观察细节
A very impressive congregation, especially considering this late date. We first noted 27 in a flock that was working downriver shortly after sunrise, which circled back upriver (and may have landed on the sandbar). We later found a large flock loafing on the sandbar in the middle of the river, which we confirmed to be FRGU by zooming in on photos. DFL estimated ~95 when the flock was perched in tight formation, but in two in-flight images, CLR counted 117 and 124 FRGUs ! This tally may be second only to Van's flight of 645 from nearby along the Mississippi River in Oct 2012: https://ebird.org/checklist/S11830903
