Media notes
This is the most of the main flock. I repeatedly estimated 400+ birds in this flock, but it was growing during the period of observation and was probably up to 500+ by the time I'd left. Many of the birds on the wing landed in this flock, but some also kept on going.
Observation details
At least this number, perhaps many more. See media and analysis, below. Also, video of the flock here: https://www.facebook.com/ted.floyd.54/videos/2313760148685037/
