When to Take Down Hummingbird Feeders in Fall

When to stop feeding hummingbirds comes down to one rule: keep the feeder up until about two weeks after the last hummingbird visits it, then clean it and put it away. In the northern states that usually lands in late September or October. Across the middle of the country it is late October, and along the Gulf Coast it runs into November. In parts of the South, the Southwest, and the West Coast, a clean feeder can stay up all winter. Taking it down early does not help the birds leave, because feeders do not stop hummingbirds from migrating.

Below is the rule with its sources, fall dates by region and by state from wildlife agencies and university extension services, what to do about the late birds that show up after “your” hummingbirds are gone, and how to put the feeder away for the winter.

This guide covers fall timing for backyard hummingbird feeders. It is not advice on caring for sick or injured birds; if you find a hummingbird that cannot fly or is grounded in cold weather, contact a licensed wildlife rehabilitator or your state wildlife agency.

When to Stop Feeding Hummingbirds: The Two-Week Rule

The clearest fall rule we found comes from the National Audubon Society’s guide to a hummingbird-friendly yard: in the fall, keep your feeders up for two weeks after you see the last bird using it. Alabama Extension gives the same advice in its fall migration article: even after most hummingbirds have come through, leave the feeders out for another couple of weeks to accommodate late migrants.

Other sources put it more loosely, and none of them pushes for an early end date. Audubon’s hummingbird feeding FAQ says you can leave feeders out as long as you have hummingbirds around, and even after they disappear, because late migrants or out-of-range species can show up into early winter. Smithsonian’s National Zoo gives approximate end dates by region (below) and adds that keeping clean feeders up longer than its guidelines suggest does no harm and can help any stragglers.

In practice, the rule works like this:

• Note the date of the last visit. Write it on a calendar. A feeder you can see from the kitchen window makes this easy; one at the back of the yard may need a few minutes of watching each morning and late afternoon.
• Count two weeks from that day. If a bird shows up in the meantime, start counting again. As Purdue Extension points out, fall visitors can be migrants passing through after your summer birds have left.
• Keep the nectar fresh while you wait. Audubon says to follow the cleaning guidelines even if the nectar goes untouched. The National Zoo’s minimum in cooler spring and fall weather is a weekly cleaning and refill, and warm spells call for changing the nectar more often. With few visitors, fill the feeder only partway so less goes to waste.
• Do not use a fixed date as a reason to stop early. If the calendar says October 1 but a hummingbird visited yesterday, the two-week count wins.

Fall nectar is the same plain sugar water as in summer: the National Zoo recipe is one part refined white sugar to four parts water, with no red dye.

When to Take Down Hummingbird Feeders by Region and State

The National Zoo’s approximate fall end dates are the best national starting point:

• Gulf Coast and other southern parts of the U.S.: feeders up through early November.
• Middle latitudes: through late October.
• Farther north: through late September.
• Areas where hummingbirds occur all year: no need to take feeders down.

State sources are more specific. Each row below comes from a state wildlife agency or a state university extension service, and each one links to the page we read. Where a source gives a migration window but no feeder date, the feeder column says “Not given”; add two weeks to the end of the window. States without an official fall page are left out rather than filled in with a guess.

Two rows need context. Penn State’s advice, to leave feeders out until September when the birds leave the state, gives the earliest end point we found. The National Zoo’s window for the North runs through late September, and the two-week rule from Audubon and Alabama Extension can push later still. We would follow the later date: the Zoo says a clean feeder left up longer does no harm. The Kentucky publication is more than two decades old, but its advice matches the newer pages.

Mass Audubon is the one source we read that sets a cold-weather cutoff. It says a bird that fails to migrate, because of injury, illness, or what it calls genetic miswiring, may be seen at feeders off season only because the food is there, that leaving feeders up in really cold weather can injure a hummingbird’s bill (rare, but possible), and that it is best to take feeders down before freezing nights become common. National Audubon’s FAQ covers the same situation from the other side, with advice for feeding a bird that stays past migration (see below). Our reading: if no hummingbird has visited for two weeks and hard freezes have started, take the feeder down. If one is still visiting, keep the feeder up only if you can keep the nectar from freezing.

Will Leaving a Feeder Up Stop Hummingbirds From Migrating?

No. This is the most common reason people take feeders down early, and every official source we read that addresses it says the same thing:

• Audubon’s FAQ says hummingbirds are genetically programmed to head south in the fall, and that it is not a lack of nectar or colder weather that makes them leave; they know it is time from changes in the length of the day and the angle of the sun.
• The National Zoo calls it a myth that leaving feeders up too late in the fall will keep the birds from migrating, and says hummingbirds have an internal clock regulated by changing day length.
• Penn State Extension says the concern that feeders hold hummingbirds in northern areas has proved to be unfounded.
• Georgia DNR says you cannot keep hummingbirds from migrating by leaving feeders up in fall and winter, because they migrate in response to a decline in day length, not food availability.
• The Minnesota DNR, Missouri Extension, and Purdue Extension say the same: hummingbirds migrate when it is time to go, and a feeder will not stop or delay them.

What a fall feeder does is help the birds that are already on the move. Purdue Extension says feeders are important in fall for helping hummingbirds gain weight for migration, and that before migrating they “balloon” from their normal 0.1 to 0.12 ounces to 0.19 to 0.22 ounces. The Ohio State column puts it plainly: hummingbirds that find good supplies of nectar or feeders have an easier time on the journey.

An older Alabama Extension page, Hummingbirds in Alabama, describes a pattern that often makes people think the season is over: in late summer or early fall, just before migration, a lot of hummingbirds may use the feeders and then disappear overnight. A busy feeder that goes quiet in a day usually means the birds have left on schedule, not that something drove them off. That quiet day is when the two-week count starts.

Late Migrants and Winter Visitors

The two weeks after the last regular visit are not wasted time. In the East, the hummingbirds that turn up late in fall are often not Ruby-throated Hummingbirds. Several sources describe western species showing up east of their usual range:

• Purdue Extension says Rufous Hummingbirds can be seen at feeders in Indiana during late autumn, and that leaving a feeder up later might attract another species.
• Missouri Extension says the Rufous Hummingbird and a few other western species are casual migrants in the western half of the state in late summer and fall. The Oklahoma Department of Wildlife Conservation calls the Rufous an occasional fall migrant throughout Oklahoma.
• Georgia DNR lists the Rufous as Georgia’s most common wintering hummingbird and says wintering hummingbirds can begin arriving as early as August and appear at feeders any time through fall and winter.
• Project FeederWatch says the hummingbirds seen in Gulf Coast states and the Southeast in winter are likely Rufous Hummingbirds, and that vagrants are increasingly reported across the Southeast. It also describes participants in Georgia and in Columbus, Ohio, whose Rufous visitors were tagged by licensed banders.

In the warmest parts of the country, fall never really ends the season. Georgia DNR asks people to keep at least one feeder up all year, and Mississippi State Extension says coastal residents can keep feeders up into late fall and early winter.

If a Hummingbird Is Still Visiting When Nights Turn Cold

Audubon’s FAQ addresses this case directly. If nighttime temperatures regularly drop below freezing where you live, you need to keep the nectar from freezing. Where nights dip only slightly below freezing, the nectar may not freeze, because a sugar solution has a lower freezing point than plain water. Audubon also says that, contrary to popular belief, drinking cold nectar does not appear to “cold stun” the birds.

That leaves two options for a late bird in a cold region: keep a feeder going with nectar that stays liquid, which some people do with a heated feeder, or follow Mass Audubon’s advice and take feeders down before freezing nights become common. If you keep feeding, keep cleaning: Audubon’s cleaning guidelines do not pause in cold weather.

Mass Audubon notes that hummingbirds can enter torpor, a state in which their metabolism slows down sharply, to get through hard conditions, and that a bird in torpor is almost impossible to wake. If a hummingbird is on the ground, cannot fly, or stays motionless, contact a licensed wildlife rehabilitator or your state wildlife agency rather than handling it yourself.

Report Hummingbirds You See in Late Fall and Winter

A late hummingbird is useful data. Georgia DNR asks anyone who sees a hummingbird at a feeder from October to the end of February to contact its Wildlife Conservation Section, and says those reports help document wintering hummingbirds and their habitat needs. It also warns that wintering hummingbirds are hard to identify, so do not assume the bird at your feeder is a Rufous. FeederWatch makes the same point and says banders help confirm the species.

Outside Georgia, two community science programs take reports:

• Project FeederWatch is a November to April survey of birds that visit backyards and other sites in North America; its season starts November 1, and participants can count as often or as rarely as they like.
• eBird collects checklists of the birds people see. When an unusual bird is reported, regional reviewers look at the record, so a photo of a November hummingbird is worth taking.

Georgia DNR adds one more reason to keep a feeder up: a wintering hummingbird that visits a feeder this year may return next year.

Taking the Feeder Down: Cleanup and Storage

When the two weeks are up, the end-of-season routine is short:

• Pour out the nectar. Audubon says to always discard unused nectar when you take a feeder down for cleaning. Do not save the last batch for spring.
• Clean every part. Take the feeder apart and scrub the reservoir, ports, and any bee guards.
• Let it air dry. Mississippi State Extension’s cleaning steps end with rinsing and letting the feeder air dry. Store it only once every part is completely dry.
• Store it where it stays clean. A closed bin or a box on a shelf keeps dust and insects out over the winter. Keep the small parts together so nothing is missing in spring.
• Plan to wash it again before it goes back out. A feeder that sat in storage all winter should be washed again before the first fill of spring.

If a feeder cracked, leaked, or was hard to clean this year, use the off-season to shop for a replacement that comes apart easily.

Keep Helping After the Feeder Comes Down

A feeder is a supplement. Audubon’s FAQ calls native flowering plants the best source of nectar for hummingbirds, with a well-tended feeder adding sustenance during nesting season and migration. Alabama Extension suggests planting flowers that bloom in fall to help hummingbirds during migration, and notes that hummingbirds need a lot of protein, especially during migration. Washington’s wildlife department says they get that protein from aphids, small insects, and spiders. Leaving late-blooming plants standing keeps nectar and insects in the yard after the feeder is put away.

Fall is also a good time to note what worked this year: which spot drew the first visits, which plants the birds used, and when the last bird left. Those notes make next spring easier.

How We Put This Guide Together

We read the hummingbird pages of state wildlife agencies, state university extension services, Mass Audubon, the National Audubon Society, Smithsonian’s National Zoo, and Project FeederWatch, and kept a date or claim only when we could match it to the page we linked. Where sources disagree, we show both and lean toward keeping the feeder up longer, because the National Zoo says a clean feeder left up past its guidelines does no harm. We did not use commercial date charts, because they rarely say where their dates come from. Our general method is on the How We Review page.

Fall Hummingbird Feeder FAQ

What happens if you stop feeding hummingbirds?

Your summer birds will not be stranded, because hummingbirds leave on a schedule set by day length, not food supply. What you lose is a refueling stop for migrants still passing through, which Purdue and Ohio State Extension both say helps them on the journey. Hummingbirds also feed on flowers and insects, so a yard with late-blooming plants still offers something after the feeder comes down.

A hummingbird showed up in November. Should I put my feeder back out?

Audubon’s FAQ supports feeding a bird that stays past migration, as long as you keep the nectar from freezing and keep the feeder clean. Put out a small, fresh fill and change it on schedule. If you are in Georgia, report the bird to Georgia DNR; elsewhere, log it on eBird or FeederWatch, with a photo if you can get one.

Is a late-fall hummingbird in the East a Ruby-throated?

Often not. FeederWatch says winter hummingbirds in the Gulf Coast states and the Southeast are likely Rufous Hummingbirds, and Georgia DNR says most of its winter hummingbirds are western visitors. Both warn that these birds are hard to identify by sight, so treat a photo and a report as the way to find out.

Should I leave the feeder up but empty after the season?

We would not. An empty feeder offers nothing to a late migrant, and one left outdoors all winter will need a full cleaning before spring anyway. Either keep it up with fresh nectar on the two-week rule, or empty it, clean it, and store it dry.

Final Thoughts

Watch for the last visit, wait two weeks, and keep the nectar fresh until then. In the North that usually means a feeder comes down in late September or October; in the middle of the country, late October; along the Gulf Coast, November or not at all. If a late bird turns up, feed it with nectar that stays liquid and report it. For nectar, cleaning, and placement guides, see our Hummingbird Feeders section.
