Hummingbird Migration in Oregon: 2026 Timing

Q: When do hummingbirds leave Oregon?

Adult males start south around July 15; the main departure wave passes about August 20, and the last stragglers — usually juveniles — trickle through until September 25. Some western species winter here, so a late hummingbird isn't necessarily lost.

Q: When should I take my hummingbird feeders down in Oregon?

Don't take them down — Oregon hosts hummingbirds in winter. Keep at least one feeder clean and full year-round, and you may host a rare western species in December.

Q: When do hummingbirds arrive in Oregon?

First males typically show up around February 20, with most feeders active by March 20. Put feeders out a week or two before the first typical arrival — early birds arrive hungry.

Q: What hummingbird species live in Oregon?

Anna's Hummingbird (year-round, west of the Cascades); Rufous Hummingbird (breeding, March–September); Calliope & Black-chinned (east-side breeders).

Q: What is the correct hummingbird nectar recipe?

One part plain white sugar to four parts water. No red dye (unnecessary and possibly harmful), no honey (ferments into toxins), no sugar substitutes. Change nectar every 2–3 days in warm weather, every 4–5 in cool weather, and rinse the feeder with hot water each refill.

Q: Why did my hummingbirds suddenly disappear in midsummer?

Almost always nesting, not leaving. Females go quiet while incubating and switch to insects for protein; males guard flower territories away from feeders. Traffic typically roars back in late summer when fledged juveniles and early migrants arrive together.

The season, phase by phase

How the Oregon season unfolds

Arrival · February 20 males first

Adult males arrive ahead of females to claim territory. Have feeders out 1–2 weeks before February 20 — the earliest birds arrive depleted, and a ready feeder can anchor them to your yard for the season.

Nesting · March 20 onward quiet weeks

Feeder traffic often dips while females nest — they're eating small insects for protein and staying close to the nest. The birds haven't left; they're busy. Keep nectar fresh through the lull.

The rush · July 15–August 20 peak chaos

The best feeder weeks of the year: local families plus southbound migrants stack up together, all trying to double their body weight for the trip. A busy yard can drain a feeder daily. Adult males slip out first.

Last calls · through September 25 stragglers

Migrants taper off, but this is a winter-hummingbird state: keep at least one feeder clean and full all winter and you may host a rare western species in December.

Hummingbird species in Oregon

Species	Status in Oregon
Anna's Hummingbird	year-round, west of the Cascades
Rufous Hummingbird	breeding, March–September
Calliope & Black-chinned	east-side breeders

The West runs a relay of species rather than a single act — resident breeders hold territories while rufous and calliope migrants pour through on the Rocky Mountain corridor in late summer, briefly stacking three or four species at one feeder.

Feeder protocol

Feeding Oregon’s hummingbirds, done right

The only recipe

1 part white sugar : 4 parts water. Nothing else — no red dye, no honey (it ferments into toxins), no substitutes. Red on the feeder does the attracting.

Keep it clean

Change nectar every 2–3 days in warm weather and rinse with hot water each refill. Cloudy nectar or black mold can be lethal — when in doubt, dump it.

The calendar

Hang feeders around February 8 (about two weeks before first arrivals); leave at least one up all winter. Migration runs on day length, so a feeder never delays a bird.

Every date below is computed from Oregon’s own arrival and departure anchors — no generic advice, these are your dates:

Feeder task	Typical Oregon date	Why then
Hang feeders	February 8	~2 weeks before first arrivals (February 20) — early males arrive depleted
Expect the nesting lull	March 20 onward	Females switch to insects; traffic dips but the birds haven’t left
Add a second feeder	July 1	~2 weeks before departures begin — migrants stack on top of locals
Peak nectar demand	July 15 – August 20	Birds double body weight for the trip; busy yards drain a feeder daily
Winter protocol	Never	Winter hummingbird state — one clean, full feeder year-round

Beyond the feeder

Plant a yard in Oregon they’ll fight over

Feeders are the appetizer; flowers and the small insects they attract are the meal. These western natives carry a yard through the July 15–September 25 migration crush:

Penstemon (beardtongue)
Salvia and autumn sage
Scarlet gilia
Agastache (hummingbird mint)
Desert willow / ocotillo (Southwest)

Wild bergamot (bee balm) blooming at a meadow edge — Wild bergamot — the native bee balm. One established patch outdraws any feeder in Oregon by midsummer.

Skip pesticides where you can — hummingbirds feed heavily on gnats, fruit flies, and spiders, especially females raising young.
