This is interesting as well as the info. on the link Lin provided. Last year, when the Sandhills were heading back north we witnessed a spectacle right over where we live. There were hundreds of them circling in the sky making a racket which is what attracted my attention & so I watched. They circled at the same altitude & just kept that up. Meanwhile I would hear the calls of others & look to the sky south, southeast & southwest. Flocks of 50 to 100 birds would fly toward the larger group & all the while making their calls. They would join up with the original group & that group grew. We watched for over an hour & saw many large groups come join with the original group. They just kept coming & coming & the racket became so loud it could wake the dead! As each group joined the original group they fell into the circular pattern. The sky was FULL of Sandhills!!!!!! The big flock & flocks coming in from all the southerly directions. We watched for over an hour as newbies joined the big flock. Then finally I guess, everyone having joined the big flock, there had to have been a couple thousand of them at least!!!! Then & only then, when I could hear no more calls from southerly directions, the massive flock began to gain altitude in the circular flight pattern until they were just specks in the sky & their calls were very muted. Then they all seemed to move off in a northward direction. We stood still; awestruck. From watching this event we concluded they were all just joining up for the big flight to northern homes. I have never heard anyone tell of witnessing this event & we wondered if this area where we live is a staging area every year for this. I did not take any photos. I did not want to miss any of it long enough to run inside & back to the BR to get the camera.
Edit: Just realized I said last year. Amend that to last spring.
