The hummingbirds of Alaska

Rufous Hummingbird

Rufous Hummingbird

Selasphorus rufus

Summer nester in Alaska.

How to recognize it: Male is bright orange-copper with a scarlet throat; females green above with rusty flanks and tail base.

Breeds farther north than any other hummingbird, into southeast Alaska, and is famous for chasing every other hummingbird off a feeder. A few winter along the Gulf Coast each year.

When to put out hummingbird feeders in Alaska

Scouts reach Alaska around April 20, a little earlier in the south of the state and later at elevation. Males travel ahead of females by a week or more and arrive before many native flowers open, so a feeder hung two weeks early, by April 6, gets used. Across 13 Alaska cities in the NOAA 1991–2020 normals, the typical last spring freeze falls around May 16, after the first hummingbirds arrive. Expect a few frosty nights with birds already here; bring feeders in if they freeze and rehang them at first light.

When to take hummingbird feeders down in Alaska

Leaving feeders up does not keep hummingbirds from migrating; day length triggers departure. Adults leave first, then juveniles, and late stragglers from farther north pass through after your own birds have gone. In Alaska most have left by August 31. Keep at least one feeder clean and filled until September 14, two weeks after the last bird you see.

Native flowers for hummingbirds in Alaska

Feeders bring hummingbirds in; flowers and the insects on them keep them nesting nearby. These natives grow in Alaska (USDA 1a–8a):

  • Salmonberry (Rubus spectabilis): Spring flowers for Rufous Hummingbirds, early fruit for thrushes.
  • Fireweed (Chamaenerion angustifolium): Tall magenta spikes are a key northern hummingbird flower.

Nectar and cleaning

  • Mix 1 cup plain white sugar into 4 cups water; boiling is optional if you use clean water and change it on schedule.
  • No red dye, honey, brown sugar or sweeteners. A red feeder is enough to attract them.
  • Change nectar every 2 days above 80°F, every 4–5 days in cooler weather; cloudy nectar has fermented.
  • Scrub ports with a bottle brush at each change; soak monthly in 1 part vinegar to 4 parts water.
  • Use an ant moat and keep feeders out of full afternoon sun to slow spoilage.

Frequently asked

What hummingbirds live in Alaska?

Alaska has one regular hummingbird, the Rufous Hummingbird (summer nester).

When should I put out hummingbird feeders in Alaska?

Hang feeders by about April 6. The first hummingbirds usually reach Alaska around April 20, and early birds find little in bloom.

When should I take hummingbird feeders down in Alaska?

Most leave by about August 31. Keep feeders up until September 14, two weeks after the last one you see; a feeder does not stop birds from migrating.

Can hummingbirds handle a late frost in Alaska?

The typical last spring freeze across Alaska cities is around May 16. Hummingbirds survive cold nights by dropping into torpor, but nectar feeders matter most when flowers are frosted. Bring a feeder in overnight if it freezes solid and rehang it at dawn.

What is the right sugar water ratio?

One part plain white sugar to four parts water, no red dye, no honey. Change it every two days when highs are above 80°F and every four to five days in cooler weather.
