WFAA Article submitted by Donna Cole, 2002 – Light pollution in cities like Dallas can disorient birds migrating at night, which may cause them to collide into buildings as a result.

One such building participating in the initiative will be Reunion Tower, which will be dimming from midnight to 8 a.m. on Earth Day, and again that night from 7 p.m. to 11:59 p.m. For the remainder of the migratory period, the tower will be dimming its lights at 50% output from dusk to 111 p.m., go fully dark from 11 p.m. to 6 a.m., and 50% output again from 6 a.m. to sunrise.
