Today Fireball called me outside because these guys were circling and being quite loud.
At times they were quite organized, circling and then splitting into two groups.
They would come back together and then circle again.
All the while they were slowly moving north.
I can only guess that they were migrating Snow Geese.
These are definitely not the geese we see here in the summer.
EDIT: These are evidently Sandhill Cranes.
