Fall Bird Migration in Kansas

Kansas holds inland salt marsh in the middle of the Central Flyway, and the refuge that manages it calls the fall its most spectacular season, with geese and ducks in the hundreds of thousands by November.

Public viewing sites in Kansas

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.

Sandhill craneWhooping crane

The refuge names migration as the reason birders come, with flocks of geese and sandhill cranes moving through and whooping cranes among them. An auto tour road circles the Big Salt Marsh, open from an hour and a half before sunrise to an hour and a half after sunset.

“The fall, however, can be the most spectacular season, with geese and ducks numbering in the hundreds of thousands at their peak in November.”
U.S. Fish and Wildlife Service, Quivira National Wildlife Refuge, quoted exactly.

Sandhill craneSnow gooseWhooping crane

The refuge describes the southern migration in full swing in autumn, naming sandhill and whooping cranes among the birds using the reservoir, and calls large flocks of snow geese a common spectacle of the season. Once the lake freezes the numbers fall away.

“Large flocks of snow geese are a common spectacle this time of year.”

Viewing sites in Kansas, with the national wildlife refuges in the state drawn underneath. 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 Kansas

U.S. Fish and Wildlife Service, Quivira National Wildlife Refuge puts the Kansas peak at October and November, with the refuge putting the peak of the goose and duck concentration in November. 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.

Kansas has inland salt marsh in the middle of the continent, which is why the Central Flyway bends over it. Quivira calls the fall its most spectacular season outright, with geese and ducks in the hundreds of thousands peaking in November, and the refuge is a destination for the whooping cranes that come through with the sandhills. The auto tour road circles the Big Salt Marsh, open from an hour and a half before sunrise. Kirwin, in the north of the state, runs the same calendar on a reservoir, with large flocks of snow geese through the autumn until the lake freezes and the numbers drop away to bald eagles.

Below, one curve per species the agencies document in Kansas: 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

74 research grade sandhill cranes observations have been uploaded to iNaturalist for Kansas across every year the platform holds, and 66 percent of them fall in the four shaded autumn months. The busiest month in the record is November. An autumn month carries about 3.92 times as many uploads as an average month outside autumn. People upload most of everything in May, 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.

Snow goose

350 research grade snow geese observations have been uploaded to iNaturalist for Kansas across every year the platform holds, and 34 percent of them fall in the four shaded autumn months. The busiest month in the record is February. An autumn month carries about 1.02 times as many uploads as an average month outside autumn. People upload most of everything in May, 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.

Whooping crane

30 research grade whooping cranes observations have been uploaded to iNaturalist for Kansas across every year the platform holds, and 83 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 Kansas lately

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