Fall Bird Migration in North Dakota

North Dakota is where the Central Flyway gathers before it runs south, and the refuge south of Bismarck describes an autumn sky filled with sandhill cranes, shorebirds, ducks, geese and swans.

Public viewing sites in North Dakota

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.

The refuge writes autumn as its own season, with sandhill cranes, shorebirds, ducks, geese and swans overhead, and notes that whooping cranes occasionally stop in the area to feed and rest on the way south. Late fall usually ends it.

“Autumn is a spectacular season as days turn cooler and the skies are filled with sandhill cranes, shorebirds, ducks, geese, swans, and pelicans.”
U.S. Fish and Wildlife Service, Long Lake National Wildlife Refuge, quoted exactly.

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 North Dakota

U.S. Fish and Wildlife Service, Long Lake National Wildlife Refuge puts the North Dakota peak at September through November, with the refuge calling autumn its spectacular season before the birds are moved on. 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.

North Dakota is where the Central Flyway gathers before it runs south, and Long Lake, a shallow alkali lake in native prairie south of Bismarck, writes autumn as its own season: skies filled with sandhill cranes, shorebirds, ducks, geese, swans and pelicans, with whooping cranes stopping occasionally to feed and rest on the way through. The refuge is honest about the end of it too, noting that late fall usually finds the weather telling the birds to move on. The other North Dakota refuges publish year round species lists rather than seasonal calendars, so none of them fixes a second site to a month.

Below, one curve per species the agencies document in North Dakota: 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

36 research grade sandhill cranes observations have been uploaded to iNaturalist for North Dakota across every year the platform holds, and 39 percent of them fall in the four shaded autumn months. With fewer than 60 records the series is too thin to summarise, so the bars stand on their own. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Whooping crane

19 research grade whooping cranes observations have been uploaded to iNaturalist for North Dakota across every year the platform holds, and 47 percent of them fall in the four shaded autumn months. With fewer than 60 records the series is too thin to summarise, so the bars stand on their own. 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 North Dakota lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for North Dakota, as a date and the platform’s own coarse locality. Evidence that people do find sandhill crane and whooping 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.
