Arlington County Parks has invited IDA to attend a Bat Fest from 6:30 to 9:00 p.m. on Aug. 25 at Gulf Branch Nature Center in Arlington. Artificial light at night impacts bat foraging behavior in ways that are not fully understood and may interfere with navigation of bats and disrupt their circadian clocks.
