But the birdiest night of fall migration peaked in neighboring Alabama, wherein 33 million birds flew over Stanley Baldwin County the nighttime of October 16—the very best nightly general for any county.
These bragging-rights stats come from the new on line Migration Dashboard produced with the aid of BirdCast, a collaboration amongst scientists on the Cornell Lab of Ornithology.
Colorado State University, and University of Massachusetts Amherst that uses climate radar and machine learning to track and forecast hen migration. BirdCast has been monitoring nightly fowl migration through radar across the U.S.A. Seeing that 2018, but last spring this system released the Dashboard tool to provide real-time migration statistics at the county level.

Migration Dashboard offers actual-time analytics about nocturnal fowl migration, inclusive of flight speed, path, and altitude. In fall 2021, BirdCast indicated that southern states like Alabama and Georgia had the highest volumes of migrating birds, which makes perfect experience to radar ornithologists like Farnsworth and Adriaan Dokter.
There’s constantly an inclination for migration to pay attention east of the Gulf [of Mexico],” stated Dokter, a research associate on the Cornell Lab and member of the BirdCast crew. The reasons, he said, lie inside the simple wishes of migrating birds: habitat, meals, and favorable winds.
In autumn as birds flow south from their breeding grounds, they are seeking out big swaths of woodland to safe haven and refuel during their grueling journeys.
Dokter stated that the Appalachian Mountains—that are essentially 1,500 miles of unbroken bushes strolling from Canada to the Deep South—is in particular engaging for migrants. The mountains collect birds from across the East, funneling them to the variety’s southernmost factors in Georgia and Alabama.
Large numbers of birds additionally migrate via Midwestern states like Iowa and Missouri. When flying on favorable tailwinds (this is, winds blowing out of the north), migrating birds tend to flow eastward because of winning west-to-east winds across the continent. Again, the birds are driven toward Georgia and Alabama.
New BirdCast Dashboard Spotlights the Hottest States and Counties for Bird Migration
This confluence of chook-migration rivers—where birds flying down the Appalachians meet birds drifting over from the Midwest makes the Southeast a hub for nocturnal hen air traffic. The maximum-extent hen-migration nights are dictated by way of weather.

Birds love emigrate with top tailwinds,” said Dokter. Indeed, the three largest hen migration nights in fall 2021—on Sept. 22, Oct. 3, and Oct. 16—have been all the end result of high strain structures that introduced bloodless weather and favorable tailwinds out of the north. But Dokter theorizes there’s a difference inside the make-up of species on the ones three massive migration nights.
It’s very possibly the primary top is greater long-distance migrants,” he stated. Later we see birds that live inside the U.S. To winter.” In other phrases, birds like warblers that migrate all the manner to Central and South America go away first, while sparrows and kinglets which have less floor to cover migrate later.
As for fall 2022, Dokter says the new BirdCast device provides a new element to birding the autumn migration. I’m going to take a seat there with Migration Dashboard, go searching, and allow the birds surprise me,” he says.
