When to go
Alaska is too large for one statewide season chart. Use these month guides as planning context, then check the specific destination, managing agency, and recent observations before traveling.
winter
6 hr daylight*January is Alaska's coldest and darkest month, but resident species are still active. Willow and Rock Ptarmigan in full white plumage forage along roadsides, while Bald Eagles congregate near open water. Short daylight windows demand efficient planning but reward dedicated birders with boreal specialties.
winter
9 hr daylight*Daylight increases noticeably through February and resident birds begin early courtship behaviors. Boreal Owls and Great Horned Owls start calling at dusk, while ptarmigan remain common along mountain roads. This is an excellent month for winter owl surveys in the boreal forest.
spring
12 hr daylight*March marks the slow transition toward spring as daylight surpasses 12 hours and the first waterfowl begin returning to coastal Alaska. Resident raptors like Gyrfalcon may still be seen hunting ptarmigan on windswept ridges. Early migrants trickle in along the southern coast.
spring
15.5 hr daylight*April accelerates migration across Alaska. Massive flocks of waterfowl stage on coastal wetlands and shorebirds begin arriving on tidal mudflats. Sandhill Cranes pass through in impressive numbers, and the first songbirds appear in Southeast forests.
spring
19 hr daylight*May is one of Alaska's most exciting birding months. Shorebird migration peaks on the coast with spectacular concentrations of Western Sandpipers and Dunlin. Arctic breeders arrive in Nome, and seabird colonies activate on coastal cliffs. The entire state pulses with avian activity.
summer
21.5 hr daylight*June is the start of Alaska's peak birding season. Nearly 24 hours of daylight provide endless opportunities. Puffin colonies are bustling, tundra breeders are on territory around Nome, and boreal songbirds are in full song across the interior forests.
summer
20 hr daylight*July offers peak summer birding across Alaska. Seabird colonies are at maximum activity, shorebird chicks are hatching on the tundra, and Humpback Whales attract seabirds to feeding frenzies in coastal waters. Denali's alpine zones are accessible and alive with breeding birds.
summer
17 hr daylight*August marks the transition from breeding season to early fall migration. Southbound shorebirds begin staging on mudflats, and juvenile birds appear everywhere. Salmon runs peak, drawing massive concentrations of Bald Eagles and gulls to rivers and streams.
fall
13.5 hr daylight*September is Alaska's premier fall migration month. Massive flocks of Sandhill Cranes stage in the interior, raptors push through mountain passes, and waterfowl gather on lakes and wetlands before heading south. Tundra and boreal forests blaze with fall color.
fall
10.5 hr daylight*October sees the final waves of migration as most songbirds and shorebirds have departed. Waterfowl continue moving through in large numbers, and Bald Eagles begin congregating at late salmon runs. The Chilkat Bald Eagle Preserve near Haines starts its legendary eagle gathering.
fall
7.5 hr daylight*November often brings the seasonal peak of the Chilkat Bald Eagle congregation near Haines as eagles gather around late chum salmon runs. Actual numbers vary from year to year with salmon availability, weather, river conditions, and timing.
winter
5.5 hr daylight*December is Alaska's darkest month, with as little as 5 hours of daylight in Anchorage and near-total darkness in the far north. Hardy birders can find ptarmigan, boreal owls, and winter finches. Christmas Bird Counts provide organized birding opportunities across the state.
