Sandhill cranes 2019 spring migration.
Check out this video:
Sandhill cranes fly in a “V” formation at a fairly high altitude. The image is faint as they move from right to left across the screen.
We have been lucky to be outdoors in the early afternoon frequently this spring. It appears to be the best time to see them in flight…over a half dozen times (central Indiana).

View one of Indiana’s greatest wildlife spectacles at Jasper-Pulaski Fish and Wildlife Area. Each fall, thousands of Sandhill Cranes visit the area’s shallow marshes.
I was introduced to sandhill cranes 20 years ago at the Jasper-Pulaski Fish and Wildlife Area. They feed and stay overnight during their migration. Large groups are VERY loud and not a pleasant chorus. However, it is VERY impressive and you remember their chatter. I love spotting them on the move. You hear them first!
