Fall Bird Migration in Oklahoma

Oklahoma sits on the Central Flyway where it narrows, and two refuges an hour apart hold the autumn crowd: cranes and shorebirds over the salt flats in the north, four species of geese on the water in the west.

Public viewing sites in Oklahoma

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.

Salt Plains National Wildlife Refuge FederalMarquee site

Sandhill craneWhooping crane

The refuge describes sandhill cranes foraging in the wheat fields through the fall days, with whooping cranes among them in some years, and puts combined duck, goose and crane numbers near 400,000 at the peak of migration.

“Peak numbers of ducks, geese, and cranes can approach 400,000 during spring and fall migrations.”
U.S. Fish and Wildlife Service, Salt Plains National Wildlife Refuge, quoted exactly.

Washita is a wintering ground for four species of goose and more than twenty species of duck, and the refuge counted almost 145,000 geese in its record year. An auto tour route runs the refuge.

“Canada geese, snow geese, Ross's geese, and greater white-fronted geese gather in great numbers at the refuge”

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 Oklahoma

U.S. Fish and Wildlife Service, Salt Plains National Wildlife Refuge puts the Oklahoma peak at October through December, when duck, goose and crane numbers at Salt Plains can approach 400,000 and the western refuge fills with wintering geese. 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.

Oklahoma sits where the Central Flyway narrows over the southern plains, and its two autumn refuges are different birds on the same calendar. Salt Plains in the north is a shallow salt lake with bare flats around it, and the refuge describes sandhill cranes foraging the wheat fields through the fall days, whooping cranes among them in some years, and a combined duck, goose and crane peak approaching 400,000. Washita in the west is the goose ground: four species winter on the upper end of Foss Reservoir, and the refuge's record year counted almost 145,000 of them flying off the water. Both are worked from a vehicle.

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

168 research grade sandhill cranes observations have been uploaded to iNaturalist for Oklahoma across every year the platform holds, and 65 percent of them fall in the four shaded autumn months. The busiest month in the record is November. An autumn month carries about 3.79 times as many uploads as an average month outside autumn. People upload most of everything in April, 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

149 research grade snow geese observations have been uploaded to iNaturalist for Oklahoma across every year the platform holds, and 38 percent of them fall in the four shaded autumn months. The busiest month in the record is February. An autumn month carries about 1.2 times as many uploads as an average month outside autumn. People upload most of everything in April, 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.

Ross's goose

55 research grade Ross's geese observations have been uploaded to iNaturalist for Oklahoma across every year the platform holds, and 44 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.

Greater white-fronted goose

92 research grade greater white-fronted geese observations have been uploaded to iNaturalist for Oklahoma across every year the platform holds, and 36 percent of them fall in the four shaded autumn months. The busiest month in the record is February. An autumn month carries about 1.12 times as many uploads as an average month outside autumn. People upload most of everything in April, 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

34 research grade whooping cranes observations have been uploaded to iNaturalist for Oklahoma across every year the platform holds, and 50 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.

Latest reports

What people have reported in Oklahoma lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for Oklahoma, 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.
