and woodpecker drumming | Keep everything stocked; the wild seed crop is nearly gone | Peak feeder traffic and peak disease risk in crowded flocks |
| March | Blackbirds, robins and early sparrows move through; juncos start to leave | Deep clean everything, put up nest boxes, cut back on suet in the south | Mud, wet seed, and the first flocks of grackles |
| April | Hummingbirds and orioles reach the mid-latitudes; winter sparrows leave | Nectar and jelly feeders out, clean them on a short cycle | Nectar spoiling faster than you expect once days warm up |
| May | Peak songbird migration; nesting begins in earnest | Offer mealworms and calcium, add fruit, stop buying bulk seed | Cowbirds, and seed sitting long enough to spoil |
| June | Residents nesting; feeder traffic at its annual low | Small fills only, clean weekly, keep water clean and shallow | Wet seed, ants at nectar feeders, first begging fledglings |
| July | Fledglings everywhere; hummingbird numbers climbing | Change nectar every two days in heat, shade the feeders, clean weekly | Melting suet, moldy seed, bees and wasps |
| August | Post-breeding wandering; adult songbirds molting and quiet | Buy fresh seed in small amounts, keep cleaning hard | A sudden quiet spell that is molt, not a problem |
| September | Fall migration builds; warblers and thrushes pass through | Rebuild the station, add a second feeder, restart suet in the north | Window strikes as migrants move at night |
| October | Juncos and winter sparrows arrive; hummingbirds leave most of the range | Clean and stow nectar feeders, add a ground tray, stock up on seed | The first heavy squirrel pressure of the year |
| November | Winter flocks form and settle; irruption years show themselves | Full deep clean before the freeze, baffles on, water heater installed | Bears still active in the north and west until true cold |
| December | Flock composition now stable for the winter | Fill late in the day, clear snow off trays, check water daily | Snow burying ground feeders and platform trays |
January and February: the leanest weeks#
Most people assume midwinter is the hard part. It is the second half of winter that squeezes birds hardest, and the reason is simple arithmetic: the fall seed and berry crop has been eaten for four months and no new food arrives until insects hatch. Winter feeding is the broad orientation for this stretch.
January
Put out fat: suet, black oil sunflower, sunflower hearts and peanuts, which are covered in detail in winter high-energy foods. Take down nothing. Clean roughly monthly in dry cold, and more often during a thaw when seed gets wet and refreezes into a plug. Expect stable flocks that arrive at first light and again in the last hour of daylight, plus a hawk working the crowd. During a genuine cold snap, the tactics in extreme cold feeding matter more than anything on the seed list. The one job that matters most: keep water open, because winter water is scarcer in a frozen yard than food is.
February
Put out the same foods and more of them. Take down nothing. Clean on your normal interval and inspect harder than usual, because February crowds are large and close-packed, which is how salmonella spreads. Expect your highest counts of the year, especially in an irruption winter when siskins and redpolls turn up. The one job that matters most: look at the birds, not just the feeder. A puffed, slow, reluctant-to-leave bird in a February crowd is the earliest warning you get.
March and April: turnover and cleanup#
Spring at a feeder is a handover. Winter sparrows and juncos leave over several weeks while the first insect-eaters arrive, and for a while both are present. Spring feeding covers the transition in full, and migration feeding covers what passing birds actually use.
March
Put out the winter menu plus a ground tray of white millet for the sparrow flocks moving through. Take down nothing yet in the north; in the Gulf states, cut back on suet as afternoons warm. Clean everything properly, using the method in how to clean a feeder. This is the natural date for the year's most thorough deep clean. Expect grackles and red-winged blackbirds in noisy numbers. The one job that matters most: get nest boxes cleaned out and hung before the first pairs start prospecting.
April
Put out nectar feeders and orange halves ahead of your local arrival dates, which is the whole subject of when to put out hummingbird feeders. Take down heavy suet if daytime highs are climbing past 80F (27C). Clean nectar feeders on a much shorter cycle than seed feeders. Expect the winter sparrows to thin out and the yard to sound different within a fortnight. The one job that matters most: get the nectar feeder up early rather than late, because an empty hook when the first hummingbird passes costs you the season.
May and June: nesting, and less seed#
Feeder traffic falls off a cliff in late spring, and that is normal. Birds switch to insects because insects are what nestlings need. Nesting season feeding explains what is genuinely useful during this window and what is not.
May
Put out mealworms, fruit and a calcium source, since grit and calcium matter more to a laying female than another scoop of sunflower. Take down anything that is going untouched, because seed sitting in a warm feeder spoils. Clean weekly from here until fall. Expect the biggest species list of the year during peak migration week, and expect it to empty out fast. The one job that matters most: reduce fill volumes so that every feeder empties in two or three days.
June
Put out small quantities of sunflower hearts, which leave no wet hull layer, plus nectar and jelly if orioles use them. Take down surplus feeders and consolidate. Clean weekly, and the birdbath more often. Expect quiet mornings, then noise when fledglings arrive with their parents. The one job that matters most: water. A shallow, clean, refilled bird bath does more in June than any seed.
July and August: heat, mold and molt#
Summer is the season with the highest maintenance load and the lowest visible reward. Everything spoils faster, and the adult birds go quiet while they molt. Summer feeding covers the heat rules in detail.
July
Put out nectar, fruit and a small amount of seed. Take down suet unless you are using a no-melt dough, because rendered fat goes rancid and can foul feathers above roughly 90F (32C). Clean nectar feeders every two days above 85F (29C) and seed feeders weekly. Expect hummingbird numbers to climb steadily and wasps to find the nectar. The one job that matters most: change nectar on schedule, no exceptions, because cloudy nectar is a genuine welfare problem rather than a cosmetic one.
August
Put out the same short menu and buy seed in small bags, since storing bird seed through August humidity is a losing game. Take down anything you are not cleaning weekly. Clean everything, including the ground under the feeders, where moldy seed starts. Expect a strange quiet: adults in heavy molt skulk and skip the feeder. The one job that matters most: rake the spill zone, because a neglected hull layer becomes next month's rodent problem.
September and October: migration at full volume#
Fall is the other traffic peak, and the most rewarding stretch of the year for a species list. Fall feeding covers the buildup; the birds passing through are largely not the birds that will spend the winter with you.
September
Put out sunflower in quantity again, restart suet once nights are reliably cool, and keep nectar going for late hummingbirds. Take down nothing. Clean before you scale up, not after. Expect warblers, thrushes and grosbeaks that will never come back. The one job that matters most: check your windows, because night-migrating birds hit glass the morning after they land. Preventing window strikes is a September priority.
October
Put out a ground tray for the arriving sparrows and juncos, and stock the season's seed while prices and quality are good. Take down and store nectar feeders on your local schedule, which is discussed in when to take down hummingbird feeders; leaving one up does not strand a hummingbird. Clean and dry anything going into storage. Expect squirrel pressure to spike as they cache for winter. The one job that matters most: get baffles fitted before the squirrels learn the route.
November and December: rebuilding for winter#
The point of late fall is that everything should be working before the weather turns, because the jobs are much harder in a frozen yard. If you do one seasonal reset a year, do it in November.
November
Put out the full winter lineup: suet, sunflower, peanuts and a ground tray. Take down nothing, but move feeders if you are going to, because moving a feeder is easier before the flocks settle. Clean everything to a standard you will not have to repeat in January. Expect flock composition for the winter to lock in over about three weeks. The one job that matters most: install the bath heater and test the outlet now, while the ground is workable.
December
Put out fat, and fill late in the afternoon so feeders are full at first light. Take down nothing. Clean monthly in dry cold. Expect the shortest days of the year, which compresses feeding into a narrow window and makes an empty feeder at dawn a real waste of a bird's energy. The one job that matters most: clear snow off trays, perches and ports. If you are worried about going away, feeder dependency puts that in perspective.
The two dates that carry real deadlines
Everything else on this calendar tolerates a few weeks of slack. Two things do not: having a nectar feeder up before the first hummingbird passes through your yard in spring, and having seed feeders clean, stocked and discovered before the first hard freeze in fall. Miss those and you spend the season catching up.
The one job that matters most, month by month#
If you strip the calendar down to a single action per month, this is the list. It is deliberately short enough to remember.
- January: keep the water open.
- February: watch the birds for signs of disease.
- March: clean everything, and get nest boxes up.
- April: hang the nectar feeder early.
- May: cut fill volumes so seed does not sit.
- June: keep the bath clean and shallow.
- July: change nectar every two days in heat.
- August: clear the spill zone under the feeders.
- September: make your windows visible to birds.
- October: fit baffles before squirrels commit.
- November: install and test the water heater.
- December: clear snow off trays after every storm.
The seasons hub collects the longer guides behind each entry, and the cleaning schedule gives intervals in more detail than a calendar row can. If your timing is far from the middle of the continent, read your region's page first, then slide these entries to fit.
Frequently asked questions#
When should I start feeding birds each year?
There is no start date. Birds use feeders in every month, and the useful question is what you put in them. If you want a single moment to build a station from nothing, choose September or October: migrants are moving, resident flocks are forming, and the birds have time to find your feeder before hard weather arrives.
What is the busiest month at a bird feeder?
For most yards it is February or early March, when the natural seed crop has been picked over and nothing new has grown yet. Fall migration produces a bigger species list but a shorter peak. If your local oaks and conifers had a heavy crop, the winter peak can slide later, sometimes into March.
How much does this calendar change between Texas and Canada?
Roughly three to five weeks in each direction, and more for hummingbirds. Gulf Coast spring events run well ahead of the mid-latitude dates used here, and southern Canada runs behind them with a much longer lean stretch. Anchor the calendar to your own average last frost date rather than the month names.
Do I need to feed birds in summer?
No, and many people stop. Summer feeding is optional in a way winter feeding is not, because insects are abundant and adults are feeding nestlings on them. If you do feed in summer, the trade is more cleaning for fewer birds, and water becomes the more valuable offering.
When should I take my feeders down for cleaning?
Any month, but two natural points are March, after the winter crowds break up, and November, before the freeze makes the job unpleasant. Between those, let the weather set the interval: weekly in hot humid conditions, roughly monthly in dry cold, and immediately if you see a sick bird.
Does leaving feeders up delay migration?
No. Migration in North American feeder birds is driven mainly by day length and internal timing, not by food availability in one yard. A stocked feeder in October helps late individuals refuel rather than persuading healthy birds to stay. This comes up most often with hummingbirds, and the evidence there is the same.
