Hummingbird Migration - According to Google

Hummingbirds fly south for the winter in a staggered migration that begins as early as late June or July and lasts through October

General Migration Timeline
Northern and Western Areas: Long-distance travelers like the Rufous hummingbird start moving south as early as late June or July. (That's me, and my feeders are not emptying as fast)

Mid-Atlantic and Northern US: First departures begin in mid-to-late August, with peak movement in September.

Southeast and Gulf Coast: Most birds pass through or gather in September and October before heading into Mexico or Central America

Departure Order by Group
Adult males: Leave first, often in late July or August, because they do not help raise the young.

Adult females: Follow about one to two weeks later.

Juveniles: Young birds leave last, usually in September, after building up enough fat and weight for the journey

When to Take Down Feeders
Leave your feeders up until you have not seen a single hummingbird for two to three weeks.

Leaving feeders up will not stop a hummingbird from migrating; it simply provides vital fuel for late travelers and young stragglers

My note - it is Sep 24 and I still see birds at my feeders... they don't wear name tags so I don't know if the ones still here are adults or young ones getting ready to fly South for the first time... either way, I keep my feeders up until the weather starts freezing overnight, then I clean them and store them away so they don't freeze and break... next year they will go up in 'about' March when the risk of freezing is gone

    I keep notes about what I need to do, and what I've done... some in a text file and some in a spreadsheet when I want a formula to track intervals... I started tracking feeder fillings in June after I replaced my two small feeders with the three 20 ounce ones I now have... one in the front visible from the kitchen window and two in the back about 20 feet apart and visible from my office chair

    When I started there were evidently a lot of birds visiting in the back because I was filling one of the two feeders every 4 days... then at the end of July the frequency dropped a lot... I will *guess* that means that some number of birds left to go toward Mexico and/or South America... I am also going to guess that my most recent fills MAY be the last ones this year

    Right now (9-28-26) the feeder levels are still slowly going down and I *sometimes* see a bird at one of the feeders, so I may need to do more fillings in October... time, and the weather, will show the proof of needing to fill again

    What kind of feeders do you use? I’m in the San Francisco Bay Area, and my feeders always seem to get moldy before the hummies have finished the nectar. Then when the mold develops, they won’t come near it...

    When my feeders (I have 3) get empty I use vinegar and a toothbrush to reach inside to completely scrub everything… then I rinse 7 times with hot water to make sure no vinegar residue remains… you are in a generally warmer and more humid area (I am on Vancouver WA just North of Portland OR) so I can understand having a mold problem
