Fall Bird Migration in Alabama

Sandhill cranes pour into the Tennessee Valley from late November, and the refuge that holds them keeps a heated observation building at the end of a 200 yard trail behind its visitor center.

Public viewing sites in Alabama

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 trails page describes a 200 yard trail that begins behind the visitor center and ends at the observation building, and says that in winter hundreds of ducks and geese and thousands of sandhill cranes use the area in front of it. The refuge calendar has the cranes arriving in late November and peaking in early January, waterfowl and crane numbers at their highest in the latter part of December, and whooping cranes wintering here every year since 2006. The visitor center is at 3121 Visitor Center Road, Decatur, and from November through February it opens seven days a week, 9 a.m. to 5 p.m.

“During winter months, hundreds of ducks and geese, and thousands of Sandhill cranes use the area for feeding and loafing.”

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 Alabama

ADCNR sandhill crane account and U.S. Fish and Wildlife Service, Wheeler National Wildlife Refuge seasonal calendar puts the Alabama peak at ADCNR says thousands of cranes rest along the Tennessee Valley from October through April; Wheeler refuge says the cranes begin arriving in late November, that waterfowl and crane numbers peak in the latter part of December, and that crane numbers peak again in early January. 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.

Alabama's share of the fall migration is a waterfowl and crane story, and it belongs almost entirely to one place. The Tennessee River runs west across the top of the state, and Wheeler refuge sits on the widest part of it, with impoundments and crop fields that hold the birds through the winter. The state agency's own account of the sandhill crane says it is not uncommon to see thousands of cranes in northeast Alabama resting along the Tennessee Valley from October through April, and the refuge fixes that to months: geese from the latter part of September, good concentrations by the end of October, cranes from late November, everything at its peak around the turn of the year. The refuge also holds the only regular wintering whooping cranes in the state, part of the reintroduced eastern flock, which have returned every year since 2006. There is no counted hawk ridge in Alabama that reports a fall season.

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

858 research grade sandhill cranes observations have been uploaded to iNaturalist for Alabama across every year the platform holds, and 37 percent of them fall in the four shaded autumn months. The busiest month in the record is January. An autumn month carries about 1.17 times as many uploads as an average month outside autumn. People upload most of everything in September, 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

218 research grade snow geese observations have been uploaded to iNaturalist for Alabama across every year the platform holds, and 57 percent of them fall in the four shaded autumn months. The busiest month in the record is December. An autumn month carries about 2.69 times as many uploads as an average month outside autumn. People upload most of everything in September, 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

259 research grade whooping cranes observations have been uploaded to iNaturalist for Alabama across every year the platform holds, and 51 percent of them fall in the four shaded autumn months. The busiest month in the record is January. An autumn month carries about 2.08 times as many uploads as an average month outside autumn. People upload most of everything in September, 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.

What people have reported in Alabama lately

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