On my way home about 5 pm from Franklin, Williamson Co., I saw various flocks of nighthawks, all flying in one direction with focus, but not all in the same directions, however all were towards a central point (and all in Williamson Co.). I had 7 over the field with buffalo on I-65 just south of Franklin (they were headed south), while groups of about 15, 25, and 35 were seen on Hwy 840 and all going due west. I didn't stop to count closely to watch for a while (I had the kiddo with me). Oddly enough, I saw ZERO nighthawks in Rutherford Co. on my way home. Hope y'all are eBirding these nighthawk reports! Great stuff! Neat to see this many nighthawks! Good birding! Scott Somershoe
