US Fall Hummingbird Migration Map & Schedule: When to Keep Feeders Up in Your Region

Keep your hummingbird feeders clean, refilled, and hanging until two full weeks after you spot the last migrating bird in your yard—typically between late September and mid-November across most US states. Feeders do not delay migration; rather, they provide critical calorie boosts during chilly autumn twilights.

| Criteria | Late Summer Prep (Aug - Early Sept) | Early Frost Snaps (Late Sept - Oct) | Late Autumn Stragglers (Nov - Dec) |

| --- | --- | --- | --- |

| Ambient Temperature Range | 70°F to 90°F+ | 40°F to 65°F | Below 40°F (Frost Risk) |

| Nectar Sugar Ratio | 4:1 (Water to White Sugar) | 4:1 to 3.5:1 | 3:1 (Lower Freezing Point & High Calories) |

| Feeder Lighting Needs | Standard Daylight Viewing | Solar Dusk RGB Lighting (Vital for Dim Evenings) | Solar Night Glow & Dawn Swap-Outs |

| Refill & Cleaning Frequency | Every 2 to 3 Days | Every 4 to 5 Days | Every 5 to 7 Days (if unfrozen) |

| Primary Avian Goal | Hyperphagia Fat Mass Doubling | Migration Waypoint Refueling | Emergency Fuel for Late Stragglers |

As ambient temperatures drop from late summer through late autumn, nectar ratios, cleaning routines, and lighting needs require specific adjustments.

Expert Tip: Extending Twilight Energy Windows with Illuminated Solar Feeders

Dr. Elizabeth Vance, Avian Migration Specialist: "Hummingbirds operate on a precise energetic knife-edge during fall migration. As autumn daylight contracts rapidly, twilight hours become intense feeding rushes before nocturnal roosting. Solar-illuminated feeders, like hand-blown glass models with integrated RGB lights, provide essential visual cues during dim dusk hours without disrupting circadian roosting habits."

5 Critical Fall Hummingbird Feeding Mistakes to Avoid

Avoid these frequent errors that compromise bird safety during the fall migration season:

Premature Feeder Removal: Taking feeders down in August out of fear that nectar availability prevents birds from migrating. (Migration is driven by instinct and daylight length, not food).

Using Red Dye or Artificial Preservatives: Adding food coloring or chemical solutions that damage liver function during high-volume feeding.

Ignoring Morning Freeze Slush: Letting nectar slush over during chilly nights instead of swapping in warm 3:1 nectar at dawn.

Taking Feeders Down Too Quickly After Sighting: Storing feeders after 2–3 days without sightings, leaving late-migrating stragglers without fuel.

Neglecting Feeder Cleanliness in Cooler Weather: Assuming cold air prevents mold growth; bacteria still build up in perches and ports over time.

US Hummingbird Species Departure Windows & Flyway Routes

| Species | Primary Summer Range | Peak Fall Departure Window | Wintering Grounds | Flyway Corridor |

| --- | --- | --- | --- | --- |

| Ruby-throated Hummingbird | Eastern & Central US, Southern Canada | Late August – Mid-October | Central America / Gulf Coast | Atlantic & Mississippi Flyways |

| Rufous Hummingbird | Pacific Northwest, Northern Rockies, Alaska | July – September | Mexico / Gulf Coast / Southeast | Pacific & Central Flyways |

| Black-chinned Hummingbird | Western US, Intermountain West | August – Late September | Western Mexico | Central & Pacific Flyways |

| Broad-tailed Hummingbird | Rocky Mountain Region | August – Early September | Highlands of Mexico | Central Flyway |

| Anna's Hummingbird | Pacific Coast (CA, OR, WA, BC) | Year-Round Resident (No Migration) | Pacific Coastal Strip | Pacific Flyway |

Understanding which species pass through your region helps predict when feeding frenzies will peak.

Month-by-Month Autumn Migration Progression (August through November)

• Late August — Hyperphagia begins. Adult males depart first; clean feeders and top off nectar every 3 days.

• September — Migration peak for females and juveniles. Solar RGB lighting extends feeding hours during early autumn twilights.

• October — Northern birds clear out. Shift nectar ratio to 3.5:1 or 3:1 in frost-prone zones. Inspect daily for slush.

• November — Monitor for late stragglers. Keep feeders hanging 14 days past your last sighting before winter storage.

Follow this monthly roadmap to adjust your yard care as birds journey south.

Frequently Asked Questions About Fall Migration & Late Feeding

How do I keep my hummingbird nectar from freezing during early autumn frost?

Adjusting the nectar ratio to 3 parts water and 1 part pure white cane sugar slightly lowers the freezing point while supplying higher energy density. Additionally, bring feeders indoors overnight during freeze warnings and hang them back out at dawn.

Should I change the nectar ratio from 4:1 to a richer solution in cold fall weather?

Yes, shifting from 4:1 to 3:1 in late fall is safe and beneficial. It helps southward migrants rapidly build fat reserves for long flights across the Gulf of Mexico or along Western corridors.

Do solar RGB lights on feeders startle migrating hummingbirds at night?

Soft LED illumination does not startle birds; instead, it extends feeder visibility during rapidly dimming autumn dusk hours when birds feed heavily before roosting overnight.

Which hummingbird species stay in the Pacific Northwest or Southwest all winter?

Anna's Hummingbirds along the Pacific Northwest coast and Costa's/Anna's Hummingbirds in the Southwest are year-round residents that require continuous winter feeder care.

Find clear answers to common questions about late-season hummingbird care.

Autumn Dusk Feeding vs. Daylight Hours Seasonal Calendar

| Month / Stage | Daylight Duration | Sunset Window | Peak Feeding Urgency | Recommended Lighted Feeder Role |

| --- | --- | --- | --- | --- |

| Late August | 13.5 Hours | 7:45 PM | Moderate Evening Staging | Visual attraction for passing high-altitude migrants |

| Mid-September | 12.2 Hours | 7:00 PM | High Twilight Hyperphagia | Solar RGB illumination guides late-dusk arrivals |

| Mid-October | 11.0 Hours | 6:15 PM | Critical Pre-Roost Fueling | Soft night-glow marks reliable energy station in dim light |

| Early November | 10.0 Hours | 5:00 PM | Emergency Straggler Refueling | High contrast illuminated glass helps lone wanderers |

As daylight contracts, twilight feeding becomes the most vital energy uptake window for southbound birds.

State-by-State & Regional Fall Departure Guidelines

• Northeast & New England (ME, VT, NH, MA, NY) — Peak departure occurs between Sept 10 and Oct 1. Keep feeders filled until at least Oct 20 to support Canadian migrants passing through.

• Upper Midwest & Great Lakes (MI, WI, MN, IL, OH) — Peak departure is mid-September. Maintain feeders through late October; watch for Rufous vagrants moving eastward.

• Mid-Atlantic & Southeast (PA, VA, NC, SC, GA, FL) — Migration stretches from mid-September through early November. Coastal areas host overwintering Ruby-throated and Rufous individuals; keep at least one feeder active all winter.

• Gulf Coast (AL, MS, LA, TX) — Fall migration peaks in October. Feeders should remain out continuously as many birds overwinter along the Gulf Coast.

• Pacific Northwest (WA, OR, Northern CA) — Migratory Rufous depart by September, but native Anna's Hummingbirds stay all winter. Do not take feeders down in the PNW!

• Southwest & Mountain West (AZ, NM, CO, UT, NV) — Mountain species depart in August/September. Desert and valley floors host year-round Anna's and Costa's species.

Regional departure timing varies by latitude, elevation, and wintering populations.

Your Autumn Yard Preparation Action Plan

Your decision: Determine whether you live in an overwintering zone (PNW/Southwest/Gulf Coast) or a seasonal migration corridor, and calculate your yard's target feeder removal date.

Do this next: Keep feeders filled with clean nectar, monitor late-afternoon visits, and leave feeders up at least 14 days after your last sighting.

• 14-Day Rule: Leave feeders hanging for two full weeks after the last observed hummingbird sighting before taking them down.
• Daylight Triggers Migration: Leaving nectar out will never trick hummingbirds into staying; migration is governed by sunlight patterns and internal biological clocks.
• Dusk Feeding Importance: Shorter autumn days create urgent evening feeding frenzies before overnight cold roosts.
• Richer Fall Nectar: Switch from a 4:1 ratio to 3:1 in frosty weather to lower the freezing point and deliver dense calories.
• Solar RGB Advantage: Hand-blown solar glass feeders illuminate at dusk, helping weary travelers spot food in low light.

Real-World Fall Feeding Scenarios & Troubleshooting

A sudden night frost is forecasted, but you spotted a juvenile hummingbird yesterday. — Mix a 3:1 nectar solution and bring the feeder inside overnight. Hang the thawed, illuminated feeder back outside 15 minutes before sunrise.

It has been 10 days since your last hummingbird sighting in mid-October. — Keep the feeder clean and filled for 4 more days. If no additional birds arrive by day 14, wash, dry, and store the feeder for winter.

You spot a Rufous hummingbird in Pennsylvania during late November. — This is a late-season vagrant. Keep a heated or frost-protected feeder active through December to help this bird survive cold snaps.

Solutions for practical late-season hummingbird feeding scenarios:
