Fall Bird Migration in Alaska

Alaska runs its autumn early: at the old dairy farm inside Fairbanks, a second sowing of barley is timed to come up just as the fall migration peaks in August, with cranes and geese on the fields.

Public viewing sites in Alaska

Every place below is one an agency itself describes for watching the fall passage, with the agency named and linked, the species it documents there, the months it names as the peak, and the facility that exists: a tour route, a platform, a tower, a visitor centre. Where the agency wrote a sentence worth reading, it is quoted exactly.

Creamer's Field Migratory Waterfowl Refuge StateMarquee site

A former dairy farm inside Fairbanks, its fields planted in barley, wheat, oats and field peas, with over 25 miles of trails

Sandhill crane

The department manages the fields as a feeding stop, clearing snow and spreading barley in spring and sowing a second barley crop in late July or early August so the new shoots come up as the fall migration peaks. Viewing platforms look out over the fields, and the department bands ducks, geese and cranes here in both migrations.

“A second planting of barley in late July or early August produces tender new shoots just as fall migration peaks.”

The coloured grid is where people have uploaded a verified sandhill crane record to iNaturalist in September, October, November and December, brighter where more have been logged. It is a map of reports rather than of birds: it thickens around refuges, car parks and towns because that is where observers stand, and it shows past reports rather than birds present today. Pins are public viewing sites an agency itself describes; grey dots are US Fish and Wildlife Service refuges and hatcheries, drawn because the refuge system is where most of the staging happens.

When

When the passage peaks in Alaska

Alaska Department of Fish and Game, Creamer's Field Migratory Waterfowl Refuge puts the Alaska peak at August into September, timed by the refuge to the late July or early August barley planting that greens up as migration peaks. That describes a pattern across past autumns. The week itself swings with the weather: a cold front to the north moves cranes and geese south in a single night, and a warm spell holds them for weeks. Dawn and the last hour before dusk are when cranes and geese move between the fields and the water, and that movement is the spectacle the platforms are built for.

Alaska runs its autumn on a calendar two months ahead of the lower 48. At Creamer's Field, an old dairy farm inside Fairbanks that became a refuge when the fields turned out to be what the migration wanted, the Department of Fish and Game plants a second barley crop in late July or early August so the tender new shoots come up exactly as the fall migration peaks. Viewing platforms look out over those fields, and the department bands ducks, geese and cranes here in both migrations. More than 25 miles of trail run the refuge. There is no fall hawk count anywhere in the state; the one Alaskan station counts in spring.

Below, one curve per species the agencies document in Alaska: every research grade observation members of the public have uploaded to iNaturalist for the state, by calendar month across every year the platform holds, with September to December shaded. Counts of uploads, so they measure observers as well as birds, and the shape is worth reading where the absolute numbers are not.

Sandhill crane

1,504 research grade sandhill cranes observations have been uploaded to iNaturalist for Alaska across every year the platform holds, and 11 percent of them fall in the four shaded autumn months. The busiest month in the record is May. An autumn month carries about 0.25 times as many uploads as an average month outside autumn. People upload most of everything in July, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

The movement is watched from the designated pullout or platform: the birds settle on shallow water for the night, and the roost itself is the one place a viewing site is never placed. “Sandhill cranes flying over Sherburne National Wildlife Refuge (24542820818)” by USFWS Midwest Region from United States, CC BY 2.0
Latest reports

What people have reported in Alaska lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for Alaska, as a date and the platform’s own coarse locality. Evidence that people do find sandhill crane here. Each is one bird on one past day: the flocks move with the weather, so where they are this week is what the agency page and its counts answer.
