How the Alaska season unfolds
Arrival · April 15 males first
Adult males arrive ahead of females to claim territory. Have feeders out 1–2 weeks before April 15 — the earliest birds arrive depleted, and a ready feeder can anchor them to your yard for the season.
Nesting · May 5 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 10–August 5 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 5 stragglers
Juveniles and late movers trickle through until September 5. Leave feeders up until September 20 — about two weeks past the typical last bird — as a refueling stop for stragglers.
Hummingbird species in Alaska
| Species | Status in Alaska |
|---|---|
| Rufous Hummingbird | breeding, Southeast & Southcentral coasts |
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.
Feeding Alaska’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 April 3 (about two weeks before first arrivals); take them down around September 20. Migration runs on day length, so a feeder never delays a bird.
Your Alaska feeder calendar
Every date below is computed from Alaska’s own arrival and departure anchors — no generic advice, these are your dates:
| Feeder task | Typical Alaska date | Why then |
|---|---|---|
| Hang feeders | April 3 | ~2 weeks before first arrivals (April 15) — early males arrive depleted |
| Expect the nesting lull | May 5 onward | Females switch to insects; traffic dips but the birds haven’t left |
| Add a second feeder | June 26 | ~2 weeks before departures begin — migrants stack on top of locals |
| Peak nectar demand | July 10 – August 5 | Birds double body weight for the trip; busy yards drain a feeder daily |
| Take feeders down | September 20 | ~2 weeks after the last stragglers (September 5) |
Plant a yard in Alaska 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 10–September 5 migration crush:
- Penstemon (beardtongue)
- Salvia and autumn sage
- Scarlet gilia
- Agastache (hummingbird mint)
- Desert willow / ocotillo (Southwest)
Skip pesticides where you can — hummingbirds feed heavily on gnats, fruit flies, and spiders, especially females raising young.
