UNCSA 9 Jul 22 Chimney Swifts #1

I left school (UNC School of the Arts in Winston-Salem, NC) just before dusk around 9 pm tonight, and heard the twitter of swifts. By the time their swirling finished for the night, several hundred swifts had descended into the chimney on Gray Building by about 9:15 pm. (Here they are still swirling.)
