when do hummingbirds leave
Most hummingbirds leave in late summer to early fall, with the heaviest migration usually from late August through September, depending on your region and the species in your yard.
Quick Scoop
- In most of the U.S. and Canada, hummingbirds begin heading south late August through September , sometimes into early October if weather and food stay good.
- Males usually leave first , often a week or two before females and juveniles.
- The farther north you live, the earlier they tend to leave (often late August to early September). Farther south, they may stick around into October or even overwinter in mild coastal areas.
- Typical fall migration window by species:
- Ruby-throated: AugustâOctober.
* Rufous: JuneâAugust (West, high latitudes), often gone by early fall.
* Allenâs and Black-chinned: roughly JulyâSeptember.
Simple rule of thumb
- Keep feeders up for at least 2 weeks after you see your last hummingbird , in case late migrants pass through.
- If youâre in the far north: expect most to be gone by early to midâSeptember.
- In mid-latitude states: many leave in September , some into early October.
- In the far south or very mild coastal areas: some may stay into October or later , and a few may overwinter.
Regional timing snapshot (examples)
| Region / Example | Typical âleavingâ time |
|---|---|
| Northern U.S. & Canada | Late Augustâearly/mid September, before frost kills flowers and insects. |
| Upper Midwest (e.g., Michigan, Ohio) | Late Augustâearly October, many gone by mid/late September. |
| Mid-South (e.g., Alabama, Arkansas) | Often midâlate September into early October. |
| Southwest / Texas | Can see birds into October; some linger longer in warm areas. |
| West Coast | Some populations migrate JulyâSeptember; a few coastal birds may stay all winter. |
Why they leave when they do
- Food decline: Fewer flowers and insects as days shorten and temps drop.
- Weather: They avoid freezing conditions that wipe out nectar sources.
- Breeding cycle: Once chicks are raised and independent, adults head south to wintering grounds in Mexico, Central America, or the southern U.S., depending on species.
If your feeder suddenly gets quieter in late August or September, it usually means males have already gone and females/young are following, not that you did anything wrong.
Tiny backyard story (to visualize it)
Imagine youâre watching your feeder in late August:
- One week you see a busy cloud of flashy males; the next week, mostly females and youngsters remain.
- A couple of weeks later, visits slow to just one or two shy birds at dusk. Then, one crisp morning, no one shows up at allâthatâs usually your sign that your âsummer jewelsâ have finally slipped south on their long overnight journey.
