Meteorological fall has begun w/ bird migration activity picking up in the #FLKeys. KBYX detects these birds as deviate echoes moving south, while showers move westward w/ atmospheric flow. Birds are seen day & night, but the nocturnal exodus (at the end) is most spectacular. pic.twitter.com/lwYumfb9Lv
