Taking Down a Hummingbird Feeder by Date Can Miss Migrants

The hummingbird feeder hangs quiet after a cool September morning. Remove it about two weeks after your last local hummingbird sighting, not on a fixed calendar date; leaving it up does not delay migration.

Use sightings and frost to pick your feeder date

The best removal date is usually 14 days after your last hummingbird sighting, unless local records show winter visitors. Check recent reports through the Cornell Lab of Ornithology, eBird, or a local Audubon chapter when a bird appears after your usual season.

Regional timing is only a starting point

Regional windows help you plan, but your own last sighting matters more than a national date, especially where elevation and coastal weather change conditions quickly.

A fixed date can miss late birds

Do not remove a feeder on Labor Day or October 1 without checking conditions: a late Ruby-throated Hummingbird in the East may need one more stop, while a Rufous Hummingbird in Oregon may be a normal winter visitor.

Keep a winter feeder only when it stays safe

Keep a hummingbird feeder through winter only where local records show wintering hummingbirds and you can provide plain, liquid nectar checked daily during freezing weather.

Rufous and Anna's change the rule

A Rufous Hummingbird in winter is not automatically lost or injured: the species has expanded winter records in southern and coastal areas, while Anna’s Hummingbirds are year-round residents across much of California.

Migration is not caused by feeder removal

Leaving a hummingbird feeder up will not make hummingbirds skip fall migration because day length is a major seasonal signal, while food helps birds build energy for travel.

Fresh nectar matters more than winter dates

A safe feeder uses a 4:1 sugar-water nectar ratio: four parts water to one part plain white table sugar. Never add extra sugar, honey, red dye, corn syrup, or antifreeze.

Change nectar by temperature

Replace nectar every 1 to 2 days above 80°F, every 2 to 3 days between 70°F and 80°F, every 3 to 5 days between 60°F and 70°F, and at least every 5 to 7 days in cooler weather.

Stop pests without changing nectar

Use an ant moat, repair leaks, move the feeder away from wasp-heavy flowers, and bring it indoors at night if mammals raid it. Do not use pesticides, oil, petroleum jelly, or sticky products near feeding ports because they can harm feathers and tongues.

Once you choose a hummingbird feeder removal date, clean the feeder before putting it away rather than storing old nectar residue until spring. Take apart removable ports and bases, wash all surfaces with hot water and a small feeder brush, rinse thoroughly, and let every piece air-dry completely. Store the dry feeder disassembled in a clean, dry place, and inspect it for cracks, warped parts, or clogged ports before the next fall hummingbird migration.

A hummingbird feeder's frost risk is not only about frozen nectar: repeated freezing can expose leaks or damage worn plastic, so checking the feeder before reuse helps keep the next batch of 4:1 nectar safe.

Common questions

What month should I take down hummingbird feeders?

Take it down 14 days after your last confirmed sighting, often late September through October in the Northeast, Midwest, and Great Lakes. Keep it longer in mild regions with documented winter birds.

Should I leave my hummingbird feeder out in winter?

Leave it out only if winter hummingbirds occur locally and you can keep nectar liquid below 32°F. Use two feeders to rotate a thawed one into place during cold mornings.

Will leaving a feeder up stop hummingbirds from migrating?

No, a hummingbird feeder does not stop migration because seasonal day length is the main trigger. Fresh nectar can support late migrants and winter visitors.

What animal empties a hummingbird feeder at night?

Raccoons are frequent nighttime raiders, while bears can damage feeders in bear-active areas. Bring the feeder inside at night or use physical barriers if losses occur.

How often should I clean a hummingbird feeder in cool weather?

Clean it every time you replace nectar, usually every 5 to 7 days in cool conditions. Clean it immediately if nectar turns cloudy, smells sour, or shows mold.

Make the call from your own yard

Remove the feeder after 14 quiet days if your region has no winter hummingbird records. Keep one available for a local winter bird only if you can provide liquid 4:1 nectar, regular cleaning, and predator-safe placement.
