Hummingbirds in Alaska in Winter
Hummingbirds are extremely rare in Alaska during winter. Most migrate south by September, but a small number of Rufous Hummingbirds may overwinter in coastal Southeast Alaska if they find heated feeders. Your best odds are in areas like Juneau or Ketchikan where milder ocean temperatures and maintained feeders keep them alive.

1. Why are hummingbirds so rare in Alaska during winter?
Alaska’s harsh winter climate makes survival nearly impossible for hummingbirds. The only species that occasionally tries to overwinter is the Rufous Hummingbird, but they depend entirely on artificial feeders to stay alive. Without a reliable source of sugar water, they would starve or freeze within hours. Most Rufous Hummingbirds migrate to Mexico or the southern U.S. before the first frost.

2. Where in Alaska might you see a hummingbird in winter?
Your best chance is in Southeast Alaska, especially coastal towns like Juneau, Ketchikan, and Sitka. These areas benefit from temperate ocean currents that keep temperatures slightly above freezing. Pay attention to backyards with heated hummingbird feeders. Some homeowners in these regions maintain feeders year-round and have reported overwintering Rufous Hummingbirds.

3. What time of day are winter hummingbirds most active?
Even in winter, hummingbirds feed during daylight hours. They need to eat every 15-20 minutes to maintain their high metabolism. The best time to spot one is mid-morning after the sun has warmed the air slightly, or late afternoon before they enter torpor for the night. Feeder activity peaks when temperatures are above 25°F (-4°C).
4. How can you identify a winter hummingbird in Alaska?
The most likely overwintering hummingbird is the Rufous Hummingbird. Look for a small, stocky bird with an orange-brown back, rufous sides, and a coppery-green crown. Males have a bright orange-red throat that can appear dark in low light. Females are more green above with rufous flanks.

5. What do hummingbirds eat in Alaska's winter?
Natural nectar sources are absent in winter, so these birds rely entirely on sugar water from feeders. Some also eat tiny insects that may be dormant in sheltered spots, but this provides minimal energy. The sugar concentration in feeders should be 1 part white sugar to 4 parts water (20% sugar) to mimic natural flower nectar. Never use honey, artificial sweeteners, or red dye.
6. How to prepare your backyard for winter hummingbirds in Alaska?
If you want to attract or support a winter hummingbird, place feeders in a sheltered area protected from wind and snow. Use a feeder with a built-in heating element or wrap the feeder in a string of Christmas lights to keep the liquid from freezing. Clean the feeder every 2-3 days with hot water and a brush.
