The Minnesota River Valley Audubon Chapter (MRVAC) hosted Travis Longcore’s presentation on light pollution and bird conservation Thursday, March 27 at 7:30 p.m. Light pollution is an additional stress on bird populations, exacerbating other threats. Urban ecologist Dr. Travis Longcore presented wide-ranging research in this important area and how it intersects with other important threats to birds such as glass collisions. He showed how artificial light at night can disrupt the orientation of birds during night flights and how it affects critical behaviors linked to light cues, including the timing of migration, timing of the dawn chorus and even the production of stress hormones and susceptibility to disease.
