Fall Bird Migration in Ohio

Ohio's fall belongs to the western Lake Erie marshes, where the federal refuge at Ottawa says waterfowl numbers peak in October, the first tundra swans arrive with them, and sandhill cranes break out of family groups into larger feeding flocks.

Public viewing sites in Ohio

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's own season by season account puts the fall peak in October, calls fall migration more drawn out and extended than spring, and describes sandhill cranes feeding in larger flocks in the marshes once the family groups break up. Tundra swan numbers climb from that October arrival to a winter peak, when the refuge describes thousands of swans moving between its marshes and farm fields to the south. The refuge was established in 1961 and keeps a visitor centre, a boardwalk loop and a seasonal wildlife drive.

“We will see waterfowl numbers peak in October, this is usually when we see the first tundra swans arrive and if we are lucky, a snow goose.”
U.S. Fish and Wildlife Service, Ottawa 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 Ohio

U.S. Fish and Wildlife Service, Ottawa National Wildlife Refuge puts the Ohio peak at October for the peak of waterfowl numbers and the arrival of the first tundra swans, with swan numbers highest later in the winter. 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.

Ohio has no fall hawk count. The one hawk watch the state has ever run, at Conneaut on the Lake Erie shore, is a spring count that works April into early May, so the autumn record here is a waterfowl and crane record rather than a raptor one. It runs through the marshes at the western end of Lake Erie, where the federal refuge at Ottawa protects more than 8,000 acres and publishes a plain seasonal account of what moves through and when: waterfowl peaking in October, the first tundra swans with them, the occasional snow goose, and sandhill cranes gathering into larger flocks as the season turns.

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

1,835 research grade sandhill cranes observations have been uploaded to iNaturalist for Ohio across every year the platform holds, and 23 percent of them fall in the four shaded autumn months. The busiest month in the record is May. An autumn month carries about 0.58 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.

Snow goose

319 research grade snow geese observations have been uploaded to iNaturalist for Ohio across every year the platform holds, and 40 percent of them fall in the four shaded autumn months. The busiest month in the record is January. An autumn month carries about 1.32 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.

Tundra swan

543 research grade tundra swans observations have been uploaded to iNaturalist for Ohio across every year the platform holds, and 41 percent of them fall in the four shaded autumn months. The busiest month in the record is February. An autumn month carries about 1.42 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.

Latest reports

What people have reported in Ohio lately

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