Sandhill Crane Migration - November 2020 - Northern Illinois
Here's a video that I took of them - that if you turn your volume WAAAAY up - you can hear what they sound like:
The DuPage County Forest Preserve District has this post up from one year ago that talks about these birds and their migration patterns. They mention that there's a place in Indiana that sees thousands of these guys every year. On the Jasper-Pulaski Fish and Wildlife Area DNR site, they have a count. As of this past week, they had more than more than 16K Sandhill Cranes there on site. Woah.
